Researchers Refrigerate Liquids With A Laser

Anyone saying that this is the "first time" anyone has done this has obviously never seen that crappy 1997 Batman and Robin movie. big grin

Since the first laser was invented in 1960, they’ve almost always given off heat آ— either as a useful tool, a byproduct or a fictional way to vanquish intergalactic enemies. But those concentrated beams of light have never been able to cool liquids. University of Washington researchers are the first to solve a decades-old puzzle آ— figuring out how to make a laser refrigerate water and other liquids under real-world conditions.
