i read a brief report about a cylinder windmill that when the wind isn't blowing, a motor comes on and gives power to the generator so it can continue making electricity. does anyone know more about this type of windmill? i can't find details online. thanks

The reason to have a motor turn the blades is so that when a gentle breeze does come up, the windmill can use it---starting the blades from a dead stop requires a lot of wind, so using a battery-powered generator makes the windmill capable of taking advantage of the first gentle breeze that comes up.

And where does that motor get its power? I hope you can understand that any generator being turned by a motor cannot generate more power than the motor that turns it uses. This is the old perpetual motion machine idea that has been absolutely, conclusively, totally and forever proved wrong.

If anyone was naive enough to make this windmill then they would use more energy to spin the windmill then they would be able to extract with the generator.

I don't see the point since you would be using more electricity to turn the blades than you would get back.
