Sound Generator Lethal From 10 Meters

penguinrecorder writes "The Thunder Generator uses a mixture of liquefied petroleum, cooking gas, and air to create explosions, which in turn generate shock waves capable of stunning people from 30 to 100 meters away. At that range, the weapon is relatively harmless, making people run in panic when they feel the sonic blast hitting their bodies. However, at less than ten meters, the Thunder Generator is capable of causing permanent damage or killing people."

Things harmless at range can kill at contact distance. That's why some blind people with licenses to carry concealed handguns use blanks.

Umm. Fully blind people can get CCWs? They can fire live rounds? I suppose I can see why the 2nd ammendment allows for that, but still, wtf America.

They're blind, not stupid or irresponsible. Blind people are perfectly capable of understanding the risks and potential consequences of using a firearm for self-defense. Granted that it's much more difficult for them to use a gun safely and effectively, but those obstacles are no more insuperable than many others a blind person faces. Obviously, they would only use their gun on an attacker at contact distance, and the idea of using blanks is to prevent innocents from being injured by overpenetration, since the blind person may not know who or what is on the other side of their target.

Personally, I wouldn't recommend blanks for that application. I'd recommend frangible bullets, or perhaps just a relatively light powder charge in a large caliber cartridge with a reliably-expanding jacketed hollowpoint. Blanks fired into the chest are unlikely to stop a determined attacker. On the other hand, 95% of firearms self-defense incidents don't involve a shot being fired at all -- the attacker sees the gun and runs away -- so blanks would work fine. With blanks, you could even fire a "warning shot" (NOT a good idea with real ammunition) to make the point that you're serious, which would probably raise the likelihood of the bad guy turning tail another percentage point or two.

Oh, and to answer the first question: Yes, in most states. A handful (e.g. Nevada) have range requirements that would be hard for a blind person to meet. Then again, there may be exceptions in the laws, or ways around them for disabled people.

How fast?

According to company data, the system generates 60 to 100 bursts per minute, each traveling at about 2,000 meters per second and lasting up to 300 milliseconds.

It is pretty impressive they can make a burst of sound move at six times the speed of sound.

Re:Permanent damage at 100 meters too...

You have to see it to understand it. http://www.youtube.com/watch?v=am12NZwr3Fk Vortex cannons send out a spiraling ring of air. They can hit people and things with some serious force, but it's not due to sound.

Because then the people who spent their resources on developing new ways to kill use those innovations on the people that didn't.

Nope.

Genocide is really rare. Invasion, colonization and assimilation is a lot more common.

Killing people is almost entirely pointless. Threatening to kill people is what does the job, because people happen to be wired in ways that let them be controlled up to a point by such threats. When the threat level becomes too high they always fight back, of course, because they happen to be wired that way, too.

Gandhi's big trick was to realize that death threats are not generally credible, and react accordingly, which means not allowing your behaviour to be controlled by threats, and being willing to die rather than submit. There are specific circumstances where that won't work at all--such as the Jews in Nazi Germany--but in almost all cases peaceful, active resistance is far more effective.

These weapons, as others here have pointed out, are aimed at Gandhi-style tactics: by having a non-lethal response to a peaceful, active resistance it tilts the tables back toward the oppressors, who are basically engaging in mass instantaneous public torture-at-a-distance via the use of these weapons.

These weapons are designed to generate compliance with the alpha chimp's wishes by engaging people's pain response rather than their fear response. The latter can be fairly easily subverted, depending as it does on a vague cognitive connection between threat and outcome. The former is much tougher nut to crack, although it'll be interesting to see the first time the cops are on the receiving end of one of these weapons, which will no-doubt be reduced to hand-held form factors in the next couple of years.

Non-lethal is perhaps a greater threat

[G]overnments have been looking for "non-lethal" crowd control devices like this [...]

I actually find this worrisome, from the standpoint of civil liberty. Non-violent protest actually relies on the brutality of governmental response to provoke sympathy and garner support for one's cause. While the so-called "non-lethal" weapons of today are still pretty brutal, I invite people to follow me on a little thought experiment that illustrates my concern.

Let's carry non-lethal crowd control methods to their ultimate conclusion. Imagine a device that lulls people to sleep, whereupon they're carried home, placed in their beds, enjoy a night's rest like the haven't managed in months, and awake to find a chocolate morsel on their nightstands and a terrifically refreshed sense of well-being. If crowds of peaceful protesters are broken up by repressive governments using this device, how much sympathy will that garner? How effective will civil disobedience be?

The scenario I describe is purposefully fanciful and exaggerated. Nevertheless, my point is that non-lethal methods carry the very real threat of keeping bad governments from looking all that bad. Government should hurt; and repressing civil disobedience should carry the risk of looking bad. Otherwise, you can be sure it will be used at the drop of a hat. And that may just pose a problem.
