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.


Despite all the naysayers I still reckon this idea has legs. Average small
car must develop 50hp +? Thats going to run a hell of a lot more than any
inverter ever could.


Not a 2CV.

AND certainly NOT running static with no airflow round the engine.

In the 1973 days we had a 2L cortina engine driving a 5Kw genny. (about
8bhp) it died and was replaced with a perkins Diesel. That managed it.

You need to derate a LOT for 24x7 static operation.
Definitely the easiest thing to do is too get a 6v brushed motor and
attach it to a pump and drop it down the hole and pump with that. Most
electric motors of that sort of voltage are fully capable of running
immersed in fresh water.

I dunno how much head they can pump against though,

The alternator should be capable of a few amps at least.
