"I know some people will ask this question so here is the answer in advance! The wind generator is only for use when the vehicle is parked. The vehicle is not driven with the generator erected."

I do plan on powering my lights and other minor drains with a solar pack... not because it's efficient but because I have about 4 projects I want to play with and test.
Good find though.
