STUDY * USA - Show promise for hybrid school buses
The hybrid-buses got 30% better mileage in Nevada and 36% better in Sigourney
Nevada,IA,USA -Radio Iowa, by Dar Danielson -March 29, 2010: -- Two hybrid-electric school buses were purchased for the Nevada and Sigourney school districts and run alongside regular buses... An Iowa State University researcher says a study of hybrid school buses shows some promise for decreasing fuel costs and pollution, if mechanical problems with the buses can be fixed. ... Shauna Hallmark of the I.S.U. Institute for Transportation, says the hybrid-buses got 30% better mileage in Nevada and 36% better in Sigourney. Hallmark says. Diesel fuel is occasionally up to $4.00-a-gallon, and a school bus gets about six miles to the gallon... Hallmark says it’s not just fuel economy, it’s also the emissions put out by the buses. She says buses put out a lot of the small fine black particulates that pollute the air, and the hybrid buses would reduce the amount of pollution the kids are exposed to... The charging system does some charging from the bus diesel engine, but the majority of the charging has to be done by plugging in the bus. And she says something was not working, so the batter did not charge... Labels: hybrid buses, studies
