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”:
These six magnets are arranged in a hexagon and wired as shown here:
And the schematic diagram is:
One extremely interesting feature of this passive device is that it has been witnessed producing 450 mV for several hours; it was capable of developing up to 12 Volts. The witnesses were quite sure that it was not picking up radio or mains input. So, what was it picking up? With magnets as the key component, it seems clear that it is the zero-point energy field which is being accessed, but clearly, the access represents a vanishingly small percentage of the actual power available
To operate the device, the switch is left in the open position, the magnets are moved slightly apart and the sliding coil set into various positions with a wait of several minutes between adjustments. The magnets are then separated still further and the coils moved again. This process is repeated until at a critical separation of the magnets, a voltage is developed. The switch is now closed and the process continued more slowly. The voltage then builds up to a maximum which is then maintained indefinitely. The position of the apparatus in the room and the orientation of the device had no effect on the output.
The magnets were selected to be as nearly equal in strength as possible and the resistance of the magnet and coil were checked after winding to make sure they were as nearly equal as possible (about 0.33 ohms).
As far as I am aware, nobody has managed to produce a successful replication of either of the Hans Coler devices, which is a pity since it seems clear that these devices have the potential to indicate the nature of the zero-point energy field and possibly, how it may be tapped efficiently.
A very neat construction of the Coler ‘Magnetstromapparat’ by an unknown German experimenter is shown below - I’m afraid without permission as I have no idea who he is or how to contact him to ask his permission. The quality of workmanship is impressive and the result is a very professional looking device. Notice the sliding coil arrangement at the bottom left with one coil being positioned closely inside another and held in place where the experimenter chooses:
