Its comparable. Sure Mars is colder, but cold isn't an issue after you have a coat/insulated building. Its really all air food and water. Air and water come from ... water and electricity. So that leaves food. It can be hard to grow anything in a greenhouse in the winter - insulation blocks sunlight, which isn't any too bright out there already. So that leaves farming with lights in tanks, underground, or in insulated domes etc. Which will end up costing more than the human infrastructure. E.g. it can take a quarter acre of land to grow food for you; you can live in 500 sq ft. Orders of magnitude different. |
