It doesn't violate laws of thermo was my point. Science fiction is what things are called before they are technically possible (in some cases.) We all know this vision is hypothetical.

So does it violate current laws of thermo or not?

I figured youd go with that. So apparently you did you not read the third paragraph ("something more likely")? How does a Dyson sphere ignore the basic laws of thermo?

Nah but your comment is simply frivolous / empty

What if technology which is incredibly inefficient (energy wise) is paired with future technology which unleashes zero point energy (say, near unlimited)

Would block chain then be a futuristic sustainable technology?

Backing up, something more likely; ex: Dyson sphere around some other sun, and being able to compute on premise and send results far away.

Sleep with window open, no matter the winter season.
