Unmanned hydrogen-powered aircraft in our future.

While liquid hydrogen as a fuel might have three times the energy content of hydrocarbon fuels per unit of weight, its density is one tenth of the hydrocarbons (0.07 vs. 0.7g/ml) - i.e. the energy content per unit of volume is 30% that of hydrocarbon fuels. Add to it bulky cryogenic storage tanks - and the spatial requirements of liquid hydrogen as a fuel become problematic, unless the amounts used are very large, like in space shuttle.

I like Hydrogen as a fuel. You combine it with other Hydrogen atoms to make Helium.
Oh wait. the greenies don't like that method.

It's a simple question of weight ratios. A 5 oz aluminum bird can't carry a 2 pound hydrogen coconut.
