I saw that, you would need a Plasma Cutter sized unit on a wagon behind you to power it, but plasma is just the 4th state of matter. Not really hard to achieve, just hard to maintain because of the energy requirements 440Volts, with around 200 amps would suffice. Now, what would happen when they both touched would depend on the polarity, and who had the stiffer Rod. The moisture content in the air would be an issue also, because the sabers would crack water into Hydrogen and Oxygen, so you would have "Brown's Gas" surrounding the both of you, and that stuff is extremely volatile. When it does explode, it returns back into it's molecular state, water.
