, a Georgian inventor who, in the early 2000s, demonstrated a device that appeared to produce significant electrical output from a mysterious, self-sustaining source.

Plausible as a resonant circuit, but not verified as over-unity. The "water capacitor" does nothing a standard capacitor cannot. No peer-reviewed paper has confirmed net energy gain.

The keyword “verified” is the most dangerous part of this search. In science, verification requires:

While many hobbyists have "verified" that the circuits work as high-voltage oscillators, no one has publicly and scientifically verified a self-sustaining unit that produces a net gain in power.

One of the most famous attempts to verify Kapanadze’s work was by French researcher Jean-Louis Naudin. His "Kapagen" (Kapanadze Generator) schematics are the most common "verified" versions found online.

Tariel Kapanadze is an inventor from the Republic of Georgia who rose to prominence in the early 2000s. He claimed to have discovered a method to harness energy from the environment—often described as "ambient energy" or the "aether"—to produce a self-sustaining electrical output.
