digg_url = 'http://digg.com/gadgets/How_It_Works_The_Airborne_Laser_Cannon'; Creating a laser that can melt a soda can in a lab is a finicky enough task. Later this year, scientists will put a 40,000-pound chemical laser in the belly of a gunship flying at 300 mph and take aim at targets as far away as five miles. And were not talking aluminum cans. Boeings new Advanced Tactical Laser will cook trucks, tanks, radio stations—the kinds of things hit with missiles and rockets today. Whereas conventional projectiles can lose sight of their target and be shot down or deflected, the ATL moves at the speed of light and can strike several targets in rapid succession.
If the laser is emitting visible light only, what would happen if it hit a prism? Would you get a rainbow of lasers burning away in every direction? Also, if a tank is painted white or a mirror chrome, will the laser be reflected?
Eggs used to be in the news all the time. One month they were good for you, the next month, bad. Morning talk shows and television commercials would trot out expert after expert to volley the conflicting health claims back and forth. But while there is a legitimate debate over the cholesterol content of egg yolks and whether that cholesterol is ultimately bad for you or not, the analogous debate getting airtime these days is not much of debate at all: whether cellphones cause brain cancer.
DracosGame, I don't believe that's true. Microwaves have a lower frequency than visible light, and yet they can cause harm to the human body. I'll wager a few bucks that if you microwaved your head, you would recieve, if not cancer, at least brain damage.
