From Water
Many technologies have been explored but it should be noted that as of 2007 "Thermal, thermochemical, biochemical and photochemical processes have so far not found industrial applications." High temperature electrolysis of alkaline solutions has been used for the industrial scale production of hydrogen (see Sable Chemicals) and there are now a number of small scale polymer electrolyte membrane (PEM) electrolysis units available commercially.

Famous quotes containing the word water:
“Instead of water we got here a draught of beer,... a lumberer’s drink, which would acclimate and naturalize a man at once,—which would make him see green, and, if he slept, dream that he heard the wind sough among the pines.”
—Henry David Thoreau (1817–1862)
“Eternal Venice sinking by degrees
Into the very water that she lights;”
—Edgar Bowers (b. 1924)
