Not really electronics, but...

I read an article somewhere about some MECHANICAL engineers who built
a car with some outrageously high efficiency. It seems that there was a
small gas motor which constantly ran at low power, to keep a hydraulic
container "charged" (i.e. pressurized). This energy was used when you
accellerated from a stop (where most of the energy was needed), then
reclaimed (in part) when you stopped (pressurized the tank again).
So it was like a wound-up rubber band, springing you forward...
