Peltier modules, or thermoelectric modules ... in improving the power efficiency of these modules. "We developed a new type of cooling for refrigerators in which the compressor and semiconductor ...

The prototype uses a Peltier effect module to get three cans down to 11 C (52 F), with a final goal of reaching 5 C (41 F). It’s not all fun and games either — [Ethan] provides a suggested ...

Peltier modules are a great solution for moving heat from one surface to another, but they are not terribly efficient at it, especially if you don’t keep the hot side temperature in check.
