I was thinking, so you have your electric car it runs off electricity of course and normally from some type of battery, be it lead acid or hydrogen fuel cells. Now wouldn't it be interesting if it were possible to harness an electrostatic charge produced between your car and the road. The car after all is insulated from the ground with rubber tires, and we all know you sure can get a nice shock getting out of your vehicle.
I guess the question for the experts is, does this idea have any potential (no pun intended). Perhaps some kind of flat collector on the bottom of the car.
Just a thought.
