Prototype heat pump uses electric fields and ceramic instead of refrigerant fluid

Prototype uses electric fields and a special ceramic instead of alternately vaporizing a refrigerant fluid and condensing it with a compressor to warm or cool air.

The technology combines a numbe last week ting Science ques and has "superlative performance," says Neil Mathur, a materials scientist at the University of Cambridge, UK.
