20130094909 | SYSTEMS AND METHODS FOR COLLECTING AND PROCESSING PERMAFROST GASES, AND FOR COOLING PERMAFROST - Systems and methods for collecting and processing permafrost gases and for cooling permafrost are disclosed herein. A method in accordance with a particular embodiment for processing gas in a permafrost region includes obtaining a gas from a sacrificial area of a thawing permafrost region, dissociating the gas in a non-combustive chemical process, and circulating a constituent of the gas through a savable area of the thawing permafrost region to cool the savable area. In particular embodiments, this process can be used to cool selected areas of permafrost and/or create clean-burning fuels and/or other products from permafrost gases. | 04-18-2013 |
20140133918 | LAWN GRID - A lawn grid is provided with pipelines for a heat transfer medium. By using this lawn grid, a turf which can be used for summer operation can be integrated in winter into the structure of an artificial ice rink and/or the turf can be kept free of frost in wither by means of a surface lawn heating. Moreover, the lawn grid can be used for the active and passive recovery of solar heat. | 05-15-2014 |

20090169307 | METHOD OF PREPARING A FOUNDATION STRUCTURE - This invention provides a method of preparing a foundation structure including the steps of forming foundation trenches in the ground; and heating the ground defining the trenches sufficiently to irreversibly change the properties of the ground defining the trenches. In the case where the ground consists primarily of clay, it is heated to a temperature above a level where the ground is baked into a brick-like consistency, wherein the structural water of crystallisation is removed and any carbonaceous material and Fe is oxidised. If the ground consists primarily of sand, it is heated to a temperature above its vitrification point wherein mullite (AI | 07-02-2009 |
20100119306 | Ground thawing mat and apparatus for making same - A ground thawing mat includes at least a flexible upper sheet overlaying a serpentine twinned array of flexible heating fluid conduits, wherein the twinned array include at least a closely adjacent and parallel pair of conduits extending from a heating fluid inlet entering the parallel pairs of conduits to a heating fluid outlet exiting the parallel pair of conduits, and wherein the parallel pair of conduits extend substantially linearly without crossing one another between opposed serpentine turns. Further, the parallel pair of conduits turn through the turns without crossing one another so that the twinned array lie substantially in a single plane overlaid by the upper sheet. | 05-13-2010 |
20100322713 | MICROWAVE GROUND, ROAD, WATER, AND WASTE TREATMENT SYSTEMS - A microwave ground or road surface heating system that eliminates the need for preparation of the surface to be heated while preventing leakage of microwave radiation. The highly portable microwave heating system prevents leakage of microwave radiation via a microwave horn and sealing shroud configuration that seals the unit to the surface being heated. | 12-23-2010 |
20150292298 | GEOTHERMIC HEATER SYSTEM - A geothermic heater system for heating a geological formation includes a fuel cell stack assembly disposed at the surface of the geological formation and includes a plurality of fuel cells which convert chemical energy from a fuel into electricity through a chemical reaction with an oxidizing agent, thereby producing an anode exhaust and a cathode exhaust. The geothermic fuel cell system also includes a combustor disposed within a bore hole of the geological formation. The combustor combusts a mixture at least one of the anode exhaust and the cathode exhaust to produce a heated combustor exhaust. The combustor discharges the heated combustor exhaust to heat the geological formation. | 10-15-2015 |
