Claims: Radiant_One_Youtube

Source gap: the project holds one image only, a schematic screenshot (Earth-energy-extra-schematic.png) from the YouTube channel radiant_one. There is no video, transcript, measurements, text explanation or author identity. OCR was partial and garbled; component values below were read from the image itself [read: page image p.1]. To assess the claims, obtain the video(s) of the channel (the circuit "GndNrgEx 1.1"), any build notes, and recorded input/output power measurements. Any conclusion on the claims beyond circuit analysis rests on [memory] or the title alone.

Central claims (implied by the schematic's title and notes; the author states no claim text):

1. A circuit named "Ground Energy Extraction" can draw usable electrical energy from the earth through an earth rod.
2. A MPSA06 transistor RF oscillator (L1 8.6 uH, Lb 1.4 uH, C1 470 pF, 1 Meg bias, 11-13 V supply) coupled by L2 (26.7 uH) can drive an earth-rod-connected load of two 26-LED series strings, with two 1N4148 diodes in parallel (same direction, anode at L2, cathode at the earth rod) across the whole group.
3. The supply current drawn with the earth rod connected can be tuned (by moving an alligator clip near L2) to equal the current drawn without it ("unearthed" = "earthed"), which the author presents as the tuned operating condition.
4. The circuit produces enough RF that standard meters and oscilloscopes can be damaged or read incorrectly, so ordinary measurements may be unreliable.
5. Author's reported figures (second-hand, from YouTube descriptions/transcripts via the Investigator; no video watched): 30 mA supply current (GndNrgEx_3, 2015, supply type unstated) and "each led is only drawing 4mW from a battery" (GndNrgEx_9, 2016). The 4 mW is most naturally battery input per LED (about 208 mW total, about 17 mA at 12 V) but may be measured LED output; no LED output measurement is confirmed, and the two figures are from different videos.
