One important new topic at the CONSOLFOOD conference in January 2020 in Faro/Portugal was hybrid cooking, what means that classic solar box cookers are combined with electricity. I met David Chalker, president of the Sun BD Corporation and the most important pioneer in this field in the US, two days before the conference. He had imported hybrid ovens, the so called "Tulsi", from India in 2004 already, and some years later he invented the SunFocus® and the UGLI® Solar Oven by improving the Tulsi in many details.
David tells us his story and shares a lot of his deep insights and the whole solar cooking family should listen to him.
