Solar electrical generator

Patent ·
OSTI ID:6407394

The engine of the present invention includes a cylindrical, elongated boiler housing with a turbine mounted within it, and the turbine and boiler rotate relative to each other. Heat is applied to the outside of the boiler and converts a liquid working fluid in the boiler to vapor. A shroud in the boiler directs the vapor to the turbine to cause the turbine to rotate in one direction. Because the boiler can rotate, the boiler and shroud rotate about the shaft in a direction opposite the rotation of the turbine. Centrifugal force holds the liquid working fluid against the boiler walls. After passing through the turbine, the working fluid is condensed and it is injected through a hole into the boiler by centrifugal force. The novel condenser which rotates with the boiler housing relies on the centrifugal force developed by rotation. Solar energy, the preferred heat source, is concentrated to a hot line on the boiler. The rotation of the boiler exposes the entire surface to the hot line. The solar collectors are in an array to concentrate the solar energy into two hot lines, one on each side of the boiler. An insulating enclosure around the boiler maintains the heat of the boiler, but windows are provided through the enclosure for allowing the hot lines to pass through.
