okay, how many Star Wars nerds do we have here? i'm thinking about the possibility of a lightsaber. given there are several major hurtles that we'd need to get through but i'm just trying to sort this out. a) i've realized it could not be a 'light' saber. the photons could not spontaniously stop. a plasma saber is what i've decided on. problems with plasma saber: *******needs LOTS of power in small area. could only be 'activated' 2-3 times before depletion. possible solution: once activated plasma could be stored in magnetic bottle until ejection. (note: this uses power to maintain but is less than heating a gas to a plasma temperature everytime) *******needs a way to control extreme heat (possible solution to the latter: use an extremely low grade plasmas...like 1000-2000 degrees F b) it would have to be emitted in a fountain-like path. emitted from the inside and somehow pulled back in by magnetic coils. (remember this is an ionized gas so it would be easy to control its movements.) feedback? ideas? constructive critisism?
