Abstract : This invention relates generally to the field of spacecraft power sources, and more particularly to thermophotovoltaic power sources. There is a continuing interest in the spacecraft arts in finding a power supply which is more durable and reliable than the standard solar cell panels presently utilized. The invention comprises a light energy concentrator and collector, and a thermal vessel including a thermal storage medium disposed in a portion of the vessel and having a light aperture therein for introducing light energy from the concentrator into the vessel so that it impinges on the thermal storage medium.
