My response could be seen as a bit unkind - I apologise.
I do agree that we should be looking at alternative fuel sources for aviation and other things. This would be for my great granchildren as I don't really believe we are close to the point of running out of oil anytime soon (another discussion if we could leave it there)
Any increased efficiency in electrical power generation would be a good thing I agree. However I do still believe that you have some incorrect assumptions in regard to engine operation.
Kind regards
