Renewable Energy Advocates Offer Invention That Can Harness and Ease Global Warming.
Here’s a Zen riddle: How can the greenhouse effect help reduce the
The answer, according to a growing number of people, is “solar cookers.” And to prove the point, people in such diverse settings as the foothills of Nepal, refugee camps in Kenya, and the American Southwest are turning to the sun to boil rice, bake potatoes and even pasteurize camel’s milk.
