I don't think the Casimir Effect is what is driving pistons! :-)

There is no gravity, the earth sucks!

I do think that reduction in pressure due to cooling works on Super-Critical Carbon Dioxide Opposing Piston Engines. Essentially super-hot brine enters the jacket and heats the SCC to expand and drive pistons apart, the rods only move back and forth, pumping hydraulic fluid (which in turn drives process), then at the end of the stroke (or nearly so), cold brine is passed through the cylinder jackets, thus causing the SCC to contract (parasitically using a small amount of hydraulic fluid pressure?). Rinse and repeat. The pistons are necessarily large, stroke is fairly long (as I understand it), and the only use for such an engine will ever be as a stationary device, but it works on solar brine pond, or waste heat, or geothermal heat.

I know one company that employs this technology, but I will not divulge their name here.

If energygod's goal was to cause a long thread, he/she succeeded! If the goal was a new source of energy . . . . Well, we'll just have to wait for prototype results.

To build alternative energy resources we have to use existing resources. So if we do not use present resources to build alternatives, and present day resources start to run out? What then??????? I have no problem with atomic power stations, and I also remember during my studies that American coal is high in sulphur?
