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?

I have an application where something like this would be a possible
solution.

Thanks in Advance

Wouldn't it be easier to buy a 12Vdc appliance and plug it into the cigar
lighter socket. There are huge amounts of things that have been specially
designed to run like that.



Typical vehicles may well have 6v electrics. I've not seen inverters
that work on 6v systems.
In anycase i want the mechanical effort off the road wheels to directly
drive a pump.
