Have you guys seen this?

He mentions the vaccuum effect in the first page - the gravity thing was obviously tongue-in-cheek...

Hi hansvonlieven

A friend of mine, is asking about a device called a billabong pump,a solar
water pump,normaly used on top of bore holes.
any info on this

thanks

By adding a radiator to the vacuum chamber, this could be adapted to work as a quasi-"heat pump" motor, sort of like a stirling engine.  Better as a demonstration of simple thermodynamics than as a free energy device.  Although it works on slightly different principles, this system reminds me of the old "ammonia fountain" demo from the Mr. Wizard era of kid science experiments.  In that one, the vacuum created by condensation of ammonia vapor at the top of the chamber pulls warmer ammonia solution from the bottom of the chamber through an inverted funnel.  As long as a temperature gradient is maintained between the top and bottom of the chamber, fluid will flow up through the funnel, creating a fountain effect.

There is a devise to get fresh water from salt water which uses a clear dome to catch the rising water droplets and then slide down the side to get drinkable water. It is called a solar still and it works.

Another way you might want to try is a solar activated sterling motor to help pump the water which maybe your billabong pump but I wouldn't put my stamp on it either.
