Abstract
Developments in the field of thermoelectrics and thermionics over the past year are summarized. The status of each is discussed in relation to the evolution of practical devices utilizing these two forms of direct energy conversion (of heat to electricity). Practical thermoelectric devices are now in use for terrestrial and space power operations. Application of thermionics to practical devices has advanced to the development stage for use in space power systems.
