Patent ID: 8307896

Claim:
A method for heating fluids with earth's internal energy, comprising: passing filtered fluid down a drilled well, containing concentric inner and outer tubes that form inner and outer fluid channels, to a depth at which the fluid is heated to a specified temperature and pressure due to heat transferred from surrounding rock, passing the heated and pressurized fluid to the inner fluid channel through slots which are located near a lowest part of the inner fluid channel, passing the heated and pressurized fluid to the surface by ascending through said inner fluid channel so that the fluid allows for power generation, or for seawater desalination in an integral process with power generation, controlling pressure of the ascending fluid with a valve and a pump, controlling amplitude of horizontal vibrations of the inner tube with separators attached to an external wall of the inner tube and supports for the inner tube, said inner tube being of double walled construction filled with an insulating material wherein said supports for the inner tube include an electro hydraulic braking and positioning subsystem attached to the external wall of the inner tube that operates against an internal wall of the outer tube.
