A biofuel for planes made from animal dungAerospace - From 10 to 16 July
After buses and cars, planes are also turning to biofuels. This summer the commercial airline United Airlines will be launching an aircraft equipped with hybrid engines, 30% of which will be powered by a biofuel made from animal feces. The first flight will be between Los Angeles and San Francisco. If the test is successful, four out of five flights will use this new propulsion system from September. The company believes in biofuels: it has just invested $30 million in Fulcrum BioEnergy, a company specializing in the production of biofuels for planes.
