cucigy. According to Previews lecturer, Mr. Stuart Guttentag, who will appear here with the show, the solar energy falling on one square mile of ground each day is equivalent to the energy in 400,000 gallons of oil. The Sunmobile illustrates one method of recovering some of this energy. Among eight other demonstrations in the Previews show are a roaring Jet engine, a vivid illustration of the gyroscopic principles that safely guide today's s'hips, planes and missiles, on an air-bearing platform that slides across any flat surface on a thin layer of air. Designed to inspire greater Interest in science and engineering, the 45-minute stage show is presented in non-technical language by a specially trained two-man team. Seven teams take the program to all parts of the nation. Since 1946, Previews of Progress has been seen by nearly 35 million people in the United States, Canada and 22 foreign countries.
