Stirling Energy Systems creates electricity with these solar collectors. http://www.stirlingenergy.com/

Stirling engines are powered by the expansion of a gas when heated, followed by the compression of the gas when cooled. The Stirling engine contains a fixed amount of gas which is transferred back and forth between a "cold" and and a "hot" end. The "displacer piston" moves the gas between the two ends and the "power piston " changes the internal volume as the gas expands and contracts.

On September 27, 1816, Robert Stirling applied for a patent for his Economiser at the Chancery in Edinburgh, Scotland. By trade, Robert Stirling was actually a minister in the Church of Scotland and he continued to give services until he was eighty-six years old. But, in his spare time, he built heat engines in his home workshop. Lord Kelvin used one of the working models during some of his university classes.

Imagine if a pipe containing seawater were flowing into the focal point... The water would change into steam quickly... almost explosively... harness that change of volume with a steam engine... or a turbine...

they have landed a big contract to build a power station in southern California.

These solar collectors would be very practical in comparison to Atomic Poison Power... Did you know that the fellow who wrote the NO NUKES SONG, John Hall, is now in congress...

Solar Trough to focus sunlight on a pipe.

Lets suppose that you are pumping seawater through that pipe. Some of the water will boil and become steam. That could be collected and sold as pure H2O... the rest of the seawater will become extremely concentrated with the salt. At the end of the pipe where all this comes out, divert the salty water into ponds for evaporation. The steam would be billowing out the end of the pipe with some force. That force could be captured by turbines to create electricity... use the electricity to power the seawater pump.

A slight variation...

Disease-causing organisms in water are killed by exposure to heat in a process called pasteurization. Water that has been heated to 65ºC (150ºF) for a short period of time is free from microbes including Escherichia coli, Rotaviruses, Giardia and the Hepatitis A virus. At around 70ºC (160ºF), milk and other foods are pasteurized.
