IIRC, it actually is but it takes a really large amount of energy. If
the sun were 100% converted to energy, it still wouldn't be enough.


I doubt that.
And what volume of water compressed by how much?

Plutonium "fission" atom bombs originally (and probably still) work on
"implosion". Explosives around the plutonium reduce the volume of the
solid metal sphere to 1/2 the original volume (so the entire sphere is
suddenly "critical").



The info I see is the plutonium is a hollow sphere filled with hydrogen
gas, so relative easy to compress with the bomb around it that sets it
off. It is not a solid sphere.

No Plutonium bombs were "gun" type bombs. Half the Pt was at one end
of the "barrel" and it was fired into the other half to become
critical.

I think you have that backward. The "Little boy" gun bomb used U-235
and "Fat Man" implosion bomb used plutonium.
That is why newcomers to the nuclear arms race are enriching uranium.
The gun bomb is a whole lot simpler to build.
