A real-life lightsaber? Military device cuts through metal

By | December 7, 2012, 4:40 AM PST

Whether you’re Star Wars fan or not, brace yourself. A little-known defense technology firm has developed what’s been called the closest thing to a real-life light saber.

Resembling a sturdy metallic flashlight, the Metal Vapor Torch certainly looks the part. With the press of a button, the wielder can ignite a fiery blade powerful enough to slice through solid metal. Energetic Materials & Products is marketing the tool as ideal for pulverizing deadbolts, padlocks, chains and just about any deterrent you can think of. It may be particularly useful for military personnel, police and emergency responders since they’re often called to situations in which agents may need to breach a secured site within a matter of seconds.

As Popular Mechanics explains, the torch generates a momentary jet of flame using a complex mechanism that involves copper oxide, magnesium and aluminum particles. The resulting concentrated stream of heat shoots out at a blast speed of over 1,600 miles a second with a temperature above 2,700 degrees Celsius. And as it exits out the rectangular-shaped nozzle, it comes out in the form of a sharp blade.

But sci-fi fans should take note that any comparisons to lightsabers are somewhat of an exaggeration since the technology is, at best, more akin to a burning pocket knife than the laser-powered plasma variety designed to combat evil empires. As you can see from the video, the torch’s effect lasts only a few seconds as it relies on disposable fuel cartridges. Still, scaling up the technology, the company says, would enable troops and law enforcement to tear through inch-thick steel and fiberglass.

The Metal Vapor Torch is expected to sell for 135 dollars a unit, with cartridges costing around 35 dollars. A version of the device for testing will be available for defense and police agencies later this year.

It's not a light saber doofus...
It's just a small portable thermite torch.

Regardless of title.....
It is a relatively inexpensive expedient to get people through locked and hardened places quickly and with very little fuss. Although as the video shows, there is quite a bit of "Muss" In a government budgetary nightmare of $500 toilet seats and such, a $135 tool with $35 fuel cartridges is truly bargain basement merchandise.

I can see an EMS worker...
I can see an EMS worker accidentally burning down a building trying to get into one apartment. Also, did you see how that big guy had to brace himself against it? For $135 plus $35 for the cartridge, you could have 3 or 4 large bolt cutters to do the same job without the hazard. With a guy that big behind it, the bolt cutters may have been even faster.

I give it an A for effort, but a D for practicality.

criminals will have them
Criminals will now use these to breal in. But, the materials in the gas seem conductive, so, when that much heat is detected, discharge a 47uF 12KV capacitor through the offending plasma stream. Problem solved.

not so cool
I can see the police burning down a house that is the wrong address, happy joy for the poor Schmuck that live in poor neighborhoods. Should be fun to watch and hear the apologist come up with excuses.

Think twice, cut once.
Reminds me of the story told by a friend. While he was working, a fire call went out for his house. When it was all over, he went to thank the fire chief. He said: You guys did great, but I wish you wouldn't have broken the door down. IT WASN'T LOCKED!

Too expensive as a boltcutter.
My boltcutter (70 years old, made in Boston of drop forged steel) is certainly more effective than this metal oxide torch. It will cut through either of the demonstration pieces faster, requires no cartridge, has no fire risk, and can be reused many times. Impressive chemistry, but misplaced application. Use it for something else e.g. a solid rocket booster fuel. The 1600 miles per second speed is 2% of the speed of light. We have no rockets capable of that kind of thrust. A rocket operating at that speed could put something in orbit in a second or shoot down an enemy missile almost in line of sight with minimal guidance. Imagine the possibilities.

Just the beginning
I agree, right now this tool is pretty useless. There are bolt cutters and saws that can do the same thing for cheaper, with less hazardous materials, but you have to think that this could just be the beginning. When the computer was first invented it was the size of a gymnasium and pretty much did the same thing a slide ruler did at the time. Now look at where the computer has come. 50 years from now we may have actual light sabers that have evolved from this tool.
