Copper Spiral Antenna Arrays: Atmospheric Charge Capture

Ground voltage measurements under 3-turn copper spirals compared to open-field control positions. Continuous monitoring across a 6-week spring period in raised bed conditions.

Key Findings
  • Measurable voltage differential observed beneath spiral antennas vs open control
  • Differential strongest during fair-weather afternoons (Carnegie peak correlation)
  • No significant effect observed during storm or overcast periods

High-Voltage DC Stimulation of Tomato Root Zones

24V DC applied 6cm below root crown across an 8-week grow cycle in raised beds. Compared yield, fruit Brix, and biomass against untreated control beds under identical irrigation and nutrition conditions.

Key Findings
  • 34% yield increase vs untreated control beds
  • Brix improvement of +1.8° (sweetness/nutrient density)
  • Root biomass increase observed at harvest in treated plots

Copper vs. Galvanized L-Coils & Spiral Antennas: A Basement Tray Comparison

Six-cell microgreens tray comparing copper and galvanized-steel L-coils against a center control, with a spiral-antenna arm tested alongside. An informal, single-run home trial — not a replicated study.

Key Findings
  • Copper L-coil outperformed the untreated control (visual comparison only)
  • Galvanized-steel L-coil outperformed the copper L-coil in the bottom-placement arm
  • Spiral-antenna (Ighina) arm matched the control
