1. In a water environment in conjunction with one or more types of oil, wherein at least part of the oil is mixed with water to form an emulsion, a method of in-situ burning comprising: placing a fire-resistant sorbent material in contact with the oil or emulsion;allowing the oil to wick into the so
1. In a water environment in conjunction with one or more types of oil, wherein at least part of the oil is mixed with water to form an emulsion, a method of in-situ burning comprising: placing a fire-resistant sorbent material in contact with the oil or emulsion;allowing the oil to wick into the sorbent material and demulsifying the emulsion by the sorbent material to separate the oil from the water;burning the oil using the sorbent material as a wick, wherein the sorbent material is not burnable and is not burned during the burning of the oil; andactively aerating the sorbent material with pressurized fluid to facilitate burning of the oil. 2. The method of claim 1, wherein the oil is floating on top of the water, and wherein the allowing step separates the oil from the water. 3. The method of claim 1, wherein the aerating includes: providing at least one pipe, the at least one pipe including a vented segment having a plurality of vents therein;disposing each vented segment in a batt of the sorbent material; andallowing air to travel through the at least one pipe and exit the vents thereby aerating the batt to increase burning efficiency. 4. The method of claim 3, wherein the burning draws the air into the at least one pipe. 5. The method of claim 3, wherein the aerating includes pumping air into the at least one pipe. 6. The method of claim 3, further comprising forcing a fire-suppression material through the at least one pipe and into the batt via the vents to extinguish the burning. 7. The method of claim 1, wherein the placing step includes positioning at least part of the sorbent material above, and at least part of the sorbent material in contact with, the oil on the surface of the water or the oil/water emulsion. 8. In a water environment in conjunction with one or more types of oil, wherein the oil is floating on a surface of the water, a method of in-situ burning comprising: placing a fire-resistant sorbent material in contact with the oil;allowing the oil to wick into the sorbent material; andburning the oil using the sorbent material as a wick, wherein the sorbent material is not burnable and is not burned during the burning of the oil, and wherein the placing step includes positioning at least part of the sorbent material above, and at least part of the sorbent material in contact with, the oil on the surface of the water, and wherein the oil is a layer floating on the surface of the water, and the placing step includes submerging a part of the sorbent material to a depth comparable to a thickness of the oil layer. 9. The method of claim 1, wherein the sorbent material is not consumed during the burning, and wherein the oil wicks into the sorbent material by at least one of absorption or adsorption. 10. In a water environment in conjunction with one or more types of oil, wherein at least part of the oil is mixed with water to form an emulsion, a method of in-situ burning comprising: placing a fire-resistant sorbent material in contact with the oil or emulsion;allowing the oil to wick into the sorbent material and demulsifying the emulsion by the sorbent material to separate the oil from the water; andburning the oil using the sorbent material as a wick, wherein the sorbent material is not burnable and is not burned during the burning of the oil, further comprising extinguishing the burning by submerging a portion of the sorbent material or by raising the sorbent material out of the water to break contact between the sorbent material and the oil. 11. The method of claim 1, further comprising confining the oil using a boom assembly, and wherein the placing step includes locating the sorbent material amidst the confined oil. 12. The method of claim 11, wherein the confining includes: providing boom segments;connecting the boom segments to form the boom assembly; andconnecting ends of the boom assembly to enclose the oil, and wherein the locating step includes connecting the sorbent material to the boom assembly to position the sorbent material. 13. The method of claim 8, wherein the sorbent material is at least one of mineral wool or nano fiber materials or ceramic fiber material. 14. The method of claim 1, wherein the sorbent material resists burning and melting when exposed to a temperature of about 700° F. or higher for one minute. 15. For an aquatic environment in which there is one or more types of oil, an in-situ burning device comprising: a fire-resistant sorbent material configured to wick the oil for a flame, wherein the sorbent material includes fibers of sufficient size to be respirable, and wherein the sorbent material resists burning and melting when exposed to a temperature of about 700° F. or higher for one minute; andan active aeration system configured to inject air into the sorbent material. 16. The device of claim 15, further comprising a fire-resistant ligature binding the sorbent material into a bale. 17. The device of claim 15, wherein the sorbent material is coupled to a frame, and wherein an elevation of the frame, relative to a surface of the water, is controllable to thereby adjust the combustion process of the oil. 18. The device of claim 17, further including a buoyancy system mounted to the frame, wherein a buoyancy of the buoyancy system is adjustable to thereby control the elevation of the frame. 19. The device of claim 15, wherein at least part of the sorbent material is coated with at least one of an oleophilic material, an oligophilic material or a hydrophobic material. 20. The device of claim 15, wherein the sorbent material is positioned on an aquatic surface on which floats the oil, wherein the oil is being burned and the sorbent material is in contact with the oil and acting as a wick as the oil is burned. 21. For an aquatic environment in which there is one or more types of oil, an in-situ burning aerated wick comprising: a fire-resistant sorbent material configured to wick the oil; anda pipe including a vented segment disposed in the material whereby air is suppliable through the at least one pipe and out of the vented segment to thereby aerate the material. 22. The wick of claim 21, further comprising an air pump or other fluid supply device operatively connected to the pipe. 23. For an water environment in which there is one or more types of oil, an in-situ burning device comprising: a fire-resistant wicking bale including: a fire-resistant sorbent batt configured to wick the oil; anda fire-resistant ligature binding the batt into a bale;a frame to which the bale is mounted; andat least one pipe, the at least one pipe including a vented segment having a plurality of vents therein, each vented segment being disposed in the batt whereby air can travel through the at least one pipe and exit the vents to thereby aerate the batt. 24. The device of claim 23, further comprising a source of pressurized air operatively connected to the at least one pipe. 25. The device of claim 24, further comprising a buoyancy system, mounted to the frame, configured to selectively raise or lower the batt relative to a surface of the water. 26. The device of claim 25, wherein the buoyancy system is configured to move the batt between a first position in which that the batt is positioned entirely above and out of contact with the surface of the water, and a second position in which the batt is in contact with the surface of the water. 27. The device of claim 25, wherein the oil is a layer floating on the surface of the water, and the buoyancy control system is configured to selectively submerge a part of the batt to a depth comparable to a thickness of the oil layer. 28. The device of claim 25, wherein the buoyancy control system is configured to selectively submerge a portion of the bale sufficient to extinguish combustion of oil being wicked by the batt. 29. The device of claim 15 wherein the sorbent material is made of at least one of stone wool or nano fibers or rockwool or mineral wool or slag wool or ceramic fibers.
