First of all, what is the liquid fuel that burns with the highest temperature possible? It must have a very high viscosity - able to fit through a hole a few microns wide.

Also, it must be able to be lit with a standard static arc (like those found in butane cigarette lighters).. or, I would need a small igniting mechanism that can attain super high temperatures.

I also need a material that can withstand very high pressure - I am thinking carbon fiber.



Then, I will need a rocket scientist (or physics major) to calculate how large a hole will be necesary to have the fuel burn off completely four feet or so after exiting the nozzle at 5000psi (or whatever pressure today's carbon fiber can handle.)

This is gonna be neato.

Picture so far: An inert gas pressures the liquid chamber. A microscopic nozzle lets out a thin stream of fuel at precisely the right speed to have it burn off completely about four feet from exit after being ignited by the arc switch which simultaneously opens the nozzle.

It's not going to burn of completely in such a way that you'd get a distinct "end".

...Why are you struggling so hard to get a blow torch?

Buy an industrial blow torch, they can have a flame as big as 6 feet if you increase the pressure.

11 posts.. 2 helpful.. maybe jagec's post and cashmoney995's post.

I would like more discussion on the topic I posted. It is annoying to filter through insults that phase nobody.

Wow, what an original idea. First you'll need a rocket ship to travel to Dantooine....

If you go thru w/your plan, you are OBLIGATED to make a video of yourself fighting with the lightsaber like the infamous "Lightsaber Kid" from about a year ago. It is mandatory.

This thread might go over better in the Highly Technical forum, if it's still around. You would probably get better responses than "repost" and "stab it".

Oh man this is a classic ROFL....

u do know that even if u do make this thing and it works as soon as you move the saber your blade is gonna bend HAHA lol....

you will have a bendy blade just like when u turn on mouse trails in the old windows 3.1x lol

pictures are a must dude... make sure u include some of you aswell so we all get to see who it is that is gonna make the ultimate in uber-nerd equipment :)

Read up on lightsabers. Read the books. They're a meter long, not four feet. And the saber itself isn't a pin point, it's fairly thick. Blah blah blah anyway...

all you really need is a harmonic phaser invertor and an isolinear plasma injector

@ 5000psi, I'm not sure you'd notice it burning. I'm sure you can get a fume to spray fast enough that if it moves around fairly fast on fire that you won't notice too much. It's the physical properties of the blade itself that he's going to have a huge problem with.

Why not just buy a parksaber??
