- July 2011 - June 2012: International opportunity for testing solar cooker designs - Originally announced as a one-time event Oct. 11-13, 2011 with a related conference, the solar cooker competition has been cancelled, and instead there will be a year-long opportunity for having solar cookers and fuel stoves tested free. India’s Promoters and Researchers in Non-Conventional Energy (PRINCE) group has updated standards for solar cookers, developed in conjunction with input from SCWNet members. These universal testing standards will be used to evaluate the cookers by simulating real world conditions. Designers, manufacturers, NGOs and individuals are invited to submit solar cookers for testing, and need not be present for the tests. While there will be no cash prizes, solar cookers will be rated on thermal performance, cost of manufacture and transport, and user convenience. Send cookers anytime between now and June 2012 to: Prof. Ajay Chandak, PRINCE, Shamgiri, Opp Swagat Lodge, Agra Road, Deopur, Dhuli – 424005, Maharashtra, India. Include your usual instructions for consumers. If you wish your cooker returned, please arrange to cover return shipping costs. After testing, entrants will be contacted with results, and have the option of omitting their information in the publicly listed ratings. No reply from entrants within two weeks or so after receiving their results will be taken as consent to publish. Other questions? Email: firstname.lastname@example.org.
