Pure-Gas.org provides a CC-licensed database, in the form of a Google Earth-compatible KML file, which contains a listing of gas stations that sell pure, ethanol-free gasoline. The list is maintained by users, who upload, update and remove stations using the website. The KML file has been incorporated into a free iPhone app and will be soon used in a free Android app. This is a great example of "cloudsourcing" of data. The database grows at a rate of about 400 stations per month in the summer, and around 150 stations per month in the winter.
