Oh look, someone invented Cold Fusion (again)

All I'm saying is that anything that requires to consume stuff is going to be exploited until there's no more left. And I wasn't talking about hydrogen exactly, mainly everything else.

People laughed about petrol back in the day too.

Are you serious? The only one that could run out is nickel and we could just go to another rock and find more or just use another element to fuse with hydrogen (the one being made) and even that would take thousands of years if not more, also you can never compare hydrogen needed fusion to oil needed combustion mainly due to amount of energy it gives and its efficiency (which is around 90%+ while combustion at most is about 50%), in other words while a barrel of oil gives X amount of energy a barrel of hydrogen and nickel would give several times more energy.
