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
