Years ago, there was a prototype electrical generator shown on TV -
possibly Tomorrow's World etc.

It was a low ramp on which one wheel of a vehicle was driven and
parked. In the ramp was a pair of rollers driving a generator. The
other vehicle wheels were chocked. With the car in gear and at
tickover speeds a useful amount of power was generated.
I seem to recall the demonstration was a farmer going out to repair a
gateway and being able to run an electric drill to assist the repair.

Does anyone know if this was ever taken to a commercial product and
have any references to it?

Sounds like an extremly simple & practical idea - along the lines of the
wind up radio. Possibilities are endless, hook up a hydralic pump instead
of an alternator & the world is your lobster.

I wonder why it never made it? Prolly too simple & practical. Most of the
Third World would love the idea.
