Abstract
A system for the collection and conversion of solar radiated power into electrical energy. The system improves present solar power conversion systems by locating key elements deep underground, thereby greatly decreasing thermal losses and increasing system efficiency to an estimated 80 percent. In particular, a vertical mine shaft, at least 100 meters deep is used for transmitting collected solar flux from above ground heliostat fields, down to an insulated boiler. The boiler converts injected water into superheated steam which drives a steam turbine connected to an alternator or generator producing 50 to 100 Mw electrical power. Provision is made for an auxiliary drive system, using stored water or stored heat to operate the generator during hours of darkness or high load demand.
