A friend of mine, Walter Bradley, who I credit for introducing me to the idea of appropriate technologies for developing countries, has spun off a new company with two of his graduate students. They recently have been getting a lot of press like this story on MSNBC.
What is appropriate technology? It is the idea of using technologies that are culturally, environmentally, and financially appropriate for the cultures in which they are used. They are often low tech, or medium tech by US standards. They must be locally repairable, locally affordable, and sensitive to other aspects of the culture.
I would give an example but I am too tired... maybe more tomorrow, maybe not.
