Uh, I think this has more to do with the properties of Hydrogen as a coolent
gas rather than anything to do with the speed of sound.  I think the idea is
to blow the hydrogen through a hollow rotor where there are some engineering/
efficiency gains to be had from keeping things compact.  Where are all those
power engineers when you need them? 8-)
