Global microcomponent redistribution system
From apm
Template:Potentially unstable reasoning tower
Sometime in the future there might be a global microcomponent redistribution system running through our streets into our houses leading to faucets where you tap from or dump to microcomponents (possibly into a portable storage device containing a microcmponent transport metamaterial). These can then via microcomponent recomposers (that are either directly mounted to the faucet or seperate and portable)
blazingly fast extruded to whatever (non-biological) thing you need.
This system would be part of an upgraded street infrastructure. Related: recycling.
