There must be "something in the air" in Texas, lending itself to ultra
high efficiency electrolysis. This one is at .9 volts.

"AirGen’s technology has the potential to replace conventional water
electrolysis as the most prevalent method of hydrogen production not
reliant on fossil fuels as the feedstock. The foundation of the
patent-pending technology uniquely utilizes reactions catalyzed by
nano-sized colloidal metal particles. In testing, both thermal and
electrical energy sources have been used successfully to regenerate the
metal electrodes. This regeneration feature is an important benefit of
the technology and enables a closed loop system whereby the only
consumables are water and energy."
