Your Questions About Wind Turbine Jobs
Betty asks…
is it possible for people to operate wind turbines almost like peddle bikes?
what i am saying is to make a smaller power generating wind turbine and replace the propellers with a bike…..if this was possible how much power/jobs could this open up?
admin answers:
Hey Bret, Blamay is quite right. We’re assuming you ultimately want to generater electricity by peddeling something, is that correct? Some years ago we built one ourselves using a car alternator. Turns out that just would never work. A car alternator is horribly inefficient, needs to be continuously excited by battery power to generate a magnetic field, and once it is up to speed, it creates huge drag on what little torque a human can bear to get the battery voltage up to where it needs to be. What works much better is an electric scooter motor, inexpensive, permanent magnets, ball bearing movement and lower RPM requirements.
Check out the website below, they make a stand you can strap your bike into, the wheel turns the shaft of a small scooter motor/generator while you peddle. The faster you peddle, the more power you generate.
What you have to understand is that a healthy human being exerting around 75% power is only putting out about 1/4 to 1/3 horsepower. Even in a perfect world, that only equates to about 170 watts. Most people aren’t going to do that for more than 20 or 30 minutes a day, so if you do the math, you’re much farther ahead just purchasing a small 50 watt solar panel and letting it do the work for you, and you don’t need space in the garage to run it. I still think it’s a great idea, that’s why we have one here. Sometimes I’ll pay the kids a nickle to peddle it for 15 minutes if it’s cloudy out for a few days, but you’ll never make a “Ton” of power with even a thousand of these things, they are more a novelty, useful for education and games mainly. If you really want to learn more about renewable energy, check out some of the sites I’ve included below, or click on my avatar and check out some other questions and answers we have done recently. Take care Bret, Rudydoo
Jenny asks…
What type of engineers work in the field of sustainable energy?
Im considering doing a Building Services and Sustainable Engineering degree, what kind of jobs do you think it will open up for me?
Will i be able to work with sustainable/renewable energies, such as solar panels, wind turbines etc? or would i need a different type of engineering course to do that?
Any more information on engineering would be more than helpfull, im not 100% sure whether i want to do an engineering degree or not.
thanks
admin answers:
Hi,
From my own knowledge, jobs open for Sustainable Engineering degree are Electrical Engineer, Project Engineer, Project Admin., Project Manager etc.
Some consultancies provide solar installation courses, but I am not sure if it is what you want to do.
And sustainable engineering is a vast concept, you may need to choose your major orientation later, like wind energy, bioenergy, or solar…

Michael asks…
Please can you explain why the output voltage of a wind turbine generator is proportional to the angular speed?
Please can you explain why the output voltage of a wind turbine generator is linearly proportional to the angular speed of the rotor based on Faraday’s induction law and the definition of magnetic flux?
Please help me i cant find it anywhere
admin answers:
Faraday’s Law states that the voltage produced in a coil, moving relative to a magnetic field, is directly proportional to the number of turns in the coil times the change in magnetic flux per unit time.
V = -n (dB/dt)
In a rotating machine, obviously the number of turns in the coil is a constant. Also, the magnetic field in permanent magnet generators can be considered a constant for this purpose.
What changes when a wind turbine rotor speeds up (or slows down) is the rate of change of magnetic flux per unit time. When the rotor speeds up, the dt in the denominator becomes smaller (it takes less time for the rotor to move a fixed angle). Therefore, the voltage must increase as the speed increases. Conversely, as the rotor slows down, it takes more time for the rotor to move a some fixed angle and the dt in the denominator becomes larger, causing the voltage to drop. If the rotor is stationary then it effectively takes an infinite amount of time for the rotor to move a given angle. If dt becomes infinity, obviously, V becomes zero.
For the pedants out there:
I am aware that I played a little loose with dt vs. Delta t, but for the purposes here I think it illustrates the point well enough

Beat you to it I’m OFF THE MONEY HUNGRY GRID. Ive been building solar panels from old broken cells i get off eBay allot cheaper then buying them and they are working really well . Takes a Little time imagination and work but well worth it. I have a few pics in my blog showing how i do it
I have a flat roof on my house and im building a low level wind mill my own design with the power shaft going through the roof going into the second story room that i use for my power room and that i use for my lab . The generator will be inside of the house . Its a 12 volt permanent magnet generator that came off a john dear tractor . I was going to use a GM alternator but they need to turn faster to produce electricity . The neighborhood thinks I’m the nutty professor but hey nothing like living free and i sure don’t worry about the power company shutting off my power .
Tell you the truth its just been a lot of fun building my own system.

Wind Generators.Does the AC generators for sale on ebay need a battery(exicter) to help them create voltage? I?
Does the AC generators for sale on ebay need a battery(exicter) to help them create voltage? I have a DC generator & it produces voltage without a battery. It will produce about 15 volts by spinning the shaft by hand. Just curious about the AC generator. Thanks.
admin answers:
It depends on the make and model
it is a design criterion
if there are permanent magnets, it will self start, the output control becomes more difficult
if it has only an electromagnet like an automobile alternator then it is much easier to control the output

What would you do if society colapsed end every one was on their own?
no cooperation between anyone, not even families
no utilities or power, unless you can provide it for yourself like your own well or generator and if you can you have to protect it from any one else who might want to steal it for them selves.
no sale or trade between people you just have what you own and what you can take or steal from others.

Your Questions About Wind Turbine Technician Jobs
Sharon asks…
Is it too inconvenient for a wind turbine technician to live in a residential area and not the country?
Im very interested in a career as a wind turbine technician but I have no idea where the average worker resides. I like the country but do not want to live the country life. I’m more of a city person. I like the commotion. My major concern is I want to live in a residential/suburban neighborhood but still be generally close to my job.
admin answers:
My husband has been a wind turbine technician for around a year. We live in California. The wind turbines that I know of in the Mojave desert are NOT near an urban area, and you would be living in the desert while working. There are wind farms close to San Francisco, though, and you could probably live somewhat close to the work site. But a lot of wind turbine technicians travel. For example, right now my husband is working in Illinois, and he has been there for five months. It is in a rural area, but the city is within an hour drive. 🙂 I don’t know if that helps.
Ken asks…
How do you become a Wind Turbine Technician?
What do i need to learn ? My background is in Electrical & Electronic Engineering,but i am unemployed at the moment and want to take steps in the direction to become a Wind Turbine Technician.
admin answers:
Very limited field.
Congrats on your initiative. Good research efforts.
Complete thorough realistic research to achieve life sustaining income. Maybe accounting, engineering, law, medicine, computers, …. Always get real job descriptions with course requirements from employers, unions, certification groups/associations. Don’t sign up for education till you’ve done this, EVER!!!
Pick a path where you don’t start working bankrupt with debt. Don’t become another casualty of the Trillion$ student debt. You must earn enough, $200k+ to support a family in a major City. Do not low ball your life and your family. If you can’t find work volunteer to get in the door. Try volunteering at good potential employers and go down from there to community service, but get in anywhere and start working/networking, even if its for free.Be a model worker, no yapping, internet, cell phone..start work 30 minutes early and end work 30 minutes after day’s end. Keep learning from more courses, read books, get another language, etc
There are almost 50 million people on food stamps, ~20% of males 25 to 54 yrs not working, lowest SATs in 40 years, debt to GDP over 100%, 25% of global prison inmates with only 5% of global population, etc and whats uncle sams answer to America’s problems? Corrupt political paralysis and meteroic debt plague spiking by adding a trillion dollars of debt in 2013 to criminally prop up financial markets artificially. What a mess we live in!
You are On Your Own. YOYO’s the word. Never forget it. Take control of your own lives and ignore what ever fictonal solutions the politicians and corporate bobble heads throw around as their self-profiteering benevolence.
Abandon obese consumer spending debt addiction culture and resulting self enslavement. Cut your lifestyle in half or less of the destructive unrealistic American dream nightmare standard….small house or apt..one car or no car .. Always have a second job cause the one you have can/will disappear …save and invest over 50% of your income if you can …. Stay with your parents….parents move in with your kids…Rent with friends…rent rooms in your home ..Live like the wage you make today could be the last you’ll earn, always. Stay away from ponzis, addictions, unhealthy lifestyles, get rich scams, online rip offs and purple koolaid cults.
Most of all maintain constructive positive relationships and forward planning. Have fun at it without spending money. What you are wanting to do is great but do it with a strong dose of reality and caring for your future, family and community. Good luck! Cheers:).

Your Questions About Wind Turbine Generators Types
Paul asks…
How does a wind turbine generate electricity?
im making a diagram upon how wind turbines generate electricty
so please help me to like create. i know the wind turns the blades which creates electricity via the generatore. but how does it occur.
what type of energy is used. EG kinetic, thermal?
/thank you xxx
admin answers:
A wind turbine is a rotary device that extracts energy from the wind. If the mechanical energy is used directly by machinery, such as for pumping water, cutting lumber or grinding stones, the machine is called a windmill. If the mechanical energy is instead converted to electricity, the machine is called a wind generator, wind turbine, wind turbine generator (WTG), wind power unit (WPU), wind energy converter (WEC), or aerogenerator.

What can you tell me about wind turbines that move vertically or in a helix shape?

Links, videos, and any other information is greatly appreciated as well as your general imput. Thanks!
Overall, do you think this would be an investment or a waste of money. (We would receive grants, fund raise, etc…)
admin answers:
Kinda depends…. Are you getting a contractor to show-up and install it, or is the project being done by locals? That is who is responsible for design, fabrication, installation?
If this is to produce electricity, are the generators a direct to grid design or will there be inverters?
Send me individual email, I’ll discuss this with you, if you are interested…
Given “grant $” this could be a win-win, HOWEVER, has anyone checked on the MTBF figures for the sort of wind plant that you intend to install? There are things that could make this a GREAT investment and there are factors that could end up costing your town a LOT of $ for no benefit at all.
I have no idea, how much or what sort of research has already been done. …. What?

Your Questions About Wind Generators For Boats
Linda asks…
Is there any safety issues in using a non marine grade generator on a boat?
The difference between a marine grade 5kw generator and a common home or job site use 5 kw generator is thousands of dollars. I understand salt being an issue but I am on freshwater. As long as I am not spilling fuel are there any safety concerns?
admin answers:
You have more then exhaust fumes to worry about. If the generator has its own gas tank it will be vented into the boat (if you have it in the boat). Getting enough air to cool it would be a problem and how would you get the exhaust out. You could try it on the back of the boat but if there is any wind you have to worry about the station wagon effect, wind swirling around and pulling fumes into the boat. Not to mention it getting wet if a wake hits you from the back. I don’t think you would do to well if you got boarded by the police or the USCG as that is not an “approved device” How about putting in an inverter and a dedicated battery for 110 volts instead?
Carol asks…
Will a trolling motor generate electricity and charge a battery if it is pulled thru the water?
Specific application I’m looking at is using a high thrust trolling motor on a small sailboat for the auxiliary propulsion. Research indicates this will work great. However, the various sites advise using solar/wind/ or shore power for recharging.
Suppose the motor was left down, we raised the sail, and the prop began to freewheel. Seeing as how this is a DC motor, wouldn’t it start generating electricity? Has anyone tried this? What type of controlling circuitry would be needed if any to charge the house batteries?
admin answers:
Here is the Biggest problem with the trolling motor generator…Its not with the motor but with the capture area of the prop…Lets do the math here real quick …I promise not to take to long…If your trolling motor uses 10 amps at 12 volts thats about 120watts …756watts is about one horsepower,……. To get enough drag surface on the prop you need about 60 sq inches….120/756=.16hp or 480 sq inches per hp….more or less..so thats a pretty good size prop lets say 5″ x 12″ now to get it to spin you need a very easy rotating motor/gen set if its a permanent magnet type you have a problem getting it past the first pole is pretty hard…now lets look at rpm for a moment normally your motor cranks out that 120 watts at say 500-600 rpm to get a sail surface relationship and pitch to get your 12 vdc back… Your gonna need to have one heck of a pitch or loose your voltage for lack of rpm.. So I would say this …your idea of using the regenerative power of a dc motor to make a little wattage is quite sound ..However using a trolling motor made to puLL your boat might not be as efficient as some other means…Keep working on the idea though try using a right angle gearbox being driven by a floating paddle wheel ..or perhaps a flexible driveshaft underneath the boat with a helix coil driving an inboard alternator. Regulation for all the voltage is as easy as pie… A couple of big caps and one transistor and 30 minutes and you can build a regulator for nearly any thing up to 200watts…Ever hear of the 12v Light bulb from the old days being used as a regulator? See didnt even need a cap for that one….Anyhow have a good day from the E…

Your Questions About Wind Turbines For Home Use
Donald asks…
Are wind turbines for the home beneficial?
I would like to learn more about the subject as I read not long ago that you can save money by installing wind turbines in your home. Are there any real benefits? Is it expensive?

Yes there are many benefits.
Using the wind to generate energy will permit you to be less dependent on fossil fuels, which are non renewable. So you will actually be helping our environment.
Also, there is the economic factor, you will save hundreds each month in electricity.
If you are going to buy a wind turbine for the home, be prepared, because they are costly. A solution for this would be to build the wind turbine yourself. Here I provide you with a link that has more information about that subject.
