Other Solar Cooking Interests
- Tracking systems for solar cookers
- Review the performance of funnel cookers
- Increase the power flow into box cookers by optimizng the size and orientation of reflectors.
- NEW: June 2017: Reciprocal optical testing - Earthboundtech conducted their reciprocal optical testing on the Hypar Solar Cooker and Parvati Solar Cooker in April 2017, and used comparative data from a CooKit analysis done in 2014. The Hyper solar cooker reflector utilizes a combination of a conical outer ring with a parabolic inner dish. This allows for more diffuse solar energy directed at the cookpot, while still having some concentration that a parabolic reflector can provide. More information on reciprocal optical testing procedures and results can be found on their website at http://www.earthboundtech.com/optical-test.
- April 2014: A photo is used to evaluate solar cooker output William Bradley, founder of Earthbound Technology, has been working on developing a new approach for analyzing the potential performance output for solar panel cooker and parabolic solar cookers. It involves photographing the cookpot as the light source in controlled light conditions, and measuring the reflected light.

- February 2013: The Hypar Solar Cooker is currently being tested. It is our newest cooker. It is primarily a multi-sided parabolic solar cooker with the outermost section replaced with a conic section. Testing midwinter in Massachusetts shows that it can produce more than enough heat for cooking.
- July 26, 2008: We cooked a complete meal for 15 people completely in the sun and did a presentation on solar cooking after the meal. It was a complete meal including appetizers, main course and dessert. This attracted enough attention to have the local TV station send a photographer and we had our moment on fame on the local news.
