50 7 Full Breakdown

Summary

Story summary

Researchers at Lawrence Berkeley National Laboratory developed ionocaloric cooling, a refrigeration method that uses ionic motion instead of traditional refrigerants to help meet climate goals.
The ionocaloric cooling device operates with no moving parts and can rapidly heat or cool.
Experiments showed a 25 degrees Celsius temperature difference using a salt made of iodine and sodium.
The findings were published in the journal Science.
