Hypersonic Passenger Jet Releases Water, Not Co2

Eco-friendly superplane could travel from London to Tokyo in only two hours.

The incredible new Zero Emission Hypersonic Transportation (ZEHST) was unveiled in blueprint plans at the Paris Air Show on June 20, 2011. Promising to fly virtually pollution-free at a speed of over 3,125 mph, the ZEHST will be powered mostly by seaweeds and a mixture composition of hydrogen and oxygen. Unlike traditional aircraft planes, the only emission the ZEHST will be releasing is perfectly harmless water.

Designed to be a successor of the legendary Concorde plane that became extinct in 2003 due to environmental and budget concerns, the ZEHST project has been headed by the European Aeronautic Defense and Space Company (EADS). Unlike its noisy predecessor, the ZEHST will be no louder than traditional airplanes.

Although this supersonic project is just a concept vehicle, David Kaminski-Morrow, air transport editor at Flight International stated, "It is well within capability. The technology is available. The real difficulty is the economics of making a completely new type of aircraft work. It will take billions to take it off the drawing board into the sky." The main concerns of experts seem to come from the economic limitations of creating the ZEHST. Having such a small capacity for passengers and a likely steep production cost could be deal breakers for this dream project.
