What are the technological hurdles to building a real light saver

fuck you Steve jobs

A guy already made a very weak one http://todayinawesome.com/blog/2015/12/17/the-guy-who-made-a-real-mjolnir-is-back-with-a-real-lightsaber

That's an overdriven laser diode, I would hardly call it a lightsaber

>>7748371
Just for the record, Kylo Ren was a little pussy ass bitch.

>>7748382
thats not a lightsaber its a fucking glorified zippo

Just swap your incandescents for LEDs and call it a day

>>7748371
The biggest technological hurdle would be having to work around the whole "a force in motion tends to stay in motion" thing.

>>7748371
4chan is too full of autism to do anything worthwhile with science.

>>7748547
or having a more or less scientific discussion about fun subjects like this one.

/sci is the most autistic board right after /a/.

>a real light saver

Well first we have to define what that is. Does a blowtorch count? If not, why not?

>>7748511
Magnets.

>>7749018
nope, fire goes through fire

>>7748371

Why do we need lightsabers when we can use bullets instead?

>>7749040
Oh, so you want it to have a temperature of plasma but still solid to bounce off objects? Not gonna happen buddy.

>>7749043
I mean, if you can build a working lightsaber such that you basically just have a length of energy/plasma/laser/whatever the fuck it is you can certainly branch that tech to other devices

such as better bullets.

>>7749056

I very much doubt that lazer projectiles will ever become as efficient as a good old fashioned bullet.

>>7749113
Assuming your power source for the blaster was efficient you could fire way more shots with a blaster than you could than with a gun.

Also they would be a lot more accurate especially over long distances.

>>7749294

>blasters
>more accurate

Have you ever seen a Star Wars film?

>>7749482
Watch the new one faggot

>>7748371
Isn't it mainly because you are trying to turn plasma into a non newtonian material?
No to mention how to limit the blade in size?

A vibroblade is much more likely

Depends on what you want the blade to be made of... plasma being the best bet in a housing of some sort that can shape it. Powering it is another matter entirely.

You would have to have some sort of tangible magnetic guide that would keep your plasma stream limited to the length of the blade, provide you a solid object to bounce off of, and would retract into the hilt. Also, what kind of micro power source are you going to find to manage all this? And how are you going to keep the magnet from interacting with every other damn thing in the area? Lastly, I think your plasma would bleed off every time you made solid contact with a physical object. So no, you can't make a lightsaber. If you could actually build the damn blade/plasma emitter, you'd have to lug around a fair sized power plant to plug it into.

A proper laser weapon would probably be superior to bullets in certain situations, such as shooting down aircraft.

>Not powering your lightsaber with midichlorians

Do you even Star Wars?

Like most small futuristic items, the problem lies in power. Our batteries are shit and will be shit until a new breakthrough is made.

You could rig up some sort of device that ionizes plasma and vents it off and around a ceramic rod - and it'd pretty much be a lightsaber. You'd just need a power plant to power it.

>>7749294
They fire at only 100 mph

That slow as shit and could easily be dodge by an enhanced human.

But you cant dodge a bulet

>You would have to have some sort of tangible magnetic guide that would keep your plasma stream limited to the length of the blade, provide you a solid object to bounce off of, and would retract into the hilt

You know, just watching the movies they could totally have that part that retracts and we just never see it

>>7749054
They only need to bounce off of each other, to allow for fencing. They cut through any other objects*.


*yes-except for certain obscure in universe alloys, we're trying to make a lightsaber, go to /tv/ for that kind of trivia.

Who is gonna win fool?

>>7753238
Just because darth vader has that whole armor thing going on, if it was against Luke....
Luke would be demolished by any automatic rifle

Well, firstly a light saber would probably not be made of laser light but instead be a focused and small bit of plasma molded into a phallic shape.

You would have to find some sort of force that could mold the plasma into that specific saber shape.

Then you would have to find a way to make the light saber halt when it came into contact with another saber because by default the two sabers would just pass through one another.

have fun melting magnets and rendering them useless

>>7748382
looks pretty easy to build

>>7748382
That looks cool as a fuck.

the only reason its good is because of logistics
Most of the military is fucking logistics. Transporting supplies to the front. And bullet takes up most of the logistics capacity. If you have laser weapons, YOU DON'T NEED BULLETS!
imagine not having a supply chain to deal with. Basically half the military logistics can be removed and allocated into other fields.

It'll also be a game changer in insurgencies. You have one of these guns, you don't need a supply of bullets. you take one, and you don't need to go raiding into places to get bullets. Just camp in the forest sniping people. Imagine if Simo Hayha had a laser gun. He just shoots as much as he wanted at the Soviet, no ammo conservation needed.

Man portable laser guns would change the world.
