How to make a Stable Plasmoid ( Ball Lightning ) with the GMR

"The GMR v 1.0 is a microwave resonator composed with a small quater wave antenna mounted on an artificial ground surface. The frequency of the magnetron is 2.45 GHz, its wave length is l = 12.2 cm, this gives the height of the 1/4 wave microwave antenna : l/4 = 3 cm and the ground base diameter : l/2 = 6 cm."

I'm not usually one to quibble but I'm looking at their calculations and I've just got to say, they actually think this Plasmoid is gonna be stable??? HA!!!
