Lasers can cool water! Truly speaking, I had never imagined anything like this can happen. Science and its mysteries are not only astonishing, but it also takes your breath away at the point when you understand it. Initially, it was known that Lasers can be used to heat water, but a research done at the University of Washington has revealed that Lasers can be used for cooling down water as well. The new study has been published in the Proceedings of the National Academy of Sciences.
According to the reports, the scientists have devised a way by which Lasers can be used to refrigerate liquids, when outside a Vacuum. Dr. Peter Pauzauskie had initially stated that they were not sure of the cooling possibility as Laser illumination is known to heat up water bodies. The primary example of this is the act of Global Warming that has been a pain of all sorts for scientists and environmentalists.
This is not the first time, when such a proposition has come through. In the 1995, scientists had devised a way to cool liquids with Laser beams. But that process required liquid to be kept in a vacuum, which is literally devoid of any practical application. But in this scenario, scientists are hopeful of drawing out a few practical applications as the limit of a vacuum has been erased.
To be true, if the laser can seriously be used to cool down water, then my random thoughts suggest that it can come to a great aid for Global Warming. The UV Rays are one of the primary reasons of Global Warming. More research is needed in the area and then only it would be plausible to make stronger statements in this regard. This could also have application in biological research, where in separate molecules can be treated with Lasers for the study.
