energy concerns
enron weekend round-up
smog dogs
"Virginia environmental officials have hired a contractor to place two teams of technicians at different sites in Northern Virginia and Richmond beginning in March for a nine-month $300,000 pilot program. The teams, from Connecticut-based Environmental Systems Products, will set up at on-ramps and other high-traffic areas. They like to call their device the "AccuScan Remote Vehicle Emissions Testing System," though some in the industry prefer the term "smog dog." The system shoots an invisible beam of light through a car's exhaust plume to measure a range of pollutants, and a video camera records license plate numbers. Computers in a van parked nearby crunch the emissions data."
