Recent news and developments
- December 2012: Bernie Müller has published findings based on his experimentation with a twin Fresnel lens reflector solar cooker. This cooker was never meant to be a production prototype, and his company, Mueller Solartechnik, no longer manufactures solar cookers. As an engineering exercise, he has shown that incorporating the Fresnel lens produces quite high temperatures(278.6°C/534°F). However, the usable cooking area is small.
