I came across this article about a company using a microwave ray gun to beam noises directly into peoples’ heads and it stopped me cold.  I mean after reading these paragraphs tell me you can’t think of some amazing applications for this technology:

A US company claims it is ready to build a microwave ray gun able to beam sounds directly into people’s heads.

            
       
   
       
            
            
               

The
device – dubbed MEDUSA (Mob Excess Deterrent Using Silent Audio) –
exploits the microwave audio effect, in which short microwave pulses
rapidly heat tissue, causing a shockwave inside the skull that can be
detected by the ears. A series of pulses can be transmitted to produce
recognisable sounds.

            
       
   
       
            
            
               

The device is aimed for military or crowd-control applications, but may have other uses.

            
       
   
       
            
            
               

Lev
Sadovnik of the Sierra Nevada Corporation in the US is working on the
system, having started work on a US navy research contract. The navy’s report states that the effect was shown to be effective…

Sadovnik says the technology could have non-military applications.
Birds seem to be highly sensitive to microwave audio, he says, so it
might be used to scare away unwanted flocks.

            
       
   
       
            
            
               

Sadovnik
has also experimented with transmitting microwave audio to people with
outer ear problems that impair their normal hearing.

I’m sure that many people would instantly think of noble uses for this technology, for instance helping the hearing impaired.  Me?  The first thought I had was how much fun it would be to mess with people with this thing.  Have a boss you can’t stand?  Think of the turmoil you could cause him by beaming things like, "This is God.  I am preparing to smote thee for being such a jerk to fill in your name and anyone else you like at work.  Your only chance at redemption is giving them annual 20% raises.  Oh, and I’m thinking of another flood so I need you to head to Home Depot to start your ark preparations."  If you do this a couple of times a day for a week you’ll either be rid of the jerk after he checks himself into the hospital or you’ll have a much fatter pay check.

Lest you think I’m truly disturbed I won’t tell you the things I thought of that I could beam to my kids.
