Q: When I think of the steps to settling space, I think of it mostly in terms of technology and economics. If you don’t need to be economically self-sustaining, we’ve had the technology to build a moon base for decades – just spend $100k/kg on food and other things to sustain it that we don’t have … More Moon, space, profit, strategy, Q/A
Q: Instead of water, what would you propose they focus on at a moon base? BTW The savings from reusability are in addition to the savings from not having to launch fuel from Earth. But even getting fuel derived from the Moon or asteroids will not be free, since it will still be quite a hassle. … More Moon, ideology, Q/A. Water.

People quite regularly notice that I do use energy metrics and ignore economic realities in my assumptions. There are few good reasons for that. And let’s consider some aspects on an example of the problem of using smart matter on a large scale for megastructures like space lifts or other stuff. A point about economics … More Smart matter, Q2, economics vs energy and other animals
Ok, I got a valid question about what you gonna do with all those presumably available K1(10^18W) energy, in terms of production in space, which I have broadened to activity in space. If you do consider that the improvement of technologies is not required to meaningfully utilize the energy. It is a lot of energy … More K1 energy budget. Is it too much for us?
Or rather how a tool capable of moving the planets can be done. TL;DR Build a planet big spaceship, move stuff with the gravity of that ship, using star energy for propulsion solar sail like. Or by pressing on the planet by a huge shell. As reasons to move planet are not given, so are not … More How can I move a planet?
