   Yes, you really need some way to do it in a liquid, preferably a   
   reasonably pure one (the problem gets easier if the atomic hydrogen is   
   dissolved in a larger amount of ordinary LH2, but the performance is   
   greatly reduced).  Schemes using strong magnetic fields to help have been   
   suggested, but nothing has worked out very well.
