Lively bunch...

from the patent mentioned in #34 (that is simply an example of what is possible)

"The calculations were made assuming that part of MgH2 in a separate
tank would be reacted with water vapor and the high heat generated by the
reaction would be used to desorb the other part of MgH2 stored (in
another tank). The MgH2 in this other tank would actually be a
MgH2 --V composite and would work as a reversible metal hydride (in
this case, the reaction temperature should be at 573° K or above)."

So, without getting into the exact details of material science, there is a possibility of a reversable metal hydride. Granted some will be consumed, but what you are not getting is the H2 distribution network issue is solved with this technology. Before this announcement, the country would need a H2 filling station on every corner for the Hydrogen economy, now buying a few pounds of metal hydride will do the trick or whatever consumable the Genepax generator will need.

And no the energy is not in the hydride; it is in the chemical bonds within the water and the hydride.
Energy/mass is not created. So, what we look for in a new energy source is getting easy access to enough energy to do our work. I say a generator consuming water and some powder or whatever is far better than our current setup of sending Trillions of dollars outside the country to the oilmen.

Based on one patent, this technology appears to at least be possible, practial after much engineering work.

You guys need to read more carefully, ...
"This process is allegedly similar to the mechanism that produces hydrogen by a reaction of metal hydride and water."

Try this patent on for size. Word of interest: nanocrystalline

Very cool, ... my electric boat will never need refueling. You could drive in a rain storm without stopping... I wonder if you could suck water out of the air...say for planes...
