How Hot Would a Light Saber Really Be?

Datagod asks: "Has anyone ever calculated the temperature you would need to be able to slice through steel like it was thin air? How hot would a light saber really need to be? Also, I am assuming that at least some of the metal would be vaporized and the expanding gas would fling bits of molten metal at the saber wielder. Wouldn't your average Jedi be horribly scarred from all this."

      My Firefox browser was hijacked, endless screens opened up and somebody's voice came over the speaker saying I know not what. One of the screens was an unpleasant image.
      OK, I've been April Fooled. But I doubt it was the sort of thing slash.dot approves of and if it does, I'm disapointed.

    A nanotech style light saber would be the best way to go. Nanites could burn through their target and work on a whitelist principle: a friend's DNA would be ignored.

    Quite literally you could ram your nanotech light saber through a hostage taker and the nanites would decline to harm the whitelisted hostage.

    I can't believe no one else thought of this. PATENT!!!!!! OMFG I am teh pwnz0r take that George Lucas!!!!!!

  3. Light sabers are not hot by tuxlove · · Score: 5, Insightful

    Light sabers work at the subatomic level, disintegrating matter. However, heat is generated within resistant materials, giving the impression that the sabers themselves are actually hot. Don't the slashdot guys know this?

    "Wouldn't your average Jedi be horribly scarred from all this."

    Not necessarily, Padawan. If a Jedi cuts through a door/bulkhead/vehicle with a light saber s/he could avoid getting splashed with melted metal by applying a subtle Force push along with the slicing motion of the saber. To Saber 101 class you should return, youngling. ;)

      It's all good, today is not a good day to have mod points anyways, I guess.

      Seeing how the grand-parent got modded, I conclude that I hardly understand any logic in the modders mind anyways. Instead of considering using quasars for encryption, they should rather consider using /. mods.

    It is a time of great eye protection in the republic.

    Eyeprotection worn by leading scientists without the force powers to deflect metal bits from their eyes.

    They found the lightsaber:
    Was developed from an ancient bread-slicer / toaster.
    Contains 1.21 gigawats of power between recharge of it's flux capacitors.
    Ranges from 350F to 50000F (battery life may suffer from extended operation, and overheating may occur at high temperatures.
    Still makes a tasty grilled cheese sandwich in a pinch.
    It was a dark time in the Republic.
    Mainly because light sabers are really, really bright at high temperatures.
    So bright as to be blinding.
    Hence the recall. ........

    "Could Jesus microwave a burrito so hot that he himself could not eat it?"
    No, he could always eat the burrito, no matter how hot. He would just suffer while eating it. Horribly. For all our sakes. (And of course, since a Jewish man prepared the burrito, we Christians would hold the Jewish people guilty of this for the rest of time, or at least for a millenium or two...)
