Description

[0001] S I MYU01-24-25

[0002] This disclosure relates, inter alia, to system and method for energy extraction and generation of electricity from air pressure difference.

[0003] Electricity is the most commonly used form of energy. Most of the energy needs are addressed through coal and oil, which contribute to global warming. Current clean energy solutions such as solar photovoltaic energy and wind energy may become a part of the solution but have significant drawbacks. For example, electricity generation using solar photovoltaic energy and wind energy is location specific, requiring the generation of electricity at distant locations and transmission and distribution of power to consumer. This leads to power losses during transmission and distribution. Moreover, solar photovoltaic energy and wind energy are not consistently available, and power generation is not guaranteed all the time. For example, solar photovoltaic energy may be used only during day time. Similarly, the location of the wind mill, direction and intensity of wind matters. This unpredictability requires electricity storage in the form of grid or batteries. This leads to more capital cost and operational cost. In addition, energy is lost during storage and retrieval, reducing the efficiency of the overall system. For wind and solar photovoltaic energy, power generation occurs for only few hours of the day, hence returns on capital investment are poor and break-even occurs in typically 5 years or more. For example, useful solar energy for solar photo voltaic technology is available for only average 4 hours per day in some countries and whole system is idle for rest of the 20 hours. Moreover, the space requirements of solar and wind technologies are huge. Therefore, novel approaches for the generation of clean energy are required.

[0004] Accordingly, the present disclosure relates to system and method for energy extraction and generation of electricity from air pressure difference.

In some embodiments, the system comprises: i) a Fluid Chamber (1) comprising a column of a fluid, ii) a Vacuum Chamber (3) comprising a vacuum, wherein the Vacuum Chamber (3) is disposed on top of the Fluid Chamber (1) or placed nearby Fluid Chamber (1) and iii) an Energy Chamber (2), characterized to be fully contained inside the Fluid Chamber (1). In some embodiments, the walls of the Vacuum Chamber (3), the Energy Chamber (2) and the Fluid Chamber (1) are made of a non-magnetic material (e.g., non-magnetic stainless steel, brass or a polymer). In some embodiments, the Vacuum Chamber (3) is connected to the Fluid Chamber (1) via a valve. In some embodiments, the valve is a solenoid valve. In some embodiments, the fluid is water.

[0010] Chamber (1) by a magnetic force between the top magnets (4) at the top of the Fluid Chamber (1) and magnets and objects that are attracted to a magnet of the Energy Chamber (2).

[0011] In some embodiments, the Fluid Chamber (1) further comprises a plurality of position sensors. In some embodiments, the Fluid Chamber (1) comprises at least two position sensors. In some embodiments, the position sensors are substantially uniformly distributed along the height of the Fluid Chamber (1).

[0012] In some embodiments, the Energy Chamber (2) further comprises: one or more objects detectable by the position sensor that are stationary with respect to the Energy Chamber (2); and an object detectable by the position sensor that floats or is float-able on the fluid.

[0018] In some illustrative embodiments, when the Energy Chamber (2) weighs 2500 N acting downward and buoyancy force acting on it is 10000 N upwards (for 1 cubic meter size Energy Chamber (2)), the net upwards force when Energy Chamber (2) is completely filled with air is (10000- 2500)=7500 N. In these embodiments, the magnetic force exerted by bottom magnets (5) is just below 7500 N, such as 7000 N, that will ensure that Energy Chamber (2) is completely filled with air before it starts moving upwards to generate power stroke.

[0019] In some embodiments, the top magnets (4) have a magnetic force sufficient to hold Energy Chamber (2) in top most position, until it is completely filled with fluid.

[0020] In some embodiments, the magnetic force exerted by the top magnets (4) is about 85%, or about 90%, or about 93%, or about 95% of the maximal weight force that is exerted by Energy Chamber (2) when it is completely filled with fluid.

[0021] In some illustrative embodiments, when weight of the Energy Chamber (2) itself is 250 Kg, downward force acting on it when completely filled with fluid is 2500 N, assuming acceleration due to gravity (g) is approximately 10 m / s2In these embodiments, the magnetic force acting on it is less than 2500 N, like 2000 N, it holds back Energy Chamber (2) until it is completely filled with fluid.

S I MYU01-24-25

[0039] As atmospheric air, undergoes expansion from 1 bar to various lower pressure values, (like 0.62 bar, 0.688 bar etc.), thermodynamic work is done. For example, case no 1, as atmospheric air expands from 1 bar to 0.62 bar, 43.71 joules of thermodynamic work is done in one second & power of this system is 43.71 watts. This thermodynamic work is converted into mechanical work when Energy Chamber (2) moves upwards and linear generator system converts this into electrical work. This thermodynamic work used to generate electricity as Energy chamber (2) moves up, remove air out of the Energy Chamber (2) by replacing air with Fluid and generate electricity as Energy Chamber moves downwards.

[0040] Aspen Hysys calculates the work of air expansion between two pressures, Pl (Inlet) and P2(Outlet), using thermodynamic principles based on the selected property method (e.g., ideal gas or real gas equations of state). Hysys calculates the required physical properties such as Cp and Cv etc. using appropriate property correlation. For air modelled as an ideal gas, the expansion work depends on whether the process is isothermal, adiabatic, or polytropic. Aspen determines enthalpy and entropy changes from its property database and integrates these with the specified process path. Aspen Hysys does not assume a fixed path unless specified; it calculates state properties at each pressure using rigorous thermodynamic models (e.g., Peng-Robinson, SRK) and integrates work from these states. For real gases, deviations from ideal-gas are handled through fugacity and compressibility factors, ensuring accurate work prediction for expansion.

[0041] A large number of simulations were carried out using Aspen Hysys by varying the air flow rate and the downstream pressure P2, as summarized below. These simulations have been tested and verified in the experimental set-up and the findings are presented below. S I MYU01-24-25

[0044] This experiment shows, in the state 1 , Fig 2. even though air enters the bottom of the fluid chamber, its vacuum is not lost and relative pressure remains constant as shown in the graph below. This is due to arrangement of the Energy Chamber (2) placed specifically inside Fluid Chamber (1) capturing all the air entering inside Fluid Chamber (1). For example, accumulated air of 1.46 liter has entered the fluid chamber but relative pressure of (-0.8) remains constant.

The Vacuum Pump (17) starts and runs until a very low vacuum of 0.1 bar is created inside the Vacuum Chamber (3) and at the top of the Fluid Chamber (1) equivalent to the Energy Chamber (2)’s volume. Once a vacuum of 0.1 bar or less is sensed by PLC using a pressure sensor inside Vacuum Chamber (3), the Vacuum Pump (17) is powered off. The vacuum is maintained below 0.1 bar, even though the Vacuum Pump (17) is switched off. The Vacuum Pump (17) is typically not turned on again, outside the initial state during normal operation.

[0100] Once the system is made operational, the system transitions sequentially from one state to another (states 1 to 9) to complete one cycle. At the end of the cycle, the system is back in its initial state and the next cycle with state 1 can start again.

[0101] FIG. 2. shows “State 1 i.e. Start of Air Entry into Fluid Chamber (1).” In various embodiments, the pressure inside Vacuum Chamber (3) is less than 0.1 bar and Vacuum Pump (17) is switched off, level sensor B inside Energy Chamber (2) indicates fluid level at the topmost position inside Energy Chamber (2), and level sensor A shows Energy Chamber (2) is positioned at the bottom. S I MYU01-24-25

[0102] Solenoid Valves (7b) (7c) opens. Air flows into the Fluid Chamber (1) first due to the pressure difference (for example 1 bar atmospheric pressure vs. approximately 0.5 bar at the fluid column bottom for 5 meters when fluid is water), fluid level inside the Fluid Chamber (1) rises in proportion to the volume of the air moved in. All the air that enters via Solenoid Valve B (7b) enter into fluid, this air flows upwards, under buoyancy force, only towards Energy Chamber (2) strategically placed directly above the Solenoid Valve B (7b) opening.

[0103] FIG. 3 shows “State 2: Gradual Air Filling Inside Energy Chamber (2)” In various embodiments, air flows into the Energy Chamber (2) and reaches the top of the Energy Chamber (2), where its upward movement stops due to stationary Energy Chamber (2). Buoyancy force pushes air-filled Energy Chamber (2) upward, but it’s held in place by Bottom magnet (5). Level Sensor B starts detecting displacement of fluid inside Energy Chamber (2) by air, and Level Sensor A shows Energy Chamber (2) is positioned at the bottom. No valve position is changed by PLC but it monitors level sensor B closely to make sure Energy Chamber (2) is completely filled with air.

[0104] FIG. 4 shows “State 3: Energy Chamber (2) Release Upwards.” In various embodiments, level sensor B inside Energy Chamber (2) monitors the fluid level inside Energy Chamber (2). Once Energy Chamber (2) is completely filled with air, Level Sensor B (6b) indicates that the fluid level inside Energy Chamber (2) has reached the bottommost position System Hardware (19) commands turning off the Solenoid Valve B (7b) and solenoid valve C (7c). At this stage buoyancy force on air-filled Energy Chamber (2) exceeds the magnetic force of Bottom magnet (5). This causes Energy Chamber (2) to be released from the bottom position inside Fluid Chamber (1) with upward force.

[0105] FIG. 5 shows “State 4: Energy Chamber (2) Movement Upwards - Power Stroke.” In various embodiments, level sensor B inside Energy Chamber (2) monitors the upward movement of the Energy Chamber (2). EC Guides (11) inside the Fluid Chamber (1) smoothly facilitate the upward movement of Energy Chamber (2). The upward motion of Energy Chamber (2) is the power stroke and energy generated during upward motion drives an alternator or generator. Any mechanism that converts linear motion to electrical power generation is used here. The amount of power generated will be directly proportional to the volume of the Energy Chamber (2) used.

[0106] FIG. 6 shows “State 5: Start of Air Exhaust from Energy Chamber (2).” In various embodiments, Energy Chamber (2) docks into the topmost position as it is stopped by the upper Energy Chamber S I MYU01-24-25

[0107] (2) stopper. Solenoid Valve A (7a) & solenoid valve D (7d) are turned on, allowing water to replace air inside Energy chamber (2) and air start to move back into Atmosphere (23). Top magnet (4) prevents the Energy Chamber (2) from moving downwards as the air removal is in progress.

[0108] FIG. 7 shows “State 6: Gradual fluid Inflow inside Energy Chamber (2).” In various embodiments, as air inside Energy Chamber (2) escapes to the atmosphere, fluid above the Energy Chamber (2) starts to move down to occupy the space. Gravity force starts pushing Energy Chamber (2) down, but it’s held in place by Magnet A. level sensor B starts detecting inflow of fluid inside Energy Chamber (2).

[0109] FIG. 8 shows “State 7: Energy Chamber (2) Release Downwards.” In various embodiments, PLC monitors Level Sensor B (6b) continuously to ensure complete removal of air from Energy Chamber (2). When all the air inside Energy Chamber (2) is removed back to the Atmosphere (23) and the fluid level inside reaches the top of the Energy Chamber (2), Solenoid Valve A (7a) & solenoid valve D (7d) is closed immediately by PLC. At this stage the gravity force on Energy Chamber (2) exceeds the magnetic force of Top Magnet (4). This causes Energy Chamber (2) to be released from the top position inside Fluid Chamber (1) with a downward force. Solenoid Valve A (7a) & solenoid valve D (7d) is closed at this stage based on input from Level Sensor B (6b) inside Energy Chamber (2).

[0110] FIG. 9 shows “State 8: Energy Chamber (2) Movement Downwards.” In various embodiments, Bottom Magnet (5) holds the Energy Chamber (2) in place initially but doesn’t have enough force to stop it from moving down once the Solenoid valve A (7a) is closed. This movement can also generate power if the Energy Chamber (2) weight is substantial. This state ends when Energy Chamber (2) is stopped by the bottom stoppers (16b) on the Energy Chamber (2) guide.

[0111] FIG. 10 shows “State 9: Energy Chamber (2) Movement Downwards continues.” In various embodiments, until it reaches bottom position where it is held in position by Bottom Magnets (5).

[0112] FIG. 11 shows “State transition diagram” how the overall system moves from one state to another state during the course of one cycle. This cycle repeats as the system enters from state 9 back into state 1 where it starts its fresh cycle of “air in”. During the whole operation it is important that the system does not lose vacuum at all and the Vacuum Pump (17) is operated only once. PLC monitors each state based on inputs to determine the current state and transition into the next state as shown in the diagram after receiving the appropriate trigger. S I MYU01-24-25

[0113] FIG. 12, shows the system begins in a single initial state. It can move between nine total states from state 1 to stat 9. Each transition is triggered by an event, input, or condition observed by sensors.

[0114] Initial State — If vacuum inside Vacuum Chamber (3) is less than 0.1 bar as indicated by Pressure sensor (20) system transitions to STATE 1 otherwise it waits for vacuum level to drop below 0.1 bar.

[0115] STATE 1: Turn on valve Solenoid Valve B (7b) and Solenoid Valve C (7c). Air starts entering Fluid Chamber (1).

[0116] STATE 2: Level Sensor (6b) inside Energy Chamber (2). As air reaches Energy Chamber (2) and starts filling Energy Chamber (2), fluid level starts to drop inside Energy Chamber (2).

[0117] STATE 3: Energy Chamber (2) is completely filled by air as indicated by level sensor (6b) turns off valves Solenoid Valve B (7b) & Solenoid Valve C (7c)

[0118] STATE 4: Level sensor (6a) as Energy Chamber (2) travels upwards. All-important power stroke, Linear alternator (25) generates power using this movement.

[0119] STATE 5: Energy Chamber (2) reaches topmost position as observed by Level Sensor (6a), Open Solenoid valves (7a) & (7d) let out the trapped air to replace air from Energy Chamber (2) with fluid.

[0120] STATE 6: Level sensor (6b) as fluid starts filling up Energy Chamber (2) replacing air.

[0121] STATE 7: Once the Energy Chamber (2) is completely filled with fluid Level sensor (6b) turns off Solenoid valves (7a) & (7d),

[0122] STATE 8: As Energy Chamber (2) starts travelling downwards. Linear Alternator (25) generates power.

[0123] STATE 9: Level sensor (6a) indicates Energy Chamber (2) reaches bottommost position.

[0124] After STATE 9, system transitions back to STATE 1 and continues. S I MYU01-24-25

Air enters (30) Fluid chamber (1) from atmosphere (23) into air inlet (10) when solenoid valve (7b) and solenoid valve (7c) are opened. Then Air enters (22) Energy chamber (2). Level sensors & transmitter (6a) and (6b) help track position of the Energy Chamber (2) and level of the fluid inside Energy Chamber (2), EC stopper A (16a) makes sure Energy Chamber (2) stops at the pre-defined position when Energy Chamber (2) travels upwards. When Energy Chamber (2) is in top most position, it is held in this position by Top Magnets (4) until sufficient air is not removed from Energy Chamber (2). Also, when Energy Chamber (2) travels downwards, EC Stopper B (16b) ensures that Energy Chamber (2) rests at the bottommost designated position. Energy Chamber (2) is held in this bottom most position by bottom magnet (5), until sufficient air is not filled into Energy Chamber (2) before it starts travelling upwards. When in topmost position and Energy Chamber (2) is filled up with air, solenoid valves (7a) and (7d) are opened and air inside Energy Chamber (2) is replaced by fluid. Air moves out from flexible air pipe (8), air outlet (9) back into atmosphere.
