Abstract: An energy transport and conversion system for conducting geothermal energy over extended distances without loss of the geothermal energy so as to permit efficient conversion of geothermal energy at a central thermal power station. The energy transport system includes multiple, geographically dispersed wells for preheating a fluid medium, multiple separate conduits for conducting the fluid medium to a common, central thermal power station separated from the geothermal wells by an extended distance and multiple concentrating solar collectors associated respectively with the separate conduits for heating the fluid medium as it moves through the conduits toward the central thermal power station and thereby preventing loss of geothermal energy during such movement despite the extended distance.
