Edwin Gray
Biography
Edwin V. Gray Sr. was an American inventor who developed the EMA (Electromagnetic Association) motor in the 1970s. His technology used high-voltage capacitor discharges through a specialized Conversion Switching Element Tube (CSET) to power electromagnets with what he described as "cold electricity" — energy that performed mechanical work without generating conventional resistive heat. Peter Lindemann's analysis identifies Gray's process as "splitting the positive," a technique for shocking capacitors to release radiant energy. Gray held multiple US patents but his technology was never successfully commercialized, and the original CSET tubes no longer exist.
