The Revolution in Electrical Energy Sources A State-of-the-Art Review

The state-of-the-art of direct-energy-conversion techniques, including solar cells, thermoelectrics, and thermionics are reviewed. While the greatest impetus for new methods of power generation stems from military and space requirements, the resultant technology will eventually have significant impact on commercial and domestic power generation, especially in situations where conventional electrical power sources are either nonexistent or inadequate.
