Safety & Liability Disclaimer
Replicating alternative electromagnetism or mechanical resonance systems carries extreme physical hazards including lethal voltage shock, explosive gas ignition, mechanical shrapnel, and chemical toxicity. All contents, schematics, and guidelines on this page are provided strictly for educational and historical research.
Device-Specific Hazards:
LETHAL. Extremely dangerous high-voltage circuits. The CSET tube technology is poorly understood.

Overview
An electric engine using pulsed high-voltage capacitor discharges through a specialized Conversion Switching Element Tube (CSET) to drive electromagnets. Peter Lindemann's analysis identifies this as 'splitting the positive' — the process of shocking high-voltage capacitors to release 'cold electricity' that performs work without conventional heat losses.
⚖️ What Would Convince Us?
To validate the anomalies claimed for this device under mainstream scientific parameters, builders and inventors must document and present evidence satisfying the following criteria:
Verification of CSET tube conversion efficiency
Continuous closed-loop self-rotation
Calorimetric output measurement of electromagnets
Investigation & Credibility Metrics
Direct inventor writings, patents, or lab notebooks available.
Claimed overunity/propulsion has not been verified in a control lab.
Multiple builders completed attempts and reported zero success.
Simple multimeters used. Subject to power-factor or ground-loop errors.
This device is purely open-source or historical; no active sales.
Community Status
Multiple US patents provide documentation. Peter Lindemann's analysis ('The Free Energy Secrets of Cold Electricity') is foundational literature. The original CSET tubes no longer exist; replicators substitute ignitrons, thyratrons, or spark gaps.

Research & Engineering Notice
US Patents provide schematics of the CSET tube and spark commutation grids, but no detailed mechanical assembly guides for the rotary engine housing survive.
