PHOTO: BOB TOWERS, NATIONAL GEOGRAPHIC STOCK Smoking Hot Sunlight focused on a reflective disk bounces back enough heat to light a cigarette in Phoenix, Arizona. This solar-cooker demonstration, part of the World Symposium on Applied Solar Energy, was one of 85 displays from 50 exhibitors on the grounds of the Phoenix Public Library in the fall of 1955. Some 29,000 people came to marvel at sun-powered sights, from electricity generation to furnaces to baking cinnamon rolls. But the Cold War may have prevented a warm welcome for visiting Russian solar scientists. "The Soviet exhibit created a few questions," note the photographer's captions. "There appeared neither the scheduled exhibit or exhibitor." ---Margaret G. Zackowitz O Flashback Archive Find all the photos at ngm.com.
