text: The Patterson power cell is an electrolysis device invented by chemist James A. Patterson, which he said created 200 times more energy than it used, and neutralizes radioactivity without emitting any harmful radiation. It is one of several cells that some observers classified as cold fusion; cells which were the subject of an intense scientific controversy in 1989, before being discredited in the eyes of mainstream science.
  The Patterson power cell is given little credence by scientists. Physicist Robert L. Park describes the device as fringe science in his book Voodoo Science.
