The following is a description of an EarthWatch project. This reads like advertising, but EarthWatch is a nonprofit organization in which volunteers assist research scientists with their labor and money contributions.

Based in a residence hall at the University of Nairobi and in field quarters, teams will participate in workshops in which Kenyans adapt and construct solar ovens and, in follow-up studies, to chart the impact of the ovens on household economies in several villages.
