*Certainly, but when your heat sink gets colder and colder eventually
you reach a point of diminishing returns, and at 2.7° kelvin that point has
been reached because the difference between **0.99353% efficiency and
**0.9999999999983% efficiency
is too trivial to worry about. It's certainly not worth the trouble of
compressing Jupiter into a 20 foot wide Black Hole which, correct me if I'm
wrong, I believe would be rather troublesome to do. *

*If there are better ways of producing amounts of power that are LITERALLY
astronomical and keep doing so for billions of years than Dyson spheres I
have not heard of them, but I do know one thing, even if they exist they
would still have to obey the Second Law Of Thermodynamics, and that means
we should be able to observe them. But we have seen nothing.   *
