In an inverse Dyson sphere around a black hole you use the temperature difference between background radiation outside and the near zero of the black hole to generate useful power. Not practical in the current universe as 3K is a bit low. https://t.co/6F

@RevistaMigala esto quizás le parezca interesante al hobbit... si se saltan los cálculos de temperatura y radiación y eso, pues el resto es comprensible por cualquiera :3

https://t.co/8rwNElpfOv 地球外知的生命がブラックホールの周りにダイソン球を作るとしたら,カルダシェフスケールIIの文明を維持するエネルギー供給は可能か?また,そんなものがあったら我々から観測可能か,ということを真面目に考えた論文.
"A Dyson sphere around a black hole" ETCs maybe benefit from a black hole than a star. If such ETC exist in the Galaxy, it might be detectable with our current technology. https://t.co/i9rhzGP4yr
