Heat doesn't radiate like that in space. This topic comes up on HN often enough. There isn't anything to carry the heat away because space is, by definition, empty. The energy has to be carried away by something. Cooling space stations is a legit real problem. The only thing space gets you is somewhat better solar efficiency, but we aren't lacking of land to build solar panels on here on earth. |

What do you mean? I stated black body radiation numbers.
>There isn't anything to carry the heat away because space is, by definition, empty.
Heat radiation. Which is what Sun for example does in that empty space.
>Cooling space stations is a legit real problem.
Please, numbers. Otherwise it is just some hand-waving.

Space gets you away from regulations, corrupt bureaucrats, and the threat of war/terrorism/etc. for example. At $100/Kg building in space looks to be just cheaper. And space allows to have solar and datacenter in the same unit, while on Earth you have to deliver your electricity from a solar farm somewhere to the datacenter. There is a reason Oracle started to talk nuclear in the datacenter. And between nuclear in the datacenter on Earth and solar+datacenter in space at $100/Kg i think the space scenario would be simpler and cheaper.
