I would like to add that co-generation is useful with solar energy technology as well. Photovoltaic cells are relatively expensive and it is not easy to increase their efficiency. But they can be augmented with cheap technology of solar heat collector (water warmer). I learned this idea from Prof. Wasaburo Unno, a theoretical astrophysicist (retired from the University of Tokyo). He promotes his idea at his web site, http://www.easy-db.net/unno/ . The contents there are mostly in Japanese because he wants to involve ordinary Japanese citizens. But there is at least an abstract in English. His group also has specific ideas of technological elements such as concentrating light by a system of mirrors (astronomical technology!) and of preserving heat in stratified water (maybe geophysical fluid dynamic technology?). I do not think his movement so unique as he himself promotes, but I think that his idea hits an important general point of co-generation. Ko-1 M.
