1957: Otis T. Carr announces circular foil spacecraft
In 1957, inventor Otis T. Carr publicly revealed his design for a round spacecraft operating in a fourth spatial dimension, driven by a device called Utron Electric Accumulator that harnesses universal free energy.
Background
Announcement
In 1957, Otis T. Carr made public his invention of a circular spacecraft said to operate in a fourth dimension. The craft used a Utron Electric Accumulator as its drive, which drew free energy from the universe without requiring an external power source.
Technical Details
The system was based on counter-rotating parts: an inner rotor with batteries and neutron coils turning against an outer ring with electromagnets. With precise synchronisation, gravity was supposedly neutralised and energy drawn from spatial fields. Carr described it as a weightlessness effect produced by tensor stresses. Models were tested and patents filed.
Significance
The claim drew on ideas of Nikola Tesla and promised revolutionary energy independence. Although no independent evidence exists, it attracted attention in UFO and free-energy circles. Later demonstrations failed and Carr became embroiled in disputes. No witnesses to the announcement are specified; sources cite Clark.
