...wait, so we dont get to see one that you built?

[Docjazz11]

Doc:well yours might need 15 megawatts but at least you dont need 1.21 GIGAWATTS to power a time machine(still stuck in 1955)

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

[BushmasterGuy77]

Instead of seeing a lightsaber at the end, I got to see a bunch of virgins.

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

[TheMonkey747]

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.

@ 7:21 The devil is clearly unhappy that he will have to wait 50 years before he can have his own lightsaber.

'What is a guy like me to do?!'

[PassionateShadow]

what's keeping the magnet from melting?

[lmaolongtime1120]

7:21 WTF.

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.

[hurmpfff]

i like how this design uses normal air pulled in from the bottom.

[hurmpfff]

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.
