Abstract
A device and method for generating heat employs a heating element which is resiliently compressible or in which the electrical resistance can otherwise be varied, for a given electric current, to vary the level of heat generated. In a specific embodiment the device employs a plurality of layers of electrically conductive cloth material, for example, carbon cloth, disposed between electrodes; adjustment of the spacing between the electrodes alters the degree of compression and the electrical resistance of the plurality of layers whereby the level of heat generated for a given electric current can be varied.
