[0024] In general, the present disclosure relates to an article of manufacture providing an O.sub.2 Tree for removing CO.sub.2 gas from the atmosphere according to the present invention. To better understand the present invention, FIG. 1 illustrates example embodiments of an article of manufacture providing a device for removing CO.sub.2 gas from the atmosphere according to the present invention. The O.sub.2 Tree 101 is a small device that is similar in size to a large individual permitting the O.sub.2 Trees to be located throughout a region inhabited by people. The O.sub.2 Tree 101 is intended to be installed nationwide throughout all cities, towns, and residential neighborhoods, operating 24/7 to filter out CO.sub.2 and deliver O.sub.2.

[0025] An O.sub.2 Tree 101 is a device designed to suck in air containing carbon dioxide (CO.sub.2), direct the captured CO.sub.2 to the earth, and output oxygen (O.sub.2) The O.sub.2 Tree 101 is built in a manner pleasing to the eye, and yet able to capture CO.sub.2 and output O.sub.2 at a far greater volume than real trees. The O.sub.2 Tree 101 may operate on AC power and in the event of AC power failure, a rechargeable battery may be used to provide power for continued operation until AC power is restored. In the event of extended AC power loss, the rechargeable battery powers the unit until battery power is depleted to 10%, at which point, the O.sub.2 Tree 101 powers down to allow the rechargeable battery to charge to 95%. Once the O.sub.2 Tree 101 reaches this threshold, the O.sub.2 Tree 101 powers up again. This CO.sub.2 extraction processing cycle repeats until AC power is restored. In this manner, the O.sub.2 Tree 101 ensures continued daily operation with off periods for battery recharging.

[0026] The O.sub.2 Tree 101 operates by drawing atmospheric air into the device 101 through an input port 121. The atmospheric air includes both O.sub.2 and CO.sub.2 gases as well as other elements. The O.sub.2 Tree 101 extracts the CO.sub.2 from the atmospheric air and passes the CO.sub.2 through a captured CO.sub.2 output port 123 to be mixed with water 125. The O.sub.2 gas and other constituent elements are expelled out a separate exhaust port 122. The water, having dissolved the CO.sub.2 gas contained therein, may be stored into rock formations 130 for long term storage. Additional details regarding the O.sub.2 Tree 101 are described below in reference to FIG. 2.

[0027] FIG. 2 illustrates another example embodiment of an article of manufacture providing an O.sub.2 Tree for removing CO.sub.2 gas from the atmosphere according to the present invention. The example embodiment of an O.sub.2 Tree 101 shown in FIG. 2 is constructed using an internal frame structure 102, a support base 103, a solar power dome 104, and a pair of treated air exhaust lines each having its own exhaust port 112a-b. The O.sub.2 Tree 101 further comprises a pair of rechargeable batteries 113a-b, a controllable exhaust valve 114, a CO.sub.2/O.sub.2 processing unit 115, a controllable intake valve 116, a pair of intake ports 117a-b, and a CO.sub.2 storage unit 118.

[0028] The internal frame structure 102 supports all of the components within the O.sub.2 Tree 101 as well as provides a path through the O.sub.2 Tree 101 as the CO.sub.2 is extracted from the air and processed for storage underground. The internal frame structure 102 also provides a path for the processed O.sub.2 gas to reach the external exhaust ports 112a-b for returning the processed O.sub.2 gas to the atmosphere.

[0029] The support base 103 is connected to the internal frame structure 102 to orient the O.sub.2 Tree 101 into a desired position. The support base 103 also may include connections to external devices including external power and wastewater containing the dissolved CO.sub.2 gas for storage.

[0030] The solar power dome 104 is a solar array support containing one or more solar array devices as shown in FIG. 4 that provide electrical power to recharge the rechargeable batteries 113a-b as well as provide a backup power source to power the O.sub.2 Tree 101 when AC power from an external source is unavailable. The solar power dome 104 may possess any shape that supports the solar arrays 414 and directs the solar arrays toward the sun as needed.

[0031] The pair of treated air exhaust lines 111a-b, each having its own exhaust port 112a-b, is connected to the controllable exhaust valve 114 to permit the processed gas to be vented out of the exhaust ports 112a-b into the surrounding environment.

[0032] The pair of rechargeable batteries 113a-b store electrical energy that may be used to power the O.sub.2 Tree 101 when external power in not available. The pair of rechargeable batteries 113a-b may be charged using the external power source when it is available and may be charged by the solar arrays 414 coupled to the solar power dome 104.

[0033] The controllable exhaust valve 114 opens and closes to permit the processed air to flow to the exhaust ports 112a-b. As disclosed in more detail in reference to FIG. 4, the atmospheric air is passed into the CO.sub.2/O.sub.2 processing unit 115 where the CO.sub.2 gas is captured. The controllable exhaust valve 114 is closed to permit the CO.sub.2/O.sub.2 processing unit 115 to vent the captured CO.sub.2 gas into the CO.sub.2 storage unit 118 for further processing for long term storage.

[0034] The CO.sub.2/O.sub.2 processing unit 115 accepts atmospheric air and captures the CO.sub.2 contained within the atmospheric air before venting the processed air through the exhaust ports 112a-b. The CO.sub.2/O.sub.2 processing unit 115 cycles through a set of operating modes as disclosed in detail in regard to FIG. 4. Once the CO.sub.2/O.sub.2 processing unit 115 has captured a sufficient amount of CO.sub.2 gas, the controllable exhaust valve 114 and the controllable intake valve 116 are closed and the captured CO.sub.2 gas may be processed and stored within the CO.sub.2 storage unit 118. Once the CO.sub.2 gas has been vented into the CO.sub.2 storage unit 118, the controllable exhaust valve 114 and the controllable intake valve 116 are reopened to begin another CO.sub.2 extraction processing cycle.

[0035] The controllable intake valve 116 controls the intake flow of atmospheric air from the environment through the intake ports 117a-b into the CO.sub.2/O.sub.2 processing unit 115. The CO.sub.2/O.sub.2 processing unit 115 cycles through a set of operating modes as disclosed in detail in regard to FIG. 4. Once the CO.sub.2/O.sub.2 processing unit 115 has captured a sufficient amount of gas, the controllable exhaust valve 114 and the controllable intake valve 116 are closed and the captured CO.sub.2 gas may be processed and stored within the CO.sub.2 storage unit 118. Once the CO.sub.2 gas has been vented into the CO.sub.2 storage unit 118, the controllable exhaust valve 114 and the controllable intake valve 116 are reopened to begin another CO.sub.2 extraction processing cycle.

[0036] The pair of intake ports 117a-b passes atmospheric air into the O.sub.2 Tree 101 in order to extract the CO.sub.2. The pair of intake ports 117a-b is coupled to the controllable intake valve 116 creating a path to the CO.sub.2/O.sub.2 processing unit 115. The CO.sub.2/O.sub.2 processing unit 115 cycles through a set of operating modes as disclosed in detail in regard to FIG. 4. Once the CO.sub.2/O.sub.2 processing unit 115 has captured a sufficient amount of CO.sub.2 gas, the controllable exhaust valve 114 and the controllable intake valve 116 are closed and the captured CO.sub.2 gas may be processed and stored within the CO.sub.2 storage unit 118. Once the CO.sub.2 gas has been vented into the CO.sub.2 storage unit 118, the controllable exhaust valve 114 and the controllable intake valve 116 are reopened to begin another CO.sub.2 gas extraction cycle.

[0037] The CO.sub.2 storage unit 118 is coupled to the CO.sub.2/O.sub.2 processing unit 115 to accept the vented CO.sub.2 gas for further processing and storage. Disposing of the vented CO.sub.2, may be accomplished in several ways. In a preferred embodiment, the vented CO.sub.2 gas is dissolved into water where it may be pumped into the ground to a depth of 26,561 feet, or 1.2 miles, where it naturally converts to carbonates. Another option is to capture the CO.sub.2 in a container that would be collected at regular intervals; a good option because CO.sub.2 is a useful product to other industries.

[0038] FIG. 3 illustrates the example embodiment with an outside enclosure of the article of manufacture providing an O.sub.2 Tree for removing CO.sub.2 gas from the atmosphere according to the present invention. The O.sub.2 Tree 101 shown in FIG. 3 includes a cylindrical casing 301 around all of the components described above in reference to FIG. 2. The cylindrical casing 301 includes an access door that may open 180 degrees to allow easy access to all components. The cylindrical casing 301 also protects individuals near the O.sub.2 Tree 101 as the CO.sub.2/O.sub.2 processing unit 115 requires heating the captured CO.sub.2 before venting the gas into the CO.sub.2 storage unit 118.

[0039] FIG. 4 illustrates a block diagram of an article of manufacture providing an O.sub.2 Tree for removing CO.sub.2 gas from the atmosphere according to the present invention. One embodiment of an O.sub.2 Tree 400 is constructed using an enclosed container 401 having a CO.sub.2 filtering chamber 402 with a fan 403 driven by a fan motor 421 to direct atmospheric air into an intake port 411 and through a filter element 404. The filter element 404 includes a specially developed absorbent which binds the CO.sub.2 from the air. For example, graphene filters are known to capture CO.sub.2 from the air.

[0040] The filtered air having the CO.sub.2 removed is expelled as exhaust out of an exhaust port 413. When the filter element 404 has captured the CO.sub.2, the intake port 411 and exhaust port 413 are closed. The CO.sub.2 filtering chamber 402 is heated by a heater element 422 to release the CO.sub.2 from the filter element 404 into the CO.sub.2 filtering chamber 402. A captured CO.sub.2 transfer port 412 may be opened and the fan 403 forces the CO.sub.2 into a CO.sub.2 storage unit 405. The captured CO.sub.2 transfer port 412 is closed before the intake port 411 and the exhaust port 413 are opened and the CO.sub.2 extraction processing cycle continues.

[0041] The O.sub.2 Tree 101 is powered by a power supply 420 that is coupled to an external source (not shown), the solar array 414, and one or more rechargeable battery 113a-b. As described above, the power supply 420 will typically operate using the external AC power. When the external source is not available, the rechargeable batteries 113a-b may provide power to operate the O.sub.2 Tree 101. The power supply 420 can recharge the batteries 113a-b using the external source when available and the solar array 414 when needed.

[0042] A controller 423 commands the operation of the components within the O.sub.2 Tree 101. The controller 423 sends control signals to the intake port 411, the exhaust port 413, the captured CO.sub.2 transfer port 412, and the fan motor 421 to operate and close as needed. The controller 423 engages the heater 422 during the CO.sub.2 extraction processing cycle to extract the captured CO.sub.2 from the filter 404. The controller 423 comprises an electronic device configured to control the operating state of the intake port 411, the exhaust port 413, and the captured CO.sub.2 transfer port 412, the fan motor 421, and the heater element 422 throughout the CO.sub.2 extraction processing cycle described above.

[0043] The CO.sub.2 storage unit 405 is coupled to the captured CO.sub.2 transfer port 412 by a transfer pipe 426 allowing the captured CO.sub.2 to pass to a water carbonizer 424. The captured CO.sub.2 is dissolved into water by the water carbonizer 424. This wastewater containing the CO.sub.2 is pumped by a water pump 425 to an external reservoir location through a number of water pipes 427-428.

[0044] After this, the wastewater transports the carbon dioxide to approximately 2,000 meters below the surface of the Earth. The dissolved CO.sub.2 is now left there to naturally convert to carbonates through various mineralization processes with the basalt rock.

[0045] Even though particular combinations of features are recited in the present application, these combinations are not intended to limit the disclosure of the invention. In fact, many of these features may be combined in ways not specifically recited in this application. In other words, any of the features mentioned in this application may be included in this new invention in any combination or combinations to allow the functionality required for the desired operations.

[0046] No element, act, or instruction used in the present application should be construed as critical or essential to the invention unless explicitly described as such. Further, the phrase “based on” is intended to mean “based, at least in part, on” unless explicitly stated otherwise.
