Right? My first thought reading the title was "okay sure, the crystals get cold. Then what? Are we going to push the crystals outside so they can warm up again, ready to start the cycle anew?". How is "cold crystals" working better to transfer heat than a gas/liquid?

I should read the article, I suppose...

    I note that the article states the following: "When the pressure is removed, the process reverses, and the solid can absorb heat from the nearby environment." That would appear to be the opposite of the headline
