    I dunno...what would be the point? They're useful in SW mainly due to the fact that the people using them are psychic monks, and because of how blasters work -- relatively short range, inaccurate, and deflect-able.

    This reminds me of an xkcd comic.

    The ceramic rod invalidates it as a lightsaber. A lightsaber's blade is made of pure energy. So the electromagnetically contained plasma torch is more of a lightsaber than the final design even if it just passes through the other blade.

    Well, in SW canon, the ceramic rod from Kaku's design (I'm assuming this is his doing you're talking about) is replaced with a forcefield. In other words, if you could keep the hilt from melting down, you could probably make a perfectly functioning lightsaber in Star Trek. You have superheated plasma, you have forcefields... :P

    I've always thought that a lightsaber's blade should be a very tightly focussed forcefield. It's the only thing (IMHO) which explains the blade's various properties...

    Lol, good responses from everybody and, love the aussie saber idea.

    Remember, it is only a theoretical idea and, probably not how the movies actually depicted physics.

    After all, we are nowhere as advanced as the films, when it comes to technology.

    I wouldn't mind if the ceramic rod wasn't there at all. Just having the self contained plasma would be more than enough for me, however wouldn't it be possible to change the polarization of two of the different magnetic fields so they would repel eachother? If you could then that would mean that you theoretically could have a sword fight with them. The only downside would be if you engaged an opponent that had the same magnetic field polarity...

    Yes that would certainly be a problem.

    Some people suggested a type of energy field, which would kind of make sense if, it were inside the plasma blade.

    The forcefield would be the containment for the super excited plasma within. The powersource and cooling system is obviously the problem.

    A forcefield would not require the presence of plasma at all, thus negating the need for a cooling system...

    When a lightsaber has demonstrated 'heating effects', such as when Qui-Gon tried to cut through the blast doors, this can be just as easily explained in the same manner in which the friction of a file against metal will cause both to heat up, despite both being cold to start with, (and that 'friction' would come from the movement of the particles which create the forcefield) A forcefield would also explain a lightsaber's characteristic hum... :cool:

    I think it's demonstrated heating effects beyond what mere friction could achieve in this instance. Besides, since when do forcefields glow?

    Really? I would imagine the particle movement within a forcefield to be 'quite energetic'...

    :confused:
    Quite often, especially upon activation...
    Tractor beams are always visible, and I believe forcefields are a different utilization of the same technology...

    Consider a kind of modified (and highly focused) tractor beam, and I think you would have something which would have the same properties of a lightsaber :cool:
