The aviation industry may one day be powered by algae. Manufacturing giant Boeing says that a biodiesel alternative made from algae could be the aircraft biofuel of the future.
Last month, in an 8-page document plainly titled "Alternative Fuels for Commercial Aircraft", Boeing presented their estimation of the alternative fuel sources that could 'relieve worldwide pressure on crude-oil derived fuels' and drive air travel to carbon neutrality.
The biofuel debate has largely glossed over the 'friendly skies' while high fuel prices continue to take their toll on the industry. No biofuel we have yet can step up to the plate. Ethanol collects water and corrodes the engine and lines while biodiesel freezes up in cold weather (ie: cruising altitude). Don't forget pilots' general resistance to change and a life and death dependency on reliable fuel, and aviation biofuels don't have a leg to stand on.
