6] Referring now to FIG. I, a high-altitude structure 100 is depicted. High altitude structure 100 includes but is not limited to any of a variety of materials which may be relatively lightweight, strong, and be capable of standing aloft in a variety of atmospheric, weather-related, and heating conditions. Further, structure may be capable of being applied in a variety of environments and for a variety of applications. Structure 100 may be used in a variety of ways including as a supporting structure for equipment, such as but not limited to antenna 110, as a vent for exhaust gases 120, or as a particulate or gas introducer, or the like. In the example embodiment depicted in FIG. 1, structure 100 is an approximately cylindrical shape forming an elongated cannula having an exterior wall 130 surrounding an interior wall 140. In a particular example embodiment a void 150 may be formed between exterior wall 130 and interior wall 140. The structure may be supported by introducing a gas into void 150 which may be lighter than the ambient air surrounding the structure. Gas introduced into void 150 may come from any of a variety of sources. In a particular example embodiment, gas may come from a manufacturing facility 160 where gas may be manufactured for the purpose of supporting conduit 150 or the gas may be exhaust gasses from a manufacturing process at facility 160. in accordance with alternative embodiments, the structure of the voids and conduits may vary and may include any number of and combination of voids and conduits. Also, material flow in the voids and conduits may be controlled. In an alternative embodiment, there may be interconnections between the voids and conduits such that material flow may be created between the voids and conduits and/or between voids and/or between conduits. Although specific shapes, cross sections, and relative dimensions of the voids and conduits are depicted, the embodiments are not limited but may be made in any of a variety of shapes, cross sections, and relative dimensions.

Further, the shapes, sizes, materials, relative dimensions, etc., may vary by location on the structure or alternatively may be varied in time. In an example embodiment, the material flow may come from any of a variety of sources,

I

including but not limited to a reservoir, a storage container, the atmosphere, an exhaust or waste material flow, etc. [0027] High altitude conduit 100 is a conduit which may exceed the height of chimneys and like structures which are built from conventional building materials like concrete, steel, glass, wood, etc. which carry considerable weight. In one example embodiment conduit 100 may reach higher than one kilometer above its base. In other example embodiments the conduit may be formed to reach much greatet heights. For example, referring to FIG 5, a conduit 500 is depicted.

Conduit 500 extends to high altitudes. In an example embodiment, conduit 500 extends into the stratosphere (approximately 15km to 50 km above sea level). In other example embodiments conduit 500 may extend to other altitudes above or below the stratosphere. In example embodiments, high altitude conduit 100 may be coupled at its base end to the surface of the earth or other planet. The surface may include but is not limited to the ground, on the water, above the ground on a supporting structure, underground, underwater, and the like.

(0028] Referring now to FIG 2, a cross section of an example high altitude conduit 200 is depicted.high altitude conduit 200 includes a first outer material layer 210 and a second interior material layer 220. The two material layers form a space 230 or void between the two layers. In one example embodiment, space 230 may be filled with a gas that is lighter than the surrounding atmospheric air.

The gas may provide buoyancy to the conduit. The gas in space 230 may also be provided under pressure such that it helps to maintain the shape of conduit 200.

Gas in space 230 may be vented in a variety of manners including but not limited to through seams, vents, and holes, etc. The gas may be provided to conduit 200 by an introducer which may be in any of a variety of forms, including, but not limited to an exhaust outlet from a manufacturing facility or other industrial business, an outlet from a gas tank or other gas producing device, etc. In an example embodiment interior material layer 220 forms an elongated tube or cannula having an interior lumen 240. Interior lumen 240 may be used for a variety of purposes including but not limited to providing gasses and/or particulate to the atmosphere at a given altitude, providing an outlet for exhaust gasses at a given altitude. Thus, conduit 200 may be used as a high atmospheric chimney for

I

a manufacturing plant. Alternatively conduit 200 may be used to provide gasses and particulate into the atmosphere in an attempt to influence global warming or global cooling. It has been shown that certain gasses andlor particulate in the air may reflect incoming sunlight thereby reducing the amount of heat absorbed by the earth. Also, it has been shown that certain other gasses and/or particulate in the air may tend to trap heat close to the Earth's surface, thereby increasing the amount of heat absorbed by the Earth. By controlling the amount and type of gasses and/or particulate placed into the atmosphere, it may be possible to control to some extent the heating of the Earth. Delivery of such gasses and/or particulate may be provided by the use of high altitude conduit systems, such as are described here.

9] in accordance with other example embodiments, the gas used to support conduit 100 of FIG I may be any of a large variety of gasses including but not limited to hydrogen gas, helium gas, heated gas, exhaust gasses, etc. The introducer of the gas into the void for supporting conduit 100 may function to not only provide the gas but may also be used to pressurize the gas. Referring to FIG 2, in one example embodiment void 230 may be closed at the top of the conduit by a cap or sheet of material which substantially couples material layer 210 to material layer 220. In one example form, the cap or sheet of material may include one or more holes that act as vents for the void 230. It should however be noted that any of a large variety of methods and structures may be used to support conduit 100 and further that conduit 100 which is depicted in FIG 1 as a conduit may be representative of any of a variety of high altitude structures not limited to conduits.

0] Refemng now to FIG 3, a cross section of a conduit 300 is depicted.

Conduit 330 includes an outer material layer 310, and an inner material layer 320.

Inner material layer 320 forms an annular or other closed shape to form a lumen 330. in an example embodiment, a void 340 is defined by outer layer 310 and inner layer 320. In an example embodiment, because conduit 300 may be of a very elongated shape and may be formed from lightweight materials, a reinforcement or support structure may be needed to give conduit 300 at least one of shape and strength. In one example embodiment, the reinforcement structure may include supporting elements coupled to at least one of outer layer 310 or inner layer 320. For example, FIG 3 depicts example supporting structures 350 and 360. Supporting elements 350 may be cross braces formed of a lightweight material including but not limited to metals and metal alloys, composites, and plastics. In one example embodiment, the materials used for the supporting rib structures may be the same as those used for the conduit albeit in different shape and form. Structure 350 is depicted having cross braces 352 that extend between and are coupled to the inner and outer layers 310 and 320. In another example embodiment the support structure 360 may comprise radially extending braces 362. Further other supporting configurations may be used, such as but not limited to annular ring structures coupled to at least one of outer layer 310 and inner layer 320, lengthwise rib structures, helical rib structures, etc. Any of a variety of support structures may be used to help maintain a substantially upright orientation of structure 300 and further to support payloads which may be coupled thereto.

1]Conduit 100 and like conduits may be formed of any of a variety of relatively strong and lightweight materials, including but not limited to Mylar, ripstop nylon, Zylon, nanomaterials, latex, Chloroprene, plastic film, polyester fiber, etc. Other materials may similarly be used. Further materials may be combined in various combinations in order to achieve the performance characteristics required and desired. Conduit 100 may be formed of multiple layers of material and may include thermal insulation and the like.

2] Referring now to FIG 4, a high-altitude structure 400 is depicted. High altitude structure 400 includes but is not limited to any of a variety of materials which may be relatively lightweight, strong, and be capable of standing aloft in a variety of atmospheric, weather-related, and heating conditions. Further, structure 400 may be capable of being applied in a variety of environments and for a variety of applications including injecting or expelling certain materials into the atmosphere at various high altitudes for the purpose of affecting atmospheric change either locally or globally. Structure 400 may also and simultaneously be used in a variety of ways including as a supporting structure for equipment which may be attached to structure 400, as a vent for exhaust gases, or as a particulate or gas introducer, or the like. In the example embodiment depicted in FIG. 4, structure 400 has an approximately cylindrical shape forming an elongated cannula having an exterior wall 430 surrounding an interior wall 440. In a particular example embodiment a void 450 may be formed between exterior wall 430 and interior wall 440. The structure may be supported by introducing a gas into void 450 which may be lighter than the ambient air surrounding the structure.

Gas introduced into void 450 may come from any of a variety of sources. In the embodiment depicted, a conduit exit 410 is formed at the top of conduit 400.

Gasses or other materials including but not limited to solids, liquids, aerosols, mixtures, suspensions, and the like may be expelled from exit 410. Further, a conduit structure may have more than one exit at different altitudes, such as but not limited to exits such as exit 415 from which material may be expelled in a stream 425 as controlled by a valve 427. In a particular example embodiment, the material or alternatively the lighter than air gas in void 450 may come from a manufacturing facility 460 where gas may be manufactured for the purpose of supporting conduit 450 or the gas may be exhaust gasses from a manufacturing process at facility 460 such as but not limited to a fossil fuel burning process.

3] Referring now to FIG. 5, a high altitude conduit 500 is depicted. Conduit 500 is depicted as extending into the stratosphere. Typically, the tropopause which transitions the atmosphere to the stratosphere occurs at approximately 15 kilometers above sea level. The stratopause, which defines the upper boundary of the stratosphere occurs at approximately 50 kilometers above sea level. In accordance with an example embodiment, as shown conduit 500 extends into the stratosphere. Although facility may be provided by having conduit 500 extending into the stratosphere, other heights of conduit 500 may be useful as well. For example, it may be desirable to have a conduit extend at almost any height within the troposphere. It may also be useful to have conduits which extend beyond the stratosphere.

4] Referring now to FIG 6, a high altitude structure 600 is depicted. High altitude structure 600 is formed of a material 610 that extends in a substantially upward direction. An orbital anchor (satellite or other orbiting body) supports material 610 by a tether 630 coupled between material 610 and orbital anchor 620.

In an example embodiment, anchor 620 is, while anchored via tether 630 to material 610, in a geosynchronous orbit (powered or unpowered and controlled or uncontrolled) about the earth or other planetary body. The geosynchronous orbit would be outside of the majority of earth's atmosphere represented by line 650. Tn an example embodiment, a material 640 may be expelled from the conduit. High altitude structure 600 has essentially the same function as that discussed with reference to FIG 4 in that it may be used to affect climate change and/or atmospheric changes either locally or globally. Tether 630 may be formed of any of a variety of matenals having a high strength to weight ratio including but not limited to carbon nanotube fibers. A base 660 of structure 600 may be supported on the ground, underground, underwater, in the air or, as depicted floating on a body of water 670. Allowing the base 660 to move may make it easier to control the top of the structure 600 as variance of tension of the tether 630 may occur.

Also having the ability to have the base movable may be advantageous in allowing less stress on the structure itself. One advantage of having base 660 being on the water may be that ocean water may be used in creating the material to be expelled. For example, it may be desirable to use ocean water to create halide mists that may be carried up the conduit structure and expelled into the atmosphere. The introduction of halide mists into the atmosphere may aid in creating an albedo effect in which some solar energy impinging on the Earth's atmosphere is reflected. This albedo effect may aid in reducing the effect of global warming.

5] Referring now to FIG. 7, another example embodiment of a conduit 700 is depicted. Conduit 700 may comprise an outer wall layer 710 which defmes an elongated lumen 720. Conduit 700 may be held aloft by one or more balloons 730 or other devices used to maintain conduit 700 in an upright position. Other such devices may include but are not limited to airfoils, parafoils, and kites or other aerodynamic lifting surfaces; propellers, rockets, and jets or other thrust providing devices. Yet other structures for keeping conduit 700 aloft include momentum coupling to a vertically moving mass stream, such as but not limited to electric or magnetic coupling to moving projectiles or drag or thrust coupling to gas or liquid flows. Further, conduit 700 may be a double walled conduit as discussed earlier which provides additional buoyancy in combination with balloons or other lifting devices.

6] In an example embodiment the carrier such as balloons 730 contain Hydrogen gas, Helium gas, heated gas, an exhaust gas, or other lighter than atmospheric air gas. In an example embodiment an introducer pressurizes the gas into a space in the one or more carrier. This pressurized gas may be carried from ground level through a tube or the like. Conduit 700 may be used in the same maimer as the conduits described above to expel material into the atmosphere at high altitudes to affect local or global atmospheric change. Such atmospheric change may also include the process of inducing precipitation by cloud seeding.

7] In another example embodiment conduit 700 may be a hose or a series of hose segments which are coupled to the carrier on one end and coupled to a pump at or near the Earth's surface. In one embodiment, multiple pumps may be used along the length of conduit 700. Also, in another embodiment, conduit 700 may include support cabling or tether cabling, the support or tether cabling may also double as power delivery cabling to one or more devices along the length of conduit 700.

8] Referring now to FIG 8, a process 800 of affecting atmospheric change is depicted. Process 800 includes providing a high altitude conduit extending upward into high altitudes (process 810). The process also includes providing a first material through the conduit (process 820). The material will include at least in part, the substances which are effective in creating the atmospheric change desired. Process 800 further includes expelling the first material through at least one conduit opening into the atmosphere at high altitude (process 830). Once expelled into the atmosphere, the materials will be carried and distributed by high altitude winds.

9] Referring now to FIG. 9, a process 900 of affecting terrestrial temperature change is depicted. Process 900 includes providing at least one high altitude conduit (process 910). In addition to the single conduit many conduits may be provided. These may be distributed in a small area, a region, within a country, within a group of countries, or worldwide, depending on the desired results and the application. Process 900 also includes providing a first material through the conduit (process 920). The material will include at least in part, the substances which are effectivein creating the terrestrial temperature change desired. Process 900 further includes expelling the first material through at least one conduit opening into the atmosphere at high altitude to cause at least one of greater reflectivity of solar energy impinging on the earth or changing the amount of pollutants andlor carbon dioxide in the atmosphere to reduce global warming affects (process 930).

0] Referring now to FIG. 10, a process 1000 of determining the distribution of an aerosol in the atmosphere is depicted. The process includes providing a conduit supported by lifting forces (process 1010). The lifting forces may come from at least one of buoyancy effects of the high altitude conduit itself, aerodynamic lifting surfaces, propulsive devices, or at least one carrier. Process 1000 also includes providing a first material through the conduit (process 1020) and expelling the first material through at least one conduit opening into the atmosphere (process 1030). Once the material has been aerosolized and expelled into the atmosphere process 1000 includes tracking the distribution of the first material in the atmosphere over time (process 1040). This tracking of the aerosol may enable researchers or demonstrators of the technology to approximate or predict the distribution of aerosol when the conduit and related expelled materials are put into practice at the same or possibly higher altitudes. Tracking may be accomplished by any of a variety of ways, including but not limited to putting dyes (e.g. fluorescing dyes) into the expelled material. With dyes in the expelled material, imaging equipment either airborne, earthbound, or spaceborne may be used to track the dispersal and/or distribution of the expelled material. In accordance with example embodiments, the tracking techniques may be applied to control of a high altitude system as well as for use in demonstration and testing at lower altitudes.

[00411 In accordance with one example embodiment, the desired effect may be to scatter light by injecting particles into the atmosphere effectively increasing the Earth's albedo. In another example embodiment, it may be desirable to use anthropogenic aerosols to cause reflectivity changes. This indirect effect is known as the Twomey effect. Aerosols may act as cloud condensation nuclei and thereby leading to greater numbers of smaller droplets of water. Large numbers of smaller droplets of water or other substances can diffuse light more efficiently than just a few larger droplets.

2] Particulate injection into the atmosphere may also result in changes in the particle size distribution in the atmosphere, which can affect atmospheric reflectivity properties. Anthropogenic particulates are therefore one candidate to affect global dimming, which may act to offset some of the effects of global warming. Examples of anthropogenic particulate includes but is not limited to metals, dielectrics, and combinations of these. Examples of metals include but are not limited to aluminum, gold, and titanium. Examples of dielectrics include but are not limited to sulfates, halides, and carbon compounds.

3] Conventionally, it is believed that the effect of global dimming is probably due to the presence of aerosol particles or particulates in the atmosphere.

Aerosol particles and particulates scatter incident solar energy and reflect sunlight back into space. Particulates can also become nuclei for cloud droplets. It is thought that the water droplets in clouds coalesce around the particulates.

Increased particulates, creates clouds consisting of a greater number of smaller droplets, which in turn makes them more reflective, thereby reflecting sunlight back into space.

4] Clouds intercept both heat from the sun and heat radiated from the Earth.

Their effects vary in time, location and altitude. Usually during the daytime the interception of sunlight predominates, giving a cooling effect; however, at night the re-radiation of heat to the Earth slows the Earth's heat loss. Usually for high altitude clouds, the re-radiation of heat from the Earth predominates, leading to increased warming. Usually for low altitude clouds, the reflection of sunlight predominates leading to increased cooling. In one example embodiment therefore, it may be beneficial to nucleate high altitude clouds to reduce the amount of heat re-radiation. In other example embodiments it may be beneficial to nucleate low altitude clouds to increase reflection of sunlight. In other example embodiments, it may be desirable to inject into the atmosphere either materials that absorb energy from the sun or materials that scatter, absorb, or reflect thermal radiation. In one example embodiment it may be desirable to increase the absorption of solar radiation by the Earth's atmosphere in order to increase or upwardly influence terrestrial temperatures. Such absorption may be accomplished by the addition of water droplets in the air that may contain impurities such as soot or other materials. Also, carbonaceous materials may also be advantageous. Further, materials containing one or more optical absorbers such as dyes, direct band-gap semiconductors, or metal oxides may also be advantageous. Further still,, particles may be designed having various colors, optical cross sections, sizes and/or geometries in order to accomplish given performance objectives.

5] Some climate scientists have theorized that aircraft contrails (also called vapor trails) are implicated in global dimming, but the constant flow of air traffic previously meant that this could not be tested. The near-total shutdown of civil air traffic during the three days following the September 11, 2001 attacks afforded a rare opportunity in which to observe the climate of the USA absent from the effect of contrails. During this period, an increase in diurnal temperature variation of over I C was observed in some parts of the US, i.e. aircraft contrails may have been raising nighttime temperatures and/or lowering daytime temperatures by much more than previously thought. Therefore, in one example embodiment the process of creating atmospheric change may be characterized as changing the opacity of the atmosphere.

6] In yet another example embodiment, halides may be used to affect global dimming. A halide is a binary compound, of which one part is a halogen atom and the other part is an element or radical that is less electronegative than the halogen, to make a fluoride, chloride, bromide, iodide, or astatide compound. Many salts are halides. All Group 1 metals form halides with the halogens and they are white solids. As stated earlier, it may be possible to harvest halides from the ocean to be expelled through a high altitude conduit as a mist. This injection may be done using dry halides or wet halides, e.g. sea water droplets or mist. Alternatively pseudohalides may also be used to affect global dimming. Pseudohalides resemble halides in their charge and reactivity. For example azides NNN-, isocyanate -NCO, Isocyanide, CN-, are examples of pseudohalides. This process of global dimming utilizes one or more of the aforementioned materials or other materials to scatter or reflect solar radiation impinging on the Earth's atmosphere.

In other example embodiments it may be desirable to use similar materials andlor techniques to reflect, scatter, or absorb reradiated thermal energy from the Earth's surface.

7] In accordance with another example embodiment, the reflection or scattering of thermal radiation by the Earth's atmosphere may be accomplished by using natural or engineered particles that are expelled at high altitude including micro-wire structures or micro-crystalline structures that have mesh andlor lattices that have lattice sizes that are matched to the infrared wavelength range so that some of the infrared radiation is reflected by the Earth's atmosphere containing these particles. Many other geometries, sizes, materials, and shapes may similarly be used.

8] In accordance with yet another example embodiment, the absorption of thermal radiation by the Earth's atmosphere may be accomplished by using natural or engineered particles that are expelled at high altitude. Such particles may contain materials with high absorptivity for thermal radiation wavelengths, such as carbonaceous materials, or narrow band-gap semiconductors, such as indium antimony (InSb), Indium Arsenic (InAs), lead telluride (PbTe), or similar materials.

9] In yet still another example embodiment it may be desirable to scavenge carbon dioxide from the atmosphere by expelling carbonate aerosols into the atmosphere. The carbonate aerosols may combine to form carbonic acid droplets in the atmosphere. The carbonic acid undergoes disassociation to bicarbonate and carbonate ions before precipitating to the ground. This scavenging process is not limited to the chemicals disclosed, but other chemicals having similar properties may also be applied.

0] In yet a further example embodiment, cloud seeding, which is a form of weather or atmospheric modification, is an attempt to change the amount or type of precipitation that falls from clouds, by dispersing substances into the air that serve as cloud condensation or ice nuclei. The conventional intent is to increase precipitation, but hail suppression may also be accomplished. The most common chemicals used for cloud seeding include but are not limited to silver iodide and dry ice (frozen carbon dioxide). The expansion of liquid propane into a gas, causing liquid water to freeze into ice crystals that may fall out as snow, is being used on a smaller scale. Hygroscopic materials, such as salt, may also be used.

1] In mid-latitude clouds, the usual seeding strategy has been predicated upon the fact that vapor pressure is lower over water than over ice. When ice particles form in supercooled clouds, the ice particles are allowed to grow at the expense of liquid droplets. If there is sufficient growth, the particles become heavy enough to fall as snow (or, if melting occurs, rain) from clouds that otherwise would produce no precipitation. This process is known as "static" seeding.

2] Seeding of warm-season or tropical cumuliform (convective) clouds seeks to exploit the latent heat released by freezing. This strategy of "dynamic" seeding assumes that the additional latent heat adds buoyancy, strengthens updrafts, ensures more low-level convergence, and ultimately causes rapid growth of properly selected clouds.

3] In another example embodiment, cloud seeding may be used to reduce precipitation. This may be accomplished by the creation of downdrafts in cumulonimbus clouds leading to the dynamic destruction of the cumulonimbi. In an example embodiment the tops of the clouds may be seeded with a powdery material which causes downdrafts within the clouds. Also, other substances may be used including but not limited to water which is dispersed into the tops of the cumulonimbi.

4] Conventionally cloud seeding chemicals may be dispersed by aircraft or by dispersion devices located on the ground (generators). in the example embodiments described, the chemicals may be transported and expelled at high altitudes through the high altitude conduit structures described above.
