This is a followup on my electrostatic gravity energy storage concept, when I wondered if AC could be stored in the same manner as DC. It did not pan out, but I determined that three-phase AC would provide enough voltage for sustentation on 2 of the 3 phases at any given time. So coupling 2 three-phase cables with 6 active columns results in a stable platform. The passive columns take the weight of the structure when the system is switched off. They also keep the turns of the spiral columns from touching when compressed, allowing for electrostatic repulsion from the start.
