This article sounds to me a bit like the talk back in the 50's about flying cars. How in the world does a washing machine repairman carrying around a fabrication machine make any sense? It will always be more practical and cost-effective to just bring the part from the warehouse. I don't see how it has advantages from the "green" perspective, either. Maintaining, transporting, and feeding such a machine requires a whole energy-consuming infrastructure.
