Brown believed that his large, high voltage, high capacity capacitors produced an electric field strong enough to marginally interact with the Earth's gravitational pull, a phenomenon he labeled electrogravitics. Several researchers claim that conventional physics cannot adequately explain the phenomenon. The effect has become something of a cause célèbre in the UFO community, where it is seen as an example of something much more exotic than electrokinetics. William L. Moore and Charles Berlitz devoted an entire chapter of their book on the " Philadelphia Experiment " to a retelling of Brown's early work with the effect, implying he had discovered a new electrogravity effect and that it was being used by UFOs. Today, the Internet is filled with sites devoted to this interpretation of the effect.
