Not if you're looking for an actual "light" saber.
But a heated plasma held by shaped magnetic field might fit the bill.
Oh, except for the power supply.
Squirting lighter fluid doesn't cut it though.
May I suggest a CLEAR (i.e. see-through tube)
of REALLY TOUGH Alumina Oxide ceramic glass
which has micro-sized holes drilled into it.
It basically become a clear Venturi Tube:
which can then EXPEL high pressure propane
(or Hydrogen!) hidden in the handle. With a titanium
mini-tank I could probably get up to 2000 psi which should
give me a about 27 minutes of burning power normal
2000 PSI propane tank pressures.
You could go much higher pressures but 2000 PSI
is still relatively safe enough to be contained
by a titanium miniature pressure vessel.
The tiny tubes in the Alumina Tube would create
a BLUE FLAME on the exterior and the extreme
pressure differential would probably create an
ICE-FOG effect too as the gas expanded and
cooled the surrounding area.
The Alumina Oxide Ceramic tib would be both
CLEAR and TOUGH ENOUGH you actually COULD
use it for a REAL lightsaber battle with the full-on
blue glow effect. You just have to make sure
the holes in the tube are shaped and set at a
specific configuration and diameter so that
mixing of the Propane or Hydrogen with
normal air and occurs in a normal and
At 2000 PSI, the pressure would allow
for various "Blue Lightsaber Glow" configurations
since you could create angled holes, V-shaped
holes, Inverted conical holes or other shapes
so that the buring gas comes out at
specific velocities and outward spread!
If you use TWO miniature tanks with Oxy-Acetylene then
you could get your temperatures up to 3500 degrees
Celcius or (6332 Degrees Fahrenheit!) for some
REAL cutting power!
SOME VERY GENERAL BURNING POWER MATH:
20 lbs Barbecue Tank of propane holds about
4 gallons (15.1416 litres) and 366,000 BTUs
which would give you 22 hours for a small
10,000 btu burner.
So one Lightsaber powered by propane at
500 CC or 0.5 Litre hidden in handle is about
0.13 Gallons at normal tank pressures 300 PSI
So 10,000 BTU is 4 minutes of burning time.
At 2000 PSI it's about 27 minutes of burning time
since we can hold MUCH MORE gas!
