Summary

Story summary

Lawrence Berkeley National Laboratory (LBNL) and the University of California, Berkeley researchers have developed ionocaloric cooling.
The method uses charged particles to shift materials’ melting points, enabling cooling without refrigerants.
Experiments show a 25-degree Celsius shift with minimal energy input.
The findings indicate improved efficiency, reduced global warming potential, and support for hydrofluorocarbon reduction commitments.
