Abstract

The present invention provides a method of drawing a thermoelectrically active material (22) in a glass cladding (14), comprising sealing off one end of a glass tube (14) such that the tube (14) has an open end and a closed end, introducing the thermoelectrically active material (22) inside the glass tube (14) and evacuating the tube (14) by attaching the open end to a vacuum pump, heating a portion of the glass tube (14) such that the glass partially melts and collapses under the vacuum such that the partially melted glass tube (14) provides an ampoule (54) containing the thermoelectric material (22) to be used in a first drawing operation, introducing the ampoule (54) containing the thermoelectric material (22) into a heating device (10), increasing the temperature within the heating device (10) such that the glass tube (14) melts just enough for it to be drawn and drawing fibers (24) of the glass clad thermoelectrically active material (22).

Description

technical field [0001] [0001] The present invention relates to high density nanowire arrays in a glassy matrix and methods of stretching the same. Background technique [0002] [0002] Thermoelectric materials generate electricity when subjected to thermal gradients and create thermal gradients when electrical current flows through them. Scientists have been trying to harness practical thermoelectricity for decades because practical thermoelectricity could: (1) replace the fluorocarbons used in existing refrigeration systems such as refrigerators and air conditioners; and (2) convert some or most of the waste heat into reduce harmful emissions during thermal power generation; and other effects. Yet the promise of practical thermoelectricity has yet to materialize. One problem is that due to its low efficiency, the industry standard in thermoelectric technology cannot be functionally incorporated into everyday heating and cooling products and systems.
