Your Questions About Wind Turbine Generators Manufacturers
Maria asks…
Who is a manufacturer of a small generator that can fit inside of a small wind turbine?
Any help is very appreciated. I’m looking any manufacturer EXCEPT ones in China, which may be a kind of picky exception, hahaha.
Thank you

Try looking on www.thomasnet.com
Would an automotive alternator do ? THey would have the advantage that, being mass produced, they would be cheap. Also spare parts would be available through a huge supply chain, parts stocked on someone else’s inventory cost….
Steven asks…
How do you measure windmill efficiency without using a generator?
Is there a formula I can use to convert the number of the windmill’s rotations into watts or some other measurement? I’m doing a science fair project about windmills and I don’t have a generator I can use to measure the amount of electricity produced. The only formula I found is watts = (Kh x number of disk rotations x 3600) / number of seconds, but I don’t have the Kh.
I’m really confused, please help!

Go look at www.awea.org for general info on turbines.
Unless you know the specific turbine manufacturer and model, it will be very difficult to relate turbine speed (in rpm) to power produced.
Besides, how do you expect to relate rotational speed to efficiency?
Efficiency is Output electrical power divided by Input wind power.
Perhaps you should look at the capacity factor of wind turbines, and the resulting relative cost of electric power as it relates to capacity factor.
