I'm kind of worried about the idea of taking drive off one axle. The diff.
is designed to transmit load to both axles at once, and I'm not sure it would
take kindly to having one axle fixed and the other spinning for long periods.
Never mind the thoughts on the rollers. However...

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.

That gave me an idea....

Caravans use 12v DC water pumps, some of them designed to work inline with
the pipe, others intended to fit at the dipped into the water end of the
pipe. Flow rates are enough for a shower, but lifting height will be
limited - say around two meters.

These days most car alternators produce a lot of amps - so an inverter
would be a cheaper solution. And more efficient. Most modern cars will
alter the idle speed to cope with the extra load.


Guys, this is a 2CV. Modern car? And aren't they 6 volts??

Andy.

Oh, OK...

Jack wheel up, remove wheel, fit a length of drive shaft bolted the
wheel studs - driving an Archemedes screw pump Þ
