Instead of shooting a single burst of beam, use multiple shots ( say 1000 per second or more ) Theoritically each laser beams should punch a hole through the air, each one travelling further and each one creating a vacum within its path. The high powered lasers that auto industries use have effective range of only 2 inches I believe, which they use for cutting sheet metal in assembly line for making cars. Maybe it is possible to program it to do a multiple bursts at a single point and see what happens. Just a thought thats been stuck in my head since 1990. I'am not a scholar, I don't have a degree in anything. So did all the greatest scientists in our history have a "degree" in those fields in which they were famous in?
