University of Washington researchers say they used a laser to turn hot water into cool water.Five engineers from the university are the first in the 50-year history of the laser to refrigerate liquids under normal conditions with light beams.The group used a simple approach to the experiment. Lasers are known for producing hot temperatures. The University of Washington says they “essentially ran the laser phenomenon in reverse.”
The discovery has a future in the computer and medical fields. Computer interiors could be cooled by lasers. In a medical laboratory, individual cells could be cooled to see how they react. “Few people have thought about how they could use this technology to solve problems because using lasers to refrigerate liquids hasn’t been possible before,” said researcher Peter Pauzauskie.
