Welcome to the Hypersonic Era
Hypersonic airliner to offer two hour flight from Paris to Tokyo
'Hypersonic' jet to travel from Paris to Tokyo in two-and-a-half hours - Telegraph
Plans will be unveiled tomorrow for a hypersonic airliner which will fly twice the speed of Concorde on biofuel made from seaweed, taking just over two hours to travel from Paris to Tokyo.
The EADS Zehra mach 4.5 hypersonic liner
If the futuristic plans for ZEHRA, standing for Zero Emission Hypersonic Transportation, prove feasible, the 3,125 mph jet will transport up to 100 passengers at more than four times the speed of sound, soaring 20 miles above the Earth – just outside its atmosphere.
At such speeds, it will take just 90 minutes to fly from Paris to New York, compared to three and a half hours for Concorde and almost eight hours in a normal passenger jet.
EADS, the European planemaker which is due to detail its plans at the Paris air show starting today, expects ZEHRA's first commercial flight to take place in 2050, with the first non-manned test flight slated for 2020.
Under blueprints leaked to Le Parisien newspaper yesterday, the jet will be almost totally environmentally "clean", forgoing kerosene in favour of a mixture of biofuel, hydrogen and water. Most of what little pollution it emits will remain in space.
It will target business passengers willing to pay the same price as a Concorde, namely around £5,000 pounds return from London to New York.

"Easy" Answer - Hydrogen & Oxygen Production
You use photovoltaic arrays to generate electricity to electrolyse Water or is it possible to heat water to a point where it dissociates into hydrogen & oxygen (I have just looked this up - Its seems a No no ) - Use of those vast solar arrays in Spain. Sunlight to super heated Steam driving generators. PS The electrolysis of Sea water seems to produce chlorine ? Any expert comments please ?
I'm unsure of the practical problems of electrolysis on an industrial scale.
Then HV DC Transmission to costal plants to electrolyse Sea water -( Chlorine does have industrial uses) . "The Future is a country about which we know very little."

I saw this and it just made me laugh. It's like the Paris airshow is being used for outrageous claims this time around.
I can't see any airline buying into an aircraft that is carrying multiple engines as dead weight for various stages of flight, with only the front 1/3rd of the aircraft taking passengers? Let alone the "Coming in 2050" tagline...I would have placed this annoucement at "Comic-con"
It would be better if the next 40 years were to be used to develop a more appropriate propulsion system for the idea.
I wonder if Boeing will rehash their sonic cruiser concept...
