Adrian Bowyer envisions a common manufacturing device that could make Wal-Mart practically obsolete. Instead of running out to buy a set of goblets or plates, you'd simply design them on your make-it-all machine and push a button. Poof, whatever you want comes out.
A countertop manufacturing device might make dishes and bowls out of plastic with personalized designs. Fine. But everyone knows what we really could use is the ability to replace temperamental toasters. Won't happen. Special alloys that melt at low temperatures might be employed to allow construction of electronics, Bowyer says, but toasters are out because of the intense heat they must withstand.
Bowyer likens the development process to natural evolution. As the machines replicate, users would tweak them to suit individual needs.
The idea is not new. Bowyer's device, if he succeeds, would be a techno-child of the never-built Universal Constructor, proposed theoretically in the 1950s by mathematician John von Neumann.
