The solar heater had become a solar cooker. Over the next several years, Augustin contin- ued to work on his solar energy idea, employing his natural creativity and his university training in physics [...] then, Augustin set out to lay the groundwork for his solar dreams in other ways: by writing about his work and applying for patents. Astonishingly, while still being a full-time mathe- matics teacher, he managed [...] to register three patents for his designs, and by 1876, he had achieved suf- ficient fame with his work that the government awarded him a silver medal. Most importantly, though, that year Augustin was granted
