How would a light saber really work?

[Nicool003]

well since this thread isn't in How Stuff Works yet, and it was put in Technology as a ''somewhat'' duplicate let's start off fresh.

I'll ask these questions although we discussed them a lot in the old PF for all those who haven't seen the thread I will start it off


"do you think it is possible"

"why"

"how"
"do you have any ideas as to how it would/should/could work?"

Are u kind of addicted to this stuff Nicool ?
J/K.
Well i remember lot of good ideas were presented in the original versions of this topic.

"do you think it is possible"

I personally think it is not possible as is (like in movies).
But a very similar weapon can be made.

"why"

Because there are lot of promising technologies that could be used

"how"
"do you have any ideas as to how it would/should/could work?"

The best idea i see so far is the idea of having more than a single EM wave source, that will make EM waves that cross at a certain (adjustable) point.
The EM wave itself will be harmless, but at the point of crossing of the two EM waves intersections between waves will happen to produce a new wave that is harmfull (only at that point).

Some technologies could be used to make several points, or maybe a line of those points.

True I like star wars...and the technology in it!

Yes in the last thread i believe FZ suggested plasma but as he said (and I quote)

"there are three problems"

1) The handle would get rather *hot*
2) It would glow like a dun and blind poor obi-wan
3) It would parry other sabers but at times would not be so "efficient"

And maybe ... it will be too heavy ?

 

[Nicool003]

perhaps but perhaps not. It could be another form of plasma or perhaps a type of laser. There were many ideas but I am pretty busy now and won't be on PF for long so I will post them later.
