Global microcomponent redistribution system
From apm
(Speculativity warning!)
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. 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.
