What assumptions? Plutonium 238 doesnít even produce neutrons, it
produced Alpha Particles (Helium), how on earth (or Saturn) are you
going to make a chain reaction from Alpha Particles?! Plutonium 239 can
make a bomb but not 238, and nobody puts Plutonium 239 in space probes.
And if all you needed to do to get a fusion reaction going is get a
bunch of Deuterium together we would have had practical fusion reactors
a long time ago.

And you say that in the center of a gas giant planet matter is in a
degenerate state just like it is in a White Dwarf star; and that is also
Bullshit. Compared to a White Dwarf the center of Jupiter is a pretty
good vacuum and itís cold as hell too.

Youíre right that people think the idea is ridiculous, and there is a
reason for that.
