Fox...yeah, I think I had two semesters of thermodynamics..not my favorite course, but I did retain a bit.

I wish it weren't so, but those laws seem immutable.

I hope there are some deveopments in particle physics that may suggest new crystalline structures to enhance the capabilities of solar power. There is a tremendous amount of energy that falls on earth from the sun..as you know, we can only utilize a small portion of that in the very best solar arrays we now know how to build. I believe the improvements will need to come at the sub-atomic level. Regards.

OT - Fox, that is why Hydrogen powered cars which GM invented isn't flying. It's too expensive to split H20 and store Hydrogen into fuel cells, and can be dangerous. I believe the output from the car is water from the exhaust. Anyhow, unless we have an infinite supply of energy it's not feasible. May be nuclear energy needs to be looked into. But I guess that is why GM is on life support. While the Japanese decided to be more efficient and work on alternatives, GM went the other way after the 70s.

BTW - I just read an article today that said the lead Hybrid engineer for Toyota died as he was worked to death. He was only 45. His wife filed a lawsuit and it is the second lawsuit against toyota for "karoshi", japanese for worked to death.
