The friction in your bearings, your motor (or motors, whatever) has to be overcome to make your rig move once that friction is overcome the energy used to do it is lost and it is not possible to recover it with out some really tricky quantum physics that if you mess up will cause the universe to kerplode.

When I was in middle school I thought of a similar system of using generators to regain the power used by an electric motor propelling a car. Then I realized the drag from the generators would slow the car down, so I would need more power from the motor that was getting it's power from the generator, which in turn would make more braking action. So I thought of using the generators to slow the car down and the electric motor to speed it up and a small gas motor to make the car go along. Then I read about a hybrid vehicle and thought *******s beat me to it.

Learn from the mistakes of others, that way when you mess up you can do so in new and interesting ways.

One mile of road will take you one mile, one mile of runway can take you around the world.
