The Fab Lab
In Pabal, an Indian village with a population of 5,000, a dairy farmer's income is tied to the fat content of his cow's milk. Students at the nearby Vigyan Ashram science school are using a fab lab to build a sensor that will give Pabal's farmers a precise measure of that fat content. In Takoradi, Ghana, people have used the labs to produce a cassava grinder, jewellery, car parts, agricultural tools and communication equipment such as radio antennas. Solar-powered items to harness the relentless local sunlight are in the works. In Norway, Sami animal herders—who are among Europe's last nomads—are using fab labs to make radio collars and wireless networks to track their charges. And in Boston (admittedly not part of the developing world, but conveniently near MIT), the residents of a mixed-income housing complex are using one of Dr Gershenfeld's labs to create a wireless communication network.
The Fab Lab costs $20,000 -- a lot at face value, but not much considering that it does the job of machinery that costs much more. Some analysts have compared the revolutionary impact of the Fab Lab to that of the personal computers, which took computing out of the labs and brought it to the masses... and lowered costs dramatically.
