The Riddle of Steel Freedom Steel International

Cutting through solid steel with flaming bacon certainly has its appeal, but for large-scale industrial processes, the Fraunhofer institute thinks electromagnetic pulses may work better than the other white heat. Case in point: their new electromagnetic pulse (EMP) device that cuts through steel faster than a laser, and cheaper than a machine tool.

The device uses a mixture of capacitors and coils to create a directed magnetic field that works like a paper-hole puncher. The shaped magnetic field pounds steel with 50,763 pounds per square inch, or three times the pressure at the bottom of the Marianas Trench. At that power, the blast can punch a hole through steel seven times faster than the lasers currently used to do the same job.

To protect passengers in case of a collision, most car manufacturers craft the car body out of some of the toughest steel available. Unfortunately, the same toughness that makes the car so safe also makes the body very difficult to alter during construction. To create holes for wiring, car companies use either mechanical tools, which wear out and add an additional step to remove the subsequent burr, or lasers, which require a lot of energy and money. The Fraunhofer EMP device doesn't have any of those drawbacks, while retaining most of the advantages.

Additionally, the process leaves no burr or hanging metal, eliminating expensive finishing steps in the assembly process. And with no moving parts, the machine experiences far less wear than mechanical tools.

The EMP device isn't widely available yet, as the company perfects how to manufacture coils in a wide range of different shapes. But if anyone needs to punch a hole into some tough steel, I think you might want to give Germany a ring.

That is astonishing, the emp devie that can slice through steel at such a rate is astonishing. The applications to other things would be incredibly endless, one idea may be compacting that technology to rifle sized weapons! Thes could be used for those knarly wrecks on the interstates, or train crashes. Mabye for moblie contrustion. Allowing that capiblity is going to be a very versitile thing. Mabye if we could find a power source that could sustain that machine it just may be the next generation weapon. *(hence starwars, or fallout3)* This inovation could be apllied to battleships, aircraft, and soon is possible starships. This is truely a step forward.

Wow, reading all that it really doesn't give much of any information. Thanks popsci...

hey lets put this stuff on a sniper rifle and send it to iraqi bye bye terrorists and tanks

Yes that is astonishing we can impliment this to help others around the world. We should not use this for war. Only to benifit mankind.

Now someone needs to make a DIY tutorial for making one of these at home.

this will easily find its way onto the battlefield, as war is mans most natural state and its pinnicle of technology. I am willing to bet that DARPA is already working on it. Ultimatly war benefits mankind.

Seems to me that this EMP is only useful at close range where the Pulse is more focused at a specific point like an industrial laser, or else it whould go true the metal and what ever is behind it.

And the energy disepates as it moves foward,so making it a weapon that can go true solid structures at very far distanses would depend on it's wave length or frecuency, simular to micro wave energy, that disipates with distance, it would be more usefull at shuting down electrical systems.

And to make it more powerfull would mean a bigger unit that needs more energy, adding more wait and hindering mobility, especialy for a hand held portable unit.

And i would rather it stayed in the cuting buisness and not in the military onless to short out circuts or so! as a non leathal deterant against there anemys.

if they do end up making this and integrating it into weapons, we need to keep it exclusive and find a way to break down our weapons, like have something that just completely destroys the gun. if any of you have played crysis you might know kind of what i mean. they had to vaporize that one guy in the nano suit who died to keep the technology away from the koreans

this technology has no direct (sending a magnetic wave to cut through something) application in projectile weaponry - as magnetism diminishes exponentially over a distance. But it is similar to the rail guns we've been hearing about, the ones they ARE putting on the next gen US Navy ships, which use magnetic coils to accelerate a projectile to hypersonic speeds, relying on the projectiles kinetic energy upon impact (which would be a lot at those speeds, so much so, that it actually explodes) to do the damage. this same concept has also been suggested (and used in scale tests) as a way to launch payloads into space (obviously not living ones, as the forces and acceleration involved would most likely liquefy anything living).
long story short - magnets no good at range, but can be made so that they can throw things really far, really fast. or punch through solid objects like Chuck Norris.

side note: the only other weapons purpose for EMPs that we currently have is as a way to knock out unshielded electronics and wipe data storage devices. A single modern nuclear warhead detonated at the edge of space can spread a pulse over the entirety of North America and destroy what ever electronics (electricity and Data) networks that are not shielded.

It could be used like a shaped charge. Put it in a container then glue it to a wall and then you have a nice clean hole. Ot in a RPG. When the rockit strikes a tank it activates the EMP and it cuts through the tank's hull. Or a tank mine or anti personel mine.

you would have to be carful though. If your own equipment is near the blast it could knock out your electronics.

This is old school tech, just now being realized by the general public. In general laymans terms, it's called an "induction coil" in the field of electronics. In other words, just an "thick" coil with a bank of capacitors and a power source to power it. Put any metal in the center of the coil and it will melt the metal in seconds. As far as controlling it as a dicharged projectile, well, use your imagination and magnetics or electro-magnetics. There are somethings in the world your not told about, like replaceing the electro-magnetic coil in a cars alternator with a permenate magnet to get free DC electrical energy. Remove the diode from inside the alternator if you want free AC electrical power. Incert transformers to step up or down the power and so on and so forth. One can also use home grown crystals to channel lens focused sun light onto a solar panel to increase the panels output without frying the panel, and also to heat material like an open microwave too. Do your studies. You'll be amazed at what you can learn to do at home.

P.S. What I mean by "Thick" coil. The wire gage needs to be a thick gage. The thicker the wire that the coil is made of, the more power you can put through it without the wire melting. If you realy know your stuff on electronics/electricity then you can tune the frequncy to improve it's performance to make it more powerfull. Also on the free energy alternator, make sure the axel ring magnets polarity is pointing the correct direction. You can check this with a compass and compare it to the coil after coil removal and bench testing the coil to see which pole was facing the front of the alternator.

Look up microwave cannons and vortex cannons on you tube. Thats intresting too.

why couldn't the electromagnetism be focused into a laser like light? light is electromagnetism.
If this was used as a weapon, it could be as strong as a nuclear bomb, and as precise as a laser.

I don't wan't this to be turned into a weapon; it would be attached to a predator U AV and the military would have unstoppable power.

Is the 50,763 psi number correct, because the average ultimate tensile failure strength for steel is 60,000 psi (depending on heat treating and composition).

It doesn't even tell you how big the thing is. Doesn't tell you how much energy it takes. The article doesn't tell you much about it at all except that it can make holes. Why do you people assume that something that can make holes with an EMP can be used to shoot stuff?

weponizing it could prove difficult because of the rate of dissapation of the magnetic energy over distance, right now useing it to shut down tech is enough for me

Reminds me of disintegrator gun from Dark Void which you can use against the Watchers, who were like advanced robots, and blow them to pieces at close range. Look it up.

"Ultimatly war benefits mankind."

You been to a war lately? Messy business. Doesn't provide much benefit to the individuals it destroys.

See your recruiter. Go benefit mankind. When you get back, come to my VFW Post for a beer.

@thor0997
i like your rpg idea. the trigger for the emp would obviously have to be embedded in the nose spike. i suppose it would also depend on long it takes this device to turn on (and warm up, if needed). maybe a calibrated delay like in those new "smart shells" the army is experimenting with.

Hmm EMP's to shut down grids. Now they can cut through steel there goes the US fallout bunker that is "protected" against EMP

Think people..... this will not work it's way onto the battlefield, this worked it's way from the battlefield to an industrial application. All technology that 'we' see with rare exception is decades old.. Where do you think most of the taxpayer money (about 67% of it) has been going?

Since the end of WWII, Nazi technological development has continued in the US, Argentina, Egypt, China and likely a few other places including anti-gravitational tech. Are you aware that a moratorium was placed on all world universities disallowing anti-grav research and development since the 1950's?

They show us these weapons all the time! They blasted Hulk with plasma guns and Schwarteneggar used EM pulse weapons at the docks with Vanessa Williams about 15 years ago to name but two examples... These weapons are frequency attuned as well so that they will impact only that which is harmonically compatible with the pulse energy! Doesn't take too much grey matter to realize that biological material can be targeted this way too...

Cutting through steel... How else did 9/11 include ravaged cars within a one mile radius of the WTC Building though the upholstery and plastic was completely unaffected? Why wasn't there a tsunami in Haiti nor lateral shaking only intense vibration? DO the research. most of it is on the internet or maybe, just maybe read a book! Check out Nick Begich and his HAARP research to get you started...
