50 Years of Research and Still No Microwave Weapons 154
DevotedSkeptic writes in with a story about the lack of usable microwave technology to come from 50 years of military research. "For some Pentagon officials, the demonstration in October 2007 must have seemed like a dream come true — an opportunity to blast reporters with a beam of energy that causes searing pain. The event in Quantico, Virginia, was to be a rare public showing for the US Air Force's Active Denial System: a prototype non-lethal crowd-control weapon that emits a beam of microwaves at 95 gigahertz. Radiation at that frequency penetrates less than half a millimetre into the skin, so the beam was supposed to deliver an intense burning sensation to anyone in its path, forcing them to move away, but without, in theory, causing permanent damage. However, the day of the test was cold and rainy. The water droplets in the air did what moisture always does: they absorbed the microwaves. And when some of the reporters volunteered to expose themselves to the attenuated beam, they found that on such a raw day, the warmth was very pleasant. The story is much the same in other areas of HPM weapons development, which began as an East–West technology race nearly 50 years ago. In the United States, where spending on electromagnetic weapons is down from cold-war levels, but remains at some US$47 million per year, progress is elusive. 'There's lots of smoke and mirrors,' says Peter Zimmerman, an emeritus nuclear physicist at King's College London and former chief scientist of the US Arms Control and Disarmament Agency in Washington DC. Although future research may yield scientific progress, he adds, 'I cannot see they will build a useful, deployable weapon.'"

The anti-terror guys have warned us for years that a microwave cannon could be built with parts ordered from the web, capable of frying a plane's electronics when it tries to land.

So I guess Mythbusters didn't get an authorization to test that either.

A water cannon would have done a better job than the microwave weapon anyway.
Especially in desert countries with primitive plumbing and sewer systems.
The people you linked to were not protesters, they were rioters and anything but peaceful.
So you wouldn't object to using it on them then?
It makes it way too easy to disperse peaceful protestors when their message is politically inconvenient.
They can already be dispersed with ultrasonics or chemicals which would leave no photos and limited trace. If the government is going to cross the line to coercion it is going to cross the line. The problem isn't the nature of the weapon so much as the nature of the government. Totalitarian countries are totalitarian due to the behavior of the government, not because of the weapons they have.

No new weapons? What a tragedy.
I prefer living in a country that wastes money trying to find non-lethal weapons that don't work out vs. countries that take the cost-effective, pragmatic approach of "f**k em, bullets are nice and cheap."
There are plenty of reasons to criticize the US Department of Defense, no question. But the fact that they are spending money on non-lethal weapons means they at least care about a future war where not everyone has to get killed. Or even if you want to indulge your most Reynolds-wrapped tinfoil-clad conspiracy theories, a future where US domestic political protestors don't meet the same fate as those in the Prague Spring, Tienanmen Square or Syria.

When you design a weapon that is inferior in every way except that it's use leaves no obvious traces, it has only bad uses.
That applies to ultrasonics as well.
You mean like a Taser? No cops EVER misuse those...
