Screens are so troublesome. You have to clean them often in marine
areas, and they get holes in them, so you have to replace them, or put
a panty-hose patch on them. What we need is a solution that doesn't
require the cleaning of a screen! Lasers would work perfectly for this!
We've all seen
the oscillating laser scanners at the checkouts, but boost
the power up on these puppies and you've got yourself a bug/rodent
zapper! the frame for this would be mirrors so that it would bounce
the laser many times. Get the oscillations going fast enough and you
only need to turn the intensity up when you detect something in the
laser path. Once it detects something, it immediately pumps the
power up and slices that mosquito clean in half.
