Futurism

A place to discuss the ideas, developments, and technology that can and will shape the future of civilization.

Tenets:

(1) Concepts are often better treated in isolation -- eg: "what if energy became near zero cost?"
(2) Consider the law of unintended consequences -- eg: "if this happens, then these other systems fail"
(3) Pseudoscience and speculative physics are not welcome. Keep it grounded in reality.
(4) We are here to explore the parameter spaces of the future -- these includes political system changes that advances may trigger. Keep political discussions abstract and not about current affairs.
(5) No pumping of vapourware -- eg: battery tech announcements.

I want ethylene gas from atmospheric water and carbon dioxide, in a counter-top sized reactor that is fed only electricity and draws the gas from the air. Then makes polyethylene feedstock for an attached 3D printer. Plus an attached shredder to recycle your polyethylene creations when you're done with it.

If I'm Elon-rich and also SpaceX-Elon thinking about manufacturing plastic things on Mars to support local production, I'm all over this.
