...m.p.h.) and a range of up to 250 km (155 miles). Not so swift, you say? But this car is a clean machine: it gives off no pollution that could foul the air in any way. The E1 runs on an electric motor powered by high-energy sodium-sulfur batteries. Although it takes electricity to charge the batteries, the power plants can be far from smoggy cities...
...sell pollution "credits" to two other companies, among them one of the nation's dirtiest utilities, the Tennessee Valley Authority. This innovative, market-based deal, made possible under the 1990 Clean Air Act, will allow T.V.A. and the Duquesne Light Co. of Pittsburgh to spew larger quantities of sulfur dioxide into the air while WP&L reduces its emissions. The arrangement is probably the first of many, and it should help lower the overall cost of curbing acid rain, since some utilities may opt to buy less costly rights now and delay more expensive efforts to cut back pollution...
...Coast Air Quality Management District voted 8 to 1 last week to prepare an innovative plan that takes a market-based instead of regulatory approach toward cleaning up the dirtiest air in the nation. While the same concept will be tried under the federal Clean Air Act to reduce sulfur-dioxide emissions from electric power plants in the Midwest, California's Regional Clean Air Incentives Market program (RECLAIM) is the most ambitious attempt so far to cut urban air pollution. Under the plan, businesses will be issued shares in the region's overall emissions, and together they must reduce smog...
...blowup of 1991 rained volcanic ash on the Philippines and triggered massive mudslides. It also lofted 15 million to 20 million tons of sulfur dioxide high into the atmosphere, creating droplets of sulfuric acid that will reflect some of the sun's heat back into space. That could hold off global warming for a few years, but when the volcanic gas dissipates, The earth could make up for lost time and heat up uncomfortably fast...
Like the rocket car demonstration, many of the experiments feature the professors as the stars. Another, in which the professor inhales sulfur hexaflouride, transforms the professor's voice to that of Darth Vader's. Don't try this one at home...
