I was concerned at first that this would seal the final fate of the planet, but then I saw that it may meet the European targets for reduced CO2 output. Whew.

Major sigh of relief, after just looking out the window and seeing another polar bear at the bus stop. There\'s been a lot of them taking up all the hotel rooms in the area, and this news will probably cheer them up.

I\'ve been having all my enviro friends do their part by holding it in for 8 hours when they need to go to the bathroom, saving at least a flush per day. That water alone might show just one polar bear that we evil, horrible, greedy, capitalist Tea Party human beings are not all out to destroy them by our mere existence.

Can a jet engine be designed so that it can burn hydrogen?

Like ICE\'s Jet Engines can be designed to run on anything that burns. Just depends what you want

The Bristol Suntan was an Hydrogen engine test bed. It\'s on display at Raf Museum Cosford. They only built two or three and atleast one of them came down.

Like all \"zero pollution\" flights of fancy, all we need to do is find a hydrogen mine.

It\'d be great just to re-power standard aircraft to run on hydrogen.
How about just standard cars, for that matter!
I wonder what the projected costs for the whole program would be and what they would hope the ticket costs would be, in current financial measurement.

Griffin - June 21, 2011 @ 10:44 am PDT--- Were are you going to get the hydrogen?

Unlike other ideas, this seems to add up and makes a lot of sense. Less friction and once outside the atmosphere, noise will not be a problem, which poor old Concord had all the time.

You couldn\'t carry enough hydrogen to fuel the plane for flights longer than 3-4 hours..

Todd Dunning\'s simpering sarcasm comes straight out of the T Party. T stands for Texas Tea, OIL that is, Black Gold..he is probably permanently employed to mock, at every opportunity, anything that might undermine Texas Tea as the primary source of energy for the foreseeable future. If Todd is so sold on fossil fuels, let him start up his gasoline burning car in the garage with the doors closed and see how long he can \"hold it\". I\'m sure he\'ll find that what comes out of the tailpipe is only the sweet smell of money.
