Actually, the lasers use a very low wattage generator of the like you can get at Radio Shack. This impulse is them amplified by successively sending the pulse through amplifiers until the final 500+TW is achieved. --Ron

I run a ton of christmas lights (installed 4 20amp circuits for the 'show') and run many strands of mini bulbs and lawn cr*p off of each one of the circuits.
The Dark Tower series is my all time favorite series of books and I have read them all multiple times.
