Abstract
A method and apparatus for heating fluids using the Earth's inner heat to generate power and desalinate water. Fluids include fresh water and sea water to be desalinized. The method involves passing a filtered fluid down a channel formed by two concentric tubes in a deep well defining inner and outer channels, to a depth at which the fluid reaches the needed temperature. Hot fluids pass into an inner channel and flow to surface with small heat loss, through an insulated pipe....
