Your Questions About Wind Turbine Generators How They Work
Daniel asks…
How to build or where to buy a wind turbine?
I need to build (or buy) a wind turbine that creates enough energy for a small LED light bulb. I used a small dc motor but it only creates between 0.056V and 0.087V. I need to build or buy one that works. I live in South Africa and all I saw were messed up prices for 500kw+ wind turbines. Time constraint till Friday. Please advise.

Best place to go for cheap is to go on YouTube and look up homemade wind turbines. Lots of guys use bicycle generators and car alternators and even make their own generators from magnets and coils of copper wire. They even show you how to make the propellers.
By the way, if you are only getting 0.087V from ANY dc motor, you might have a bad meter. I can get several volts from any DC motor just twisting the axle in my fingers, so something doesn’t sound right with your read there

How to build a wind turbine with cranks?
in physics class we have to build a generator to light an LED light, how do you build a wind turbine with a crank so i don’t have to blow wind at it?

Wouldn’t be a wind turbine then, would it??
