ROCKET that LITERALLY BURNS WATER as FUEL

It's an interesting fact that WATER is very dense and SAFE, and coupled up to an electolyser, to convert it back to hydrogen and oxygen - you have the perfect combustion based rocket fuel..

Then when you see the volume of space, that a Kg of liquid hydrogen would take up - it's HUGE.....

Quite the thing for deep space missions.... and refuelling in orbit, from the moon etc.. on the way too, on and back from Mars, Titan etc.

Everything has draw backs and advantages... Water, as a fuel source, makes a great deal of sense.

It also doubles up as really good radiation shielding.
