An overview of Searl Effect Generator design, construction, and theory by John Searl. The Searl Effect Generator is claimed to produce zero-point energy and function as a prime-mover for energy-generation & advanced propulsion applications, and is constructed as a series of rollers inside concentric rings that rotate rapidly during operation.

John Searl describes the process of designing rollers for the Searl Effect Generator, and how those rollers are mounted in concentric rings to produce a form of rotary motion when an AC electric signal is applied.

According to Searl, the Searl Effect Generator immediately spins up to peak operating frequency, producing vast amounts of electric energy in excess of the input current.
