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
Q: I read your article “How can I move a planet?” the other day. I’m not sure I understood the device, is it some kind of GIGANTIC mechanical arm that stores elastic energy to harvest matter? no, it isn’t a big mechanical arm, kinda. youtube links there are important to watch. all in the article is actually a fluff, … More Smart matter, clarification, Q1
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?
Let’s take a brief look at resources available on the moon and what they mean in terms of a growing system in place and aspects which might be interesting in the context of Plan0. Just fast recap. Gravity 1/6 of earth(1.62m/s^2), escape velocity 2.38 km/s Energy Energy wise things aren’t too good but aren’t bad … More Moon. Moon resources. Tech seed. Plan0.
or how to look in the future in a right way Any technological solution contains a lot of details to consider when implementing it. The technology of making a Stone Axe is relatively complex one and tricky enough and need a certain level of expertise, a certain degree of knowledge about material selection and techniques … More Ideology of technological solutions
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?
We are one step ahead.The question is not how far away we are, but how small we can make it for practical purposes.And how well we have documented the plan for tech-seed to grow. The real growth of our technologies started in late 19 century and the beginning of 20th century.The amount of information and … More How far away are we from a 14mt clanking replicator architecture?
I highly recommend to read: O’Neill, G. K: The Colonization of Space, Physics Today, vol. 27, no. 9, Sept. 1974, pp. 32–40. Up to 16km radius is doable with usual materials.

Q:Now assume Joe is an average white American citizen who has attended college and earns 50,000 USD annually. In addition to his salary, he has 100,000 USD in his bank account. He has no family and is prepared to spend any time, effort, and/or money needed to create a country (most likely a micro-state) that … More How can Average Joe create a micro-state that is a member of the UN in the least amount of time?
Q:Giant Planetary Ring Bases (or GPRB’s) are space stations built on planetary rings or are artificial rings themselves, such as Starship Troopers’ Luna Base. But are these super stations feasible? Assuming the ring is 30 by 30 meters all the way around the planet, would it be realistic to build such a structure? A: Yes, … More Giant Planetary Ring Bases, are they feasible?
