Have you guys seen this?

Dear Hans !

In german you call that "hydraulischer widder".
There are modern types to sell,
for example here: http://www.wasserpumpe-widder.ch/,
but you can find a lot if you look for "hydraulischer widder".
The power is taken from the flow of the main stream.
Nice, service friendly technology.

rgds.

Correct Fritz, but you cannot use it to pump water from a bore.

These pumps are used all over Australia for irrigation.

Its a water pump used on top of bore holes.
its powered by the sun.

It works a bit like a Sterling engine.
its made of plastic.
