Emergency medical care for soldiers wounded on the battlefield has come a long way since Hawkeye and Hot Lips. But for Special Forces troopers operating deep behind enemy lines, that care often remains out of reach. Blood loss in particular makes seconds count, and imperils commandos operating far away from friendly bases.
To help with the problem of blood loss from traumatic wounds, the military has started field-testing a device more Mandalorian than M.A.S.H.: a plasma knife.
The knife, whose blade consists of heated, ionized gas, cuts through flesh just as easily a steel scalpel, but also cauterizes the wound. By sealing off the damaged flesh, the plasma knife protects against infection, and stops the bleeding that imperils the wounded soldier. Think the crispy stump of Luke's severed hand, and you'll get the picture.For now, the plasma blade remains a life-saving device, not a weapon. But I think it goes without saying that we all look forward to the day when the military converts this technology into a more elegant weapon, for a more civilized time.

Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.

I want one.
dido, forget ever having to sharpen a knife again.
Can it cut your braid and toast it at the same time?
Yes, anime master, it would. You would need to cut very quickly, however, to avoid burning bread (the moisture in bread being much lower than flesh).
Of course, using this thing on a person would cause ridiculous amounts of pain. While the heat would be very intense and kill nerves nearby, the heat from cauterization would spread back into the flesh. So, jack someone up on morphine BEFORE using this thing on flesh.
Also, plasma arcs tend to spread (like the light of a flashlight). A short scaple blade would be far easier than a sword (and much more useful). Plasma also need lots of energy to start, and plenty of fuel. So, forget your lightsaber anytime soon. A plama arc flamethrower, however, is a rather easy DIY home project with simple welding gear.
I see this as another body-modification 'option'.
OMGZ! I want this! lol
Yes, young padawan, you shall get one soon enough. one of the tricks you must learn to be a jedi master, patience, you must have. Yyyeeeeeeeeeeesssssss. Soon you shall have it, yessssssss. out of jedi mode. hey, could they put this thing on, say, a stump of a hand, like a hook-hand? and do they work with, like, a button? if so i want one. and also, oakspar77777, shut up, you are ruining our hopes and dreams.
p.s. these things are SWEEEEEEEEETTT!!!!!!!!!!!
p.p.s. mel brooks ownage. ^_^
p.p.p.s. oakspar, the thing would be burnt, killing the nerves, so yes, it would hurt, but you would probably pass out within 10 seconds.
p.p.p.p.s. too many p's.
a more "elegant" wepeon -_- mhm yes were going away from our GUNS and ATOMIC bombs and were going to start using swords again on the battlefield.
so would it be possible to turn this into like a plasma arrow?
get a plasma knife, turn it on, add some feathers, string it to a crossbow, and fire. :)
we can work on the bullet later.
As well as cutting bread and toasting it, can I use it to heat my coffee as well?
.....Wait, is plasma water proof? :P
I would only see that as a practical use if you enjoy coffee vapor. Heck, maybe if you put the vapor inside a glass, and you made the conditions right, you could make it rain coffee!
Ah a new Assassin Weapon. Neat and the cut cannot be matched to a metal blade by CSI. Kind of like the few murders made by an icicle blade later left to melt thus making the weapon of choice magically disappear. No doubt the military forces of the world would embrace this new technology for what it might perceive as a new weapon to use on the battlefield. Star Wars as well as Star Trek foretold of such weapons and now that prophecy has prov-en to be true. But still unbelievable....
you know if you think about it .. if you take a holder with lots of space and instead of using plastic like those plastic kid light sabers .. use metal. making it collapsible just like the ones they sell for kids. start the ark from the hilt and then make it flow to the top .. hence a "light saber" .. it wont totally disappear like a "light Saber" that just makes the energy go away but it will make do and do almost the same thing as normal light sabers (in movies)except go through concrete and whatnot :D ..
Hey tell me when you dicover that we can use the force now that would be a cool combo to have. Plasma Knife(lightsaber)and the force.
I realy want one of those but in a sowrd!!!!!! coool!!! People can fight like a jedi or a sith like in the movies. Amazing what the military can do.
You picked spaceballs for the pic for this article? LOL
imangen this armor will no longer be a problem for special opps
zomg. can we make blaster bolts now? how bout droids? star estroyers? clones? tell me!!!!!!! and actually, it is possible to use the force through genetic "mutations" done by futuristic sciences that increase the bodies power and telekinetic powers, so... i want that.
I bet it makes sliced lunch meat delicious! Hard salami and corned beef here I come!
I know how!
:) Hey peoples, if that blade is from "ionized gas", that is not a "Light-saber"!!!
It's not have posibility to stop another one...
...Think litle, please!
To heal without blood yes, to kill without blood yes, but for long range weapon will be lost of a expensive equipment...
...But why not peoples make everything to kill another human!!!
lol this inventions so cool it could also be used a building tool and can possibly be used to cut through diamond eventually
