- Udo 11y agoIf you're really after those 3 Kelvin, you might be happier selecting a host star that is 3 degrees hotter instead, especially considering the practical efficiencies of heat exchange systems near absolute zero temperatures.
- cousin_it 11y agoIf your computer can operate near the Landauer limit, then cooling it to ~10^-7 K makes computing operations cheaper by a factor of ~10^7. Using a 3 K warmer heat source won't accomplish the same.
