From there:
My suggestion for a "Game Changing" project is that NASA (possibly in partnership with NIST) could coordinate a global effort towards designing and deploying self-replicating space habitats that can duplicate themselves from sunlight and asteroidal ore (developed under free and open source non-proprietary licenses as progress towards "open manufacturing").
NASA showed the basic technological feasibility of this with work in the late 1970s on space habitats, and also in a 1980 study called "Advanced Automation for Space Missions".
In a long-term space mission or a space settlement, a self-sustaining economy must be created and supported. Therefore, addressing the problem of technological fragility on Earth due to long supply lines and the inaccessibility of key manufacturing data (because it is considered proprietary) is an essential step in the development of the development of human settlement in space. Addressing such fragility would have immediate benefits to improve intrinsic and mutual security globally, and would help humanity survive in the face of plagues, wars, global climate change, asteroid strikes, earthquakes, and whatever other disasters might strike unexpectedly. As the loss of New Orleans showed, Mother Nature remains a formidable adversary even when people are not fighting amongst themselves over perceived scarce resources.
A NASA-coordinated effort to organize manufacturing information and use it to design such habitats (or seeds that would grow such habitats), as well as improve the state-of-the-art in collaboration software, could thus help meet needs both currently on Earth and in the future in space.
Nothing NASA is doing now compares with this at all in terms of gaining the excitement and participation of the world's technologists and technically-minded youth, given this project would have the scale of the entire FOSS movement applied to manufacturing (and simulation). Achieving this goal of a self-replicating space habitat could justify literally trillions of dollars in effort to create a technological infrastructure that could support quadrillions of human lives in space, making nonsense of current worries of "Limits to Growth" or "Peak Oil" or "Overpopulation" or whatever else.
While NASA could coordinate this effort, many other organizations including NIST (and its SLIM program), DARPA, universities, and manufacturers globally could also participate in this effort.
As a whole, this project would help increase US security as a sort of public outreach by helping the global security community transcend ironic and outdated visions of what security means, given that so much abundance is possible through modern technology and this NASA effort would demonstrate that:
"Recognizing irony is key to transcending militarism "

This effort could also be done in conjunction with this other proposal I made:
"Build 21000 flexible fabrication facilities across the USA "
