Electric drivetrains are more efficient. That's why hybrids get better mileage even though they have a quarter-ton-plus more equipment. Also why diesel trains run generators and use electric motors. > that. Otherwise, the typical modern automobile engine is way > cleaner than the coal fired electric plant. I don't believe that at all. Even the nuclear plants have diesel backups, if it was really cleaner (= better efficiency) they'd be using them all the time. Coal scrubbers are pretty sophisticated, and if you are producing a lot of power in a single area you can afford much better filtration equipment than you can if you have a lot of small spots to clean. I think catalytic converters are a good idea, but I don't think it makes the exhaust anywhere close to what a modern coal plant outputs, much less nuclear. Diesel by that logic is out of the picture, I won't go there... Random geeks, via Google, seem to agree with my WAG, though not quite so overwhelmingly as I'd expected: http://forums.treehugger.com/viewtopic.php?t=1034 Only comparing CO2, a quick scan found a mention of other pollutants but it appears they are practically nothing after power generating. > Now if we could get some fusion plants online.... Agree, the more the merrier. Here in NC we still have a glut of capacity, if you need it bring cash. :) -Tim _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
