The world needs a new source of energy, an unspillable source.

Q&A: Is this a good idea for a wind powered car?

Question by joseph perez: Is this a good idea for a wind powered car?
I have an idea for a wind powered vehicle. Basically it has a battery like a normal electric vehicle and an electric motor. But when you go fast it opens up flaps that have wind turbines inside putting more energy back into the battery.would the tubines even produce enough energy? and is this even a good idea or has it already been thought of?

How would you generate power on windless days? You need somehow to STORE the energy. Producing energy is only one-half of the problem.
