This is neat.  How many times more powerful than venting steam out a nozzle?

Very interesting concept!  Probably not much in the way of thrust, but the
amount of "fuel" that can be created from a little water is pretty large,
and we have lots of time.  

But, tell me, in zero gravity, how is the gas separated from the water?  On
Earth is just floats to the top, but that doesn't work in outer space.  Is
the whole thing spun?
