Good point. I would still want an enclosure or inner hull perhaps
clear plastic?  If the gravity bubble were to collapse suddenly
would that create a blackhole?  ( I'm out of my league here! )
...just a thought...

I've noticed this about certain subject matter especially on the web.
Pages seem to appear and then disappear with the ol' 404 error
page not available.   There was a British gent' who discovered a
way of converting old crankcase oil into a cheap but highly effective
rocket fuel with household/shop chemicals one being methyl alcohol.
I don't remember the other additives ...and....I can't find the webpage.

Yes, why not?  Could a small microwave oven be converted to power
a small pSub in this manner?  The wireless network community had
found a way of using a "Pringles" can ( like in potato chips ) as a wave
guide for point-to-point wireless communication. Apparently the can is
perfectly
shaped to generate 2.4 Ghz.   I don't know what kind of heat this would
generate for the can before, and if, it would breakdown, but other materials
could be used following this simple design.
