That's interesting. I wonder how well we can shoot our waste heat into space?

E = mc^2, so convert the energy into mass and shoot it into space?

In principle heat can be gotten rid of with radiators, like the EATCS[1] on the International Space Station.

To maximize the heat radiated away, you'd need radiators with as much surface area as possible with an unobstructed view of the sky (no cloud cover). They'd also need to be as hot as possible, because thermal radiation power rises with the 4th power of absolute temperature

There have been attempts to detect such thermal radiation from alien civilizations[2].
