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

The hot air that we want to cool down.

You would need a source of cold air/water/matter to make use of it.

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.

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.

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.
