The Devices of Hans Coler.A German naval captain called Hans Coler invented a COP>1 generator in 1925. He called this device the ‘Stromerzeuger’ and for a few watts from a dry battery it provided 6 kW continuously. He was refused development support because it was “a perpetual motion machine”.Hans also invented a passive device which he called the ‘Magnetstromapparat’. His unit required very careful and slow adjustment to get it operating but when it started it continued on test in a locked room for three months of continuous operation. Nobody, including Hans, seems any too sure how this device works but it is presented here in case you wish to research it further. It comprises six bar magnets wound as shown here. Some are wound in a clockwise direction when looking at the North pole and these are called “Right” those wound in an anticlockwise direction are called "Left."
