Project Winterhaven was a proposal drawn up in 1952–1953 by the Townsend Brown Foundation for a joint U.S. military research contract to investigate a claimed link between electrical and gravitational fields, as proposed by physicist Thomas Townsend Brown, and to develop it for aircraft propulsion and communications. It was never funded.[1][2]

Brown was born on 11 March 1905 in Zanesville, Ohio. From the 1920s he claimed that highly charged capacitors experienced a thrust that might be linked to gravity, an effect he called "electrogravitics", and he patented an electrostatic motor. He worked at the Naval Research Laboratory from 1930 to 1933, held Navy posts during the Second World War and later worked as a radar consultant. His foundation was a non-profit Ohio corporation founded in 1938.[1][2]

The proposal, "A Proposal for Joint Services Research and Development Contract", revised on 1 January 1953, aimed to compile evidence and run experiments to confirm or deny a link between electrodynamic and gravitational fields. It envisaged a prime contractor approved by the Department of Defense distributing funds to four companies and four academic institutions, split between propulsion and communications. Participants proposed included the Franklin Institute in Philadelphia, which sent Brown a cover letter on 10 December 1952 asking for a $5,000 preliminary grant, as well as the Stanford Research Institute, the National Bureau of Standards and the University of Chicago.[1]

Claims

The proposal said a 2-foot charged disc "airfoil" at 50,000 volts had reached about 17 feet per second, and planned larger discs of 4 and 10 feet; it estimated that large flying discs at 5 million volts might reach about 1,150 mph, and more at high altitude. It also claimed a communication system had sent signals through steel and concrete, and proposed detecting distant atomic explosions. The proposal itself admitted that the thrust potential remained highly theoretical.[1]

Assessment

Navy and other evaluators who examined Brown's devices concluded that their movement came from "ion wind" — air pushed by electrical discharge — rather than any new force, and Winterhaven was never funded. Brown continued his work in France in the mid-1950s. Supporters, including author Nick Cook in The Hunt for Zero Point, argue that electrogravitics went into classified aerospace research; mainstream physicists say there is no evidence the effect works in a vacuum.[2][3]
