WPI’s Ravindra Datta, professor, chemical engineering, is quoted in Mac News World on how the Department of Energy has developed an iPhone app designed to help drivers locate the nearest alternative fuel stations. The National Renewable Energy Laboratory unveiled the Alternative Fueling Station Locator on Thursday. Users can choose the alternative fuel they need, electricity, natural gas, biodiesel, E85, propane or hydrogen, and the app will display the 20 closest stations within a 30-mile radius, the article states. The decision to buy a car that runs on alternative fuel isn't one that many drivers in the U.S. are making, but the number is gradually growing, said Datta. "The switch to people looking for alternative fuels is a gradual process, but it is happening and this is incredibly useful information for the people that need it."
