Abstract: A system for electromagnetically transferring heat from one region to another region. To cool one region in a chamber, antennas in the chamber to be cooled preferably have a broad beam to collect thermal radiation as much as possible within the chamber. Antennas to be used for heat pumping are preferably of high directivity where the antenna beam is pointed to a cold region such as the zenith of the sky. The system for electromagnetic heating is similar to that for electromagnetic cooling except heat flow is reversed. Here, the antennas outside a chamber have a highly focused beam to a hot area, such as the sun. The collected heat is channeled into an area to be heated by low-directivity antennas within an enclosed volume to be heated.
