If you could have any sci fi device, what would it be?

Everybody should say Lightsaber cause its the goddamn truth everybody wants one.

I don't, LASERS DON'T JUST STOP!

Actually the "Light Saber" is very possible theoretically as a Plasma Sword. All we have to do is figure out the magnetic containment field for the Plasma to keep it hot inside but cool out side the field. Second comes a power source small enough to fit on a sword like weapon. Give it time and the military will figure that out.

Star Trek teleporters for sure.

Out of that, I'd reverse-engineer insane energy sources (since, well, it freaking converts matter to energy and back), replicators (did I mention the "and back" part about the E=M*c^2 thingy yet?), maybe even holodecks (since, well... they're almost the same thing anyway) and quite probably a host of other Sci-Fi technologies (not necessarily just Star Trek-ish) or serious improvements to some (more or less existing) technologies.

The Enterprise would be useful if it came with a power source.

All I need is the Holo Deck hooked up to a nuclear core. Like I said. Cash money in the bank baby!!!!

First, your very basis is incorrect: a plasma sword is not a light saber. It is comparing apples and very highly heated electron/proton gas, I mean, oranges. Light sabers supposedly use crystals and other such nonsense that sounded quite plausible back before all of this was understood, but laughable in terms of todays technology. And yes, the name DOES matter; it isn't generic quite yet.

As for plasma containment fields, you've completely missed the wrong end of the wrong point; the trick isn't keeping the plasma hot on the inside and cool on the outside, the trick is keeping the plasma still while you wave it like a willy nilly.

Given theoretical concerns based on the ideal gas laws (which plasma, as a non-degenerate state of matter very similar to gas, fits quite readily), there is no method by which a magnetic or even color induction field technology would EVER be a plausible method of containing plasma for melee based combat in the most ideal environment, let alone one with such a thick atmosphere, destabalizing the plasma current and rendering the power source unreasonably large.

That isn't to say we couldn't power the damn thing, only that any such device would be infinitely more useful as any of the MYRIAD of far more effective weapons possible: efficiency rates on even the best theoretical magnetic shielding are FAR below the yield of even the least efficient laser, which is ORDERS OF MAGNITUDE below even the least efficient mass driver.

tl;dr? While you are wasting energy running your plasma sword, the military will be using the orders of magnitude higher efficiencies of a coil gun to ram tau particles at 99.98 percent light speed into you.

And yes, that is actually an accurate assessment, given standard knowledge about tau particle mass, the max efficiencies of electromagnetic bubble design, and thermal inefficiencies associated with plasma.

Well excuse me. I just saw a special on the History Channel of the "Science of Star Wars". Some scientists said a "Light Saber" is impossible as "light/laser" can not be contained as a Star Wars Light Saber is depicted. It is impossible. So the only way to make a "Light Saber" is with plasma they said. I also never argued for the practicality of it. I just said that it will be possible some day in the future.

I also said I want a Holo Deck from Star Trek so I can rent that shit out to millionaires for billions of dollars. What the fuck would I do with a Light Saber? Having one would get a person arrested very quickly. The only thing it is good for is killing people.

[MorganL4]

either the point of view gun or the genesis device, probably the genesis device, cuz then I could create Earth 2, so that my grandchildren will have a place to live.

or there is that jewel from the never ending story where you get to make infinite wishes, and they all come true. ( sure its fantasy and not sci fi, but still.....)
