I envision a control knob like on my old train set transformer. Turn up the juice for higher output and faster speed. Is that all there is to do to reach unity now? That would be lucky…What are the mechanisms of control to optimize the formation of the plasmoid aside from gas pressure, positioning of the cathodes to the anode and increasing current? I’m wondering about how the filaments interact with the gas. Apart from increased pressure of the gas increasing density. The density is homogeneous, would there be any benefit to imparting motion to the gas medium as you do with the angular momentum to the magnetic field? A swirling vortex of gas would mimic galaxy/solar system formation, would that apply to a DPF? The circulation also might aid in cooling, or would this make everything unstable?
