How Hot Would a Light Saber Really Be? 410

Posted by Cliff

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."

    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.

        These things don't exists
        True, and the headline shows an ignorance of basic chemistry. Any oxy-acetylene cutter doesn't have to be hot enough to melt steel - the steel oxidises and burns away - so some sort of device that ionises air would be hitting steel with a lot of hot oxygen and burning it away. An oxy torch that cuts through steel like butter has trouble getting through aluminium alloy despite it having a melting point around 1000k less.

        Plasma cutters are something else again, real and possibly far more like a light saber would be if such a thing was real. Heating up a gas and making it behave a lot like a liquid to burn things away leaving nothing but a clean cut and hot dust is the way the things work - all you need is high voltage electricity, appropriate electodes and a good supply of pressurised gas.

          Scott Adams wrote a book, God's Debris [andrewsmcmeel.com], that explores your question of what happens if God gives up his omnipotence. I'll let you read the free ebook yourself, but the basic idea is that God, as a perfect being, gets bored of his own existance and tries to spice things up by committing suicide. In doing so, God created the universe.

          Wikipedia notes the parallels of this to Hinduism. When I read God's Debris, I was reminded of GWF Hegel's Philosophy of Religion, where God also empties himself of divinity in order to start time and create the universe because he realized that his pure existence is meaningless. Time is the progress of God, the spirit of whom is now extended in all matter, coming to 'realize' himself as God. So, in a sense, God is evolving.

          These theological moves (God is extended in the world and God is realized in the future) allow for dodging some thorny questions. For example, Can God create a rock that he can't lift? The answer is, for *now*, yes. But he might be stronger tomorrow.

    The light saber would need to be 6241 F to cut through metal. At that temperature, the metal would be separated into sub-atomic particles called 'fooltrons'. As I'm sure you are aware, fooltrons are far to small to cause damage to the human body.

    could you toast marshmallows with a light sabre. On the one hand, there's plenty of energy, on the other hand the energy doesn't seem to go very far from the blade. I'm sure if you just touch the blade to the marshmallow it'll just vaporize though. Perhaps a wise Jedi, skilled in the force, could do this. Or maybe force lightnight. I guess you could heat a rock with a sabre and then toast with that, but it's just not the same.

      Well, assume for a moment that it works. To melt metal one needs a lot of energy - so it likely comes from a nuclear source.

      1kg of steel has specific heat of 448 joules per degree Kelvin.

      Energy from fusion of hydrogen atoms is at most 8 Mev, the energy stored in Hafnium atom is 3 Mev - let's assume that the agent used has weight of Hafnium but produces 1 Mev per atom.

      Thus 1kg of energy agent stores 9e10 Joules - plenty enough to heat 20e3 tonnes of steel to 10000 degrees - cool !

      So, as long as I am having fun, here is a "complete" light saber design - just so that no one tries to patent something that obvious:

      • Handle - let's separate in two compartments - one contains energy agent and the other initiator that bombards that agent with nuclear particles.
      • In response to bombardment energy agent produces new particles in much greater proportion - this is a sticky point as single pass stimulated emission amplification is likely not that efficient - but then we have power to spare ! In fact this might be a feature as the handle will last very long time - the amplification medium will deplete slowly and from one end.
      • the particles are passed through moderator which limits their mean path in air to desired length.
      • put peltier element around the energy agent and moderator and feed the energy into the initiator.
      • initiator could be made as short pulse laser striking metal foil - these have been tested as tabletop devices already and should be capable to produce 3Mev gamma rays.
      • move the initiator around as energy agent is used up.
      The particle fountain would be very narrow - but it will heat up the air and that would produce the glow. Oh - and plasmas are opaque to light so there will be a shadow.

    It's an issue of temperature AND power.

    Consider this: how hot does something have to be to melt an ice sculpture? Well, a match would do it, except a match can't provide the power necessary to melt a significant amount of ice.

    You need the temperature necessary to turn steel into a vapor (look that up on a periodic table of elements); you also need the power necessary to turn some mass (per second) of steel into vapor. Anyone with a background in chemistry should be able to look up the required information on a standard periodic table.

    The equation will look like this:

    (Steel's specific heat) * (volume of steel to vaporize per second) * (temperature difference) = power necessary.

As for the heat...a portable (55 amp) plasma cutter can cut 1/4" material at roughly 70 inches per minute. The plasma coming out is roughly 24,000 degrees, and is a stream traveling at 20,000 fpm.

    However, it's not a simple plasma. It would have to be a high energy density plasma, in order to look solid and act solid.


    The example I found of a Tocamac plasma [pppl.gov] is only red, but is 20-30 million degrees C. However, the lightsabers in the original (and therefore One True) Star Wars were white. This means they must be considerably hotter. The page I found on near-solid high energy density plasmas [utoronto.ca] also talks about tens of millions of degrees - my gut feeling would be that to produce totally solid white plasma would require 40-50 million degrees C.


    Now, plasmas at that kind of temperature could quite reasonably be expected to slice through almost anything - steel included. Furthermore, anything that was vaporised would be repelled by the magnetic field and thus travel AWAY from the wielder. This does mean that if you are fighting someone with a lightsaber, you will get sprayed with high-energy plasma every time they hit something.


    There is one minor problem, though. Energy. If you want to maintain something at 50 million degrees, AND a containment field, a couple of duracel batteries won't cut it. Even lithium batteries will go flat very quickly. My guess is that the handle of the lightsaber, therefore, contains a wormhole linked to a gigantic anti-matter reactor.


    All you REALLY need to do, then, is find out where your opponent's reactor is hidden and turn it off. Their lightsaber will then be useless.

    • A plasma doesn't behave like a black body, so the blade would not become "whiter" as the plasma got hotter. The plasma of choice would have a couple of visible spectral lines (depending on the gas you ionize), and making the plasma "hotter" would just make those specific colors brighter. You can doubly ionize and even triply ionize the gas, but these transitions typically fall out of the visible range.

      Also, the magnetic field by itself would just constrain the particles to the axis of the saber. There's

    • I don't think the light is part of the process at all. It's a red, green, or blue (or sometimes purple) herring. The light is probably added by whatever OSHA dealy they had a long time ago to show where the dangerous part is...

      But the real question is: where did lucas get a telescope powerful enough to record all of this?

    OMG SOOOOOOOO HOT!!!
  • The specific heat of steel [wwu.edu] is 452 joules per kilogram per degree C.

    The melting temperature of steel [jlab.org] is 1370 degrees C (room temperature is 20 degrees), so the the lightsaber has to raise the temperature 1370-20=1350 degrees C).

    Now (to pull some numbers out of my ass) let's say our hypothetical jedi swings a 1-meter-long-and-.02-meter-wide lightsaber through a bulkhead in a circular fashion, sweeping out a 120 degree arc. The volume of steel he has to melt is (120/360) * (pi*r^2) *width, where r = 1 meter an

    Don't use your light saber to open beer bottles
    Don't use your light saber to pick your teeth.
    Don't use your light saber to gut fish

    If you do any of these things, you might be a jedi redneck.

  • Light sabers are pretty advanced pieces of technology. Let me try to explain how they work in basic terms.

    First off, you need to imagine a sort of 'shield' around the blade. It is this shield that actually forms the blade in to a specific shape and length. It uses micro-miniature deflector technology. It's all deflector technology these days. If you can picture a sort of transparent hollow tube you are on the right track. In fact, if a Jedi needs a non-lethal billy club he/she can simply switch off the fusi

    Normally, my interest in applying practicle science to the star wars universe would be astronomical, but reading the question in pink GUI made me realize what a nerd loser I was. Thanks a lot slashdot. :-(
