For a recent issue of Physics World, he writes about the history of stoves and ovens, and how physics is tackling some of the environmental and resource usage issues associated with cooking.

"Despite the rapid development of cooking technology and its gastronomic application since 1800," Perkowitz writes, "two to three billion people worldwide, mostly in developing countries, still eat food prepared by the ancient method of cooking over open fires or in rudimentary stoves fed by solid fuel – wood, agricultural residue, animal dung and sometimes coal.
