This document provides a summary of a wiki article about theories of extracting free energy from the electric field. It discusses several inventors and researchers who developed systems tapping into this energy, including John Bedini, Edwin Gray, and Stanley Meyer. The document puts forward a unified theory to explain how these different systems all operate on the same principle of utilizing the electric field without violating the laws of physics. It aims to bring together relevant information scattered across forums to help further develop this technology through an open source approach.
