ABSTRACT:
This energy system comprises a metal sphere equipped on the outside thereof with two centrally located arc-shaped and pivoted arms which meet on the top of the sphere and are joined by means of a spring loaded connection. Each of said arms consists of a bank of spaced convex lenses which focus the rays of the sun into intensely hot focal points on the surface of the sphere. Inside, the sphere are coils of pipe containing water which is converted to steam by means of a heating liquid in which these pipes are immersed, so that the heating liquid which is heated by the surface of the sphere, in turn heats the coiled pipe changing the contained water to steam. The steam is fed to an engine or turbine which in turn powers a dynamo which supplies electrical power. The heating fluid inside the sphere also circulates through a furnace which takes over the heating of the liquid during the absence of the sun's rays. Heat sensing devices spread the arms from the sphere when it becomes overheated beyond a predetermined temperature. In addition the system is provided with the usual control valves, thermostats, and a heat exchanger.
