VIC design session v92: best candidate (Q=1.2, 12.9kHz)
Sweep: Force the 1.37nF (1-2 cell) case: sweep per-choke L 3.7-9mH to land f_r across the untested 32-50kHz compliant band, with high-turn AWG18-22 coils to hold coil Q high while I chase Td, not Q.
Cell: 8mm rod in 9.0mm tube × 40mm, 8 cell(s) parallel → C_eff = 20.53nF, bulk water R = 1203Ω. Water/electrodes (Randles): 2ppm Na+ @ 25°C, surface ×1 → λ_D 53nm, C_dl 55.8µF, cell series R 509.5Ω, displacement current 53.8%, breakdown margin ×213. Vapor-film discharge (CGDE onset, 140V across 0.1mm film): regime constants-out-of-range, film Paschen 719V, 56 Td. Per-molecule (series micro-capacitor chain): 1.85M molecules across 0.50mm → 75.76 µV/molecule (polarization (µV band)). Chokes: 2 × 0.0037H (800 turns, AWG 18, 96m wire, AC R 2.0Ω each). At resonance f_r = 12.91kHz: Xl = 600Ω, Xc = 600Ω, tank Q = 1.2, coil Q = 150.2. Cell voltage 140V from 120V drive (×1.2). Tank current 0.23A circulating (CW upper bound — rate wire/switch for this); average input 23mA at 10% duty. All constraints satisfied (current <1A, band, wire length). Score 0.273.
