Abstract

A system for reducing energy usage in a heat controlled device comprises a transparency adjustment device (TAD) including a transparent physical element whose electrical behavior is that of a capacitive load and a power dimmer apparatus operative to provide AC current to the transparent physical element to generate a set of transparency states between opaque and full transparent. The system also comprises a heat control device including a closed walled cavity and a thermometer adapted to control temperature in the cavity. The TAD is embedded in at least a portion of the cavity wall. The TAD reduces the thermometer energy consumption by enabling view of the cavity content without opening the cavity.
