On December 16-17, 1974 a workshop on "Future Developments in Waste Heat Utilization" was held at Portland, Oregon under the direction of Oregon State University and sponsored by the Energy-Related General Research Office, Research Directorate, National Science Foundation. During the last few years, numerous research projects aimed at finding beneficial uses for waste heat have been initiated. There was a need to: Summarize current activities in a meeting where all concerned organizations and disciplines are represented. Exchange information on current programs. Obtain the views of the power generating industry. Obtain the views of potential users of waste heat. Make recommendations for future research and development. This workshop was an attempt to respond to these needs. Sixty-two researchers in the field of waste water utilization participated in the workshop. This constituted a national representation from universities, industries and government agencies. This report summarizes the results of the intensive two -day discussion
