A US company claims it is ready to build a microwave ray gun able to beam sounds directly into people’s heads.
The device – dubbed MEDUSA (Mob Excess Deterrent Using Silent Audio) – exploits the microwave audio effect, in which short microwave pulses rapidly heat tissue, causing a shockwave inside the skull that can be detected by the ears. A series of pulses can be transmitted to produce recognisable sounds.
The device is aimed for military or crowd-control applications, but may have other uses.
Lev Sadovnik of the Sierra Nevada Corporation in the US is working on the system, having started work on a US navy research contract. The navy’s report states that the effect was shown to be effective.
MEDUSA involves a microwave auditory effect “loud” enough to cause discomfort or even incapacitation. Sadovnik says that normal audio safety limits do not apply since the sound does not enter through the eardrums.
“The repel effect is a combination of loudness and the irritation factor,” he says. “You can’t block it out.”
Sadovnik says the device will work thanks to a new reconfigurable antenna developed by colleague Vladimir Manasson. It steers the beam electronically, making it possible to flip from a broad to a narrow beam, or aim at multiple targets simultaneously.
Sadovnik says the technology could have non-military applications. Birds seem to be highly sensitive to microwave audio, he says, so it might be used to scare away unwanted flocks.
Sadovnik has also experimented with transmitting microwave audio to people with outer ear problems that impair their normal hearing.
James Lin of the Electrical and Computer Engineering Department at the University of Illinois in Chicago says that MEDUSA is feasible in principle.
He has carried out his own work on the technique, and was even approached by the music industry about using microwave audio to enhance sound systems, he told New Scientist.
“But is it going to be possible at the power levels necessary?” he asks. Previous microwave audio tests involved very “quiet” sounds that were hard to hear, a high-power system would mean much more powerful – and potentially hazardous – shockwaves.
“I would worry about what other health effects it is having,” says Lin. “You might see neural damage.”
Sierra Nevada says that a demonstration version could be built in a year, with a transportable system following within 18 months. They are currently seeking funding for the work from the US Department of Defence.

The Department of Homeland Security sponsored a study on the threat of abnormally large Coronal Mass Ejections on our power grid. They estimated that for only $100 million dollars, our power should be protected from severe geomagnetic storms.
Kapppenman (2010) Worst-Case Scenario for Grid Damage by Geomagnetic Storms
A report prepared for Oak Ridge National Laboratory by John Kappenman an independent consultant, examines the vulnerability of the U.S. electric grid to severe solar storms. The report has generated great interest in government and the public, largely owing to the projected scenario of catastrophic damage, including:
- More than 300 EHV transformers destroyed
- 130 million people lacking power for several years until damaged high-voltage transformers are replaced
- 1-2 trillion dollars of economic loss.
Yesterday’s X5 Flare released a coronal mass ejection (CME) that hit Earth on March 8th around 1100 UT, with little effect. Nonetheless, every time there’s an X flare, people go apeshit and start searching Google for solar doom links. Here’s my toss in the pool. The sun’s been on my mind lately, prompting this cautionary tale of magnetic mayhem.

Have you heard about the Carrington Event? It was the largest CME ever recorded, dwarfing the puny little flare you just saw in the video above.
May 6, 2008: At 11:18 AM on the cloudless morning of Thursday, September 1, 1859, 33-year-old Richard Carrington—widely acknowledged to be one of England’s foremost solar astronomers—was in his well-appointed private observatory. Just as usual on every sunny day, his telescope was projecting an 11-inch-wide image of the sun on a screen, and Carrington skillfully drew the sunspots he saw.
On that morning, he was capturing the likeness of an enormous group of sunspots. Suddenly, before his eyes, two brilliant beads of blinding white light appeared over the sunspots, intensified rapidly, and became kidney-shaped. Realizing that he was witnessing something unprecedented and “being somewhat flurried by the surprise,” Carrington later wrote, “I hastily ran to call someone to witness the exhibition with me. On returning within 60 seconds, I was mortified to find that it was already much changed and enfeebled.” He and his witness watched the white spots contract to mere pinpoints and disappear.
It was 11:23 AM. Only five minutes had passed.

In case you didn’t know, bullets, bombs, and nuclear weapons are old school. War mongers were far more interested in the electromagnetic pulse (EMP) “side-effect” of nuclear blasts than the explosion itself. They sought to harness these energies, in new pain-generating ways, to subjugate and demoralize all opposition. This page will contain extensive information on the history, current use, and future of directed energy weapons.
