Sub-Terranean Updraft Tower (STUT) Power Generator

A sub-terranean updraft tower power generation system, comprising:

• a combination subsurface Outer Downdraft Shaft/Inner Updraft Tower having an Outer Downdraft Shaft primarily located in a subsurface region of Earth, providing physical containment and environment for the base Outer Downdraft Shaft and structural foundation, and enclosure for Inner Updraft Shaft, an Inner Updraft Shaft located within the Outer Downdraft Shaft, with Outer Downdraft Shaft air/gas inlets of located at above ground surface level and receiving air into Outer Downdraft Shaft vertical airflow downward from Outer Downdraft Shaft Air Inlets located at the upper, above grade perimeter, providing a continuous 360 degree opening for air intake of the Outer Downdraft Shaft, with said Outer Downdraft Shaft providing geothermal cooling effect and/or normalization conditioning of air/gas entering the air Outer Downdraft Shaft, maintaining control of, and sustaining, stable air temperatures of air mass flowing into and through Outer Downdraft Shaft, with air mass arriving at the Transition Airflow Zone at the bottom of the Outer Downdraft Shaft Inner Updraft Shaft receiving upward air flow from lower Outer Downdraft Shaft Airflow Transition Zone, initiating and achieving the functions of temperature differential, pressure differential, and volumetric displacement, with said Inner Updraft Shaft, and Updraft Shaft lining providing containment, mixing, and transfer of the conditioned & displaced airflow mass, received from the Transition Airflow Zone, mixing with heat resources injected into the system within the Inner Updraft Shaft, sustaining buoyant gas/air mass displacement and heated air flow upward into Vertical Axis Vertical Airflow (VAVANT) Nozzle, with said Inner Updraft Shaft lining, truncated cone, or vertical hollow conical frustum, with flared end downward and tapered end upward, decreasing in diameter as the Inner Updraft Shaft approaches the VAVANT Airflow Nozzle and Turbine orifice, being a partition between the Outer Downdraft Shaft and Inner Updraft Shaft within the subsurface regions of the system orientation, having the effect of constraining air flow velocity, and air volume, while increasing pressure within upper elevations of the Inner Updraft Shaft as well as overall system pressure differential;
• and
• an Upper Updraft Shaft and Tower, that provides for system air discharge, containing a plurality of Air Discharge vents, louvers and covers which protect the system from debris and foreign material entry, with the specific function characteristics and unique dimensional profile of the Upper Updraft Shaft being derived from the downwind airflow dispersion of the previously stated Beltz Ratio Flow Rate Relation, this updraft downwind zone of reduced airflow rate and low pressure zone is the means of accounting for, and reducing back pressure and turbine blade wake turbulence, the Upper Updraft Shaft enhances overall system pressure differentials, but providing communication of relatively high-pressure air mass located within the VAVANT Nozzle, with the relatively low-pressure air mass, located externally;
