Hydrogen Engine: the future of aviation
October 25th, 2007 | by Gizmo |
Boeing has successfully completed tests for the engine that will power HALE, the extreme endurance plane that will be able to fly for seven days non-stop in the stratosphere. The wunderengine—developed by the Ford Motor Company—went for three days under the simulated conditions of a 65,000-feet flight, which is definitely better than a Taurus and apparently exceeded their expectations on fuel economy.
But, don’t expect this technology to hit a Dreamliner anytime soon
