Reply to comment by [deleted] in Rolls-Royce successfully tests hydrogen-powered jet engine by je97

That is highly misleading. Hydrogen in a form that can burn is not abundant. You have to put more energy in to separate hydrogen from things like water than you would get from burning the hydrogen.

Correct. Unless Rolls Royce also just figured out how to build a flying nuclear fusion reactor, but I suspect the news would be much bigger in that case.

Considering Rolls Royce is working on space based nuclear reactors, I wouldn't dismiss the notion out of hand.
