Again, I was agreeing with you. The guy's proposal is groundless and 
impractical.
Whether the same could be said about hydrogen generation via PV power, 
That may be (and has been) subject to debate somewhere within this echo. 
Meanwhile, re-read the following:
 If you are using excess power from an existing PV array,or another RE 
 > source, you may not be losing anything in the effort. *If you add to 
the system to accomodate the hydro setup, or build an array specifically
for this app, the story could be different*
Putting that another way, If a hypothetical system is sized so that the 
system already has a significant excess of power (as a properly sized PV 
system would have once the batteries are fully charged), and the owner 
chooses to explore the possibilities of hydrogen generation, well, s/he 
already has the excess energy to play with. It might be far less practical 
to build an array solely for the purpose of hydrogen generation. I know a 
number of 'back to the land' folks who would do it even if it cost more, 
rather than continue to buy propane and truck it out to their remote home.
My personal interest is purely hypothetical at this time.
