Proposes that human comfort could be provided in otherwise chilly surroundings by filling the occupied space with electromagnetic energy of cm wavelength. Considerable energy savings could be realized from the resultant ability to lower interior temperatures and maintain comfort in the building. (Author/RE)

The energy required to build and install solar space- and water-heating equipment is compared to the energy saved under two solar growth paths corresponding to high and low rates of solar technology implementation. (Author/RE)
