is jedi's lightsaber possible to make?

[JonB]

Hmm - string. Hopefully you aren't implying simple cotton thread, but something more elegant, more geeky. Perhaps thread made of mono-crystalline fullerene. That could slice some cake!!

well, speaking of diamonds, what if you had a solid diamond blade that was heated to like 10000 F. See, you hook it up to this AC adapter from Dell, that should get it hot enough. Of course, you're going to need some mean shielding to protect yourself from the heat, but I'm thinking this baby will slice right through anything it touches...as well as incinerate your environment in a huge radius as you walk with it.

Diamond is carbon. In the presence of atmospheric oxygen, it burns at a temperature somewhere between 1500 and 1600 degrees.

If you can make light that strong you better wear your sunglasses.

Edit: and lightsabres do have mass. It's plexiglass and fibreoptics.

You could theoretically use a nuclear fusion reactor, which uses plasma to create a surplus of energy, and eject the plasma with almost no force, and since it would be free electrons, you could focus it, and use the other pole of the plasma beam to attract a high temperature magnet, made of a substance like the following:


.-.-.-.-.-.-.-.-.-..
:_:_:_:_:_:_:_:

Which would end up reflecting the free electrons back at the origin, supposing it was perfectly straight, and all of these, in turn, would make a lightsaber.

Crap. I already went out and bought a solid diamond rod to make a light saber...I hope Walmart will refund me, otherwise I'm out $630,000,000.

*sigh*

Just coat it with boric acid like the jewelers do to seal it from oxygen. Didja ever notice in science fiction that they never stick their light sabers in water? Don't want to dissolve that special coating, now would you?

Also, synthetic diamond technology has come a LONG way. For a fraction of the cost above, you could be manufacturing gem quality diamonds in mass quantities. Even more perfect than gem quality if you so desire. Diamonds are cheap and my friend. De Beers has artificially maintained a *VERY* profitable supply and demand balance.

first off, it's not just the crystal, but the unification of the force with oneself allows the user to actually control the energy. Second, the sparks and stuff you see are actually the effects of two concentrated forces colliding (i.e. Luke's force with vader's), not the actual light itself.

So in order for us to harness light itself in such a way, you need the force. Which is fictional and totally made up. So no, you cannot harness the power of a lightsaber unless you are one with a nonexistant force

do or do not, there is no try -yoda

Ok, while this overall is a funny and light thread... this one was just too stupid to let pass.

In the canon of the MOVIES, the force is not required to ignite a light saber. (Han uses one, remember?) That force is required bullshit is made up to explain why no one else carries around a really cool looking sword. (Which ignores the reason why WE don't walk around in war with swords instead of guns... namely, it just makes you look cool while joe soldier shoots you dead from 500 yards away).

and if it's possible, would you get the effect of a light saber hitting another light saber (sparks flying etc)? since light is mostly waves and photons, shouldn't it just go 'pass' through?

ps: i'm just excited from watching star wars ep3 trailer =)

That sentence should have ended with "I've read from a star wars book" Seriously if you are talking about just "light" then there is absolutely no way to do this. A beam of light is nothing more than a stream of photons. You could certainly focus a beam of light with a crystal and create a light sabre "effect" but it would never have any "substance" by itself. You could certainly create a laser sabre that could inflict damage but again it would have no substance and hence you couldn't use it like a sword.

EDIT

 

[StealthElephant]

Same thing

 

[bwanaaa]

I have thought about the plasma contained by a magnetic field as mentioned above. A plasma generator is the tricky part--needs a lot of energy like maybe a small fusion rxn in the handle -How to achieve this? -> pulsed led laser bombardment of tritium? Laser amplification to terawatt levels has been recently demonstrated in the home using diffraction gratings to stretch the pulse prior to amplification and then another grating to recompress the pulse. By stretching the pulse, this allows simple laser amplification techniques without expensive massive hardware. Recompressing the pulse a million fold generates the power necessary to generate the plasma.

A superconducting ceramic electromagnet in the handle would operate near room temperature. This would confine the plasma to the central core of the field.
Since the plasma is being generated by pulsed laser induced fusion, the magnetic field would be generated by the same discharging capacitor that powers the led laser array. Alternating the field would provide plasma containment but negate magnetic attraction of neighboring magnets. The plasma trajectory (positive and negative charges)would be contained/focussed by the powerful magnetic field because of the intermittent and alternating nature of the magnetic field,

The pulse frequency would be high enough so that the light sabre would appear to be constantly on.

A Vibroblade is better than a lightsabre. A strand of wire is enough to cut a steel pipe, u know?

WRONG, light do have mass, as long there is photons, there are MASS.

 

[Stiganator]

wouldn't many of these ideas require a single poled magnetic field? The high energy plasma shooting out is (-) lets say then the (+) end the field would attract it back? what about he other end? wouldn't things with the opposite charge whip through the air and kill you?

you always see light sabers retract. They dont just shut off.


maybe there is a high speed retractable device at the center of the "light" saber...

now stay with me

mabe there is a very highly concentrated fuel cell in the handle, (and its triggered by the right frequency only emitted by certain lifeforms [the force]) and a method to convert it into gas while emitting it into the air throughout the high speed shaft.

Now all you need to find is a way to power this special gas that you can super charge into some kind light emitting super hot "light" saber.

although the light from the charged gas would probably blind you first.... lol

What if the handle contained some kind of material that stiffend and hardended when light was applied to it? And then Retracted back into the handle when the light was turend off? The would work and is technicly feasable (selenium).

 

[neutralizer]

Why do you ask Mr. George Lucas?

 

[deveraux]

Hmm ..here's a whacky idea (since this is a whacky topic anyway), why not use nanites? The hilt can be used to contain them, and when "activated", will be dispersed to form a light emitting yet solid "blade". Sounds plausible?

Umm...I hate to burst your bubble, but didn't han solo use luke's lightsaber when they were on Hoth.

GAWD! I'm such a nerd.

Bah. I'd rather have my level 3 force lightning anyways.

Yea you are correct ;D You don't need the force to turn on and swing around a lightsaber. You do need the force to use it effectively like the Jedi do though.

 

[gorcorps]

Wow, we have no lives...

Anyways I think some team of scientists tried developing a weapon that was supposed to "mock" the style of a lightsaber. I remember reading it in the news about 5 years ago or so. They were able to make a fairly thick laser beam out of a handle. The handle was massive though, the beam wasn't that thick, the lasers wouldn't stop each other like lightsabers, and of course they couldn't stop the beam at a certain distance.
