Hessdalen 'Natural Battery' / Piezoelectric Hypothesis.
hypothesisgovernment_studyScientific Instrumentation & Sensor Data
Geophysical power-source models. Piezoelectric: quartz under tectonic stress generates charge (amplified by Fe/Cu) — likely too weak. Battery (Monari 2014; Monari & Montebugnoli): valley as a giant cell — mineral-rich slopes (S, Cu, Zn) as electrodes, the Hesja river as electrolyte. Critics note energy-budget and central-geometry gaps.
