Cyclical energy transfer method and apparatus

Image Number 3 for United States Patent #4022025.

This is a method and apparatus for practicing the method, for the utilization of geothermal energy for the production of power, wherein a fluid (stream and/or hot liquid, or the like) from a geothermal aquifer is brought up the surface of the Earth through several wells of a group, and returned as condensate after passing through an energy extractor through another well, or wells of the group, and wherein a reversible flow arangement is provided whereby the fluid may be taken from different wells and utilized with the condensate going back through different wells successively and in turn by means of which salt deposits are eliminated, the heat of the aquifer is maintained, and maximum energy exraction is achieved.
