Abstract

A liquid is evaporated by the sun, raised to as vapor and condensed by passing through a reservoir that condenses the liquid by heat transfer. The liquid is stored in a tank just below this reservoir of water. These tanks are connected to a turbine. Turbine is fed by condensed liquid, and the liquid is evaporated again. The system is closed and the liquid has an intermediate boiling point between ambient temperature in the sun and ambient temperature in the condensing reservoir.

1 . A solar collector and associated piping that has a liquid in that does not need to be insulated against loss of energy and associated condensation of the liquid before the vapor reaches the top of the system. The liquid that is used in the system must have a boiling point between the heat of the solar collector and its surrounding ambient temperature and the colder temperature of the heat sink.  
   
   
       2 . A reservoir for the liquid associated with a heat sink that removes energy from the vapor, until the vapor is below the boiling point, condenses and drips in to the reservoir below it. The heat energy transferred to the water and is in turn transferred to the earth that is in contact with the reservoir.  
   
   
       1 . A solar collector and associated piping that does not have to be insulated against loss of energy and condensation of the liquid before the vapor reaches the heat sink at the top of the system. The liquid that is used in the system must have a boiling point between the solar collector and the heat sink at the top of the system.  
   
   
       2 . A heat sink is added to traditional systems. At the highest elevation of the system, a large body of liquid (usually water) is stored with a large surface area of the liquid in contact with the earth. This liquid transfers the energy of the liquid of the system (in this case, Pentane) into the heat sink (the earth through the medium of the water reservoir).
