Say hello to ionocaloric cooling.
It's a new way to lower temperatures with the potential to replace existing methods of chilling things with a process that is safer and better for the planet.
Raise the temperature on a block of ice, it'll melt. What we might not see so easily is that melting absorbs heat from its surroundings, effectively cooling it. The researchers modeled the theory of the ionocaloric cycle to show how it could potentially compete with, or even improve upon, the efficiency of refrigerants in use today. A current running through the system would move the ions in it, shifting the material's melting point to change temperature.The team also ran experiments using a salt made with iodine and sodium to melt ethylene carbonate.
