Apparatus and method for harnessing heat energy uses at least one thermally conductive material in communication with a heat collecting material in order to conduct heat from a first region of the heat collecting material to a second region of the heat collecting material. The thermally conductive material can be interspersed within the heat collecting material and/or applied externally to the heat collecting material. Heat drawn from the second portion can be stored and/or converted into another form of energy for providing power to a structure or vehicle. Conversion can use the differential between the temperature of the second region and the temperature of a cold sink. Additional heat can be added to the heat collecting material.
