The Hypar Solar Cooker is a parabolic solar cooker designed by William Bradley, founder of Earthbound Technology. According to the designer, it is a new type of solar cooker that is easier and less labor intensive to build than most parabolic cookers. The Hypar Cooker is primarily a multi-sided parabolic with the outermost portion of the parabola replaced with a conic section.

Bradley feels the Hypar cooker is safer than typical parabolic cookers because, with the multisided parabola, the focal point is spread over a focal area. Also, the focal area is located inside the Hypar cooker making it safer than cookers that have the focal point located outside the cooker.

  • 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.
