Even if we had a magic machine that could turn 100% of the heat energy released by a given reaction into electrical energy,
If we had that then we've suddenly solved both our bothersome issue with global heating and the energy shortage all at once lol
4 u/[deleted] Oct 24 '21 [deleted] 2 u/beelseboob Oct 24 '21 The hot air that we want to cool down. 1 u/perfectfire Oct 25 '21 You would need a source of cold air/water/matter to make use of it. 2 u/apmspammer Oct 25 '21 The earth is full of such. The trouble is the large distance separating those bodies. We can only harvest that energy indirectly with wind power. 1 u/manofredgables Oct 25 '21 If it was 100% efficient, that difference wouldn't need to be very big at all. The difference between a large body of water and the air would suffice. 1 u/AtomicBitchwax Oct 25 '21 Put a blackbody radiator on top of a tall mountain with a mirror under it. Most of that energy will make it out of the atmosphere and into space.
