A geothermal power generation system employs a primary power turbine & generator for power generation using geothermal heat provided by the geothermal resources pumped out of the production well, and a secondary power generation turbine & generator set for power generation using geothermal resources (such as water) being returned to the ground via the injection well. In some embodiments, the pressure of water is increased before it is pumped back into the injection well where it falls down through gravity (free falling gravity). Thus high pressure water (where water is pumped to high pressure) and/or geothermal water falling freely due to gravity (gravity free falling where water is released to fall by gravity) into the injection well is used to generate secondary power employing one or more micro-turbines that ate located (held by a chain or belt) inside the injection well. Thus, using the geothermal resources (primarily water, some gas optionally and perhaps some steam) being pumped back into the injection well, secondary power is generated and captured using the secondary power generation turbine & generator set in the injection well.
