  • August 2018: Solar potluck - William Bradley hosted a solar potluck at his home in Springfield, Massachusetts, USA. The local news channel was invited, and they produced a short video of the gathering. Local family cooks food using nothing but the sun
  • 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.

  • 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.
