"Where’s the hydrogen coming from and how is it going to be produced?"

Exactly! I actually like this research. I see good uses for it. But the "problem" with energy today is political, not physical. In this case, the greenies of tomorrow would claim "oh my! We're using up all our hydrogen!" just as loudly as they claimed we were using up all our oil or whatever.

Our energy policies need political breakthroughs more than science breakthroughs.

As long as we have H2O, we will always have a source of hydrogen.

"We're using up all our hydrogen!" "

But slowing rising seas!

The earth is estimated to lose about 1,600 metric tons of hydrogen every year through natural means. It will take trillions of years for the earth to lose all its hydrogen, long after the sun burns out. Replacing all energy production with hydrogen fusion (at current rates) would require about 4 metric tons of hydrogen per year. Truly insignificant. For comparison, the mass of the earth is 5,972,000,000,000,000,000,000 metric tons
