Unlike most of MIT, Smith's workshop is far from cutting-edge. There are no next-gen computers, no vials of polysyllabic chemicals, no fancy equipment. The space is decidedly low-tech and that's the point. D-Lab students pinpoint practical problems in the developing countries and then brainstorm and build solutions. Because the people they are trying to help are below the poverty line, the class's inventions must be simple, effective, and most important, inexpensive. "What people need is usually completely different from what we imagine sitting here in America," says Jodie Wu, a mechanical engineering junior, whose group went on a school-sponsored trip to Tanzania over winter break. The idea for her current project a mobile, pedal-powered corn sheller came from a conversation with a Tanzanian bike mechanic. Inventor Amy Smith teaches at the Massachusetts Institute of Technology and served as a Peace Corps Volunteer in Botswana.

At MIT, low-tech inventions with a high impact
The school's basement D-Lab exports simple solutions to the developing world.

Cambridge, Mass.  - Amy Smith is not an easy person to track down. Even during the school year, this inventor and instructor at the Massachusetts Institute of Technology hops over to remote African towns and Latin American villages.
When she is on campus, the best bet for finding Ms. Smith is in her basement laboratory a cluttered workshop with a long whiteboard, exotic souvenirs, and basic tools known as D-Lab.
Unlike most of MIT, Smith's workshop is far from cutting-edge. There are no next-gen computers, no vials of polysyllabic chemicals, no fancy equipment. The space is decidedly low-tech and that's the point. D-Lab students pinpoint practical problems in the developing countries and then brainstorm and build solutions. Because the people they are trying to help are below the poverty line, the class's inventions must be simple, effective, and most important, inexpensive.
"What people need is usually completely different from what we imagine sitting here in America," says Jodie Wu, a mechanical engineering junior, whose group went on a school-sponsored trip to Tanzania over winter break. The idea for her current project a mobile, pedal-powered corn sheller came from a conversation with a Tanzanian bike mechanic.
The D in D-Lab stands for three things development, design, and dissemination and each is the theme of a different semester-long class.
The first class travels to developing countries and identifies issues that the lab can tackle during the next term. For example, in heavily deforested countries, the students found an alternative to firewood.
The design class often filled with different kids takes on the practical engineering. Here they planned and built a charcoal-briquette maker, a metal press that can make clean-burning fuel out of agricultural waste. "It could be corncobs in Tibet and sugar-cane waste in Haiti," says Derek Brine, a teaching assistant.
The third phase takes the students' work and deploys it across the globe.
"These classes are the ones I wish I could have taken during my time here [as a student]," says Smith, herself an MIT-trained mechanical engineer.
D-Lab forces students to set aside their high-tech training. "Though it appears like a step backward in terms of technology, you are moving forward because you learn to do more with less," says Ms. Wu.
This design process takes many rounds of revision. For instance, the briquettemaker was originally a foot-long piston. After many prototypes and field tests, the models got smaller and cheaper. The final six-centimeter-long version inspired a mantra for the D-Lab crew: "When you have to go to a tenth of the cost, reduce the material by 90 percent." Paring down certainly helped in this case the tool, originally $20, is now only $2.
Smith has built her career on this style of practical solutions. In 2004, she won a MacArthur Fellowship often called the "genius award" for creative uses of simple technology to solve everyday problems in developing countries. Smith's early inventions grew out of her four years in Botswana, volunteering for the Peace Corps. Her electricity-free incubator an icebox packed with phase-change pellets keeps samples warm for 24 hours and is an integral part of inexpensive water-testing kits.
Smith's travel continues, but often with teams of students in tow. She has developed a growing, global network of community partners. Each summer, indigenous inventors from across the world come to a design summit hosted by D-Lab to exchange know-how and ideas. Clearly, D also stands for dialogue.
Within a decade, Smith has transformed this cramped basement into a wellspring of ingenious, low-cost inventions. In a sense, says engineering junior Kendra Johnson, Smith's best invention yet is the D-Lab itself.

| Dodd vows to filibuster Surveillance Act Senator Chris Dodd vowed to filibuster the Foreign Intelligence Surveillance Act that would grant retroactive immunity to telecommunications companies that helped this administration violate the civil liberties of Americans. "It is time to say: No more. No more trampling on our Constitution. No more excusing those who violate the rule of law. These are fundamental, basic, eternal principles. They have been around, some of them, for as long as the Magna Carta. They are enduring. What they are not is temporary. And what we do not do in a time where our country is at risk is abandon them." |
