Massive Change interview revisited

When I did the Massive Change interview back in 2004, I was asked mostly about solar home lighting systems and the use of microfinance as a way of making this technology affordable to rural households in the developing world. Aside from a brief discussion of wireless communications, I didn't really go into the multiple ways in which solar energy can be used for a wide range of applications beyond the home at the community level.

At the time, we had just launched our project in northern Nigeria, where each of three villages had been equipped with solar systems for water pumping, school, health clinic, street lighting, mosque, and a microenterprise center. This holistic approach later evolved into what has become our "solar integrated development" (SID) model.
