How a real lightsaber might work ?

[Emperor Devon]

Who cares what purpose it will serve? I just want a lightsaber, I discover a purpose once I have it.

 

Civilians should be allowed to possess one of the most hazardous weapons ever invented? Lightsabers would be impractical in a war, but they would be very dangerous for people to own. That's just begging for trouble.

Give up already E_D, despite the odd fact that we actually agree on something, that something being the fact that a "real lightsaber" is impractical and that there are better things to do with your time, it is obvious that neither of us nor anyone else can persuade him otherwise.

[Hayden Kered]

I think the words "I want a real lightsaber" has just built up inside of windu6 for far too long.

You could use the saber to finally beat Jae though. How long have you guys been duelling? Years?

And what's an Emperor without a cool weapon?

Not realy. Everything is possible. Look at anti-matter or parelel universes*. If you think of the possibilities...

Then again...

The universe is endless huh? So there's a good chance, that somewhere in that neverending space are actually people wielding lightsabers. The universe is endless, so there are endless possibilities. Combine that with the parelel universes, and you have a whole lot of options

 

*Parelel universes=A theory. it states that for every choice everyone makes, another dimension is created in which you make a different choice. For example: I drunk some ordinary milk this morning. I could have grabbed the chocolate mil too, though. That makes 2 universes. So there could also be an universe in which the Germans have conquered everything, because, for example, the Germans saw through D-Day and defended the beach succesfully. Neverending possibilities.

No, Bane I'm just a Star Wars fan who just happens to know physics and mathematics, and who will like to have some of the Star Wars technology to be realisted.

Their is some serious science in Star Wars.

 

The Force: may be explained in terms of Quantum entanglement.

The lightsaber maybe become real because of the physics of cold plasmas.

And of course the the space travel technology is being consider to be a possibility by some scientists, but they need to speed that process up.

 

Hard core Star Wars fans should consider these possibilities.

Well I guess one day we will find out.

 

As for the Force, I always have believed that our instincts are very similar.

 

Yes they need to speed things up on space travel. I WANT TO LIVE ON MARS NASA!!!!

[Cygnus Q'ol]

Yeah, OK, maybe you could get to the point of controlling plasma.

Not probable, and not for any length of time, but possible.

 

The energy it would take would require a generating system of great power.

Where would that go? in your back pocket?

 

It would be entirely too large for portable use effectively unless you had a big generator on wheels or something.

Yeah that's it, a lightsaber car.

 

It is quite unrealistic and is closer to impossible than possible.

 

I can see you've put much thought into this and I applaud your tenacity, however it might be beneficial to try some of the decafinated brands on the market.

[Windu Chi]

You must haven't been reading my posts carefully, cold plasma is the key to the possible stability.

The energy it would take would require a generating system of great power.

Where would that go? in your back pocket?

Very funny!

I said, nuclear fusion or antimatter power cells.

There is great energy density in both many times more in antimatter.

Yeah that's it, a lightsaber car.

You are completely wrong.

Nothing is Impossible!

This is no joke, I'm serious about this as I'm serious about the physics of it.

You can laugh all you want, but lightsabers are possible.

And they will be a real technology one day.

[Cygnus Q'ol]

So you're saying that you could produce cold fusion with a couple of "AA" batteries or something just as small?

 

Hardly.

 

Like you said, you'd need some type of very small nuclear fusion power cells.

I forgot, where do we get those again? Radio Shack, yeah that's right.

 

You are also telling me that it's possible to handle a beam of (cold)plasma 1,000 degrees inches from your hand? shock1

I'd better wear my oven mitts then.

 

You sound like you're trying to tell me that two blades of plasma will cross each other and "clash" or better yet that two blades of plasma will have the exact same frequency and maintain it during power surges as the blade encounters objects and loses energy.

 

I'm sorry, but I find that hard to believe.

 

But hey, don't let me stop you from dreamin'.

 

...and what pray-tell would your focusing lens be made of?

Wait let me guess, Cortosis?

[Ztalker]

He never said that. Only that it's plausible (if not possible) to create a 'beam' of 1000 Degrees that can be wielded without the usage of a car with a generator.

 

Of course this stuff can't be done any time soon. We'll be long dead before it might even be investigated. But physics aren't bound by time. Only ones mind is

If could built a lightsaber now, I would have one.

I'm talking about the near future.

.

Superconductivity material and magnetic coils can store energy/heat energy; no resistance no heat loss from the coils or material, so hot heat can be block or slow to a safe hilt handling temperature.

I never said, ''cross each other''.

The cold plasma sheath will act like a shield that won't allow that to happen.

As long as energy from the power cell can properly maintain replacement energy the two plasma blades won't diffuse through each other.

Well, just like the movies, the plasma blade interaction will of course, loose energy from the power cells, but it is a lot of energy in a small amount of fusion material and antimatter.

The the frequencies variation will vary a little but a cold plasma is vary stable to energy interactions.

The resonating field that will be set up of course will have some variation, but if the power that is loss is replace in proportion to the potential energy resonating field decrement, then the clashing blade action can be safely maintain.

 

 

...and what pray-tell would your focusing lens be made of?

Wait let me guess, Cortosis?

When the hell did I say Cortosis lens; I said a electric field lens, strong enough to properly maintain the focus of the plasma gas stream.

Sorry but I have to go back to the link that I first posted:

 

The French aerospace company Aerospatiale has a plasmatron, or plasma generator, whose torch measures a metre in length. They use it to test re-entry conditions on materials for their Hermes space shuttle. This baby goes through 6 megawatts of power and calls for few cubic metres of gas per minute [1 cubic metre=1000 litres]. The equipment to operate it weighs several tons. They have plans to develop a plasmatron that would be several metres long, but which would require 120 megawatts of energy (of which 50 percent would go to the cooling system).

 

A plasma gun at Aerospatiale in France.

 

Plasma sabers have technicaly been created:

This AC plasma torch uses 125 to 750 kilowatts and generates a temperature up to 8,000 degrees Celsius.

 

Seeing how much power takes to just produce a 1 meter torch, we are far from making movie sabers.

 

 

Plasma guns that we use today are extensively water- and gas-cooled. They also thrust vast amounts of gases through them to obtain a jet. One researcher suggested that miniaturization had come to the point where you could get a 10,000 degree plasma jet about ten centimetres long from forty kilowatts of power in a unit that would weigh something reasonable, but it would require about 50 litres of air to be pumped through it per minute.

2,808,333 times more energy in comparison 337.664396396785 TW/120 megawatts for 1kg of deuterium and tritium fusion

Now for 0.337664396396785 TW/120 MW=2,813 more energy for 1 gram of deuterium & tritium fusion reaction.

 

Plasma sabers have technicaly been created:

This AC plasma torch uses 125 to 750 kilowatts and generates a temperature up to 8,000 degrees Celsius.

2 grams of antimatter will have 179.750269488251 tera watts of power

deuterium and tritium fusion: 1kg of this fusion process will produce 337.664396396785 Tera watts of energy or power if flow for one second and 1 gram of this fusion process will produce 0.337664396396785 Tera watts of power.

Billion times then enough energy need to power a plasma blade.

Also that is a hot plasma, less dense, more ionize and more diffuse, so more unstability in maintaining of structure for the lightsaber's blade plasma length.

Also being more ionize then a cold plasma the plasma gas stream will flutter chaotically as it looses magnetic energy because of electrostatic ionization, so the energy needed to maintain the magnetic fields for proper gas dynamics and electrostatic field attractions, that holds the blade structure in place will have unstable energy flow rate to properly maintain the blade length, temperature and the proper plasma occilations(electrons and ionic frequencies), the frequencies that will determine the clashing blade repelling action physics.

 

You can't have a hot plasma gas as the only component to a real lightsaber because a plasma blade will be more diffuse, so it is less dense to properly entangle the magnetic fields to maintain the blade shape.

Or, the resonating field effect can't be set up to be stable, in a hot diffuse plasma.

 

Also again, the clashing action will not be maintain troughout the plasma blade length, because of the more ionize properties of a hot plasma component, will not maintain the same stable temperature, plasma frequencies, magnetic field densities to cause a stable potential energy base resonating field throughout the entire plasma blade's geometrical structure.

And it will be hard to lower the heat conductivity of a hot plasma gas to safer temperatures for safer use.

Because by a hot plasma gas being more diffuse, the magnetic fields inside and throughout the blade's geometrical shape won't be completely stable(the magnetic field densities will vary randomly) to safely control the heat flow rate, between the plasma gas and the outside environment.

Seeing how much power takes to just produce a 1 meter torch, we are far from making movie sabers.

We maybe closer then you think.

Also another meter we can construct a staff lightsaber weapon.

But that energy value is no problem for the high energy densities in deuterium and tritium fusion and the 1,000 times more energy in grams of antimatter reactions.

[Cygnus Q'ol]

My point is that even if you could produce and control a plasma blade for any length of time, which you can't, it would take more energy and equipment than anyone could carry around, cold or hot.

 

I guess to me, that's what makes it ridiculous.

They call it fiction for a reason, ya know.

 

Perhaps in a century, I'll be proven wrong.

I'll be too old to weild one by then anyway.

[RC-1162]

aww, come on Cygnus, leave the dude alone. i personally find his arguments to make sense. of course, nano technology is the 'in' thing now. who knows? maybe in another 50 years lightsabers will be used in fencing competitions instead of those bendy thingies

[Prime]

I think it is pretty clear that they won't be.

[Windu Chi]

I think it is pretty clear that they won't be.

Do you possess precognitive abilities?

[Det. Bart Lasiter]

Do you possess precognitive abilities?

Everyone knows Prime has been cursed with them since that accident at that radioactive place.

[acepilotf14]

I only believe we will make fake showy sabers... That will make the sound, and look just like a SW one, but it wont cut anything and all it does is faze through things.

Saber= Fun toy!

And maybe we can make them clash with eachother. But.. the plastic ones now... hurt...

[Windu Chi]

My point is that even if you could produce and control a plasma blade for any length of time, which you can't, it would take more energy and equipment than anyone could carry around, cold or hot.

Well, Cygnus if I could create a plasma blade now, do you really think I will be here explaining the physics of a lightsaber?

 

I guess to me, that's what makes it ridiculous.

They call it fiction for a reason, ya know.

Well, you believe in impossibilities, I don't believe in impossibilities.

So, I guess it will remain a ridiculous idea to you if you maintain that belief.

Also, a lot of the technologies we have now, was once consider science fiction.

The lightsaber is only fiction in the mind of people who consider science fiction ridiculous, not me I believe any form of science fiction will be a reality one day; if the scientists of this planet only open their mind to the infinite possibilities in existence.

And stop being close-minded to strange ideas.

 

Perhaps in a century, I'll be proven wrong.

I'll be too old to weild one by then anyway.

In my opinion, its a high probability you will be proven wrong.

[Cygnus Q'ol]

You know what windu6? You are absolutely right.

 

Please except my humblest apologies.

All of the technology we now use and take for granted today, was at some point, just and idea.

 

If you went back a hundred years and explained how things are today, you'd probably be locked up.

 

I think of all the medical, flight, space, construction, meteorlogical, oceanic and transportation technology that has come from thinkers and dreamers just like you who just will not take NO for an answer.

 

Great Job! Don't ever let anyone tell you that you can't do something. And sorry for giving you such a hard time. I'm a dreamer too, but at my age, I'm a realist also.

 

...and thank you for helping me keep my mind open.

If you let it, age and stagnation can close and lock doors to your mind and imagination.

 

I still believe it will be some time before plasma technology will be avaliable in the capacity to be handled like our favorite movie, but you've opened my eyes to the fact that there are those out there that will not rest until they've figured it out.

 

Maybe it'll be you. Keep studying and MTFBWY.

 

Godspeed!

[Darth InSidious]

I think the real question is not the physics of creating lightsabres, but whether we need, or even want lightsabres.

 

Think of what destruction and terror could be wrought if just one fell into the wrong hands.

[Vaelastraz]

 

In real life, we have .50 Baretts that shoot huge bullets traveling at the speed of sound. Good luck bouncing those back. Unless firearms will be replaced by laser-guns with the same physics of that in the Star Wars universe (slow lasers) I highly doubt the weapon will be efficient enough for seld-defense or military usage.

 

Well, who says bullets would be paried by a lightsaber anyway. The time they'd be inside the blade would probably not enough to ehm disintegrate them.

 

And our lasers... they move at lightspeed. Completely impossible to pary those.

And besides... plasma does not reflect highly intensive focused light does it?

 

A mirror would do it... at least for the not so super hot lasers.

 

 

Now I read through all of that lightsaber physics explanation, still, I don't seem to be able to understand how that can work. To me it looks a bit like the attempts to keep nuclear fusion going. You need an electromagnetic field, strong enough to keep the super heated material inside. That would need insane amounts of energy.

Even if I that theory with cold plasma did work, where do you take the energy it demands from?

[Windu Chi]

Well, who says bullets would be paried by a lightsaber anyway. The time they'd be inside the blade would probably not enough to ehm disintegrate them.

In my studing of the physics of a cold plasma, this kind low ionizaton and high density plasma gas.

Can be made depending density of the gas to act like a bullet shield, with proper adjustment of magnetic flux density for high pressure tension between the electrons and the ionic material.

 

And our lasers... they move at lightspeed. Completely impossible to pary those.

I'll just say this, "Nothing is impossible".

And besides... plasma does not reflect highly intensive focused light does it?

Depending on this density of the cold plasma sheath and magnetic pressure tension force, that hold the plasma structure.

The energy density of the photons(in the laser beam), if the photons EM wave frequency is about the same as the electrostatic field oscillation or cold plasma frequency of the electrons and the partial ions of the cold plasma.

The laser beam photons will reflect off the complex interactons of magnetic and electric fields of the gas plasma particles because of the the electrostatic potenial field frequencies and relative electrostactic field value amplitude of electromagnetic field in the plasma gas , in which the laser photon field in the EM wave, will have to match same EM field frequency cold plasma sheath to reflect laser ligh off at about a 90* angle.

A mirror would do it... at least for the not so super hot lasers.

The cold plasma component sheath, depending on the EM field parameters also density of the gas, will act like material similar to polish mirror reflectivity material.

 

Now I read through all of that lightsaber physics explanation, still, I don't seem to be able to understand how that can work. To me it looks a bit like the attempts to keep nuclear fusion going. You need an electromagnetic field, strong enough to keep the super heated material inside. That would need insane amounts of energy.

Even if I that theory with cold plasma did work, where do you take the energy it demands from?

The energy will either come from nuclear fusion or antimatter reactions in the power cell assembly.
