DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

[0045] In general, the invention leverages mechanical advantages and functional synergies derived from a combination of laws of physics and engineering principles. The STUT Process uses a deep Outer Downdraft Shaft 14 in the earth, which houses an Inner Updraft Shaft 20, both contained within the subterranean regions of the system. These elements provide the structure that creates the opportunity for the mass displacement of air, to first move or flow downward into the Outer Downdraft Shaft 14, and then upward in the Inner Updraft Shaft 20. The use of a large diameter shaft that is at a lower elevation that surrounding the terrain creates initial thermal sink and cooling of the Outer Downdraft Shaft 14, and a natural or organic relative pressure differential within the STUT System 14, within the Outer Downdraft Shaft 14; as the air inside the shaft, at depth is at a relatively higher pressure than the air that is at ground level, due to the gravity constant.

[0046] A plurality of volumetric displacements of air or other gases communicate with other volumetric displacements of air or other gases, are sustained and continuously driven by the plurality of sustained pressure biases within the system. The pressure differential is also sustained and enhanced by temperature differentials that are initiated, sustained, and enhanced based on the orientation and configuration of STUT functional process elements. The STUT process includes an Inner Updraft Shaft 20 vertical air shaft with nozzled turbine assembly, oriented and housed within a deep sub-terrestrial Outer Downdraft Shaft 14, receiving low velocity air flow from outer air-inlets at ground surface level 26, downward into a deep Outer Downdraft Shaft 14. Once reaching the bottom of the Outer Downdraft Shaft 14, air flow reverses in direction, inward and upward, into the inlet of the Inner Updraft Shaft 20 STUT shaft. STUT airflow is induced and sustained via the injection of air and heat 55 into the contoured Inner Updraft Shaft 20 of the STUT, creating coherent, accelerated airflow, that approaches the contoured Vertical Axis Vertical Airflow Nozzle and TurbineVAVANT Airflow Turbine 31 with relatively increased pressure and velocity; causing divergent, convergent airflow to pass through and within the contoured nozzle, and across the VAVANT Airflow Turbine 31. The summation of pressure biases in the Outer Downdraft Shaft 14, and Inner Updraft Shaft 20 and VAVANT Airflow Nozzle 30 drives accelerated airflow toward the face of the turbine, causing rotation of the VAVANT Airflow Turbine 31, and the summation of torque forces at VAVANT Airflow Turbine 31 hub and perimeter, attached gearing, and power head 33, thus generating EMF and electrical power.

[0047] The processes of initiating, inputting, gathering, collecting, controlling, aligning orienting, conditioning, accelerating, transferring, exchanging, and mixing airflow mass with available heat into the airstream, optimizing exergy, and harnessing converted power from this technology is the focus and accomplishment of this invention. These and the other main STUT elements provide the following processes related to STUT System 14 Organization and Operations, that support or provide beneficial functions and associated features described herein, according to the present invention.

The Sub-Terranean Updraft Tower Process Organization

[0048] The STUT System 14 has several key functional processes and elements which, according to the present invention, include: [0049] a. Air Resource [0050] b. Heat Resource [0051] c. Downdraft Air Inlet [0052] d. Outer Downdraft Sub-Terrestrial Shaft [0053] e. Inner Updraft Shaft [0054] f. VAVANT Airflow Turbine [0055] g. VAVANT Nozzle [0056] h. Upper Updraft shaft [0057] i. System Command & Controls

[0058] The Outer Downdraft Sub-Terrestrial Shaft provides the physical containment and environment for the base and structural foundation of the STUT Tower 24. The Outer Downdraft Shaft Lining 17 is made of concrete, steel, or other rigid impermeable material; shaft depth and diameter are included among the contributors to the power generation capacity factors of the STUT process. Outer Downdraft Shaft Air Inlets 11 Ports & Dampers, control incoming air flow 12 into the Outer Downdraft Shaft 14 are provided by a continuous 360 degrees opening of air intake apparatus, located at the upper, above grade perimeter of the Outer Downdraft Shaft 14. The Outer Downdraft Shaft 14 houses an airflow control apparatus including dampers, louvers, openings, screen mesh, etc., and are located at, near, and/or above ground surface level 26. The Outer Downdraft Shaft 14 provides partial geothermal cooling of warm/hot air entering the shaft and is partially insulated, to counter the geothermal temperature gradient, in order to maintain control of, and sustain, relatively low or cool air temperatures of air mass flowing into and through the Outer Downdraft Shaft 14, regardless of climate or season. Both functions of Temperature Differentials and Pressure Differentials are initiated within the Outer Downdraft Shaft 14, with air mass arriving at the Transition Airflow 15 Zone 16, located at the bottom of the Outer Downdraft Shaft 14, cooler, denser, and of higher pressure than when it entered the Outer Downdraft Shaft 14.

[0059] The Inner Updraft Shaft lining 27 provides containment, mixing, and transfer of the conditioned airflow mass received from the Transition Airflow 15 Zone 16, at the bottom of the Outer Downdraft Shaft 14. It contains the Heat Exchanger 23 function and VAVANT Airflow Nozzle 30 and Turbine 31, and is housed or located within the Outer Downdraft Shaft 14. The Inner Updraft Shaft 20 is a cowling, made of a strong, lightweight, impermeable material that partitions the Outer Downdraft Shaft 14 zone, and Inner Updraft Shaft 20 zone within the subsurface 18 regions of the system. The Inner Updraft Shaft 20 is a hollowed, truncated cone, or vertically oriented hollow conical frustum, with flared end downward, and tapered end upward, decreasing in diameter as the Inner Updraft Shaft 20 rises, approaching the VAVANT Airflow Turbine 31 orifice. This orientation has the effect of constraining air flow velocity, slightly decreasing air volume, while increasing pressure within the Inner Updraft Shaft 20, and the overall system pressure differentials.

[0060] As air approaches the VAVANT Airflow Turbine 31 orifice, it is at a relatively higher pressure than the ambient air pressure external to the system, or that is in the Outer Downdraft Shaft 14, or air that is in the Upper Updraft shaft 20 located above and downwind of the VAVANT Airflow Turbine 31 orifice. The VAVANT Airflow Nozzle 30 is part of the Inner Updraft Shaft 20 and functions to divert or spread, producing a 360-degree diversion of the vertical airflow stream, which is created within the Inner Updraft Shaft 20, into the VAVANT Airflow Turbine 31 inlets. The VAVANT Airflow Nozzle 30 has decreased the cross-sectional area of air flow, which increases the relative pressure, flow rate as the diverted, diverged air approaches the VAVANT Airflow Turbine 31 orifice. This VAVANT Airflow Turbine 31 orifice is a ring configuration, similar to the preferred, outer ring of performance within the outer edges, or radius of a typical Horizontal Axis Wind Turbine-HAWT Swept Area; not the less preferred single center opening that directs airflow onto turbine blades that occupy the center, lowest performing regions of a typical Horizontal Axis Wind Turbine-HAWT Swept Area. In addition to air, heat is the additional primary energy input into the STUT System 14. Heat 50 is brought into the system via heat exchangers 23 and working fluid from Heat Resources Options 54, derived from a plurality of heat resources, into the Inner Updraft Shaft 20. Achieving the previously described Outer Ring of Performance forms the basis of the function and orientation of the VAVANT Airflow Nozzle and Turbine, and supporting combination Downdraft/Updraft Tower of the STUT process, and is the primary focus of this invention.

[0061] The VAVANT Airflow Turbine 31 makes use of the Upward Air Flow and associated mass flow rate generated within the Inner Updraft Shaft 20. The STUT uses an air flow turbine seated at the apex of the Nested Converging-Diverging Semi-Ovular Nozzled 32 orifice and harnesses energy from the Heated Up Airflow 25 moving through the Inner Updraft Shaft 20 and VAVANT Airflow Nozzle orifice. VAVANT Airflow Nozzle 30 and Turbine 31 is made of light weight, high strength, durable materials that are connect via center located power shaft and mechanical gearbox. In an alternative configuration multiple power heads 33 are located at the perimeter of the VAVANT Airflow Turbine 31 Outer Ring, via mechanical power shaft apparatus. A plurality of VAVANT Airflow Turbine 31 related mechanical, electrical, electronic control, monitoring, and mechanisms are housed within the VAVANT Airflow Nozzle 30 to efficiently and reliably harness the airflow energy, and its conversion to mechanical, and electrical power output 37.

[0062] With STUT, a large and deep shaft of air will have greater mass and significantly higher relative air pressure than that at ground level. The relationship of the Inner Updraft Shaft 20 and Outer Downdraft Shaft 14 are unique and significant because their designed orientation create a constant taper effect of air volume as it air approaches the VAVANT Airflow Nozzle 30 and Turbine 31. This orientation creates a continuous decrease of the cross-sectional area as the air moves downward in the Outer Downdraft Shaft 14 and then upward within the Inner Updraft Shaft 20. The outer shaft is a true cylinder while the Inner Updraft Shaft 20 is a truncated cone, or conical frustum, with the taper down or decreasing diameter end closest to the VAVANT Airflow Nozzle 30 and Turbine 31. In this case, as air crosses the turbine and enters the Upper Updraft shaft 20, it slows dramatically. STUT enhances this natural stack effect by injecting heat the Upper Updraft shaft 20. This higher temperature, compared to the air temperature of the Inner Updraft Shaft 20, creates a pressure and volume difference. As the air approaches the exit opening or nozzle of the Inner Updraft Shaft 20, and crosses the VAVANT Airflow Turbine 31 orifice, the Venturi effect, caused by the orientation and configuration of the Nested Converging-Diverging Semi-Ovular Nozzled 32, causes mass flow rates and air velocity to increase, dramatically, at the ringed orifice.

[0063] The VAVANT AirFlow Nozzle 30 and Turbine 31 orifice of this System is not a single center hole that passes air in a single center-lined air stream, rather it is a shaped, contoured orifice is created by the use of a combination flared valve nozzle, that (produces a ring) passes high-speed air, at flow rates sufficient to the spin turbine. The actions or functions of the enhanced pressure differential across the orifice; per the Combined Gas Law, the achieved, pressure bias of the Upper Updraft shaft 20 and the Inner Updraft Shaft 20; Airflow, Volume displacement, and/or mass flow rates are directly proportional to the input/output ratio of the VAVANT Airflow Nozzle 30 and Turbine 31 orifice. This orientation has the effect of decreasing air volume. However the system experiences a significant increase in airspeed, according to the Bernoulli Equation. The Bernoulli Equation and Venturi Effect teaches that increased velocity is achieved at the choke point or apex of constrained fluid flow; the resultant pressure drop associated with deceleration of mass displacement across turbine blades. The VAVANT Airflow Nozzle 30 provides the function of constraining mass flow, increasing pressure and accelerating velocity and mass flow rates through the nozzle and across the VAVANT Airflow Turbine 31. The narrowing diverging and converging of the orifice creates an orifice ring, harnesses the outer radius of Swept Area, and creates a performance ring that, unlike HAWT, that are designed across a range of air velocities, performs at a specific, controlled, tuned, optimized extremely high mass flow rate. The ideal system conditions leverage the variables of Pressure, Temperature, and Volume to create maximum pressure bias at the apex of the VAVANT Airflow Turbine 31, in accordance with the combined gas law; with the zone just above and downstream of the orifice possessing the lowest relative pressure within the system. The Upper Updraft shaft 20 also provide for system air discharge and holds the STUT Air Discharge vents 41, louvers and covers which protects the system from debris and prevents foreign items from falling in the STUT from above. Establishing and sustaining a plurality of STUT System 14 pressure biases, creates and sustains high mass flow rates; which are included among the key contributors to the power generation capacity factors of the STUT System 14.

[0064] The designed diameter ringed orifice, nested VAVANT Airflow Nozzle configuration, and its cross-sectional area are included among the contributors to the power generation capacity factors of the STUT System 14; providing mass flow rates sufficient to create torque equal to larger traditional HAWT. STUT is a VAVANT Airflow Turbine 31, which creates, controls, and uses this High RPM, medium torque device to produce electrical power equal to HAWT, more efficiently in a smaller footprint.

[0065] The Upper Updraft Shaft's 20 specific function characteristics and profile are derived from the downwind airflow dispersion of the Beltz Ratio Flow Rate relation schematic, sourced from Sustainable Energy, (Tester, Drake, etc.). Within the STUT System 14, this updraft downwind zone of reduced airflow rate and low-pressure zone must be accounted for to reduce back pressure and turbine blade wake turbulence. The Upper Updraft Tower provides the crucial element of, and dimension for downwind air disbursement needed in any wind turbine, but especially with a non-organic wind turbine with STUT unique orientation. The Upper Updraft Shaft Lining 45 is a cowling made of strong, lightweight, impermeable material that evacuates system air from STUT downwind chamber. Additionally, the Upper Updraft shaft 20 enhances overall system pressure differential, but providing communication of relatively high-pressure air mass with relatively low-pressure air mass, across the VAVANT Airflow Nozzle 30 and Turbine 31 orifice. The height and volume of the Upper Updraft Shaft 20 are included among the contributors to the power generation capacity factors of the STUT System 14. The Upper Shaft Vents system airflow and Covers 44 the STUT components.

[0066] As stated, the primary Heat Resource Option 54 for STUT in a Thermo-Electric Power Plant Hybrid configuration, is Power Plant waste heat 51. The preferred configuration is a full STUT, a non-hybrid configuration wherein Heat Resources 50 of Geothermal 52 Hot Dry RockHDR wells or Solar Thermal 53 Heat are utilized to provide fully renewable and emissions-free power generation to the Power Grid 56.

Operations of the Sub-Terranean Updraft Tower System

[0067] In accordance with the invention, there is provided a process that includes a Sub-Terrestrial Updraft Tower-STUT, which is a combination Downdraft/Updraft Tower airflow processes, that generates electrical power from the large volumetric displacements of air or other gases; driven by a plurality of sustained system pressure biases, and fed by temperature differentials that are initiated, sustained, and enhanced due of the configuration and orientations of the functions of numerous STUT process elements. The STUT process includes an Inner Updraft Shaft 20 vertical air shaft with nested Vertical Axis Vertical Airflow Nozzle and TurbineVAVANT Airflow Turbine 31 assembly. The Inner Updraft Shaft 20 is oriented and housed within a deep, sub-terrestrial Outer Downdraft Shaft 14 which receives low-velocity downdraft air flow 13 from STUT System 14 Outer Downdraft Shaft 14 air inlets located at or near ground surface level 26; with airflow downward into a deep Outer Downdraft Shaft 14.

[0068] Once reaching the bottom of the Outer Downdraft Shaft 14, air flow reverses in direction, inward and upward, into the Inner Updraft Shaft Inlet 21 of the Inner Updraft Shaft 20 of the STUT. The STUT Up Air Flow 22 is induced and sustained via the injection of air into the Outer Downdraft Shaft 14, and heat into the contoured Inner Updraft Shaft 20 of the STUT, which creates a coherent and accelerated airflow; and approaches the contoured Vertical Axis Vertical Airflow Nozzle and TurbineVAVANT Airflow Turbine 31 with relatively increased pressure and velocity; causing divergent converged airflow to pass through and within the contoured nozzle, and across the VAVANT Airflow Turbine 31 with high velocity and mass flow rate. The accelerated airflow causes rotation of the VAVANT Airflow Turbine 31, and the summation of torque forces present at the VAVANT Airflow Turbine 31 center hub and perimeter; within the attached gearing and power head 33; thus generating EMF and electrical power. The processes of initiating, inputting, gathering, collecting, controlling, aligning, orienting, conditioning, accelerating, transferring, exchanging, and mixing airflow mass with available heat into the airstream, optimizing exergy, and harnessing converted power from this technology is the focus and accomplishment of this invention. These and other major elements STUT provide the following processes related to STUT System 14 Organization and Operations, that support or provide beneficial functions and associated features described herein, according to the present invention.

[0069] STUT uses a larger diameter Outer Downdraft Shaft 14 to house and enclose a smaller diameter STUT Inner Updraft Shaft 20. STUT's unique design, utility, & orientation creates a combination Outer Downdraft Shaft 14/Inner Updraft Shaft 20 that cools & conditions a continuously descending air mass, creates a relatively lower temp, less buoyant air mass inside a subsurface 18 Outer Downdraft Shaft 14; and a higher temp, relatively more buoyant air mass inside a subsurface 18 Updraft Shaft/Tower 20. STUT uses the relatively large pressure differential between the surface and bottom of a deep shaft to charge the cooled air mass. STUT uses an Inner Updraft Tower/Outer Downdraft Shaft 14 transition to transfer downdraft airflow up and into STUT'sInner Updraft Tower; where the pressure differentials between the bottom of a deep STUT shaft/tower, and top of Upper Shaft 40 are optimized. The Upper Shaft 40 outlet vents 41 are located above ground surface, and at higher elevation/s than the Outer Downdraft Shaft 14 air inlet elevation/s and provides exit ports for outgoing air flow 42. This elevation or height delta between the bottom of Inner Updraft Shaft 20 and the top of Upper Updraft shaft 20 creates substantial pressure bias which is enhanced by the transfer or injection of heat 55 from Heat Resources 50, to locations within the inside of the Inner Updraft Shaft 20. With this established and sustained pressure bias, the relatively buoyant air mass of relatively higher pressure and temperature continuously moves into the low pressure zone within the upper shaft 40 with high velocity and mass flow rate. The air mass of relatively higher pressure and velocity steadily moves across the VAVANT Airflow Turbine 31, after accelerating and crossing or passing through the apex of a Nested Converging-Diverging Semi-Ovular Nozzled 34 (NCDSO), which is housed within the VAVANT Airflow Turbine 31 assembly.

[0070] STUT leverages the interdependence of the Pressure, Volume, and Temperature variables under the guidance of the Combined Gas Law, which states that: The ratio between the pressure-volume product and the temperature of a system remains or attempts to remain constant. This law as stated is interperted to say that with the existence of an imbalance of any one of the pressure, volume or temperature variables, one of the other variables will seek to re-establish a constant state of balance or equilibrium. STUT's processes and orientations of elements creates a configuration, containment, and environment of system conditions that establish and maintain system-wide pressure imbalances. between neutral pressure system locations, higher pressure system locations, and lower pressure system locations. Additionally, heat is introduced into the Inner Updraft Shaft 20 at depth, and drives the STUT System 14 Temperature differential into increased imbalance, creating a plurality of increased biases in Pressure and/or Volumetric displacement of air present in the system between Inner Updraft Shaft 20, Outer Downdraft Shaft 14, and Upper Updraft shaft 20. The high rate mass flow of air is harnessed by the VAVANT Airflow Turbine 31, as it attempts to reestablish ideal ratios and system balance. Sustaining this imbalance through the configuration and orientations of the functions of numerous STUT process elements creates controlled, stable, high volume, air flow displacement across STUT's VAVANT Airflow Turbine 31, to be harnessed as electrical power.

[0071] Per the Combined Gas Law, which is a gas law that is an amalgamation of three previously discovered and related laws, which combines Charles's law, Boyle's law, and Gay-Lussac's law. These laws each relate one thermodynamic variable to another mathematically while holding everything else constant. Charles's Law states that volume and temperature are directly proportional to each other as long as pressure is kept constant. Boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature. Finally, Gay-Lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume. The inter-dependence of these variables is shown in the combined gas law, which clearly states that:

[00001]$\frac{\mathrm{pV}}{T}=k$

The ratio between the pressure-volume product and the temperature of a system remains constant. This can be mathematically stated as, where:
p=pressure
V=volume
T=temperature
k is a constant (with units of energy divided by temperature).

Therefore

[0072] [00002]$\frac{p_1.Math.V_1}{T_1}=\frac{p_2.Math.V_2}{T_2}$

Within the STUT System 14, the plurality of Pressure, Volume, and Temperature combination variations and lack of equilibrium, once established within and throughout the system, feeds a continuous and sustained plurality of Pressure=p, Temperature=T, and Volume=V, or PVT non-equilibrium conditions. The Combined Gas Law equation chain, therefore, has a plurality of variable condition states as applied with STUT process, and therefore has applicability, continuity, and persistence throughout the STUT System 14, according to the present invention.

[0073] Comparing and/or seeking an equilibrium state with the performance of air under two or three different sets of conditions, or a plurality of system conditions and locations within the STUT System 14; the combined gas law, within a system with a plurality of locations and large volumetric conditions, can, according to the present invention, be extrapolated and or reinterpreted for a plurality of STUT System 14 conditions and locations; example L1, L2, L3, L4, etc., each with associated key variables of Pressure, Temperature, and Volume functions, expressed in FIG. 2 to be written as:

[00003]$\frac{p.Math.1.Math.V.Math..Math.1}{T.Math..Math.1}=\frac{p.Math.2.Math.V.Math..Math.2}{T.Math..Math.2}=\frac{p.Math.3.Math.V.Math..Math.3}{T.Math..Math.3}=\frac{p.Math.4.Math.V.Math..Math.4}{T.Math..Math.4}=\mathrm{etc}.$

[0074] According to the present invention, system elements and functions create conditions; wherein stability or equilibrium are sought but never achieved. A plurality of dynamic imbalance within the STUT System 14 induces and sustains communication of volumetric forces present within air masses at Locations L1 to L2, at L2 to L3, at L3 to L4, and so on, and so forth. An example of the plurality of relative system conditions is thus:

Such other features, modifications, and improvements are therefore considered to be a part of this invention, the scope of which is to be determined by the following processes.
