I’d like to see this sort of technology incorporated into power tools. Instead of lugging around a 15 lb worm drive Skilsaw, it would be a 5 lb laser saw with a 12 inch cut depth. Or instead of using a heavy and noisy chainsaw, how about some kind of light saber like tool for cutting down trees or bucking up firewood. How about a laser drill press or hand held “drill” using lasers.While their at it, make laser machetes. They could market them as "light sabers."
