The Geothermal Wind System is a hybrid power production system using geothermal transfer of heat between native rock and an air mass circulating between two or more portals of substantially different vertical elevations by use of the stack effect and the buoyancy of heated air or gravity pulling cooled air to turn one or more wind turbines which drive one or more generators. This wind speed can be improved by use of a venturi valve in close proximity to the turbine(s). A novel example of an aerodynamic, adjustable radial venturi is also herein incorporated. Two modes of the GWS are herein described, one used at shallow depths having geothermal temperatures approximating the average exterior climate, and the second used with geothermal temperatures found at greater depths at substantially higher than outside temperatures. The GWS is a non-polluting, non-carbon burning, non-water-dependent power production system easily implemented in third world countries.
