The Backpack Laser cleaning system from Clean Laser is billed as the "world's first backpack cleaning laser." It's a self-contained system that uses a powerful industrial laser to clean and restore surfaces. However, I'm thinking that with a little imagination, you might be able to figure out some alternative uses that would be more fun - like maybe hunting ectoplasmic entities ala Ghostbusters.
Here's what the company has to say about the backpack laser (see photo):
If I had one of these, I might be tempted to see if it had any utility in attacking negatively charged ectoplasmic entities ala Ghostbusters. See the proton pack for a picture and explanation of the fictional device, which bears more than a passing resemblance to the real life backpack laser.
However, since Clean Laser Systems does not offer a ghost trap, I wouldn't have anyplace to hold any entities I caught with it. Hopefully, this gap in their product line will be filled soon.
If there are more than one of these backpack lasers in existence, I certainly hope that the manufacturers warn users "not to cross the streams."
