Nilsson, Sr, J E

A method and apparatus for collecting, intensifying and storing solar energy which includes a hollow spherical vessel 10 having a polished reflective interior surface. A window 32 is provided in the wall of the vessel for allowing concentrated rays from the sun to enter into the interior of the vessel and be absorbed by a solar collector 20. The collector includes a substantially black (or a selective coating) heat absorbing surface carried by a spherical member 16 which is centrally located within the spherical vessel. Heat absorbing media 18 such as metal shots are carried within the spherical member and change from a solid state to a liquid state as it absorbs the solar energy. The heat absorbing media 18 cause radiant energy to be radiated radially in a symmetric beam pattern to the reflective vessel wall where the radiation is reflected back to the spherical member 16. The reflected radiant energy, in conjunction with the sun's rays, intensify the temperature of the heat absorbing media, producing a thermal power supply.
