Abstract: Systems and/or methods can provide for solid-state refrigeration below 1 degree Kelvin. By applying a simple sequence of ac electrical signals to a gated semiconductor device, electrons are cooled in a refrigeration sequence that, in turn, provides cooling directly to the heat load of interest. Electrons in a single subband of a semiconductor quantum well are expanded adiabatically into several subbands, resulting in a temperature drop. Repeated application of this cycle at MHz-GHz frequencies results in a significant cooling power. The anticipated cooling powers can compete with today's standard cryogenic system, the dilution refrigerator, which represents the market standard for achieving cryogenic temperatures.

Abstract: This invention relates to temperature control of hot beverages served in mugs/cups. It is particularly well suited for ensuring that temperatures of hot drinks can be maintained in an optimum/preferred range for long periods of time.

During use, these are be added to a drink to maintain it at a high temperature in a manner similar to ice-cubes that are used with cold drinks. A separate charger is then used to charge/recharge the heating block(s) in a non-contact manner after each use.
