Will caloric materials innovate air conditioning?

Is this just hot air or wishful thinking by the usual climate change fanatics or are we about to witness a major advance?

One thing seems to be for certain, the global demand for air conditioning is rising significantly because of improved economic prosperity in many parts of the world.

"[Researchers] placed plastic crystals of neopentyl glycol—a common chemical used to produce paints and lubricants—into a chamber, added oil, and cranked down a piston. As the fluid compressed and applied pressure, the temperature of the crystals rose by around 40 ˚C.

It was the largest temperature shift ever recorded from placing materials under pressure, at least when the findings were published in a Nature Communications paper last year. And alleviating the pressure has the opposite effect, cooling the crystals dramatically. ...
In addition to reducing the need for hydrofluorocarbons, the hope is the technology could eventually be more energy efficient than standard cooling devices, given the heat released relative to the amount of energy needed to drive the change."
