Solar Energy-Fuel and Food Workshop Proceedings, April 5-6, 1976, Tucson, Arizona, edited by Merle Jensen, 258 pp., $5 per copy (checks payable to Univ. of Arizona) from: Environmental Research Lab Tucson International Airport Tucson, AZ 85706 · Includes 17 reports from U.S. Dept. of Agriculture- Agricultural Research Service, corporate and university researchers with emphasis on retro-fitting large commercial greenhouses for energy conservation and solar heating via a variety of methods. Only one of thereports, starting on page 129, considers the possibility, for new greenhouses, of a direct (i.e. passive) solar design in which the greenhouse is the collectorstorage system a l<I; Brace Research Institute, New Alchemy Institute; Reichmuth-Barnes and others listed in the "Models" section. However, forewarned of this shortcoming, home and commercial greenhouse builders will still glean some useful hints. Best of all, the name and address list of participants at the back will aid you in contacting nearby resource people for answers to specific questions. (Courtesy Bill Rice, ERDA) -Lee Johnson
