In fact I should confess that I only posted my comments in a very modest
effort to promote lighter-than-air (LTA) as a more viable option for such
things. Of course the "open" technical challenges and usage tradeoffs of
a
personal "portable(!?)" airship are quite different from rotorcraft.

Would this sort of concept use He and a compressor to recover it after a
flight, or hot air?

He would, I think, take a lot of compressing to make it portable - Right?
Wrong?

I assume you are talking about something with power - one fuel could
provide power and the heat for hot air. The engine cooling / exhaust would
help maintain the temperature inside the envelope?
