Say hello to ionocaloric cooling. It's a new way to lower temperatures, with the potential to replace existing chilling methods with a safer, better-for-the-planet process. Typical refrigeration systems transport heat away from a space via a fluid that absorbs heat as it evaporates into a gas, which is then transported through a closed tube and condensed back into a liquid. As effective as this process is, some of the choice materials we use as refrigerants are particularly unfriendly to the
