Reply to comment by GreenAdvance in Rolls-Royce successfully tests hydrogen-powered jet engine | Britain's Rolls-Royce said it has successfully run an aircraft engine on hydrogen, a world aviation first that marks a major step towards proving the gas could be key to decarbonising air travel. by yourSAS

Exactly what this should be for now. Who know what nuclear can do if allow to advance.

There is no replacement for gasoline in commercial flight. Even if such technology exist, it probably won't implemented due to the cost of building an aircraft ($10 to $20B).

No company will be taking such as risk. Politicians will do it, because it is not their money and a big payout for their buddies.

This is literally about replacing gasoline with hydrogen.

Maybe don't embarrass yourself.

  1. Aircraft don't run on gasoline

  2. You don't need to design a plane from scratch for a new engine. BROADLY speaking it's mainly the horizontal tail that needs to be redesigned to account for the pitching moment from the engines. The problem with hydrogen is its lower energy density than aircraft fuel. It's the reason why electric jets don't exist

  3. This would probably be for future aircraft not retrofits.

  4. You clearly have no idea what you're talking about.
