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.
I can verify that this is indeed feasible. I have myself performed exploratory operations on a number of ants and other selected insects using concentrated sunlight.
If I seem short sighted, it is because I stand on the shoulders of midgets
