Plants for Life (PFL), a Nepalese NGO, has disseminated several renewable energy technologies via an integrated program that gives high priority to socially disadvantaged groups, e.g., the untouchable caste.
The program has been effective in the Eastern and Central part of Nepal, especially in the Churia Hillsarea, which has been affected by heavy deforestation and consequently, erosion, flood, andecological imbalance. 40% of the population Iives in absolute poverty and is totally dependent on free forest resources.
Within the past 3 years, over 300 biogas plants and over 200 improved cooking stoves have been disseminated, while 600 families received loans and training. Of these, 90% changed their firewood-selling trade into small alternative businesses. Further, at least 45 solar box cookers have been fabricated by rural women within the last year. Other solar thermal and wind-energy applications are currently under development.
The PFL solar energy subprogram is supported by Technology for Life (TFL) a Finnish NGO (member of INforSE).
A recent development is a parabolic solar cooker constructed with mainly local materials in 3 days. The cost of materials was only $3. It has two parabolic bamboo baskets about 1 m in diameter each. A mixture of clay, cow dung, mustard oil cake, and pedihusk is prepared, pasted on the parabolic baskets, dried, smoothed, dried again and sanded. Finaly, aluminium reflector paper is glued onto the surface. A bamboo crate holds the parabolic baskets, allowing them to move vertically from 30 to 90 degrees. The model can cook 0.5 kg rice in 35 min. with adjustments every 12-15 min. This is much quicker than solar box cookers. Further improvements are under way.
