replicator

Hi-tech DIY to solve local problems
Of all the cool, futuristic machines featured on the television series Star Trek, the "replicator" was certainly one of the most useful.
A character simply asked for a cup of tea, and voila - the replicator would make a cuppa. A machine that can make anything sounds like the stuff of the distant future, but a Massachusetts Institute of Technology (MIT) program is making personal fabrication a reality. Around the world, MIT is helping to build Fabrication, or "Fab" Labs, and they are reaping results.
Haakon Karlsen's farm sits hundreds of miles north of the Arctic Circle. The tinkle of sheep bells is a constant reminder that humans, and their animals, have carved out a life here for thousands of years.
He spends a lot of time thinking about how technology can help him tend his flock. "It's not easy to collect sheep in the fall, when it's dark," Karlsen says, pointing to the nearby peaks.
