Surgery Using A Sunlight Scalpel

Makarand writes "Research conducted by Israeli doctors has shown that it is possible to use concentrated sunlight instead of lasers to perform surgery, providing a safe and low cost alternative to laser treatment. In their experiments sunlight was transported into the operating room from outside using a system of optical fibers. The concentrated rays - containing several watts of energy - were then used in the experimental surgery conducted on rats." Here is Wired's similar story.
