Hartmut Ehmler lives in Berlin, Germany, and is the designer of the Lightoven I, Lightoven II, and the Lightoven III. He began experimenting with solar cooker designs in 1991, but set it aside, until he rediscovered his interest in 2010. He wished to design a solar cooker that would be lightweight and compact, easily taken camping or for other outdoor activities. This lead to the design of the Lightoven.
Besides using the Lightovens, he also cooks with a Global Sun Oven. He began teaching solar cooking in 2010, and he has taught 150 people to solar cook up to the summer of 2014.
