Big brain tech dude got yet another clueless take over at HackerNews etc? Here's the place to vent. Orange site, VC foolishness, all welcome.

This is not debate club. Unless it’s amusing debate.

Yup, they can only dump heat through infrared radiation. The giant white fins on the ISS are radiators for waste heat.

I think there is another way to dump wase heat. Use it to warm up something that has a lot of heat capacity, and then eject that. Not practical and a huge waste (I also got this from science fiction), so you know they are going to try it. Gonna suck for us groundies.

Theoretically you could heat pump but the energy required to make it work would probably would probably be more than it's usability

You also need to launch metals back up from earth to replace things. So it is all horribly inefficient
