ABSTRACT:
A combined solar power generator and water purifier is provided herein. It includes a hollow globular boiler floating on and anchored atop a body of water to be purified. The globular boiler includes water inlet means disposed adjacent an upper portion of the globular boiler, an upwardly directed steam outlet conduit originating from an upper portion of the globular boiler, and a refractor lens window disposed within an upper half of the globular boiler. Controllable means are provided for directing the sun's rays towards the refractor lens window to generate heat to boil water in the boiler. A primary turbine is disposed at a level above that of the boiler, the primary turbine being connected to the steam outlet conduit and being driven by steam under pressure from the boiler. Steam condenser means are connected to the outlet from the primary turbine for dissipating residual heat in the steam effluent from the turbine and for condensing such steam as substantially pure water. A reservoir is connected to the outlet from the condenser means and such reservoir is disposed at a level which is lower than that of the primary turbine, but at a level which is higher than that of the globular boiler, for receiving such substantially pure water. A secondary turbine for the generation of electricity is disposed at a level which is lower than that of the reservoir but which is higher than that of the globular boiler. The secondary turbine is connected to the outlet from the reservoir and is driven by water from the reservoir. A pure water effluent is provided from the secondary turbine for use wherever pure water is required. Such solar power generator is thus very energy efficient.
