| Nov 15, 2019 at 14:15 | comment | added | J... | To make a fuel cell work you need hydrogen and oxygen. 75% of the universe is hydrogen, but only 1% of the universe is oxygen. On Earth, oxygen makes up 46% of matter, most of it tied up in rocks, but hydrogen only 0.15%, mostly tied up in water...and rocks. How does that impact sustainability? Does it even matter? How do you propose to collect that hydrogen from the universe? | |
