Electrogravitics is a purported method of creating anti-gravity or unconventional effects through the use of electric fields on objects. It has been linked to gravity and has been described as both a free energy machine and a propulsion source with reported efficiency of a “million to one”. Its history dates back to the 1950s when researcher Thomas Townsend Brown developed 3-foot platforms that could hover and rotate using high voltage electric fields. The book "Electrogravitics Systems" focuses on the scientific concepts and theories behind this technology, while a companion volume explores the possibility of using electrogravitics for propulsion and other technological advances with assistance from AI.
