Peter - big Thank-you for using your text to speech; few minutes of time on your end saves several minutes of time multiplied by the number of readers at the other end. :-)

The Laws of Thermodynamics say you can't get energy for free- it takes energy to push a car, then you are using energy from the rolling car to charge a generator - just like the old dynamo generators on bicycle headlights (those of us old enough to have suffered them), it is hard work! If you have 100W of power, and your motor is 80% efficient, you'd get 80W at the wheels, connected to a generator which is say 80% efficient, you'd get 64W back - 36W in losses (noise, heat, etc). And that is without using any energy to move!

It's called 'regenerative braking'; the Shelby car I linked in the previous email uses it, as do many new hybrids and electric cars. Locomotives have used it for decades. But again, efficiencies and losses mean you are 'fighting a losing battle', but better than no recovery.

It will always be dangerous, for power results in the ability to heat and burn. But whether that is just risk from energy discharge, or the battery exploding, that can probably be better handled, depending on design and structures.

I believe Cold Fusion is science fiction, as it has never been shown to work. Bit like running a car on water (just ignore that giant battery working the system!!!).
Scrapper, Black Dragon, enamoured by the science of splitting water molecules, but dismayed by the efficiency of result.
