Granted, the carbon }smoke LOOKS much worse (Heck, it's solid... isn't that a colloidal }suspension or something?), but it all falls to the ground eventually Conventional wisdom says so, but I believe recent studies in LA show that particulate matter is a heck of a lot more harmful to human health than the NOx, SOx, CO, and hydrocarbons that gasoline-powered engines put out. CO2 is of course not directly harmful to human health. Ask coal miners about breathing carbon dust... -- Matthew T. Russotto russotto@eng.umd.edu Some news readers expect "Disclaimer:" here.
