Abstract:
1. A soil-remediation device for remediating soil of an area of land, said device comprising: an outer member that includes an outer surface of the device, wherein the outer member comprises a first thermally conductive material; a tubular member through which a fluid may be circulated in and out of the device such that if the device is in contact with the soil then heat is transferred from the fluid to the soil by being transferred from the fluid to the tubular member, from the tubular member to the outer member, and from the outer member to the soil, wherein the fluid in the tubular member is at a higher temperature than is the soil in contact with the device, wherein the tubular member comprises a second thermally conductive material, and wherein the outer member surrounds the tubular member; a plurality of springs within an interior space of the device such that the plurality of springs applies a force to the tubular member to facilitate direct physical and thermal contact between the tubular member and the outer member, wherein the tubular member surrounds the interior space and the plurality of springs; and a plurality of vent holes in the outer member, such that if the device is in contact with the soil then a gas may flow through the vent holes from the soil to the interior space or from the interior space to the soil.
