    Perhaps we can beam an entire education into the minds of young people. Think about it. Roughly half of America's young people reach the age of 18 at being virtually retarded these days. Beaming voices into peoples' heads might be a highly useful tool.
                It also might be used to teach people what Islam really is in places like Iraq where an entire religion has been subverted and perverted into a really nasty mess. Teaching real Islam to the public might cure this problem.

    Two myths I want to debunk right off the bat.

    Great! I love to see myths debunked.

    the spectrum that your microwave uses happens to cause water molecules to resonate. These microwaves are of a different spectrum, and while they can be deadly, they are not the same.

    ... unfortunately, that's one of them. The 2.4GHz spectrum was not chosen because water molecules somehow resonate better - and there's no real difference between 2.4GHz and various mobile frequencies around 1.8-1.9GHz with that in mind.

    And friend of mine has a couple of these speakers. We recently used them at an art opening to beam the music of the primes into people's heads (playing the digital root of each prime number through a hexatonic scale, rests in the music were created by the occurrence of the primes in the digital-roots matrix we used to develop our own unique prime number sieve).

    I see enormous benefits in this technology.

    1. Listening to music as loud as you want while not forcing it on others
    2. Rocking out to the loudest concert in history without anyone outside the venue hearing a whisper of it (on second thought, the RIAA might require this, so maybe it's not so good)
    3. Throwing a gigantic party with great tunes while letting the geezer next door -- who never listens to anything harder than Captain and Tennille -- get his beauty sleep

    I think there's a similar effect that explains the "whooshing" sound you hear when you watch shooting stars.

    For years, scientists have believed that the sound was a figment of human imagination, even though many people would swear to hearing it. The problem is that the meteors are miles and miles overhead, but the sound is heard simultaneously. Now I've personally heard the whoosh of a bolide during a the massive meteor shower, and I'd be prepared to swear it was simultaneous with the flash of the meteor trail, even though I know that sound could not travel that fast, even if it were a mere few thousand feet.

    It's even more psychologically convincing because the sound isn't really a "whoosh"; it's not what you'd expect. It's more like the sound of slurping the last bit of milkshake with a straw, listened to through a long PVC pipe.

    I read a few years ago that physicists found an accoustic effect created by the low frequency electrmagnetic energy working on water droplets of a certain size. This would make sense because when I did hear the "whoosh", I was lying on my back on the dewy grass. I've also read that wireframe glasses can account for the simultaneous sound.

    Obviously, you should run a wire from your tinfoil hat to a conductive grounding strip attached to the heel of your shoe.

    Actually, the devices I've used connect to the toe of your shoe, not the heel - Both heels are often lifted while walking. And you need to be sure that you run wires to both feet instead of just one. Also, unless you have a conductive floor (we did when we were using these, but for a very different purpose), spikes are more effective than strips. But you need to plan for the terrain. 1/4" spikes are fine for walking (and very effective for grounding) in damp vegetation or earth but may impede your progress on asphalt. In that case, you'll need very shallow spikes and will just have to accept limited grounding unless you're willing to run a very long cable to a copper rod.

    As a deaf guy it saddens me when tech like this is used for military purposes and it's consumer uses are not considered.

    Remember the thing where you put the transmitter on your tongue and you can hear bypassing the ears? I'd like to try one of those. But rather than look like a drooling idiot I'd love to get my hands on one of these babies. Just strap it on a hearing aid and skip the ears entirely. Way better than a cochlear implant, non-invasive and perfect sound. Nice.

    Yeah!! Get rid of all these taser and microwave weapons. Bring back good old night sticks, trunchons, jack boots, and guns. It's a lot easier to prove that victims were hurt by those weapons than by tasers or microwaves. Or their own decisions to resist arrest or not leave buildings.

    Hmm...

    Now avoiding TFA like the plague, it occurs to me that "shockwaves" within the skull able to cause hydrostatic pressure loads comparable to 120+ decibels (is that loud enough for ya?) hitting your eardrums might just damage something other than eardrums.

    But lets not even think about the fine possibilities such as massive damage on the cellular level - just consider the overpressures that could be set up within blood vessels. It will be interesting to see if there is any increase in "massive cerebral hemorrage" as a cause of death going forward.

    Or an increase in the wearing of hats by the political class anytinme they give a speech :)

    ...up until recently, generations of police officers learned how to use physical force to gain compliance. And generally speaking they knew how to do it with minimal force and maximal compliance -- a friend who is a 2nd generation police officer had his father demonstrate some of the techniques, and it was fairly amazing how well he could hurt me without actually "hurting" me (ie, leaving lasting marks, breaking bones, bruising, etc.)

    The gripe my friend the cop has is that with all the touchy-feely policing (and the expensive court payouts) they have, you really can't gain compliance through physical force the way you used to be able to, so they are largely left with their guns and their tasers. And since the tasers aren't lethal, they're somehow considered "OK" to use for any problem solving short of killing someone.

    I think they should start allowing the police to carry saps and clubs again as well as teach them physical force and stop letting them use a taser as a universal problem solver.

    A Taser was designed to replace a gun.

    Although I agree with your overall point that Tasers are seriously overused, your initial premise is incorrect.

    Tasers were never intended to be used as a replacement for a gun. They are an additional non-lethal weapon to use alongside the baton and pepper spray.

    Unfortunately, politicians and even the police themselves use the "Tasers replace guns" myth to win people over to the idea. After all, who wouldn't prefer to see a Taser used instead of a gun?

    But that's not what happens. When the situation calls for a gun to be used, then the officer will use their gun. Period. They will never consider using the Taser instead, and they were never expected to. This is why the number of incidents involving police using their guns has not decreased since Tasers were introduced. Nor was it expected to.

    The problem is that Tasers seem really harmless. You press a button, and the guy falls to the floor. Shortly thereafter, he gets up and he's apparently fine. So, hey, why not use it even in cases where the use of a baton or pepper spray would cause mass outrage?

    And that's exactly what's happening now.

    That's one of the things that the guy selling the thing (in TFA) mentioned, actually.

    My understanding:
    This device creates vibrations in the target by rapidly heating and cooling it. Since these vibrations are in the tissue (especially bone) of your head, they reach your inner ear (cochlea) directly. So, they could help with certain kinds of deafness: namely, deafness caused by mechanical damage to the outer ear, but which leaves the nerves in the inner ear intact.

    However, it seems you should be able to achieve exactly the same thing by sending acoustic waves through the skull by other means. In particular, all you need is a small speaker in direct contact with your head. That's exactly what certain existing hearing aids do. (See the Wikipedia article on Bone conduction [wikipedia.org] for more.)

    Hence, my opinion is that this microwave device really doesn't have any good uses which are not more easily and safely achieved by other means.

    Unfortunately it looks like this will only work if your inner ear is undamaged and functioning properly. I had major hearing loss in one ear from an injury a few years ago, and one of the tests they did was acoustically coupling a small vibrating pad to the base of my skull to determine whether the injury was in the middle or inner ear. If your cochlea are already damaged to the point that you need a cochlear implant (direct neural stimulation) then you'd be able to _feel_ your skull vibrating but you will hear nothing -- a very odd sensation indeed.

    Of course I shudder at the thought of what microwave radiation would do to the electrodes in your cochlear implant. It might literally induce a current through your brain. At the low end it would destroy the tissues connected to the electrodes. At the high end it might induce a seizure or kill you. I hope to hell it's well shielded.
