Google has teamed up with the Environmental Defense Fund to detect leaks in gas lines in the Los Angeles Area, Boston, Indianapolis, Staten Island, Syracuse, and Burlington, Vermont. Google attached methane detectors to the cars it uses to create its street map images and has mapped the locations where it found levels of methane high enough to indicate pipeline methane leaks. A great use of new technology for a public purpose. View Google’s maps here. EDF has teamed up with industry and scientists to attack methane emissions, part of EDF’s efforts to combat global warming.
