Some of my most memorable times was working with George Freibott of Priest River. North of town off of Highway 57 he had a private facility where we would research and build devices inspired by proteges of Tesla. The Otis t Carr OTC-X1 Utron accumulator was the most exciting of them all. Our first field test of the Utron accumulator almost destroyed the metal workbench bolted to the cement floor. We had similar issues with mercury leakage that plagued Carr as well.
