The future of commercial air travel is here, or will be in a few years. EADS, the European Aerospace giant, revealed its plans for a biofuel powered supersonic ‘rocket-plane’ that will take passengers from Paris to Tokyo (air distance of more than 12,000 miles or 19,500 km) in a mere 2.5 hours. That means it will fly at a hypersonic speed of 5000 km/hour (Sound travels at 1200 km/hour). The plane is, however, slated to be in operation only in 2050.
The capacity of the Zero Emission Hypersonic Transportation (Zehst) will be about 50 to 100 people. It will use engines fueled by biofuel made from sea-weed to take-off and will switch over to its rocket engines at high altitudes. The rocket fuel will be (nearly) pure hydrogen burning in oxygen, providing more bang for the weighty buck, while contributing no pollution whatsoever. The only exhaust will be water vapour
