The world needs a new source of energy, an unspillable source.

Has hydrogen ever been used as a fuel for Buoyancy Assisted Aircraft (BAA)?”?

Seems like the Egg of Columbus” to me, but I’ve been told I have an uncanny grasp of the obvious.
Given the huge volume of the pressure envelope and abundance and dependability of sunlight above the clouds, Hydrogen could be produced on board by photo-voltaic cells.

Could this BAA actually land with MORE FUEL than it had at take-off?

BMW has a Hydrogen Engine in a limited-production 760 series sedan.
And Germany is producing NT (New Technology) Zeppelins.

John, your answer was so thorough that nobody else was answering. so I started new. I seen to get my best response in the first hour.
How can I give you “Best Answer” when it is the only answer?
Who would answer the Question after that?
And if you don’t think I can take criticisms, you haven’t read many answers to my questions.
They run 10-1 negative and often insulting. I seldom insult back.
