TOKYO -- Decades of research into green energy by Japanese companies are beginning to bear fruit. Auto component maker Denso plans to start testing this autumn on a biofuel made from algae extracts.
The organisms are potentially an ideal source of clean energy and have attracted attention as a possible alternative to fossil fuels. There are more than 50,000 varieties of algae, which absorb carbon dioxide from the air during photosynthesis, producing oil and nutrients.
