BACKGROUND
Ice construction vehicles of which the inventor is aware typically include a vehicle spreading water obtained from a truck or a stationary or semi-mobile pump combined with specialized nozzle setups for spraying water. Such systems are manned or require significant man-hour maintenance and support for setup and operation. The diffusion of water to form ice in below freezing temperatures is used for making snow, ice platforms, formations and massifs, roads and airstrips, as well as, off-shore industrial uses.
There are several ice-related problems including flooding during spring break-up of ice, loss of animal habitat as a result of ice free polar seas and loss of ice at the poles and its impact on the climate future. At latitudes having extended seasonal freezing, marine environments in response to rising spring temperatures cause billions of dollars in property damage as a result of spring thaw.
Sea ice increases the health and area range of wildlife. For example, seals raise, rest, and protect young on free flowing ice during the Arctic summer season. Polar bears also utilize sea ice to rest on while hunting.
Polar regions act as a heat sink or counter-weight to the heat regions of the globe, such as the tropics. Planetary differences in energy are a major influence driving atmospheric wind and ocean currents.

For example, during a drilling operation a rotational forces applied to the drill pipe while allowing a particular amount of vertical slippage of the drill pipe during rotation. As such, the applied rotational force varies the physical contact between the drill pipe and drive system 408 in order to allow for vertical slippage downward during drilling.
In at least some embodiments, one or more vertically oriented drive wheels may be used to lower or raise drill pipe 404 to a desired depth or to align with one or more locking pins 410.

In accordance with the particular scenario, drilling system 116 extends through ice 102 into water 104.
IBM 700 additionally comprises a locomotion device 702 to move the machine from location to location or along a predetermined path. In at least some embodiments, locomotion device 702 is a set of wheels in combination with an engine, e.g., wind-powered, pneumatic-powered, combustion powered, etc. In at least some embodiments, IBM 700 comprises a set of 3, 4, or more wheels. In at least some embodiments, all wheels are driven by the engine thereby providing all wheel drive to IBM 700.
In at least some embodiments, all wheels of locomotion device 702 are 360° directionally steerable. In at least some embodiments, wheels having the ability to steer and drive IBM 700, while on station and building ice structures, is helpful to keep turbines directed into a wind flow in order to free drill pipe 404 by the use of rotational force of IBM 700, in particular chassis 114.
In at least some embodiments, an operator creates a desired path for IBM 700 with respect to a location for a particular ice structure positioned on a map using a computer system. The desired or predetermined path is then transferred to IBM 700 and stored in control module 110 to determine commands provided to locomotion device 702 as the machine operates.
In at least some embodiments, the predetermined path is specified through the use of machine recognizable survey stakes which are placed along the path in a work area. In at least some embodiments the machine recognizable survey stakes are used to specify areas or features to be avoided or where additional spray time is needed and/or where different spray parameters may be used.
In at least some embodiments, the machine recognizable survey stakes comprise radio frequency identifiers embedded within the states which are readable by and/or responsive to a signal from IBM 700 to transmit information to the machine. For example, the information may identify spray/don't spray areas, areas in which operator assistance may be needed, nesting areas to be avoided, new structures not included on a map, or hazards such as overhead cables or underwater pipelines.
Operational Description
In at least some embodiments, IBM 100 is outfitted and sized according to the type of work and conditions expected. For example, a machine 100 working on sea ice obtains power from the wind and carries a longer drill pipe and ice screws. For local work, replacing or aiding the wind turbine, an additional internal combustion engine (ICE) is added to provide power for machine 100 to work.
Nozzles types and sizes also vary, depending on the work and weather conditions expected. in some embodiments, nozzles comprise variable direction of spray (up, down and sideways) and various types of nozzles are fitted for expected flow rates and sizing of particles dispersed. More sophisticated nozzles are useable which have machine controlled adjustments for flow rate, particle dispersion size, direction of spray, etc.
Similarly, if the remote area of operation is found to have steady and constant wind events with little wind speed variation (undesirable gusting), then a purely wind powered machine uses hydraulics as the primary working fluid with electricity generation being a secondary form of energy for powering the machine's electric devices. In at least some embodiments, machine 100 uses electric and hydraulic force in operation. Because of cost, reliability, packaging and other considerations, using hydraulics for mobility, drilling and pumping/spraying (the biggest energy uses) increases overall efficiency.
Upon receiving instructions (software instructions) at the machine location or from a remote operator, machine 100 fully charges an on-board battery and accumulates working fluid in, e.g., an accumulator derived from the drill pipe or an alternate water intake.
Typically, as the seasonal temperature averages move below freezing, machine 100 accumulates energy for work, to first move to a given location on or near the frozen surface of a marine body. As machine 100 travels to predetermined GPS coordinates, on board sensors, e.g., navigation devices, aid in navigation. In at least some embodiments, additional sensors detect anomalies in the ice and atmosphere. Anomalies are those environmental features not normally present in a predetermined static environment. Translated into digital code from energy transmission and detection equipment, recording “hits”, anomalies include mammals, machines, open water, thin ice, pressure ridges, biomass, geologic shapes, etc.
As programmed, machine 100 responds to anomalies in a predetermined manner and reports higher status anomalies wirelessly to other machines and/or to a remote human controller via a wireless network connection. Example anomalies include open water at sea, called, “leads”. When a lead is detected by a traveling IBM 100, the machine stops and reports the condition.
Without human intervention, machine 100 determines if the lead is “bridgeable”, i.e., where the machine builds an ice bridge for crossing the lead, or if it is better to go around the area of open water by straying off of a direct path to the predetermined coordinates. By networking, machine 100 is able to determine the movement of ice in relation to a given location. By “knowing” the predicted winds, wind speeds and ice sheet drift, etc., at the actual location of other machines 100, a given machine is able to avoid ‘anomalies’ and/or cross over and/or avoid objects in order to travel in an efficient manner.
When not able to travel over an obstacle, such as moving edges of a lead or a lead which is too wide, or when pressure ridges are too tall or growing, machine 100 moves parallel to the anomaly until a crossing is found. After altering a planned course, machine 100 self corrects to the predetermined destination or receives alternate instructions from remote command.
Basic command instructions include stopping diffusion and transit operations within a given distance of mammals, recognizable markers, and other machines 100. Avoidance maneuvering around anomalies and reporting for human intervention when and before machines or objects become endangered.
With downward looking radar or other detection equipment, machine 100 determines if a particular path of travel upon the ice is of a density and thickness sufficient to support travel of the machine. In the presence of deep snow (of a predetermined density and depth) and with access to water, machine builds an ice surface ahead of its direction of travel by icing or hardening a proposed travel surface. Machine 100 determines when to autonomously access and diffuse water upon a surface to aid in traveling over deep snow, leads or pressure ridges, etc. Machine 100 makes use of ice structures built for transportation by other machines.
On station, machine 100 drills a hole in the ice by rotating the drill tower with a drill or coring bit to be able to drill through an ice sheet to obtain water. Having made a whole at the desired location, machine ejects ice core with pneumatic force supplied by pneumatic pump, then pumps and sprays water upon or near body of water in a manner desired and within weather conditional parameters.
If a wall of ice is desired, machine 100 travels along predetermined frozen marine shores and waterways, which have hanging nearby material (likely fabric) supported by one or more masts along the desired path of the wall. Hanging material is to arrest and guide the sprayed water, thereby forming a vertical accumulation of ice. Repeated spraying during sub freezing temperatures results in a wall of ice, in a location desired and, if sized appropriately, able to withstand spring flooding.
Where a lake or the sea surface freezes, machine 100 drills a hole to pump water, for making artificial ice bergs or ice structures such as roads, air strips, industrial platforms and massifs grounded near shore on an open polar sea.
Instead of a precise location of sprayed water forming an ice wall, machine 100 pumps as much water onto the surface as possible to build less precisely laid structures. Low temperature and high wind allow a more solid stream of water to be pumped in a flood freeze manner—versus a finer spray needed with higher freezing temperatures and no wind—in order to have similar freeze rates of accumulating water/ice.
In making ice patties, e.g., regions of a surface such as land, water, or other existing snow/ice, machine 100 diffuses spray with the aid of the wind only far enough from the machine to keep the machine from freezing in place from accretion and or runoff. Water may also be sprayed in such a manner as to form frozen shapes upon the ice.
FIG. 27 is a high-level functional block diagram of a flow chart of an operational process flow 2700 of operation of IBM 700 according to an embodiment. The process flow begins at startup functionality 2702 wherein control module 110 begins execution of a set of instructions stored in memory, e.g., a computer-readable medium. In at least some embodiments, the set of instructions is received via a wired and/or wireless connection to a remote or separate computer system and stored in memory. In at least some embodiments, control module 110 also receives a predetermined path along which the machine 700 is to follow and spray water at locations to build ice structures. In at least some embodiments, the predetermined path comprises a single location whereas in other embodiments, the predetermined path comprises multiple locations, dwell times, spray parameters, and other parameters. In at least some embodiments, some of the other parameters include a minimum temperature at which to begin spraying, a minimum time period or a limited time range during which to spray, a set of parameters related to obstacles to be avoided, etc. Depending on time/day considerations and/or environmental factors, e.g., whether the temperature is sufficient to build ice structures, the process flow proceeds to either functionality 2704 or move functionality 2706.
If the weather is not acceptable, i.e., below a predetermined threshold value for ice building, and machine 700 does not have sufficient stored energy to move to a first spraying location, the process flow proceeds to functionality 2704 and the machine proceeds to acquire sufficient energy to move to the first spraying location. In at least some embodiments, machine 700 comprises another energy source such as a combustion or other energy source which can provide energy for moving the machine and the flow proceeds to functionality 2706 without acquiring energy in functionality 2704. After acquiring sufficient energy, the process flow proceeds to return to startup functionality 2702 and then to move functionality 2706.
During execution of movement functionality 2706, machine 700 responsive to inputs comprising at least navigation information from navigation device 308 (FIG. 3) moves along the predetermined path to a first spraying location. In at least some embodiments, machine 700 is a buoy and need not have or execute move functionality 2706.
If during execution of move functionality 2706, machine 2700 detects an obstacle, e.g., an animal, a lead, etc., the machine performs an avoidance maneuver 2708. For example, machine 700 may detour around or proceed to build an ice bridge across an obstacle.
In at least some embodiments, machine 700 stops along predetermined path if needed to acquire additional energy.
After arriving at the first spraying location, the process flow proceeds to perform ice building functionality 2710. During execution of functionality 2710, machine 700 uses drilling system 116 (FIG. 1) to access water below the surface and spraying system 120 in combination with pumping system 118 to pump and spray accessed water toward a desired surface. In at least some embodiments, machine 700 uses an alternate water intake to access water without requiring drilling.
Execution of access water functionality 2712 causes machine 700 to operate drilling system 116 to drill with drill pipe 404 through an ice sheet 102 to access water. After accessing water or drilling to a predetermined depth, the process flow proceeds to spray functionality 2714.
Execution of spray functionality 2714 causes machine 700 to operate pumping system 118 to pump accessed water to spraying system 120 and to operate the spraying system to spray the water toward the predetermined surface.
During execution of ice building functionality 2710, e.g., concurrent with, intermittently during, or prior to or after completion of functionality 2712 and 2714, machine 700 (in at least some embodiments) executes acquire energy functionality 2716 similar to functionality 2704.
After completion of ice building functionality 2710 at the first spraying location, if additional spraying locations have been specified the flow proceeds to move functionality 2706 to move to the next spraying location.

FIGS. 17A and 17B are cutaway views of a marine waterway at sequential time periods. The passage of time between T1 (FIG. 17A) and T2 (FIG. 17B) represents the buildup of ice over time. IBM 1700 is a fuel powered vehicle and a second IBM 1702 is powered by the wind. IBM 1700 is building a protective ice wall while IBM 1702 is impounding highland water and or building ice on a surface for erosion protection. Each of machines 1700, 1702 work autonomously when weather permits.
FIG. 18 is a view of an example of a shape used on a polar sea in accordance with at least some embodiments. IBM 800 would be used to make semicircle ice walls open toward the prevailing winds in order to facilitate the accumulation of surface blown snow within said circular wall of ice. This arrangement efficiently makes an accumulated ice (and drifted snow) formation which is able to sustain its mass longer into the warm season. FIG. 18 depicts a pair of baffles 1800 positioned within a semicircle to disturb wind, thereby causing accumulation of wind blown material. Shapes are built in lines North and South so as to give a timed release of structures as ice melts in the warm season. Structures are sized to provide animals habitat and seeding for earlier season freeze up. In at least some embodiments, greater or fewer number of baffles 1800 are used.
FIG. 19 is a top view of an example of highland impounding using more than one IBM 800. Several IBMs 800 working along a marine body, such as a river, to impound water in the form of ice, snow or water and (in at least some embodiments) using sediment or other insulation. In at least some embodiments, upstream impounding for water resource management and the reservation of fresh water runoff is performed using one or more IBMs 800.
FIG. 20 is a top view of an example of creating ice roads and/or landing strips, especially those on or near a marine body. In at least some embodiments, such built ice structures have an earlier open and later closure to the useful operating season when those structures are built and maintained by described autonomous IBM 800.
FIG. 21 is a top view of another example embodiment of desired ice construction using several IBMs 2100 (similar to IBM 800). of the depicted arrangement comprises a kind of spray ice and flood freeze platform designed for use by the oil industry and, in at least some embodiments, the creation of a mass of ice large enough to protect coastal communities affected by erosion.
Using less independent ice building machines (for example, wired (or tethered) or wirelessly connected IBMs 2100), large masses are built using a central power and water barge 2102 or similar platform/mother ship, to supply ice building machines by way of a tether for the supply of power and water to the IBMs. The barge 2102 supplies energy for mobility and spray heads and material to be diffused (for example, desalinated water) from a central location.
FIGS. 22A and 22B are side views of IBMs 2100 at sequential time periods. The passage of time between T1 (FIG. 22A) and T2 (FIG. 22B) represents the buildup of ice over time. IBMs 2100 are connected to a central barge 2200 anchored/secured in place, multiple machines connected by tether, build ice around a central location. Ice formed according to this scenario is limited in size by the duration of the sub-freezing season and the size and number of machines deployed independently or on a tether.
Wind and/or fuel powered IBMs 800 are programmable to build a single large mass of ice in one location. The mass extends to the bottom of a marine body as ice is accumulated upon the surface. The mass is held in place by central barge 2200 anchors, pilings 1600 (FIG. 16) and/or cables secured to the marine floor.
A reel supplying water and power (via tether) connects to barge 2200 at the point of deploying an ice builder 800, 2100 and a second supply reel (tether) connected with the ice builder 800, 2100. The use of two reels to supply each mobile sprayer 800, 2100 allows for greater range and other benefits.
At the center of the ice mass are platforms for supplying fresh water and electricity to tethered ice builders 2100 and fuel and services to untethered ice builders 800. Platforms also serve as a foundation for industry standard oil and gas operations.
Ice builders 800 work in a circle around the central supply/drill location, to build a massive column with a thickness impervious to the movement of ice sheets and tall enough to be anchored to the bottom of a marine body. Sized large enough to withstand the warm season, such ice structures are rebuilt during subfreezing temperatures.
FIG. 23 is a side view of an ice structure constructed in a location where the sea floor is at or near the water/ice surface, e.g., in sand bars and other formations. Marked by buoy 2300 and using a similar anchorage mechanism as for massif formation. The built ice structure is grounded upon the sea floor, is made to stay in place, as primarily an animal habitat, with sizing to withstand the polar summer, wind and water currents etc., until rebuilding each winter as illustrated and described above.
Buoy-Related Embodiment
FIG. 24 is a side sectional view of an anchored IBM 2400 (similar to IBM 800 of FIG. 8) depicted according to an embodiment. The anchored IBM 2400 is positioned anchored within at least a portion of an ice sheet. In at least some embodiments, IBM 2400 floats in a body of water.
Buoy IBM 2400 comprises a buoyant body 2402 having a concave central portion about which ice 2401 may form in addition to ice sheet 102. Buoy IBM 2400 also comprises a mast 2404 connected to an upper end of body 2402 for supporting the wind turbine 804, spray nozzles 816, a navigation light or marker 2406, and an antenna 2408. Navigation light/marker 2406 is used to communicate with a remote computer system and/or other machines 100, 700 and/or to provide an indication of the location of buoy IBM 2400.
Mast 2404 is hollow and comprises a conduit 2410 axially and vertically extending through the mast. Conduit 2410 extends vertically through body 2402 and below the water line and ice 102 into the water 104. A lower end of conduit 2410 is open as a water intake 2412 in order to supply water via a pump to spray nozzles 816. Water intake 2412 is surrounded by a filtering screen to preclude the entry of non-liquid material into conduit 2410 and avoid clogging of spray nozzles 816. A main portion of buoy IBM 2400 comprises a fuel storage area 2416 for storing fuel for an engine 2418. Engine 2418 is positioned in a lower portion of buoy IBM 2400 and operates to generate electricity for powering elements of buoy IBM 2400. Buoy IBM 2400 also comprises a pump 2420 for transporting fluid taken in by water intake 2412 to spray nozzles 816. Also included in buoy IBM 2400 to ensure upright orientation of the machine is ballast 2422.
In at least some embodiments, the anchored IBM 2400 is deployed at the beginning of a polar cold season. In at least some embodiments, the IBM 2400 includes a fuel, such as propane, along with an engine for generating power to operate the IBM by burning the fuel to generate electricity. The engine is used in the absence of or presence of a minimal amount of wind and during a time period when exterior temperatures are low enough to cause freezing. The engine is operated to generate power and/or wind-based power generation is used to spray fluid onto a surface surrounding the anchored IBM 2400. The sprayed fluid, as a result of the temperature and spray parameters, freezes onto the surface and a buildup of the frozen spray forms an ice structure surrounding the IBM 2400.
In at least some embodiments, IBM 2400 differs from IBM 800 in that the body shape of the buoy-style IBM is arranged to withstand the impact of ice flows and to be conducive to the buildup of an ice structure surrounding the buoy-style IBM. In at least some other embodiments, IBM 2400 lacks a locomotion device for propelling or moving the machine. In at least some embodiments, IBM 2400 lacks a drilling system 116 as part of fluid spray system 112. In at least some embodiments, due to the lack of the power drain related to locomotion of the machine, more power is used with respect to pumping and spraying of ice.
In at least some embodiments, buoy-style IBM 2400 is not anchored to a particular location and instead drifts freely in a body of water. In at least some embodiments, buoy-style IBM 2400 drifts floating in mapped ocean and/or sea currents. Such drifting buoy IBMs 2400 in operation perform the same ice building of structures as described above and, in at least some embodiments, build floating ice islands surrounding the IBM. In at least some embodiments, the creation of such ice islands provides sanctuary and/or habitat for wildlife such as polar bears and seals. Further, due to the networked communication and reporting of IBM 2400, such ice islands pose less of a hazard to navigating vessels than natural ice bergs.
FIG. 25 is a side view depicting ice buildup at a predetermined distance from the anchored IBM 2400 of FIG. 24.
FIG. 26 is a top view of the anchored IBM 2400 of FIG. 24 with a built up ice structure comprising an outer ring of ice.
Materials And Designs
Not shown are pumps, plumbing, motors, connectors, valves, generators, switches, etc. Prior art and industry standard practices are well understood regarding hydraulic, pneumatic, electric and digital device descriptions and operations expected. Design must be efficient especially when powered by the wind and all designs must be able to withstand the extreme cold.
Converted rotational energy for work can be fluid, electric, and or direct mechanical linkage, dependent on cost and performance desired. Likewise, materials to make machine can be durable or disposable. Likely, a lower cost machine might use wood and plastic, in place of aluminum where cost is an issue.
All machines use heat tape or similar heating device, especially when operating in variable winds, placed to unfreeze/unstick moving parts, to keep components from freezing and to clear ice accumulated on the machine.
Similar to Unmanned Arial Vehicles, UAVs, an Unmanned Surface Vehicle of the type described above, in some embodiments, builds protective ice walls, artificial ice bergs and seeds the polar oceans for earlier freeze-up in addition to building conventional ice structures and snow formations. The above-described USV travels upon the ice, drills through the surface and pumps water or sprays water to a given location. A more general description is a self guided mobile machine which travels to a location, accesses a fluid and sprays, pumps or diffuses said fluid or another fluid (tether and tank fed) to a desired location. In another embodiment, the ice building machine is not mobile and is instead fixed in a single location.
PROTECTIVE ICE WALL—EXAMPLE #1
Along and upon a frozen river surface, an ice building machine according to an embodiment builds protective ice walls, dividing areas of potential spring flooding and property of value. With a local fuel source, machine size, numbers deployed and atmospheric conditions are the limits determining the size of the protective/flood wall. FIGS. 17A and 17B are side views depicting a first embodiment, i.e., an engine powered remote robotic ice builder (RERIB) corresponding to an embodiment of IBM 100 building a protective ice wall and a second embodiment, i.e., a wind powered RERIB (similar to IBM 100), building erosion protection ice.
Related and alternate uses of the ice building machine include coastal protection, water/ice impounding, sculptor quality ice, off season electric generation, or use as a local water pump for fire, flood, utility purposes.
ARTIFICIAL ICE BERGS—EXAMPLE #2
Working remotely upon a frozen polar sea, an ice building machine according to at least some embodiments, uses wind instead of a local fuel to power similar operations as described above with respect to example #1. Instead of a local ice wall, the ice building machine makes artificial ice bergs. Ice building machines according to such an embodiment are wide ranging and self-navigating, and able to make large ice masses which give habitat to wild life and which last through out a warm season of a particular polar region. Ice remaining in the fall aids the sea in earlier freeze-up.
In the spring, ice building machines park on land and provide local power from onboard mills or migrate closer to the respective pole, on permanent ice, awaiting fall freeze-up.
GEO-ENGINEERING—EXAMPLE #3
The major oil companies have a pattern of being the assignee to invention designs of various ice islands/drilling platforms which are impervious to moving ice sheets. These are shallow, i.e., less than approximately 100 feet in depth, water, massive ice structures described variously in class 405/217 and other classes/subclasses. Ice building machines according to at least some embodiments build ice islands at lower cost. With slight variation of design, e.g., including the use of tethered machines and multiple independent machines, an ice island grounded on the sea floor is possible.
Likewise on a larger scale, the desire is to bypass the insulating effect of surface ice sheets by exposing seawater to the colder ‘topside’ atmosphere, on the surface. Heat trapped in the ocean is then released into space via the cold polar night. A multitude of ice building machines according to at least some embodiments are able to achieve this effect over a wider area.
Australia needs the ocean currents, winds and or climate at the southern pole to change in order to impact the long existing drought in the region. Slowing down the rate of climate change is of growing interest internationally.
It will be readily seen by one of ordinary skill in the art that the disclosed embodiments fulfill one or more of the advantages set forth above. After reading the foregoing specification, one of ordinary skill will be able to affect various changes, substitutions of equivalents and various other embodiments as broadly disclosed herein. It is therefore intended that the protection granted hereon be limited only by the definition contained in the appended claims and equivalents thereof.
