How can traditional forms of technology be developed to become more environmentally friendly? In Nepal, farmers have been grinding rice and grains with water mills, called ghattas, for centuries. Now they're being converted to become more energy-efficient and even to produce electricity.
Nepal has about 25,000 traditional water mills scattered throughout the country. 6,500 of them already have been converted. These new and improved water mills are a climate-friendly alternative, and could serve as a model for other countries in Asia.
