Understanding Radiant Displacement Current (RDC)

---

RDC uses displacement current – a changing electric field – from quick high-voltage pulses in a conversion tube. This turns regular DC into "cold" electricity: efficient, low heat, no shock. Tube (tungsten rods, copper meshes) gets 3kV pulses (>500 V/ns rise, 3ns width), making displacement dominant (ratio 2.95e12). Efficiency: η = η_t / (1 - r η_t), r=0.27. Applications: Wireless transfer, cold plasma, fusion aid, propulsion. Differs from steady DC: transients vs. constant flow (cold/efficient vs. hot/lossy).

Edwin Gray's conversion tube: High-voltage (3kV) pulses applied to tungsten high anode, low-voltage pulses to low anode, with copper mesh grids capturing output. Rapid dV/dt (>500 V/ns, 3ns width) creates displacement current dominance, converting conduction to "cold" electricity for efficient load powering and recovery.
