Your Questions About Wind Generators

Lisa asks…

Can you use a car alternator to build a wind generator?

I am very interested in trying to build my own small wind generator, I seen that you basically need a alternator, blades to build the fan, cabling and a battery. So could you use a car alternator and also how many 12V batterys would you need?
I think that was a little rude, judging by what you posted you seem to be a all around d*ck!

But thanks to the others who replied, you info was very helpful. thanks again.

admin answers:

You may have better success with an alternator with the field coils replaced with permanent magnets and the regulator removed. This will maximize the voltage output and allow you to regulate the voltage at the battery bank. The less electronics and other items to break up the tower the more reliable the system will be.

You should use deep cycle batteries, not automotive starting batteries. The number of batteries will depend upon the voltage your system operates, power capacity of the generator, and size of inverters. Do not go overboard with too many batteries or the generator will never be able to fully charge them.

There is someone near me who is building the blades with PVC pipe. He uses it to turn a permanent magnet DC motor to act as the generator. I’ll try to find his web page later.

I’m hoping to get back to my wind generator project shortly. It’s been tied up in municipal bylaws and idiotic permits…

How to build a wind generator for a sailboat?

Does anyone have good plans for a small 24″ three blade wind generator ?

admin answers:

Hi,

You can try this set of plans :

http://www.agua-luna.com/wind_gene.html

But it will be good if you spray a protecting coating on it for make it marine grade.

The following steps were taking directly out of that DIY guide I offer to those who would like to run their homes on wind power safely, reducing their monthly utility bills or even selling power back the electrical companies.

“This manual is based on using a 260 VDC, 5 A continuous duty Treadmill Motor with a 6 inch threaded hub. These motors are available for under $50 from most motor surplus stores. We are getting about 7 amps in a 30 mph wind. In other words, it is a simple, cheap little machine to get you started. ”

“ASSEMBLY
1.Place the motor on top of the square tubing & bolt it in, using the two 5/16” x ¾” bolts.
2.Place the diode on the square tubing, about 2” behind the motor, & screw it into position using the self-tapping metal screw.
3.Connect the black wire coming out of the motor to the positive incoming terminal of the diode (Labeled AC on the positive side).
4.Connect the red wire coming out of the motor to the negative incoming terminal of the diode (Labeled AC on the negative side).
5.Center the tail over the square tubing, at the back end. Clamp your tail onto the side of the square tubing.
6.Using 2 self-tapping screws, screw the tail in place.
7.Place each blade on the hub so that all the holes line up. Using the ¼” bolts & washers, bolt the blades to the hub. For the inner three holes, use two washers per bolt, one on each side of the blade. For the outer three holes, just use one washer next to the head of the bolt. Tighten.
8.Hold the end of the shaft of the motor (which comes through the hub) firmly with pliers, & turn the hub counterclockwise until it tightens & stops.
9.Screw the nipple tightly into the floor flange using a pipe wrench.
10.Clamp the nipple in a vice so that the floor flange is facing up & level.
11.Place the square tubing (and everything that is on it) on top of the floor flange & move it so that it is perfectly balanced.
12.Through the holes of the floor flange, mark the square tubing at the point of balance.
13.Drill these two holes using a 5/32″ drill bit. You will probably have to take off the hub & tail to do this).
14.Attach the square tubing to the floor flange with two sheet metal screws.
For a longer life span of your wind generator, you should paint the blades, motor sleeve, mount & tail.”

Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at www agua-luna com on the subject. I also offer online & on-site workshops, seminars & internships to help others help the environment.

Your Questions About Wind Turbine

David asks…

How to model wind turbine blades on Solidworks?

Building a small wind turbine for a school project and was wondering how to model the turbine blades on Solidworks. I was intending to make the blades out of pipe to give the curvature already.

admin answers:

I’m not sure about using Solidworks unless that is a requirement of your course. But if it isn’t the blades are simple to fabricate without any special drawings. Small diameter turbines don’t have any problem with vibration, gyroscopic and centrifugal forces that large blades suffer from. But because of the small area that is swept and the quick radius turns of a small diameter, it is better to use multiple blades that almost fill the disc area similar to water pumping farm windmills. With a small windmill you don’t have much area to get the mill moving, so multiple blades ( 8 or so) increases the starting forces

Susan asks…

How long does it take a wind turbine to pay for itself?

Just an average size wind turbine in a wind farm.
Managed to find the answer myself, The average wind farm in the UK will pay back the energy used in its manufacture within six to eight months, this compares favourably with coal or nuclear power stations, which take about six months.

admin answers:

Hi

The payback period depends on so many things i.e. Cost of windmill, realisation per unit sale of electricity, mode of financing, location etc.

So people have different views. Variation is too large 3 to 8 years.

You may like to refer to following –

Nancy asks…

How might tidal energy be used in the future?

admin answers:

>
Tidal power can be used as a means of electricity generation achieved by capturing the energy contained in moving water mass due to tides. Two types of tidal energy can be extracted: kinetic energy of currents arising between ebbing and surging tides and potential energy from the difference in height (or head) between high and low tides. The former method – generating energy from tidal currents – is considered much more feasible today than building ocean-based dams or barrages, and many coastal sites worldwide are being examined for their suitability to produce tidal (current) energy.

The extraction of potential energy involves building a barrage and creating a tidal lagoon. The barrage traps a water level inside a basin. Head is created when the water level outside of the basin or lagoon changes relative to the water level inside. The head is used to drive turbines. In any design this leads to a decrease of tidal range inside the basin or lagoon, implying a reduced transfer of water between the basin and the sea. This reduced transfer of water accounts for the energy produced by the scheme.

Tidal power is classified as a renewable energy source, because tides are caused by the orbital mechanics of the solar system and are considered inexhaustible within a human timeframe. The root source of the energy comes from the slow deceleration of the Earth’s rotation. The Moon gains energy from this interaction and is slowly receding from the Earth. Tidal power has great potential for future power and electricity generation because of the total amount of energy contained in this rotation. Tidal power is reliably predictable (unlike wind energy and solar power).

The efficiency of tidal power generation in ocean dams largely depends on the amplitude of the tidal swell, which can be up to 10 m (33 ft) where the periodic tidal waves funnel into rivers and fjords. Amplitudes of up to 17 m (56 ft) occur for example in the Bay of Fundy, where tidal resonance amplifies the tidal waves.

As with wind power, selection of location is critical for a tidal power generator. The potential energy contained in a volume of water is

E = xMg
where x is the height of the tide, M is the mass of water and g is the acceleration due to gravity. Therefore, a tidal energy generator must be placed in a location with very high-amplitude tides. Suitable locations are found in the former USSR, USA, Canada, Australia, Korea, the UK and other countries (see below).

Several smaller tidal power plants have recently started generating electricity in Norway. They all exploit the strong periodic tidal currents in narrow fjords using sub-surface water turbines.

Your Questions About Wind Generators Indiana

Daniel asks…

Gas Saving ?

Ok! I’ve got a 94 Mercury Sable that is getting about 20/29 MPG. The Car is in really good shape Mechanically. Other than the fact that I need to pick up a New Radiator for it cause of a small crack on top of the Radiator. Which I keep an eye on how much Antifreeze is in there. Until I can throw a New Radiator in. But, Basically would it be better to put a bunch of Gas Saving Stuff into it or Just go get a New Vehicle that gets a higher MPG? Gas is $3.95 in my area of Indiana.

admin answers:

You won’t get much money for your car, and it would take an awfully long time to recoup what you spend on a new car, by getting better fuel mileage. You can hypermile that Sable and get even better mileage, and drive it forever.

Tom and Ray Magliozzi (Click and Clack, the Tappet Brothers on NPR’s “Car Talk”) will tell you that the money-smartest thing to do is to buy a car and drive it until it disintegrates from old age. Then start over. So don’t buy a new car, just fix this one.

There are no “gas-saving” products that work. It’s all BOGUS – you’ll mess up sensors, or clog fuel filters, or something. So skip the vortex generators and the “engine re-plating” pills that go into the tank, all that junk. ‘Cause that’s all it is, junk. DO, however, run the occasional bottle of fuel injector cleaner through your tank. It helps, it works, and it can improve your mileage.

GAS-SAVING TIPS: keep up with the oil changes. Switch to full-synthetic Mobil 1 or Castrol Synthetic – it makes a difference.

Check and/or change the automatic transmission fluid in your tranny. Have this done AT THE DEALER – quickie joints may not have the right additives in their one-size-fits-all fluid for your tranny. That’d be bad. We want you to be happy with your car for a long, long time.

TIRES: pump them up to the maximum printed on the tire’s sidewall. Ignore the manufacturer’s recommendations that’re on that little plate inside the driver’s door – Ford recommended way too little for the Explorer and look where all those folks wound up – upside down! Top ’em up. Keep them topped.

INSIDE: crash diet. How much junk is riding around in your car that you don’t need? There should be the basics: quart of oil, spare tire, jack. Fire extinguisher and flares, first-aid kit. Everything else is optional. Every ounce you drag around that doesn’t need to go somewhere, you’re burning fuel to give it a free ride. How smart is that?

ROOF RACK: take it off. Just the crossbars. Unless you’re taking your mountain bike with you everywhere you go, that thing is inducing turbulence up for no reason. If you never rooftop anything, you’ll never miss it. If you ARE taking your bike places, get a hitch-mount carrier and put the drag-inducing bike in your slipstream.

SLOW DOWN: Leave for work fives minutes earlier and ease off the gas. 5mph on the road at highway speeds makes a huge difference. Astonishing, really. Have a tendency to creep back up? Use the cruise control. Then all you have to worry about is maintaining safe spacing and when to exit the freeway. Learn to ignore the frustrated people behind you. They should’ve left earlier, if they have to speed to get somewhere on time. No cruise control? Get one aftermarket and install it yourself. It isn’t hard: I’ve done two, both times for improved fuel economy.

ADJUST THE NUT BEHIND THE WHEEL: (hint: that’s you) Your driving habits make all the difference. The only thing I’ve changed on my truck is the tire pressure, but all my habits are completely different. The EPA says my truck should get 22mpg on average, I’m getting 34. You can do it too. It’s called hypermiling, and it’s easy. Go to Ecomodder.com, or CleanMPG.com for more ideas.

NOTE: early research suggests hypermilers get fewer accidents, and their cars tend to last longer, due to their increased habit of situational awareness and gentler driving practices.

Michael asks…

What are the reasons for the Amish community in America living like people did hundreds of years ago?

I picked up an internet buzz that people are living without electricity and in really old fashioned clothes. They don’t have cars and whenever there is a drive by shooting it’s like clip clop clip clop clip clop clip clop BANG BANG clip clop clip clop clip clop..

These people are religious and religion has something to do with how they live, apparently.

None of them are going to answer because they don’t have the internet but why do they live like this? Does anyone have any knowledge about them?

Serious answers only please.

GO!
@ Taz, don’t do that again or I’ll block you. I can’t be bothered to read through a wall of drivel, it just ruins the question.

admin answers:

I use to live near some Amish-man. I bought a 6 bedroom Amish house. There are many people who call themselves Plain People. I use to have a horse and wagon and no electricity so to speak. I did have and still do use a solar panel. Many Amish use solar. Some drive cars and some do not. It depends on what sect they are. The ones I lived by didn’t belong to any sect. They were too men living alone, father and son. The mother and daughter and brothers all moved to Indiana. These men made sorghum molasses, raised organic foods. Sold goats milk and honey. I too raised goats and made cheese. Riding along a flint covered road at night with the horses shoes causing sparks to fly in the full moon light is something I will never forget.
The Amish speak their own language. A mix of German and Pennsylvania Dutch.
They follow the Martin Luther doctrine.
The women and men dress modestly. Usually they each only have 3 sets of clothes. One for work, one for Sunday, and one extra. Married men have a beard and single men do not in most sects. The 2 Amishmen I lived by wore their beards long and they had mustaches.
There was a group of Amish named Swartz who owned a buggy shop. They sold kerosene, barn lamps and other useful items. They had a band saw attached to a treadle pedal. A bicycle was used to power a paint sprayer. They own wind generators. These people are self sufficient. And so was I. Compost toilets, water cisterns. Solar panels, green houses.
I could go on and on.

Ruth asks…

What do you call a structure that captures the wind and turns it into energy?

A. Windcatcher
B. Energy Blow
C. Windmill
D. Wind generator
E. Wind Sock

admin answers:

It is properly a “wind turbine.”

Vestas, GE, and Gamesa are the three largest manufacturers, and they all call them wind turbines.

A “wind catcher” would catch wind, but not use it to make electricity.
A Energy Blow isn’t describing anything.
A Windmill manufactures SOMETHING with wind–but it may not be electricity. (It might pump water, as in a Dutch Windmill.)
A ‘wind generator’ would make wind. (Think grandpa!)
A “wind sock” is used to determine only the direction of the wind.
