if the light sabres are magnetically charged then they will resist the motion of another light sabre, also more nanotubes = more power, more power = higher damage.
just how powerful does it need to be to kill? that's all the power you need. and finally, why not have it in different shapes? a light sabre wit ha hook at the end would be EXTREMELY annoying to your enemies
i have no idea what any of the wierd stuff is but wont it just snap if you hit another lightsaber and the proper power source is a crystal from planets in the star wars
there's only one problem that i can see, ceramics are very fragile, if you drop you lighsaber you risk breaking the ceramic blade.... unless the ceramic itself was strenghtend with something...woven carbon fiber perhaps?.... No, because the problem is still with the fragility of the ceramics...you would essentually be fighting with florecent lightbulbs smack em against each other, and the shatter.
I don't want to be close to anything that generates 15MW heat. Not to talk about the ~100 cubic feet/sec blow through that fan. Not just that thing sucks. The airflow will speed up exchanging heat nearby you, literally everything would evaporate around. Except those sexy ceramic cylinders.
nono tubes would still need step up coils/crystals to amplify the energy from the power source or would not the batteries be drained in an instant?
instead of trying to build this with todays technology, design it for yet to exist tech and wait. like the nono tube part. i'm sure combining all of the ideas in this video practical designs could be realized using pieces that have functions but yet to exist. no one would have guessed stopping light or growing nano tubes.
The problem with a battery holding that much energy is that it creates the potential for the catastrophic and uncontrolled release of that much energy.
A laptop battery contains potential energy on the same order as a hand grenade, and people have been killed trying to open them up before. Pack the sort of power he's talking about into a man-portable device, and what you end up with is a suicide bomber's dream come true, with catastrophic release potential second only to a nuclear explosion.
A proper design should use a telescopic alloy blade core with a magnetic field plasma barrier. The blade could be made of titanium-cobalt-tungsten alloy, really hard and heat resistant. The ceramic should be in the form of coating, not for the entire blade body. There's no need for a turbine fan, as the charged particles can come from the actual air particles surrounding the blade. The energy source can be a super capacitor. The cutting comes from the plasma, not the blade rigid body underneath.
Dr. Kaku! You should know better! Your design for the lightsabre fails to give us an answer just how your small fan can move 100 cubic feet of air per second. I know this is all theory and such, but if you want to apply futurist views of reality to one part of your design, you have to apply it to all the design.
This was retarded. If you turned it on in a closed room, you'd be cooked straight through within 10 seconds because of the power output would all be converted to heat. It's not a lightsaber, it's a bomb.
it may take 50 megawatts to cut the metals but not even a fraction of that to cut through your fellow human. being that the bodies elements are composed of much weaker bonds.
@Themayseffect Convert 50 megawatts for one second = 239 kilocalories or about 950 BTUs. There's about 100,000 BTUS in a gallon of gas. I.e. in less than 2 minutes, the equivalent of 1 gallon of gasoline's energy will be dumped out.
Use it in a room, and it will burn it down quite nicely, whether you touch anything or not.
@fuzzywzhe i see your point and can i agree to it. but i dont understand how you linked that fact with what i said? i merely suggested that it (DOES NOT) take anywhere near 50megawatts to cut through human tissue or bone. matter of fact if you tried harnessing 50megawatts or any respectable amount near that level in a closed room, the user and the opponent are the closest energy source for 50megawatts to send its power. thus it will fry you both to particles, in less than a second!
@Themayseffect I was just immensely annoyed by the science that was ignored.
I'm not a physicist and I can see this wouldn't work even if all the available materials were available. I'm an engineer, and some dumb ass PhD ought to know freaking better.
@fuzzywzhe i hear you loud and clear on that, but i'm sure some of the knowledge that isn't being shared is something the engineers on the show would consider "top secret" or to complex to explain in 5 minutes to the average fan-boy. Its clear that this guy is sharing half explained information or extremely dumb downed info so that the viewers can have a vague idea of how these things might work.
Only people trained as Jedi should be able to own one. I could just see all the self inflicted wounds from this from all the wannabees just practicing.
and what if you use magnetic force to keep plasma gas with the shape of a saber and also you use it to repulse your foe's plasma...so it will be not solid, but it will be solid only saber vs saber, and not saber vs stormtrooper! :)
Does anyone know if the special ceramic is obtainable currently? Also, if you had to tone down the power of such a device, would it still be powerfull? if instead of cutting through metal like butter you were to settle for slicing through a human like butter how much power would that take? Or if you were to settle for setting a human on fire on contact? (Trying to get info for a role-playing game. The "free energy" i can generate is measured in houses; on a brilliant roll i'd be lucky to get 10)
The air would get really hot if there was super hot plasma a few feet away, AND sucking all that air through the blade would mean it would be very hard to breath where the plasma-saber was used.
50 years or so to get nano batterry tech and unless you build it yourself I doubt you'd be able to get a lightsaber due to it being such a powerful weapon :P
ancient lightsabers actually had power packs until they made a certain battery to power it. somehow the magnetic field that holds the plasma in the lightsaber also move the power is generates in a current which recharges the battery, unless the current is broken when you slice through something. so essentially you only need to replace the battery after cutting through multiple objects.......or people :p
It wouldn't work in an airless vacuum: no gas to create the plasma.. A light saber would have to work in space. I like the laser lance thing better, it would be far more effective.
cut anything, but another light saber. but wouldn't the ceramic break? well ofcause if by then nano batteries are invented.. i am sure ceramic by then would be as hard as diamond :/... or SHOULD be..
Actually having an external power source would not be against Star Wars. The Ancient Jedi had battery packs on a belt with a power cable going to the blade.
@MegaMrRice perhaps time travel has been accomplished, and star wars was a creative make up for profit by the traveler who got stuck? Cows go - teehee!
@kroqgar78 A metal bullet would pass through the energy blade, melt into hot melted slag or hot metal gas/liquid and hit you in the face/body, I'd personally prefer to get shot... Seriously.
during the sword clash, wouldnt the ceramic break? then you will need another huge energy source, making the lightsaber completely useless. I thought Michio Kaku was an amazing physicist, but now Im beginning to think that he is heading towards the science fiction business. Should be careful with that barrier between science and science fiction.
@250666bmf not all ceramics are weak per se. he could have used the carbon nanotubes instead of ceramics too, those things formed into a large structure (like a tube with holes in it) is stronger and more flexible than any metal. and i guess it'll withstand crazy temperatures like any carbon. (diamonds, ashes, panels of a new Lamborghini... all carbon in a different config)
Very true. I think at this current time humanity thinks of itself as incredibly advanced, at virtually every possible Earthly pinnacle imaginable. 400, maybe 500 years in the future, I bet humanity will look back at our time and see us sort of like how we see the Renaissance. Incredibly advanced compared to earlier years, but still seen with a primitive quality. And inferior technologically as well.
'Back then, laser-guns were mostly science fiction, but nowadays...'
@guitartuner Thats like me saying to you, "In the middle ages, they tried to turn base lead into gold, but now... THEY STILL CANT DO IT". It is YOUR argument that is invalid. Stop living in la la land, light sabers like in the movies isnt going to happen. Get a job, and a girlfriend, then move out of your Mothers basement already!
wouldn't ceramics break and a plasma wave burn all over us after a sword collision?? and even before that we would be in a special thermal suit and gloves to hold 15k+ C.
@Ninjapcx technically, you are right. theoretically,though, the plasma heat keeps the ceramics from touching. you are right, because even then the ceramics would probably break from the shock of being stopped by the heat. also, didn't he say that the ceramics would only withstand 4000 degrees? then he said that the lightsaber would be 12000 degrees.
@MegaBlackhawk12 exactly totally agree ..well ceramics are hard but breakable and they will melt, considering the outrageous technology Kaku came up for this project, we will probably got artificial nano-materials by then..and who knows what else, anyway the time we will got this technology in our hands we can build flying saucer not a lightsaber xD
@Ninjapcx Plasma would only do that if it not contained and you make it to where it stays around the ceramic tube. And it depends on how hard you make the collision with the ceramic.
It seems to me that having a 1.21 gigawatt battery or power source in your hand or pocket would be all kinds of inconvenient. Just picture how bad it'd hurt to flick that thing on and have a little piece of the Sun mere inches from your hand. And that's ignoring the convective and radiant heat.
@Amigo21189 I've got one in the back of my vehicle, and it's not that uncomfortable. It only gets real hot when I travel real far back or forwards into time.
The powersource mabey trillions of nanotubes that will make tubes not unless box shapes. But these are good for conducting electricity. The electricity is questionable on what it is guna be but that is some of the basics.
So if you shoot a short beam of laser out at somebody you can just kill them, but like I said it has to deal with the thickness of the crystal lens. This can also cause you to blow up a building with a short beam of laser. A long beam of laser can be used to cut things in pieces, dig, so on and so forth. And it also must have a power source and thick crystal lenses zig zagged before it gets to the thick cone lens.
For some of you that did not know this but homegrown crystals are a major part of a pulse laser or pulse laser gun. The crystal lens depending on how thick it is will make the short beams that you shoot out of the laser or the whole beam that can come out makes it stronger and more powerful.
My only problem with theoretical physicists is this, they don't actually DO anything because they have SO MUCH TO DO. It's not their fault... they just can't.
@MrVader95 Did you really expect a real working a lightsabre at the end of this? The first half of the title of this show is SCIENCE FICTION. Why do we just get 3D models? Because (as was pointed out in the video all too frequently) making a lightsabre with today's technology is impossible. It simply can't be done. The point of the show is both to show that these things might one day be possible as well as to give us an idea about how they might be constructed. Which I find very interesting.
if the light sabres are magnetically charged then they will resist the motion of another light sabre, also more nanotubes = more power, more power = higher damage.
just how powerful does it need to be to kill? that's all the power you need. and finally, why not have it in different shapes? a light sabre wit ha hook at the end would be EXTREMELY annoying to your enemies

Stop living in la la land, light sabers like in the movies isnt going to happen. Get a job, and a girlfriend, then move out of your Mothers basement already!

@TheMedievalMan actually you can turn lead into gold today.... but the energy needed to just create the smallest amounts outweighs the process.

1. Ceramics will nut burn in plasma, hence your sabre will not cut through another saber.
2. Ceramics are very hard and therefore brittle.
What do you think happens when 2 light sabers of this design collide?
Hint: Have you ever dropped a cup?

wouldn't ceramics break and a plasma wave burn all over us after a sword collision?? and even before that we would be in a special thermal suit and gloves to hold 15k+ C.

@Ninjapcx technically, you are right. theoretically,though, the plasma heat keeps the ceramics from touching. you are right, because even then the ceramics would probably break from the shock of being stopped by the heat. also, didn't he say that the ceramics would only withstand 4000 degrees? then he said that the lightsaber would be 12000 degrees.
MegaBlackhawk12 2 months ago
@MegaBlackhawk12 exactly totally agree ..well ceramics are hard but breakable and they will melt, considering the outrageous technology Kaku came up for this project, we will probably got artificial nano-materials by then..and who knows what else, anyway the time we will got this technology in our hands we can build flying saucer not a lightsaber xD

@Ninjapcx Plasma would only do that if it not contained and you make it to where it stays around the ceramic tube. And it depends on how hard you make the collision with the ceramic.

It seems to me that having a 1.21 gigawatt battery or power source in your hand or pocket would be all kinds of inconvenient. Just picture how bad it'd hurt to flick that thing on and have a little piece of the Sun mere inches from your hand. And that's ignoring the convective and radiant heat.

@DjaNN33 Mohs hardness is not a good indicator of whether the material in this case. Tensile strength is what is needed.

The powersource mabey trillions of nanotubes that will make tubes not unless box shapes. But these are good for conducting electricity. The electricity is questionable on what it is guna be but that is some of the basics.

So if you shoot a short beam of laser out at somebody you can just kill them, but like I said it has to deal with the thickness of the crystal lens. This can also cause you to blow up a building with a short beam of laser. A long beam of laser can be used to cut things in pieces, dig, so on and so forth. And it also must have a power source and thick crystal lenses zig zagged before it gets to the thick cone lens.

For some of you that did not know this but homegrown crystals are a major part of a pulse laser or pulse laser gun. The crystal lens depending on how thick it is will make the short beams that you shoot out of the laser or the whole beam that can come out makes it stronger and more powerful.

For those who wonder about the ceramic element being brittle...
A ceramic blade made of zirconium dioxide scores 8.5 on the mohs scale compared to 6.5 for hardened steel and 10 for diamond.
Ceramics doesnt only mean kitchen tiles or flower pots.
Although I have made extremely hard stoneware plates in 1400 degrees celsius wood fired kiln.

Awesome idea but one problem is that unless they strengthen ceramics you can't clash light sabers.

My only problem with theoretical physicists is this, they don't actually DO anything because they have SO MUCH TO DO. It's not their fault... they just can't.

MrVader95 2 months ago
@MrVader95 Did you really expect a real working a lightsabre at the end of this? The first half of the title of this show is SCIENCE FICTION. Why do we just get 3D models? Because (as was pointed out in the video all too frequently) making a lightsabre with today's technology is impossible. It simply can't be done. The point of the show is both to show that these things might one day be possible as well as to give us an idea about how they might be constructed. Which I find very interesting.
