Hybrids are the buzzword now, and people marvel at how the latest Civic hybrid gets 50mpg.

Autoweek had a short article on the early Civics, which got 55mpg with a carb. 1.2L, 50hp, 1500lbs. Sure, they were slow, but they were described as still being fun to drive. The way most people drive modern Civics, I doubt they'd notice if they suddenly only had 50hp.

(yes, I know emissions are much better, it's quieter, it crashes better, yada, yada...)

Dr. A was a nuclear physicist, one of Dr. Teller's 12 disciples, and on the shuttle review board.  He always said they were gonna lose at least one shuttle. Burn one hydrogen with two oxygens produces..... water vapor... (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif) Ken Sounds good on paper. But wouldn't we be adding energy to the earth's atmosphere by doing this? The solar energy collected and then beamed to earth would be solar energy that would have missed the earth anyway. But by collecting it and then transporting it into our environment it has to go somewhere. Since energy can not be created or destroyed and we would be importing this energy from outside earth's own energy cycle, would not the end effect be further global warming and increased environmental damage?

It's controlled energy. I'm sure it would be ok, as long as the "exhaust" also finds it's way back into space.
