And this happens at the same energy whether the impetus is gravity, lasers, or Maxwell’s Demons.

Sure, but the question is how to compare the rate of reaction at some P-T to the rate of reaction in the sun, which we know to be "slow", in fact about 1 watt per ton.

That's nowhere near "ignition", which is being sought in the ICF experiments. I only recently learned of a type of supernova caused by "pair production instability" which does actually represent a star exploding like an H-bomb, with near 100% efficiency due to its size. Mind-boggling.

ICF is striving for a pinhead portion of one of these, not the slow simmering sun. In fact, reading the ICF article, it's hard not to scoff.
