Okay i got one question would the material he uses to build the blade itself, actually be able to withstand the force that the two swords will be smashed together with (if you watch the Star Wars movies its quite clear that the jedi aren,´t taking it easy when it comes to hitting the two swords together) or would it be smashed after the first two or three hits?

And since we,´re in the realm of Sci-fi i,´ed like to take up an entirely different subject the science of Warhammer 40k namely the Eldar and their way of building things.
In the 40k universe they use a substance called wraithbone which is a warp material (of some kind or another) and Eldar who specialized in forming it use instruments of sorts to shape the bone till it uptain the form they want it to.

My question is would that be feasible in the real world? Could actually make a substance that through electrical or sonic impulses could be forced to grow into the structure we want it to be or would it end up being to inconvenient compared to doing things in the traditional way.

Another fun fact though we have invented exoskeletons our main problem with them is that in their current form, they take too much energy for any battery we know of to power them for any longer then a minute top most.
Maybe if those nanotubes he uses to power his lightsaber really could hold such a large proportion of energy they might be formed into the battery we need to power suchg an exoskeleton for a longer period of time.

Having seen documentaries on the making of the Star Wars films, I can guarantee you that they will bend.

Would it break? Yes! Even tough ceramics can be harder than most metals, they really suck at absorving impacts.
Plus that was a crapy coup out of a lightsaber, they should have rather say a lightsaber look alike. Plus having a force feedback isn't the kind of thing you want in a weapon, if you can just cut the other guy right of without giving them a chance to defend himself what would you chose?
Exoskeletons are cool, I don't know why you need the power tough, but I guess you mean exoskeletons that do the walking for you.

There would be several usages for a fully powered exoskeleton, both in military and civil sector.

Take several of the jobs today that actually requires heavy lifting like hospitals and such (patients aren,´t exactly lightweight all the time) and often you need the assistance of several people to ensure a stable lift.

With and exoskeleton or power armor of you like that term, that will mainly assist in the lifting and such a 110 kilo heavy person might fell like an infant weighing just a few kilos and a stable lift could be done with two people a the top most.

In military well the different sci-fi games have already shown plenty of potential a fully powered exoskeleton might be able to do.

Like this: http://en.wikipedia.org/wiki/Molecular_nanotechnology?

We're not building tanks and such with it yet, it's all nanoscale structures. This looks pretty neat though, if far-fetched http://en.wikipedia.org/wiki/Utility_fog.

I am wondering how the solenoid will be protected against the high temperature of the torch?

Yeah, ... you should not point it to someone's eyes.

Let us assume for a moment, that the sabers wielded by the almighty Jedi Masters wouldn't vaporize them from simply the heat.
The only solution in this problem is the physicist solution for EVERYTHING when there is not enough energy available to us in such a compact manner...
Hurr durr anti-matter durp

And that doesn't address the rest of the problems with a light saber. That is only one.
The only thing that they seemed to have hinted at getting correct are the knobs on the handle for adjusting Arc and frequency of the emission, which would effectively control the blade's size and the power contained within the saber. (Even then, theoretically I could slice through another blade by adjusting mine down, so that the arc is smaller and that the frequency of the relays of the emission are greater than that of the other...
Higher frequency = More energy = Fuck you)

If it was argued that the light saber was powered by the Force, and that the force protected the wielder, then it would work very simply - but that's not scientific, is it?

can't argue that, han solo had no trouble using luke's saber in episode 5.

Are we sure we want to go down this road?

I assumed that light sabers used the same force field technology that you see all over star wars that allows ships to pass through them but not atmosphere. Remember the scene where the millennium falcon is being tractored into the deathstar hanger? There's dudes running around inside as it's passing through the shield, so either they can breath in space or there's some force field keeping the air inside. Don't see why the same force fields couldn't act as a containment field for the high energy plasma in the light saber.

Now, why would the force field only repel and contain the plasma and not just, well, everything you ask. Why silly, obviously it's the shield frequency. Your lightsaber plasma has a specific energy frequency, basically, the rate at which the plasma vibrates. Kind of like the shields in Dune only much more so. Only things going really really fast are going to be repelled by the lightsaber shield, anything with lower energy will pass through the force field and be exposed to the plasma. This is consistent in the movies where the light sabers can be used to deflect blaster shots, other light sabers, but pass right through everything else effortlessly.

Obviously, this is total BS, but then, so is a telescoping ceramic plasma torch, so...

Higher Frequency punches through lower frequency like a bullet through wet tissue paper.
And, if you didn't notice, the Light Sabers didn't just harmlessly pass through the other matter - it made a hole at the contact point. Also, it was solid enough for Little Annie, Obi Wan, and others to just cut holes through several feet of doors that can resist heavy blaster attacks and be left with only nice dark spots and some dents.

 

[Unwardil]

Well, what I'm saying though is that the containment field doesn't do any of the cutting. That's the high energy plasma inside the containment field, after all, when the millennium falcon passes through the atmosphere containment shield thingy, it doesn't get sliced to ribbons.

That would explain why the jedi can get very very close to the blade and it doesn't seem the least bit hot, yet when they stick it into a door, the thing melts easily. It's only hot once you pass material inside that narrow containment field, outside of that, it's cool as a cucumber but that containment field only appears to be solid when it comes in contact with other very high energy things. To anything at a base energy level, it's insubstantial.
