• The "Patent" Suppression

  This theory claimed that a revolutionary "fuel-less" engine had been invented in the late nineteenth century and then quietly purchased, hidden, or destroyed by entrenched coal and industrial interests. The most important historical anchor for this story type is the Keely motor controversy, in which John Ernst Worrell Keely claimed to harness a new motive force variously described as vaporic, etheric, or vibratory. The record shows intense public fascination, investment, technical secrecy, and later exposure, but no verified suppressed engine that operated without fuel in the ordinary sense.
