@nanomonkey 🤔 i suppose the bootstrap point can be in a different place than i'm thinking. i guess part of the question is how much does it cost to build one community powered entirely by renewable energy? the problem is that a lot of modern society is built on inefficient patterns. if you really want to build a new kind of sustainble culture, it seems like you have to give up a lot of the stuff that we consider "normal" and replace it with substitutes that provide the needed function without the unaccounted externalities.
@luroc i think self-sufficiency is a valuable pattern for promoting more efficient use of energy. i can't find a convicing reason for shipping food half way across the planet when there is enough local produce to go around. there are places where this isn't true, but ideally that is a problem we can solve with hydroponics and other agro-tech. seems like the same logic would apply to building materials, with exceptions for essentials like solar and other advanced resources.
