When the name Hans Coler is mentioned, those that are familiar with the German saucer of World War II and before, think of futuristic engines, engines that might be able to power a device, such as a flying saucer, into space. Some say that one of the engines that Coler invented ran on a small battery but could put our thousand of watts of unlimited power. By unlimited I mean power that would never run out. When he was captured at the end of the war, instead of being treated like a fraud, he was questioned at length. Did he try and hide his inventions from the conquering army? No just the reverse. He not only began to reveal everything but offered to build an engine. This was his "Magnetstromapparat" engine. While it can not be proved with certainty, the story goes on to state that he did build an engine that could obtain as high as 60 millivolts.
The questioning didn't stop with Hans Coler. An associate of his who was also a financial backer was also interrogated. Dr. F. Modersohn was questioned about every detail of Coler's engines and his testimony matched that of Coler. One odd fact about these engines was the fact that neither Coler or Modersohn was able to cite any scientific principle to justify the so called performance of these engines.
Apparently Coler had been working on these engines for some time. A small model had already been built in 1925 and it was said that it was shown to Professor Kloss. It was said that Kloss was so impressed that he wanted the government to review it. A patent was applied for and denied as was the request for government review. I guess it just sounded too much like a hoax since by its basic premise, unlimited operation, it was against all known physical laws. It is also said that by 1933 many other scientists had seen this engine and a 70 watt model that had been build with the help of another scientist.
Things were getting serious after the war started. A much larger version of the engine had been built that put out 6 kilowatts. Dr. H Frolich was sent to work with Coler. The project was now under the purview of the Research Department of O.K.M. Frolich's specialty was the induction circuits which he studied. When the war ended Frolich was taken to the Soviet Union. Supposedly a bomb destroyed the building housing Coler's work in 1945. The materials used seemed to be very simple, nothing was exotic as one might think.
After an engine was constructed by Coler, it is stated that by manual adjustment he was able to increase tension as high as 60 millivolts. This was done by trial and error, by moving the magnets slightly further apart. The parts of this engine were described by Dr. Kloss as being two rows of copper plates, two rows of flat spools and some electro magnets. One must admit that the parts list seems rather simplistic. I mean, after all, was this these the parts for the supposed German UFO engine? You have to wonder how this could be possible. Coler explained that the magnetic current oscillated at a certain frequency causing the gain in power and that he had only found this out by experimenting and could give no scientific explanation for it. It was stated that the amount of energy in the circuit was much greater than the energy taken from the batteries. If this were true than this would be only one of two devices that I know of that produce more energy than they consume. The other being certain breeder reactors that produce more fuel than they use.
The British Government madea report on Coler available to the public. It was released by the U.K. Department of Scientific and Industrial Research, National Lending Library for Science and Technology. The author of the report is named as R. Hurst, Ministry of Supply. Here are some parts of it:
This device consists of six permanent magnets wound in a special way so that the circuit includes the magnet itself as well as the winding. (See Fig. 1).
These six magnet-coils are arranged in a hexagon and connected as shown in the diagram (Figs. 2 and 3), in a circuit which includes two small condensers, a switch and a pair of solenoidal coils, one sliding inside the other. To bring the device into operation the switch is left open, 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, an indication appears on the voltmeter. The switch is now closed and the procedure continued more slowly. The tension then builds up gradually to a maximum, and should then remain indefinitely. The greatest tension obtained was stated to be 12 volts.
The 'Magnetostromapparat' was developed by Coler and von Unruh (now dead) early in 1933, and they were later assisted by Franz Haid of Siemens-Schukert, who built himself a model which worked in December 1933. This was seen by Dr. Kurt Mie of Berlin Technische Hochschule and Herr Fehr (Haber's assistant at K.W.I.), who reported that the device apparently worked and that they could detect no fraud. One model is said to have worked for 3 months locked in a room in the Norwegian Legation in Berlin in 1933. No further work appears to have been done on this system since that date.
2. The 'Stromerzeuger'
On July 1, 1946 experiments were being continued after three days of fruitless adjusting, and when the magnets were at a separation of about 7 mm the first small deflection was noted (about 9 a.m.). The switch was closed and, by slow adjustment of the sliding coil and by increasing the separation of the magnets to just over 8 mm, by 11 a.m., the tension was raised to 250 millivolts and by 12.30 p.m. it was 450 millivolts. This was maintained for another 3 hours, when a soldered tag became disconnected, and the meter slowly dropped back to zero. Soldering up the broken connection did not restore the tension. The magnets were closed up and left overnight and the same procedure for finding the adjustment was repeated on July 2, 1946. After about three hours a deflection of 60 millivolt was obtained; this was maintained for more than 30 minutes, but then decreased to zero when further adjustments were tried.
During all this work the model was completely open, and nothing could be hidden in it. The breadboard and meter could be picked up and moved round the room, tilted, or turned, without effect.
The apparatus would appear to be too crude to act as an a receiver of broadcast energy, or to operate by induction from the mains (the nearest cable being at least 6 feet away), and the result must for the moment be regarded as inexplicable.
