Futurology

Ok, so uneducated, angry and easily offended. Happy to explain step by step but you need to check your attitude.

First of all, wind turbines are about 20-40% efficiency at turning wind energy into electric energy. So using an engine to create wind that then spins a turbine will only give you about 30% back - the rest is lost to drag, friction between gears an moving parts. Effectively, put a fan infront of a wind turbine and you lose three times the energy you get back. Put this in a car, the drag the turbine will produce spinning will use up 3 times the energy to keep the car moving compared to what you get. This drag from a spinning turbine is soo much that propeller planes have automatic systems in place that an engine failure won't make a plane uncontrollable by stopping the prop windmilling as much as possible. This doesn't matter for wind turbines as they 1, don't have to make themselves move, and 2, don't have to carry their own weight around.

In short, what you will get from doing this is drain the battery 3 times faster than you top it up. I.e pointless.

To answer your last point - yes, unlike you every engineer, scientist and designer in existence is too stupid to do this, patent their discovery and make billions in extending the range of EVs. That is the logical conclusion to take.
