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."
Just firing a handgun without hearing protection is enough to rip out the hair cells in your ears (which don't grow back) and cause permanent hearing loss. I'm pretty sure that if this thing is capable of "stunning" people it's doing lasting damage to your auditory system. That damage may be small, but it remains that the ringing you hear in your ears afterward is still a set of frequencies you'll never hear again.
Yet again, OP gets it a little bit wrong, but in this case you can't blame the poster because TFA states it wrong as well. LPG is short for for Liquified Petroleum Gas, and it IS "cooking gas", it isn't "mixed with" cooking gas. Jeez. LPG is usually propane or butane or a mixture of them.
Having stated that, I will add my voice to what others have already posted: this device is a disaster waiting to happen. It has no place in "positive" enforcement scenarios. It might be useful as a self-defense weapon, but I question even that.
This is not the only sound based non-lethal weapon used by the IAF. They also use a device called The Scream, which emits a sound that causes disorientation and nausea. This one works at low, inaudible frequencies that vibrate the internal organs of the targets. There is also an high frequency version that is audible, that also produces a burning sensation on the skin (but does not produce any permanent damage).
I think they were also toying with using these types of weapons against the pirates in Somalia.

Yes, the detonation can be faster than the speed of sound but the resulting sound only propagates at the speed of sound.
To get those bursts to propagate to the target at supersonic rates there would have to be combustible gas all the way from the device to the target.
A jet fighter going at mach 2 carries with it a sonic boom traveling at 6 times the speed of sound.
When it passes overhead at an altitude of 6k feet, you see it pass and you hear it 6 seconds later.
The sonic boom travels at mach 2 only because the fighter goes at mach 2, the sound propagates perpendicular to the fighter only at the speed of sound.
The left lane is for passing - you do not drive in that lane for any period of time or at any speed, unless passing. Why don't more people know/respect this law?
Probably because it's not a law, at least not in my state(MD).
Check before you rant
That's meters, cap'n. For the effect, I'd say it is a little more devastating than a grenade, though less practical (for now).
Have you read the page you just quoted? Below the table appears:
The Uniform Vehicle Code states:
Upon all roadways any vehicle proceeding at less than the normal speed of traffic at the time and place and under the conditions then existing shall be driven in the right-hand lane then available for traffic ...
Note that this law refers to the "normal" speed of traffic, not the "legal" speed of traffic. The 60 MPH driver in a 55 MPH zone where everybody else is going 65 MPH must move right. Contrast Alaska's rule, 13 AAC 002.50, allowing vehicles driving at the speed limit to use the left lane, and Colorado rev. stat. 42-4-1103, prohibiting blocking the "normal and reasonable" movement of traffic.
Emphasis is mine. It's almost as if the author of that page is responding directly to your GP post...
"California Penal Code Section 417.25
...the interesting part of this being in sec. a:
(a) Every person who, except in self-defense, aims or points a laser scope, as defined in subdivision (b), or a laser pointer, as defined in subdivision (c), at another person in a threatening manner with the specific intent to cause a reasonable person fear of bodily harm is guilty of a misdemeanor, punishable by imprisonment in a county jail for up to 30 days. For purposes of this section, the laser scope need not be attached to a firearm.
(b) As used in this section, "laser scope" means a portable battery-powered device capable of being attached to a firearm and capable of projecting a laser light on objects at a distance.
(c) As used in this section, "laser pointer" means any hand held laser beam device or demonstration laser product that emits a single point of light amplified by the stimulated emission of radiation that is visible to the human eye."
"...except in self-defense..." which might imply you can defend yourself with a laser...! Or a laser equipped shark...
