The principal feature of this device is that the water is heated and cooled using Peltier elements, allowing a very wide temperature range, from below ambient temperature (0 °C) up to 100 °C ...

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, or thermoelectric modules, are thermal control devices that provide both heating and cooling effects, maintaining the surface temperature at a set target. These modules are ...
