Sending directed sound beams is important to so many needs and luckily we are getting better at creating ways to do this. Perhaps in the future we can send sound waves thru tunnels of other waves to further enhance the capabilities of the sound waves.

For instance what if we use directed lasers in a pentagon formation and then send the sound in between the laser beams. We would be able to change all the normal dynamics of what sound does naturally and we may find that we can use this technique to develop many new important applications for the sound waves this way.

Consider for a minute if you will the possibilities of sending acoustic directional sound waves inside a group of light waves underwater? But why you ask? Well perhaps you wish to take out an incoming torpedo or send a shock wave blast into an enemy submarine, which is threatening your ship convoy or fleet.

What if you wished to use sound propulsion via light waves for some purpose? By mixing sound and light waves, which are either trained beams or directional in nature we may find that there are no limits as to what we can do with them. And thus perhaps we should be thinking on this in 2006.
