There are a bunch of existing technologies that can be used to improve gas mileage. This one has potential. Cars waste lots of energy, particularly while braking. New battery technology enables the recapture of some of this energy.

As always, when the technology becomes economically feasible, people will buy it. The people who perfect it will get rich.

I love capitalism.

I had this idea a long time ago, but I wanted to build it with superconducting electric motors in the in the wheel. I guess I will have to come up with another one now. BTW, the reason I never acted on this is because I didn't think it was a particularly original idea. I would love to seee if they even got a patent out of this application.
