Lisa asks…

Should OPEC be allowed to cut supply to raise the raise the price of oil?

First I just want to say if I’m incorrect in my understanding of how this works I would really appreciate being corrected by someone who can explain this fully and accurately.

i heard on the news that OPEC is getting together to discuss cutting output to lower supply so that the price of oil goes up.
If we have to deal with the fluctuations of the market impacting the price we pay for gas, why do they have the ability to make us pay more?

lol dont mind the error in the title 😛

admin answers:

Actually, the real story is much deeper, and has a lot to do with our current Recession. There has been a behind doors deal struck by the puppeteers who pull the strings of all the nations’ leaders, essentially, we are letting them gouge us on oil, but we’re buying it on credit, and at the same time, China and others are buying Our debt, essentially paying for Our oil in exchange for a promise to pay them back later. We did this back in 1910, only we reneged on paying our debts then, and, as the story goes, We will repeat history. This was a dangerous game, with serious consequences. Now, these terrorist nations have amassed incredible wealth, but they are running out of oil. They continue to quote the same amount of oil they had 20 years ago, with No more new discoveries. Many believe our world oil supplies are infinite. The fact is, we, in the U.S., now have more oil in One oil field than the entire Middle East now has. Count our friends, you Canadians up north, and we have lots of oil, though your tar sands cost a lot more to retrieve; our best source uses new technology to get it out of the ground, but it only costs us $16 a barrel (yours is only $35-$45 a barrel to retrieve) for the light sweet crude-the desirable stuff. But we have given a lot of wealth to some dangerous countries, and we owe a lot of money to China (and others), who we really don’t want to make an enemy. China has developed a new technology that turns coal into clean burning oil for around $35 a barrel of oil, and they have 5 giant refineries going up. We have licensed this technology, and are building a refinery 1/6th the size of one of China’s. We passed laws that have limited our Refining capabilities (it was, in reality, meant to keep the oil companies, who own the refineries, quite wealthy; the refinery is the spigot that let’s Us control the supply, just as OPEC is threatening to control the supply they control. There are a lot of rich leeches getting rich off expensive oil/gas at the little guy’s expense, and they want You in the dark about all of what I am telling you. The fact is, with some simple changes in law, we can have all the coal oil we want at $35/barrel, we are currently getting lots at $16 a barrel, you hosers in Canada have plenty at $35 a barrel, and that’s all without touching ANWR in Alaska or offshore, which we can do in an eco friendly way. Basically, the play is to drain the dangerous countries dry, then and only then, do we begin supplying All our own energy needs here. Hybrids will give way to better, cleaner, more powerful Diesel vehicles, and T. Boone Pickens will be putting his Wind Generation Plants while I’ll be launching my more powerful CSP(Concentrated Solar Power) plants here in Sunny, Lovely New Mexico, and supplemental wind turbine and Solar power generators on every house in the proper climate that will get them to near zero consumption, while the CSP Plants will have enough power for the nation…and hey, we may even send a bit up to ya hosers up north, eh?
So, though we’ll never see gas under $2 a gallon, it will return to around that quite soon, and I myself will be in a zero consumption house with a plug in electric car (another project of mine coming up), either one of my own design, or perhaps one of the five that can already leave a porsche in the dust. Power now, cheaper and cleaner power for the future, an electric car (1cent per mile) in every garage, with zero consumption housing, paying for off peak power, selling back at a premium excess generation at peak hours for premium cleaner, renewable energy… heck, they were right….I Should have run for president! :o)~ Or if more people would quit watching MSM (Mainstream Media) and get their news off the internet or other alternative sources, we could have the Greatest President ever entering office within 3 weeks….Ron Paul, Doctor, Representative, and a darn good man. Hey, don’t blame me….I tried to get him elected. Just to keep my conscience clear, I’ll be writing him in as my Candidate…. Maybe if enough people do that, we can end our suffering. He got 28% of the vote here in New Mexico when MSM stated McCain was running opposed, and the final state, Montana, gave him 31%. Do we really want to wait four more years for a chance to get Real change, or can we got off our couches, get out, and write in this great man for President? Go see his at least. Love and Peace.

Jenny asks…

Has the USA shot itself in the foot with over-the-edge environmental laws?

The environmentalists campaign against smokestack industry in the USA has driven these industries and their jobs out of the country to places where environmental laws are less strict.
We cannot even build dams for clean hydroelectric power because it displaces fish. Even wind generated power is fought because the generators are unsightly on the horizon.
We cannot drill for our own oil because it will disturb frozen dirt in Alaska.
Are restrictive envirnomental laws choking our economy?

admin answers:

Not necessarily. The USA is far behind most developed countries in environmental standards, which is disappointing because we have the ability to easily solve our energy problems if we would just commit ourselves to it. I believe we can abide by environmental laws, come up with solutions, and protect the environment. It doesn’t have to be one or the other. We don’t have to choose between the earth and the economy like some people make it out to be.

Your Questions About Wind Turbines Colorado

Sandy asks…

What can we do to combat global warming and save our atmosphere from destruction?

admin answers:

We shut off the hot air coming from the deniers that concocted most of your answers.

The truth is that it is urgent that we take these steps, regardless of global warming. There are
so many ways we are harming the environment.
And they are mostly the same ways we are warming the planet.

Conserve in every way we can.
That is said to be one of the biggest improvements we can make.

Enact national policies that encourage investment in alternative energy.

Limit destruction of forests. Improve logging practices. It can be done more sustainably. Use hemp to make paper and other products.
Too much deforestation is for making paper.
Bamboo is more sustainable than trees, also.

Use farm waste to harness methane, thereby limiting a greenhouse gas,and producing energy at the same time.

“Wild Rose Dairy in Webster Township, WI is home to an innovative renewable energy facility powered by cow manure and other organic waste. The farm is home to 900 dairy cows, and an on-site anaerobic digester creates methane-rich biogas from their waste, which is used to generate 750 kilowatts of electricity per hour—enough to power 600 local homes 24/7.”


“The gas produced by Huckabay will be shipped via the Enterprise natural gas pipeline to the Lower Colorado River Authority, which has agreed to purchase the RNG® output of
up to 2,000 mmbtu per day through September 2008, pursuant to a purchase agreement. Beginning October 2008, the plant output will be sold to Pacific Gas & Electric under a 10 year
agreement.” from the website of Environmental Power. They have four of these on large farms in the California Central Valley.

Build a mainly solar electric grid, which is feasable right now and economical. Solar thermal and concentrating PV power plants in the southwest could power the entire country with current technology at competitive prices with coal and gas.
Scientific America Solar Grand Plan

“Solar thermal power plants such as Ausra’s generate electricity by driving steam turbines with sunshine. Ausra’s solar concentrators boil water with focused sunlight, and produce electricity at prices directly competitive with gas- and coal-fired electric power.”

“All of America’s needs for electric power – the entire US grid, night and day – can be generated with Ausra’s current technology using a square parcel of land 92 miles on a side. For comparison, this is less than 1% of America’s deserts, less land than currently in use in the U.S. For coal mines.” from Ausra’s website

More wind farms.

More efficient cars and trucks.

Use parasails for power assist on cargo ships. We already have this ability to save 10-30% of their fuel costs, with an investment per ship of about $250,000. Large dry bulk ships lease at over $100,000 a day, so this is chump change for shipping companies. These parasails provide 6,800hp of auxilary power.


Rely more on rail rather than trucks for much of our overland freight. It is much more fuel efficient.

Somehow manage to become less of a consumerism society and economic system. Which might mean learning contentment, which wouldn’t be a bad thing. Consumerism is really an aberation from real capitalism. It is extremely wasteful.
To see a short video about how consumerism works in our world.

This is an obviously left leaning video, but whether you’re conservative or liberal, you’ll see a lot of truth in it.

Linda asks…

How do you feel about the current gas prices?

Does it seem like the “war” is against US citizens- being forced to make corporate top brass record profits? If our “war” is to look out for the best interest of the US- then shouldn’t we be “fighting” corporate rip-offs of the American public- S-n-L Scandal- Enron- Oil- etc.?

admin answers:

There are a number of things that can be done about gas prices. The problem is that there are political, environmental, and legal issues that would have to be overcome to make it happen.

First, we need to reduce dependence on imported oil. As a world wide commodity, changes in oil demand anywhere in the world will impact our prices here. We could reduce oil imports by increasing the use of ethanol. Currently something like 25% of the US corn crop goes to this. However, the downside is that this takes corn out of the stockpile for food (both human and animal feed), which is currently causing famine to break out around the world. We could expand domestic supply, but hat means drilling for oil off the Gulf coast and in a part of ANWAR, which has environmentalists up in arms.

Second, we could improve the distribution of fuel in the US. Currently, there are dozens of gas blends, all mandated by law. It is a tricky thing to supply just enough of each blend, as you cannot use a blend intended for, say, Colorado, in California. So if California goes in need, oil companies cannot shift inventory, they have to shut down refineries, make adjustments, and make more of the California blend. This is a wasteful and expensive process. Far better to have a single blend that all the states can agree on that would allow the fluidity needed in the market. But this is going to be difficult to impossible as the states want THEIR blend and will fight any kind of Federal mandate.

Third, I think we need to encourage those things which will get us away from oil consumption. Not much oil is used for electricity generation, but it can and should be replaced by more efficient, cleaner sources. But nuclear, coal, solar, wind, and hydroelectric all have their own problems as well and each industry will fight hard for their slice of the pie. Most oil is used for vehicle fuel. We need to move to more efficient vehicles and alternative fuel / hybrids, but they are often more expensive than gasoline powered vehicles and some alternate power sources do not have the power necessary for today’s driving. Research needs to be done in fuel cell technology, advanced batteries, and efficient (and safe) hydrogen generation.

I think too many people focus on one thing (conservation, more oil drilling, whatever) and think that alone will solve our problem. They are wrong. It will take a comprehensive approach were everyone will have to give a little for the greater good. Rep. Kennedy is going to have to sacrifice some of his coastal view in MA for wind turbines. Oil companies are going to be allowed to develop domestic sources. States are going to have to grant the feds the power to set uniform fuel standards. This is a lot to ask for, but this and more is what it will take. Anything less then an across the board rethinking of our energy policy will be like slapping a band-aid on a cut artery; just too little to be effective. And if it is ineffective, then expect the President of Iran to be correct when he says that oil is a strategic resource that needs to find its true (and in his mind MUCH higher) price. This is the guy that thinks $200 a barrel for oil is not unreasonable.

Your Questions About Wind Turbine Generators Manufacturers

Sandra asks…

What is the Ram Air Turbine(RAT) in aircraft? When and what is it used for?

I saw a photo of a Boeing 777-300 going around with the RAT deployed. Can anyone please tell me why it is required during a go around?

admin answers:

A main generator and or an APU failure could trigger an “auto deploy” on that aircraft. If the aircraft is in air mode but really on the ground an external power failure could do it too. Look out because it is not small! :0

A ram air turbine (RAT) is a small propeller and connected hydraulic pump, or electrical generator used as an emergency power source for aircraft. In case of the loss of both primary and auxiliary power sources the RAT will power vital systems (flight controls, linked hydraulics and also flight-critical instrumentation). Some RATs produce only hydraulic power, that is then used to power electrical generators.

Modern aircraft generate power through the main engines or an additional fuel-burning turbine called an auxiliary power unit, which is often a small tail-mounted turbine engine. The RAT generates power from the airstream due to the speed of the aircraft, and if aircraft speeds are low the RAT will produce less power. In normal conditions the RAT is retracted into the fuselage (or wing), deploying automatically in emergency power loss. In the time between power loss and RAT deployment, batteries are used.

Some manufacturers call them ADG”s (Air Driven Generators), and some run a reverse system called a HMG (hydraulic motor generator) which has a similar function but achieves it in a different way. Sorry wiki didn’t have an article about that 🙁 maybe I will write one!

In a controlled field, the local controller may instruct the pilot to go around if there is an aircraft, vehicle or object on the runway or some other unsafe condition. In both controlled and uncontrolled fields, the pilot in command may decide to go around at any time, for example if the aircraft is not lined up or configured properly for a safe landing; an aircraft, vehicle or other object has not cleared the runway; no landing clearance was received (in a controlled field); the landing gear is not properly extended; a dangerous meteorological condition is experienced on final approach (e.g. Poor visibility, excessive cross-winds, etc.); or some other unsafe condition is detected.

Flights conducted under instrument flight rules, including all airline traffic, refer to “executing the missed approach” rather than going around. The maneuver itself is the same, but the pilot instead follows a pre-defined navigational “missed approach” sequence, published on the approach chart, instead of entering a circuit or pattern. Absent further instructions from the controller, a missed approach sequence directs an aircraft around traffic patterns and terrain into a safe place to begin a holding pattern.

Wind Energy FAQ
What do I need to know to purchase a residential wind turbine?
Will my utility allow me to hook up a wind generator?

Federal regulations (specifically, the Public Utility Regulatory Policies Act of 1978, or PURPA) require utilities to connect with and purchase power from small (less than 80 MW) wind energy systems. A wind turbine manufacturer should be able to help arrange the required utility company approvals.

See State-by-State small wind information for lists of interconnection requirements for many U.S. States.

Your Questions About Wind Generators Home Use

James asks…

How big a generator do I need to run the essentials for a home, including a well pump?

We are wanting to purchase a generator for emergenices, but how big do we need one to be? I am especially interested in the running of our well pump for water (we are in a rural area). What type of generator would work best? Are there solar alternatives?

admin answers:

The smallest I would recommend is 5000 watts. This should be enough to operate the well pump, small cooking appliances, lights, television, fridge, etc. Power will be limited and you will have to be careful not to overload the generator. I power my house with a 5500 watt generator. You should also consider installation of a proper transfer switch and be aware of the dangers of carbon monoxide poisoning.
Read through my generator page listed below for more information.

If your main goal is to power the well pump solar or wind are not feasible. The power requirements are simply too high. It may be an option to supplement your electrical consumption for other smaller loads however.

Betty asks…

How can do I make a home made electric generator?

I will like to know how I can make a home made electric generator. I know you can buy them today for cheap but I tought it would be a fun project.

admin answers:

I’m not sure from your question what you want to make, the generator itself or a system that generates power?

The generator itself would be very difficult for home production. Take apart a car alternator or starter motor (which would work as a generator) and see whats involved. Using these same items to generate power from another source such as wind is perfectly reasonable to do with directions how available on the Internet.

Having said that, if you just wanted to make something that worked but wasn’t actually practical, take a look at the link
This would work as an ac generator if the ends of the wire wound on the cork were connected to some type of collector ring and brushes and the needle turned by something

Windmill Jobs or Wind Power Jobs?

How can someone get wind power jobs working on the windmills made by GE? I have seen commercials and read about them in the local paper saying how these new green jobs pay well and are the fastest growing job market in the US but I don’t know what it takes to get a job with General Electric working on their windmills. I am looking for more info about what I need to do to get a wind industry job. Any info about what I could expect as a salary would also be appreciated.

admin answers:

Windmill jobs are growing in demand and what you can make as a yearly salary in the wind industry depends on your specific job. Wind Technicians, also called a wind tech is someone who repairs and maintains windmills (Wind Turbines) and they make over $80,000 per year. These positions require some technical knowledge and this can be gained by going through an accelerated wind tech training course like California Wind Tech or AEI. If I was you I would do some more research by visiting:

Your Questions About Wind Turbine Generators For Home Use

Lisa asks…

Should we have little windmills on our homes instead of solar penals?

In winter, when we want warm water, there is none because solar penals only work when the sun is strong. In summer, when we use less warm water, we waste a lot because solar penals are working overtime. This technology is stupid, unreliable and extremely costly in winter. Would little wind mills on our homes be more efficient?

Is there any way pedal power could conduct electricity? We’re the world’s fattest nation so if we could transfer energy into our homes from say an exercise bike if this is possible? Wouldnt that be good?

admin answers:

I assume by solar panels, you are talking about solar water heating. I can tell you for a fact, they work great in the winter heating my water. I have 2 feet of snow on the ground in Massachusetts, USA, and I had 160 degree F water coming from the panels yesterday when I checked. Systems that are correctly sized will provide 100% of your hot water in the summer, and 50% in the winter. So your backup heater only has to work half of the time in the winter, and never in the summer. There is nothing stupid, costly, or unreliable about that.

Wind turbines need to be 30 feet above any obstacle within 300 feet. That includes your house. So you would need a very tall tower if you don’t have a lot of land to keep it away from the house. You also need to have at least 10 mile per hour windspeed average to make the expense of a wind turbine worth while. For houses that meet that criteria, wind can be a great option. But most houses do not.

There are generators that run off an exercise bike. I’ve heard of parents only letting their kids watch TV if they are powering it by bike. I love it. But they don’t generate enough power to run much else.

Helen asks…

How many solar panels with one wind generator would you need to power a pop up?

I am looking at buying a pop up and would like to make it run off of deep cycle batteries but charging these batteries I would like to use a combination of solar panels and 1 wind generator. How many batteries would I need how many solar panels and what wind generator should I buy. I would be powering the lights an fridge and sometimes a AC or Heater.

I live in west Texas where it never rains and its always windy

admin answers:

Hope it’s not cloudy without wind for a while, you’ll be left with warm food and darkness.

An air conditioner/heater would be such a huge load on the system, wind/solar most likely don’t make sense for an individual, unless you’re on a lake or in California where it’s sunny everyday.

You would need around 200 W for a fridge, 100 W for small lights, and….500 W (?) for heating/air….so you’re looking at some pretty big batteries!! Every 2 hours you will use at least 1.5 kWh of energy.

Jenny asks…

Whats the best motor to use to convert into a 6v wind generator?

Whats the best motor to use to convert into a 6v wind generator?

admin answers:

From your other questions, it appears that you want to set up a demonstration to power a small motor with the wind generator. Your 1.5 – 3V motor is probably a permanent magnet DC hobby motor. It would probably be best to use an identical motor for your wind generator. If you use something that is very much larger, you may need a larger wind turbine and more wind than you expect to need. If you want something that is just a little larger, you might look for a slightly larger motor that is similar to the one you want to power.

Your Questions About Wind Turbines Colorado

Nancy asks…

Is it possible to change a desert climate to a more greener and cooler climate?

I have few ideas such as using several large fountains in series that shoot sea water into the air hundereds of meters to cool the surrounding area. This may effect the dessert climate in a way that it may start to eventually cool the atmosphere and bring in cool air currents. The fountains would take seawater from the nearby seas that surround a particular country and by using gas turbine pumps send the water high into the atmosphere. There would be a byproduct of this process in that it will create seawater lakes that may also contribute to cooling the local area.

Also, as the water falls it will draw in cooler upper atmoshpere air similar to what happens in rain squals when wind is generated by the falling rain drops.

admin answers:

That is an interesting concept. It might actually work if things get terribly desperate.

It would require a tremendous amount of energy to do that so I fear even if it would work the cost would overrule the benefits.
Besides the jets of water being blasted high into the air would be a hazard to airplanes. Heh heh heh. Imagine, flooded engines at 30,000 feet!
The high altitude jets of water might provide sufficient cooling to cause a drop in temperatures but the salt would get blown far and wide and could cause a great deal of trouble. Crops can’t grow in salty soil and who knows how far the wind might carry it?

Deserts are extremely dry and would rapidly absorb most of the water pumped into any lakes. That would provide some cooling but I fear not enough.

One approach that has been shown to work is to build machinery to remove the salt and pump the water directly to areas of the desert where crops can be grown by using slow drip irrigation. Trees and plants can grow right in the area where the water is fed in a constant drip. The shade from the trees would provide some cooling effect. The time is coming when more countries will have to make the move to that system to feed their people.

Even California in the U.S. May have to do that because they have far more people than they have water for. California pays farmers NOT to use water from the Colorado river so they can have it for their cities!!

That could certainly benefit Mexico and many countries in Africa.

I like that you are thinking about the problem. There is no such thing as a bad idea. Every idea has some merits and eventually with enough ideas we can solve any problem that doesn’t involve human nature.

Keep those creative thoughts flowing, practice makes perfect…..

Linda asks…

what are the three least used energy sources in the world?

is it ,
hydroelectricity, wind and what ?
i forgot my textbook at school

admin answers:

Geothermal. This is because one needs a volcanic region for the geysers to drive the turbines. Iceland has lots of them and this makes Hydrogen cheap enough to use as a fuel. This makes Hydrogen fuel also very rarely used. Generating the electricity needed to produce this gas from water takes enormous amounts of energy. Solar power is not used domestically in America because of all the lobbying done by coal and petroleum companies to limit its development, but the Europeans use it quite a lot. There also has not been a nuclear power plant built in America for decades because of the public fear of nuclear accidents. Again, the Europeans use this form of energy generation extensively, especially the French. Hydroelectric generation is limited only by the presence of rivers to dam. The colorado river is dammed in many places and China’s three gorges damn is the largest hydroelectric power plant in the world. American lobbyists also had an initial negative impact on wind power, but the sheer efficiency of a turbine makes them a viable power source, no matter whether they are a visual isore or not.

George asks…

How many gallons of OIL does it take to make ONE Wind Turbine?

It takes 8 gallons of oil to produce ONE TIRE. Can you imagine all the oil it would take to build one of those enormous Wind Turbines? How many gallons would it take to make a solar panel- when both combined only produce 2% of what we really need. Its BS!

The real reason govt is banning Edison bulbs is they are too cheap and GE can’t make profits so they will force us to buy those squiggly bulbs filled with MERCURY paying like 7 bucks for one BULB!

admin answers:

Hey Soros, it isn’t BS, I’ll explain. This issue of, “Embodied energy,” keeps coming up again and again, but for some reason, it only seems to apply to solar and wind. Nobody ever questions how much oil it takes to build a coal fired electric plant, or a nuclear one. For some reason, it’s as if it doesn’t matter.

First, there have been studies done on the embodied energy requirements for various renewable energy devices. Solar panels generally take between 1.5 and 6 years to, “earn back,” their embodied energy. The range has to do with where the silicone was first mined, then refined, and how far the panel had to be shipped before final installation. Almost all panels today are warrantied for at least 25 years, and generally they last much longer than this. For wind turbines, the timeline is actually a bit shorter, 2 – 4 years, but it is a little harder to get an exact number on because they come in such a range of sizes. The largest solar panels don’t measure much over about 300 watts, one person could actually carry it back to their remote cabin on foot. Most wind turbines do not have this option. But in the end, none of this matters.

Electricity has been around for over a century now, so it isn’t going away anytime soon. The question is, “What is the best way to produce it?” Let’s say you took a modern wind turbine powerful enough to run a small neighborhood, maybe 25 KW. Then you put it along side a similar sized natural gas fired turbine generator. Which device earns back its embodied energy sooner? Turns out the natural gas turbine never does. We forget that once you invest the energy to build, ship and install a gas powered generator, you now have to keep feeding it natural gas for the rest of its life, so in the end it keeps digging itself a deeper and deeper embodied energy hole that it can never crawl out of. At least the wind turbine will get even some day, and later will be some distance ahead environmentally. The same is true for coal, oil and yes, even uranium.

As far as the government banning something so the producer can stop making something that offers them no profit, I can assure you if GE, Sylvania or Phillips did not make profits on incandescent bulbs, they would stop making them without the governments input on the matter. You can buy into whichever consipiracy you like, but if you have not taken the time to write your congressperson on the matter, then the decisions in this world will be made without your input. We’ve been pining for an end to those old energy hog bulbs for years, and now it looks like it might happen. Did you know when you turn on a 100 watt incandescent light, 96 watts are converted to heat, and the other 4 are converted to light? Each watt of input equates to 3.35 BTU’s of heat, so that 100 watt bulb is also adding over 300 BTU’s of heat to your home. If you are running an air conditioner, it will have to work that much harder to cool your home, so now you are wasting energy at the bulb, and again at the compressor. This is why those squiggly little bulbs can pay for themselves in half the time in an air conditioned home. You might now be thinking that using those old bulbs is an excellent way to heat your home? It would cost exactly the same as running an electric heater to do the job, this is why most people use natural gas or oil to do the job, it costs less.

Like Roderick, we power our home with the wind and sun. We’ve been doing it for about 11 years now. I really couldn’t tell you exactly how much energy our equipment makes, but our electric bills come in at about 5 – 10 dollars a month now, so I know we are getting ahead. Making your own electricity is not for everyone, it requires expensive equipment and some TLC over time. Some people grow their own tomatoes even though it might be cheaper to buy them at the store, for them it’s a hobby, we just grow electrons in our garden. While we may not get our cash investment back over time, I know we are getting our energy investment back, and will again and again as time goes on. There are some excellent websites you can check out on the subject, I’ll list some below. Take care, Rudydoo

How do I power a lighting fixture with a wind turbine?

I don’t need a lecture on the wonders of “green energy”, the benefits, blah, blah, blah. I am not hooking up to the “power grid” and I really don’t care about the “community”. I want a nuts and bolts answer. I’m making a small vertical spin wind turbine, and I just want to power one or two security lights. No, I don’t want to use solar power, too unreliable. What kind of generator and voltage regulator do I need? Do I need storage batteries? Wiring? Etc. Thanks!

admin answers:

Sorry, but wind insn’t any more reliable than solar, and a lot of the same problems apply.
Your turbine set-up needs to gather/store enough energy to run your lights for the night.
For a home-built set-up, your best bet is an automotive alternator/regulator and batteries.
Use a 12V. Controller and lamps, and save the expense of an inverter.

Governor Sanford Announces Opposition to Coal-Fired Plant
Columbia, S.C. – February 11, 2009 – Governor Mark Sanford today announced his opposition to a proposed coal-fired power plant to be built by Santee-Cooper in Florence County, saying that projections related to the need for the plant need to be revisited, along with the potential for harm to the state’s environment.

“Everyone involved agrees that building this coal-fired plant is a short-term solution to bridge the gap between now and the time more nuclear capacity comes online,” Gov. Sanford said. “We have a great deal of respect for many of the decision makers in this process and many of the advocates who have pushed so hard for this plant to be built. To that end, I’d single out O.L. Thompson for his leadership of Santee Cooper, and given what’s at stake here I’d thank him in particular for his thoughtful approach to everything he works on.

“In that same vein, I’d respectfully suggest that the environmental community be equally thoughtful in making a choice. It’s simply not realistic to suggest that neither coal nor nuclear is acceptable, because like it or not, one or the other must come our way as our state grows over time. To that end, I’d ask the environmental community to indeed embrace nuclear power as an alternative to the coal-fired plant proposal, for the advantages it has in terms of cleaner emissions.”

Governor Sanford laid out four broad concerns about the coal-fired plant proposal:

– Construction and operating costs – On Friday, the Obama Administration said it intended to reverse Bush Administration policies related to not capping mercury emissions, with action carbon dioxide emissions expected to follow. Those forthcoming caps have not yet been factored in to the cost of building and operating the plant. For this reason on Monday, Nevada Power canceled plans for a $5 billion coal fired plant in that state.

– Pollution – The proposed plant would have a significant negative impact on air quality and increase mercury pollution. The plant would emit the equivalent of 2.3 million cars in carbon dioxide yearly, and nearly 15 million cars’ worth of particulate matter.

– Growth projections – Given Santee Cooper’s overall decrease in power sold last year and a statewide slowdown in new home construction, the growth projections that showed the need for the plant need to be revisited.

– Coal prices – Unpredictability in the global commodities market may make the coal needed to run the plant more expensive than originally anticipated.

So..There are several forces at work here
Environmental groups including Al Gore and Co.

Obama administration / agenda.

A state governor who [to my amazement] is basing his decision ‘in part’ on a bet Against Future Growth in his state. (what does this pessimistic attitude say about us?)

Feel free to add to this list.

IMO..The time for a half azzed approach to energy independence is long gone. Let’s get in gear and enlist the private sector to Make Coal Plants Cleaner! We have LOTS of coal so let’s get the damned things built! Same with the Nuclear Plants. If the wishy-washy French can do it then what about the Land of the Free and the Home of the Brave! As we speak the Obama administration is pushing to put More taxes and Restrictions on the production and sale of Natural Gas! This is one area which shows real promise because of huge new deposits that have been found On Our Soil in the past few years.

Isn’t it time to get in gear and stop playing games with our Independence? Can’t means Don’t Want To!
(( I understand that the Governor is making a choice to focus on nuclear based on budget constraints and long term advantages but if we are serious about this then we need to take advantage of All viable at home! ))
I hear ya,that 10 year goal for ‘alternatives’ sounds good on paper but the problem is we’re walking across a field of diamonds to find a few ‘possible’ gold nuggets!
Edge1: What’s up Bro? All the more reason to keep the damned feds out of you state business! What’s good for New York may not work in Vegas.
Looks like the Irish are fired up today!
cons/mom: I heard it and I remember it well!
UGOT2B: Amen!
Libertarian Soul: I’m not knocking Sanford here. He’s fighting a hydra-headed monster!
Ol’Foolosifer/Edge1: What about this combination? Nuclear for major cities. In rural ares take advantage of what we have in abundance..sunshine and natural gas. Each home could have solar panels and each community could have a generation station of generators run off of natural gas. Here in Ga. some counties invested in deep water wells as a back-up in case of a drought and sure enough we just went through one and those counties were sitting pretty!

You know the feds hate this idea..too much independence for us is bad for them!
Canam: “His opposition to this coal plant does indeed have gore and obama written all over it”

Thank you. That’s the first thing that jumped out at me. He’s being Black-mailed!
Sash: I saw the replay of that speech today. You can see why they hate him and Coulter so much. That truth stuff is scary to them.
blue: My condolences. I forgot you live in RINOland. I have family out there and ther’re ready to storm the castle walls! I’ve noticed you have a very good memory and you’re ON them every step of the way. Keep your doors locked and be alert. They may decide you’re a good lobotomy candiidate. I’m not giving up on trying to convince you to trade in that framing hammer for a S&W revolver.
Dropshort: Believe it or nt AL GORE has hi sticky fingers in that too! They’re worried that it’ll disrupt the mating habbits of some damned desert rat or some such critter. No I’m not kidding!
John: I’m with ya!
neurotic: He is big on that pie in the sky crap isn’t he. It’s time do the business or get off the pot!

admin answers:

While I’ll admit that coal fire power is a pollutant, at this present time we could use it to boost the grid and lower costs of power. The problem is, it takes longer to build a nuke plant and more safeties must be in place. I believe in using what we must as a stop gap until the Green Industry catches up and this could take several years to do.
True Solar power would be best as far as emissions are concerned, but this is also more expensive to set up and when there is no sun shine for several days this could be a problem.
When Con-Edison first started up, each neighborhood had their own generators, which covered a certain area. This agenda could be used again with the solar idea and by doing so, could reduce costs to those in their areas if they would also set up solar panels to help in producing their own power and if any was not used it could be diverted into the grid and help the other areas.
I believe through a system of wind, coal, nuclear, solar and even water powered generators we could produce much more than we need, by combining the grids of each.

Edit: If I could find a way to run my house without the need of any outside influence I would build a high fence around it of stone and secede from the union. Welcome to the free nation of Liberty!

Mandy asks…

Californians! Are you furious?

In the midst of the highest unemployment rate, foreclosures, well lets face it… a depression, we just got soaked with huge tax increases for the right to breathe in this over-bloated state. Here is a calculator to see how it will affect you!…

I am so mad I am ready to blow, any one else care to comment on this mess?

admin answers:

I am so outraged that I spent the morning emailing the governator and our representatives in Sacto. I have been plaguing them with emails since this budget debaucle began, but this is the worst possible outcome! It really irritates me that they reached into the pockets of those of us who are still hanging on to our jobs and homes, but can barely keep ourselves from falling off the proverbial financial cliff. We have seen increases in food, electric, water, trash collection to the tune of 30-35% in the last year, losses of 35-40% in our home values, IRAs, 401ks and investment accounts and our wages have been stagnant or barely able to keep up with the increases in health care premiums or co-pays. In order to pay the increased personal income tax, we will have to save every dime of the $13 in federal stimulus and will still owe about $1300 to the state. In addition, the increase in vehicle license fees, sales taxes and other provisions will only serve to slow down purchases because consumers will tighten the purse strings even more. What burns me most is that they never even discusses suspending free services for the education, health care, social services or welfare to anchor babies of illegals. There is a huge sigh of relief in the illegal alien community that at least they will not be affected by the income tax increases while they still retain their free benefits while all of us taxpaying suckers get less government services and huge tax increases. Even my avatar is red faced with the passage of this budget! Did you notice, they basically snagged everything we could have gotten that might have benefitted us from the fed? We won’t be able to take advantage of purchasing energy efficient appliances, solar panels, wind generators, new cars and can’t even spend our stimulus because we will owe it to the state.

Not only cost effective, but profitable to the participants.
I am currently (no pun) building a wind turbine generator, for under $500. I had to buy a welder (got a deal) and if it works out, I’ll be building more of them, for sale.
If you have the proper type of electric meter outside your home, it will run backwards as you generate your own electricity, if you generate more than you use. Thus, you can actually make money doing this. If you end up with an electric vehicle and charge it at home…
You get the picture.
Here’s a search results page for this, called “Distributed Generation”——-

Check it out. They also have a 20 foot diameter version for greater output (more involved, more costly initially) that I may build later on.
I also have plans for a personal solar-trough type generator
that involves a closed-circuit water/steam system.

Betty asks…

How does a windmill work? For example, how does a homeowner get electricity from the windmill to the home?

Are wires connected from the windmill to the home?

admin answers:

Wires are usually connected to a battery pack that is connected to the home. That way if the wind is blowing at night when you are not using electricity, you will have it in the morning. This is especially true of solar panels. They sometimes add a generator here. In many states, people sell their excess energy back to the utility company. The meter on your house actually spins backwards.

Your Questions About Wind Turbine Syndrome

Robert asks…

If everyhome in America had a wind turbine mounted on the roof how much energy would we save?

I don’t care if you believe in global warming or not, I think in America we have the spoiled brat syndrome. Both Cons and Libs alike. While I used to think the oil company hack politicians who are mostly GOP stood in the way, however even the most liberal senator on the hill sen Kennedy fought to keep out wind turbines from cape cod because his filthy rich 10+million dollar home owner said it would spoil the view.

the view, oil profits and stupid voters are keeping us from at least moving towards energy indepedence.

Do you think we need to shed this extreme case of the stupids and build more wind turbines?

admin answers:

I do. Good case in point. Kennedy and his rich beutiful friends on cape cod are a prime example of the absurdity of our politicians and lack of a serious energy policy in this country. In CA i saw hundreds of turbines while flying to oakland last year. More are being built presently. But not here in the northeast- ted kennedy and company are hell bent on keeping us in the throws of oil dependency. They will not be happy till we have brown outs and hugo chavez is appointed dictator in the white house.

What are the best three electrical energy suppliers?

[Location no object] Can anyone give me the details of three electrical energy suppliers that offer the best value for money?

And any additional details about the company…(Website etc…)


admin answers:

Ecologically speaking

the Sun
Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used.

Solar power technologies provide electrical generation by means of heat engines or photovoltaics. Once converted its uses are only limited by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes.

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute sunlight. Active solar techniques include the use of photovoltaic panels, solar thermal collectors, with electrical or mechanical equipment, to convert sunlight into useful outputs. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines. At the end of 2008, worldwide nameplate capacity of wind-powered generators was 120.8 gigawatts.[1] Although wind produces only about 1.5% of worldwide electricity use,[1] it is growing rapidly, having doubled in the three years between 2005 and 2008. In several countries it has achieved relatively high levels of penetration, accounting for approximately 19% of electricity production in Denmark, 10% in Spain and Portugal, and 7% in Germany and the Republic of Ireland in 2008.

and Waves,(as in ocean waves)
Ocean waves are caused by the wind as it blows across the sea. Waves are a powerful source of energy.

The problem is that it’s not easy to harness this energy and convert it into electricity in large amounts. Thus, wave power stations are rare.


Today the largest use of hydropower is for the creation of hydroelectricity, which allows low cost energy to be used at long distances from the water source. Hydroelectricity is electricity generated by hydropower, i.e., the production of power through use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy. Once a hydroelectric complex is constructed, the project produces no direct waste, and has a considerably different output level of the greenhouse gas carbon dioxide (CO2) than fossil fuel powered energy plants. Worldwide, hydroelectricity supplied an estimated 715,000 MWe in 2005. This was approximately 19% of the world’s electricity (up from 16% in 2003), and accounted for over 63% of electricity from renewable sources.[1]

Some jurisdictions do not consider large hydro projects to be a sustainable energy source, due to the human, economic and environmental impacts of dam construction and maintenance.


Laura asks…

What is the difference between thermal and solar energy?

I know that solar energy is energy from the sun converted into elctrical energy and all that great stuff, but if you heat a sheet of flashing copper, put it in the sun and it makes a little more energy than it did in the shade, is that thermal or solar energy
OK I think the real question I’m asking is how is thermal energy converted into elctricity

admin answers:

Solar energy is energy from the sun.

There are many forms of energy.
– Plants use photosysthesis to convert solar energy into chemical energy.
– Solar cells convert solar energy into electricity.
– Evaporated and condensed water, thermals, and winds convert solar energy to mechanical energy.
– Copper flashing, like most things sitting out in the sun, convert solar energy to heat.

So, its solar energy until it is absorbed by the copper, then it is thermal energy (heat).

Edit: I know 2 ways to convert thermal energy to electrical. First is a thermoelectric generator. These tend to be costly, delicate, and have low efficiency. Check out the links below the article, especially the HZ-14 one:

2nd way is to use an engine or turbine. Concentrating sunlight with mirrors onto a small boiler creates high pressure steam. It is used in a turbine to make electricity. Some experimental units have actually been deployed by utility companies in sunny areas. While they depend on government subsidies, with enough emprovement, the technologies may stand on their own. You can also use solar energy to heat air or other working fluid inside an engine to convert the thermal energy to mechanical motion that drives an electrical generator. The most efficient such engine is called a carnot engine, which is unfortunately impractical to make economically.

Finally, things like windmills and waterpower actually convert solar to mechanical power, which is then used to drive generators. These are actually variations of the 2nd point.

BTW, if you’re asking how to make a simple solar cell from copper, see link:;_ylt=Apf5WS6KKGtoGDDSwRyFbIsAxgt.;_ylv=3?qid=20080520203652AAT6UzD

Your Questions About Wind Generators Alaska

Maria asks…

Is generating electricity by tidal power relatively cheap to run?

Physics related question.

admin answers:

You identified its strength – it is cheap to run. However, it is not cheap to build the facility. If it were cost effective to both build and run there would be lots of power plants.

Also, you need a bay to hold the water but around bays are usually cities and they are using the bay for commerce. If you find an unused bay, say in Alaska, you don’t have a population center nearby to use the electricity.

Also, just like wind and solar they don’t produce continuous power. You need a backup generator. If you are going to have to build a second generator why not just build only that generator.

James asks…

Any snowmobilers taking advantage of this storm? What do you do?

90% of people are hating this winter storm in the midwest and east coast, but how bout you snow lovers? I’m here in northwest indiana where we got a foot so far and just ecstatic about this weather. I’m just curious where other snowmobilers go or what they do to make it more fun.

admin answers:

Many years ago I lived in a communtiy where there were no cars – all winter travel was by snowmobile. In storms like this one we were always out checking on things, making sure everything was ok, sometimes fixing problems such as frozen water lines , helping sick or injured people get to the nursing station, and once we even had to help someone climb an electrical pole several times throughout the night because in the wind and blizzard wires would hit together and everytime they did a fuse blew and the whole communtiy would be without electricity – it was a huge deisel generator. He climbed the pole nine times that nght to change a fuse. Stuff like that doesn’t happen much anymore other than in places like Alaska and the Arctic in Canada. With all that said, I was very happy to wait out this storm in a tropical paradise. I don’t do winter anymore if I can help it.

My grandchildren and their parents who still live in a community where snowmobiles are in common use in winter go to their cabin for storms like this one – they ski, go ice fishing, snowshoe, make snow houses, and enjoy the simple life without electricity, away from the beaten path.

Your Questions About Wind Turbine Jobs

Mary asks…

Can sustainable technology (solar/wind) still be improved or does it just need to be implemented?

I am thinking about getting a major in Appropriate Technology, which is basically about sustainability and sustainable technologies like solar, wind, etc power. I’m curious though… how much can these systems be improved upon? I want to get into the engineering side of this field and be the guy who designs and improves them. I DO NOT want to be the guy who goes out and just installs solar panels all day. That’s not where my interests lie. Can a solar panel or wind turbine still be improved upon?

What are some other types of jobs I could get besides sustainability engineer or installer?

admin answers:

Hey Taylor, yes, I agree with the other respondents here, there are great breakthroughs to come in the renewable energy business. Let me outline some specifics: Solar panels today, or photovoltiacs to be exact, are only about 12 to 15 % efficient. Over 80% of the suns energy that hit them is only turned into heat, same as if it just hit the ground. They used to be 7%, but we have almost doubled that. The Germans are working on a project right now to harness the suns light and heat to convert to electricity, it is called Desertec. Their plan is to heat oil to over 600 degrees F, then store it in a huge building sized insulated tank. Then using water to oil heat exchangers, they can send water in which will boil in seconds and run a steam turbine. There are several advantages to this plan, not the least of which is the solar array is now 50 to 60 % efficient. A solar factory in the northwest corner of the Sahara Desert can power all of Europe, all day, and all night since the stored hot oil stays above 212 degrees well into the night. Now we have solar electricity even while it’s dark. This is experimental, but if it works that well, you’ll soon see these plants in desert environments all over the globe. Some items further out on the experimental table are liquid salt as a heat medium, and items like liquid nitrogen, and so on. There is plenty of solar energy in the world, we just need to get better at using it, and people like you can make that happen.

Looking at wind, Albert Betz was the scientist who penned what is now called the, “Betz Limit,” a theoretical limit on how much wind energy can be converted to usable torque by a turbine. You can check it out on google or wiki if you like, but in a nutshell, 59% is the maximum theoretical limit of any wind turbine. Well our best units today work in the 30 to 35 % range, well below the Betz Limit. Again, people like you can help us push that envelope out further, so now we can run all the homes in the Pacific Northwest on half the wind farm we would need using todays technology. The same can be said for biomass, landfill conversions, methane use, hydro power, and so on. The area of direct thermal conversion is really old school, even as cool as it is now. There is a woodstove you can buy today that when you feed wood into it and heat it up, it also makes electricity using a Peltier Heat Junction. They work, but are expensive and highly inefficient, again, a work in progress and probably years behind. Global warming is no wimp, just ask anyone on the East Coast USA what they think about it today after the last two “weather patterns,” they have been through. Or check out Sir David Attenborough’s comments on Yahoo’s front page today. K’s comment on fossil technology should be “fracking,” not “fracting,” but he’s correct, we seem to be finding more oil when we should be burning less of it. My feeling on that is if it’s unhealthy to pipe the exhaust from your car to the inside of the vehicle, it’s just as unhealthy to vent it to the outside too.

If you really have an interest in all of this, I highly recommend getting an education in the field and doing whatever you can, we still need more help working all this stuff out. Our home generates about 90% of its own electricity now, with the help of a solar array and small wind turbine. We heat with passive solar and wood, and collect rainwater as well as heat water with the sun, but life would be even better if all this could be done with less resources, less money, and more reliability, that’s where people like you could come in. Good luck Taylor, and take care, Rudydoo

Susan asks…

What electrical components need to be between the generator and inverter in a wind turbine?

For a school project my team is designing and building a wind turbine and, since I’m the only electrical engineering major on the team, I’ve been assigned to work figure out how to convert the rotational energy to electrical energy. The final output should be 120VAC with the ability to provide as much power and possible. We don’t know what the average rotational velocity at the generator will be. The team leader wants to use a DC generator that can produce a fair amount of power and low RPMs so they don’t have to make a gearbox. I’ve tried telling him that it should be an AC generator but I guess he doesn’t get it. I designed a diode rectifier bridge, filter capacitor, and Zener diode shunt regulator circuit to be placed between the output of the generator and the input of the inverter. This is the same basic power supply we learned 2 years ago from the same professor that has now rejected my design. Apparently he said the filter capacitor and/or regulator would waste too much energy. What should I do? Any and all help would be greatly appreciated.
The professor wrote something about the rectifer bridge being unnecessary with a DC generator, but I also wrote that it was being included in case the DC generator ends up running backwards or an AC generator is used. I think we need an AC generator because of the power loss over distance. Also, contrary to my wishes, we’re not charging batteries.

admin answers:

There are plenty of questions to be answered here…

Between the generator and the inverter, some sort of voltage regulation, including over voltage for over speed, and undervoltage. This may be included in the inverter, much as for solar panel inverters. Check out Maximum Power Point Controller. That may give you some ideas. The rectifier is often included in the inverter. Clearly the diode loss is reduced by going at higher voltages. In solar systems the inverter operates over an input range from 150 to 500V.

The problem with wind generators is that there is either too much wind or not enough, as well as the wind being “too bumpy”. Large scale generators have no choice but to go for efficient 2 or 3 blade fans, because the fan is already huge. Consequently they must be sited in “good wind areas”. They just start generating at 12 knots. A 2 MW generator may be around 50KW at 12 knots, and over speeds at around 28 knots from memory. The blades are 60m.

A smaller system is often in a less suitable location, and the multiblade fan suits better. This is more like traditional windmills on farms, sorted out during the 1800s. They work less efficiently but with slower winds, so you may get more out of them.

The mechanical guys see the gearbox as having high losses that cannot be solved, so the obvious solution is to hand that to the electrical guys. The electrical guy sees that the whole thing is too slow for normal generators. Car alternators for example are the reverse of what you want here. They are designed to go fast so charging works at idle speed. They may be up to 5000 RPM at idle. The generator needs to have a large diameter to work at low revs, which seems to be a problem that wind generators have, to me anyway. On the internet we see plenty of examples using car wheels as the frame of a home made rotor. In Australia the “Fisher and Paykel” washing machine motor is used. This is a multipole step motor, no gears in the washing machine. It may be adapted by rewinding sometimes. I am sure there are equivalents for any country.

The idea is to go for higher volts, considering you have an inverter. End of diode and commutator argument. Nevertheless some gearing may be necessary. You need some revs after all. How low can you go. Plenty of old time power stations worked with reasonably low revving alternators, usually 375 RPM, but I think there were some 187.5 RPM ones too. This is the electrical challenge – how to get good power and Volts at low RPM. Think about Faraday’s laws. Modern alternators are high speed, long and thin. You want a short fat one like a cart wheel. There is a trade off because this shape interferes with the wind. The advantage you have is the inverter. It is supposed to help, but it is a specialised one, like the solar ones.

In large scale wind generators, the rotor is rotated by the wind, and the field may also be rotated electrically. This helps with maintaining synchronous connections, but can also speed up the apparent rotation to some extent. They have variable speed gearboxes too, as well as blade control mainly for overspeed. No fooling around here. The all out approach. You could say the alternator itself is part of the inverter, part of the power regulation is attributed to the power gain of field to output power (about 10 times). Think about a rotating electro/magnetic mechanical amplifier. Do you want a field or rare earth magnets?

It seems to me there are always trade offs mechanical against electrical in such a system. Cooperation is needed in a team, but consensus is also not the best solution, though it is supposed to make everyone feel good.

Your Questions About Wind Generators Ebay

Chris asks…

Where can I buy a small generator?

I am making a very small scale model of the wind turbine for science class. I need to find a really small generator. Where I can buy that? If there isn’t one, if you know if any substitution for a device converting mechanical energy into electrical energy, please refer me to it. Thanks!

admin answers:

Depends, you can buy this in Ebay.-

Charles asks…

Has anyone made a home made generator?

Has anyone made a home made generator? I am looking to make a small solar, gas, battery powered generator, something that will run some barn lights. If you have made one, please give me a list of parts, and instructions. maybe a good website to visit.

How To Build A Wind Generator ———————-Build a generator from a lawn-edger motor.—————-Homemade generator—————————- home made generator Once I bought a petrol engine of an old lawnmower on Ibazar (now Ebay) because I wanted to learn how a four-stroke engine worked. I took it apart, cleaned everything, placed new seals and finally mounted everything back together. But she would not start. After having taken my tools again and having put it together a second time, around two weeks later, she gave her old sound again. It was the first time I saw her spinning, and she did great!

Having done all this, I thought, why should I not build something useful with this piece of beautiful equipment? At first, I had the idea of making a powerful water pump with her, but because I could not find suitable parts, I changed my mind and decided to build an homemade electric generator.

For making my electric generator, I started with the engine that I already had. It is a Briggs & Stratton 3.5 HP with a vertical shaft of 7/8 inch (22.22 mm) diameter. Serial number: Model 92908 Type 1282 – 01 Code 82021605 (engine is from 1982!) ——————-I made a homemade generator. Clip this post email this post what is this?

I recently built a homemade generator. I decided it would be nice to have if we lose power and I want to keep the refrigerator and freezer going.
Here is how I did it:

1) I asked around and got an old lawnmower given to me. It was a Murray with a 4.5 horse Briggs engine. The handle was shot, the wheels were falling off, but I got the engine running good. I cleaned the air filter, which I don’t think had ever been done, and changed the oil and sparkplug. It runs fine now.

2) I bought a steel plate for $25 from This plat has universal holes drilled for a lawnmower. It also has the mounting holes for the alternator I would need. I bolted the lawnmower engine to the plate. I took the blade off the lawnmower first though. I also used 3 washers between the plate and engine to lift it off the plate a bit. This was needed to insure it could get in “depth” alignment with the alternator, in other words so the shaft didn’t stick down to far.

Also, the blade acts as fly-wheel weight, which you lose when you take it off. I’ve found the pulley and alternator bring enough weight to make it work OK though and start easy enough.

3) I put a pulley on the lawnmower crankshaft. This to run the belt that goes to the alternator. I also got this pulley from epicenter. Theirs is a very good quality one, better than what I saw at Northern Tool.

4) I picked up a GM alternator. You can get the model number needed at theepicenter to from some of the plans they have. I used the alternator where you have a switch in the circuitry so that you can switch on the alternator to charge the battery, or you can switch it off. You can pick-up used alternators at the car junkyard, about $25. Or you can get a newly rebuilt one for about $50 or so. You do need to understand the different types and how they hook-up, which is really very simple. Theepicenter website gives a good description.

5) You have to bolt the alternator to the steel plate. I had to go to the hardware store to get the correct bolts and stuff for this. It was easily done though.

6) You have to get a belt to run between the engine pulley and the alternator pulley. I ended up getting one from theepicenter too, as it was about as cheap as anywhere else and I got the right belt. Read their info. To decide on the right belt to use. I put the belt on and tensioned it just by feel.

7) I had gotten some cables that would work to hook the alternator to the battery post of a 12V car battery that I had available to me. Tell the guys at the autopart store what you’re doing, they have them. You can also get them from theepicenter too. In this system you have to have a battery because a car alternator needs to be attached to one when it is charging. But that’s OK, I like having the battery because I can run small appliances without having to crank-up the engine.

8) Then I ran some wires and a couple of switches, which I got at the local auto parts store, to an inverter that I had ordered. I got a 1200 watt continuous inverter for $99 (and no shipping charge or tax!). You can get small 400 watt inverters for about $25 if you only need to power small stuff.

9) I didn’t mentioned that I built a wooden frame for this all to set on. Its a hodgepodge of 2×4’s I had laying around. But it does the job of holding the steel plate with engine and alternator, and battery

Your Questions About Wind Turbine Technician Salary

Steven asks…

Wind Technician Training?

Who offers training for an entry level wind technician or a wind technologist? What does a wind tech do or $ make? Please be as specific as possible with your reply because I am not looking for general information.

admin answers:

A wind tech is someone that works on wind turbines or has what can be called a windmill job. Wind technician jobs can range from construction to maintenance and repairs on wind turbines or windmills. Some sources on AWEA’s web site say that for every 10 wind turbines that are built, 1 new wind tech is needed for continual maintenance and repair. Reports of what they make vary. Some report a high hourly salary with a low per diem that can average around $65,000 per year in places with moderate costs of living while others report a medium salary with a high per diem that can total north of $75,000 a year. Many employers also carry employee health insurance and issue a company truck for work related duties. As with everything, compensation depends on demand from employers which appears to be high. For more information about job requirements and training do a search for California Wind Tech or go to because they have more detailed information than I can type in the space here.

Michael asks…

Wind energy technicians?

Wind Energy Techicians?

Would anyone advise going into this career? I’d like to hear from current wind techs. I am finishing up my degree in Politics, but have no desire to work in it–at least not right now–and would rather go into a trade or skilled labor. Do wind energy technicians make a decent salary? Money is not key. I’d like a career that is physical, stable and will make me a decent living. Also any info on job outlook will be helpful. Thanks!

admin answers:

A turbine technician combines working knowledge of mechanics, hydraulics, meteorology, composites, and computer science when servicing and maintaining large, commercial-scale turbines. Maintenance is conducted on-the-ground and at substantial heights, exceeding 200 feet. Technicians work in pairs for safety reasons.
