David Chalker is a solar cooking entrepreneur who’s been around the world and across the US, demonstrating and speaking about his solar electric oven design. After importing the Indian made Tulsi-Hybrid solar oven, promoting it, and selling it for more than 6 years, Dave improved upon it.
From his own design, today Dave manufactures and sells his SunFocus® high-performance solar ovens. Dave is well known in the solar cooking arena. In 2011 he demonstrated his ovens in the courtyard at the Pentagon in Washington, D.C. In 2013 he guest lectured on solar cooking design at Cornell University School of Engineering. In 2014 he spoke as an expert on solar cooking and solar oven marketing at the International Solar Cooking Convention in Sacramento, CA.
In 2017, Dave began development on his new lower-cost design, the UGLI™ Hybrid Solar Electric Oven. After working diligently to perfect the design and bring it to market with the same basic elements as the SunFocus but for a fraction of the cost, he released it for sale in the first quarter of 2018.
