Sea Pirates

[Mr. Security]

Did anyone see the 2-hour program that recently aired on TV regarding the increasing problem with modern-day pirates robbing or taking over vessels at sea? One ship used an unusual non-lethal countermeasure to stop the attack. The device concentrates sound waves at the pirates, making it impossible for them to continue the attack. I like it!!

Something else we won't be allowed to have in Canada

I forget the name of this thing, but NYPD has the thing mounted on a Hummer, as well as a few other agencies for civil disturbances.

I would have enjoyed seeing that show, sound waves are being looked at for many uses. Besides that countermeasure listed above, sound waves can be used to detect foreign substances in liquids. Something about an electromagnetic pulse/sensor that can figure out the liqiuds property. Acoustic interferometry, if you want to do a google.

The story I read listed a possible use as confirming what is in the coffee cup you are holding while in line at the airport.

They have been working on sound and radio wave non-lethal weapons for a long time now. The navy recently tested an underwater system that uses multiple "speakers". Although each "speaker" was harmless they could be focused in a way that the percussion from the sound wave would hit an object at the same time causing it to be destroyed. They were testing this for harbor security against, mines, torpedoes, divers, etc.. I have heard that DARPA (Defense Advanced Research Projects Agency) is testing a system like that for defense. They are trying to get to the point where they can focus the energy on one person in a crowd and not bother anyone around the target. There have been numerous advances in non-lethal technology over the past 10-15 years.

Did anyone see the sticky foam gun they made a few years ago? It worked to subdue someone but was hell to clean up. Not very practical.

Any idea what that would do to someone with hearing aids?

Let's hope that grandma and grandpa are engaged in some other lawful activity.

I'm sure that they will air it again. Another facet to this technology is the use of pulsating lights/certain odors that cause severe nausea. I don't know anyone who can resist once the nausea becomes intense. It will bring a criminal down to the ground.

Hearing aids only amplify certain frequency ranges.

The energy from each "speaker" that is focused has a real low, or high frequency that by itself may only cause minor discomfort. When the other beams of a "slightly" different frequency converge at the focal point it becomes more than uncomfortable. It may cause loss of bodily functions , and severe pain. .So far I've only seen write-ups about it in Janes Defense and other military and technology stories. I've heard there is a video of a test out in cyberworld some where. Here's a list of links on the subject from the Air force.

I like the old fashion way. Sink their ship and hang the pirates

yeah, it sounds like there is some good merc work to be done on the high seas. hunting pirates and saving cruse ships... all for a price of course.

what would jack sparrow do? LOL

Time for the government to start issuing Letters of Marque again.

The certification for marine employment is highly regulated on commercial vessals. Piracy is not limited to commercial vessels or deep water. Coastal piracy, off Central and South America, Africa and South East Asia is a major issue. Private vessels and private security are not regulated. Local firearms laws and customs regulations apply.

The program emphasized that firearms are not permitted when operating in international waters. A vessel is required to hire an expensive security escort if they want armed protection. Another interesting dilemma is that corruption is rampant in local navy/police forces that have jurisdiction in certain territorial waters. It's not uncommon for crewmembers that have been victimized to recognize some members of the police as being part of the raiding party the previous day.
