There is an even simpler method. Just use ordinary DC electrolysis, where the oxygen and hydrogen are evolved at different electrodes, resulting in a complete separation from the start. Hi Robin Yes, of course that would work - but most of the participants in this H-Cat thing already have the multi-plate HHO cells, which cannot be easily modified to do what you suggest. My aim was to come with a simple fix that might allow them to see Ni-H gain with what they already have in operation. BTW this guy on YT has an elaborate membrane system for separation: http://www.youtube.com/watch?v=IU6576HSrbc ...yet since complete separation is not required, a single membrane over the bubbler can do the job cheaply and quickly. If the HHO, which is normally a 2:1 ratio is partially separated into two streams, one of which is say 3:1 and the other is 1:1, then the extra hydrogen in the first stream is not only enriched but also thermally activated by the flame - which is the substitute for Rossi's resistance heat. This could allow the Ni-H reaction to proceed on the unoxidized fraction of hydrogen. Since the gain there is at least 6:1 according to Andrea Rossi, then the net efficiency which is seen now could jump from 77% well into the range of overunity... ... with the proviso "according to Andrea Rossi" ... which does not inspire universal confidence levels (but that may change in a couple of weeks). :-)
