1. A thermoelectric cooling apparatus, comprising:

  • a first thermal sink of a first nominal temperature;

    a second thermal sink of a second nominal temperature, the second temperature being relatively greater than the first temperature;

    a thermoelectric element continuously coupled to the second thermal sink;

    means for selectively switching a thermal coupling of the thermoelectric element to the first thermal sink; and

    means for selectively switching an electrical voltage across the thermoelectric element operable independent from the means for selectively switching the thermal coupling.
