http://www.free-energy-info.co.uk/Chapt3.htmlProfessor Gennady Markov, General Director of STC "Virus" and author of many inventions and discoveries, received an international patent for a new a transformer design which he created. His work involves a new law in the field of physics and electrical engineering. He says: In 1831 Faraday discovered electromagnetic induction. Then his ideas were further developed by Maxwell. For more than 160 years following that, no one advanced fundamental electrodynamics by even a single step. Eight years ago, I applied for an international patent, valid in 20 countries, as I had created a transformer, which has already received four Russian patents. My discovery was made despite the "laws" of the great physicist Faraday who said that “magnetic fluxes in a magnetic circuit should be combined separately with the resulting combined flux moving in only one direction. Only then can you have a working transformer”.
I dared to do the opposite: take a coil with two identical windings and operate them towards each other. This creates equal magnetic fluxes, moving toward each other, which cancel each other out, but do not destroy each other as Faraday and Maxwell claimed. I determined a new law: ‘The Principle of Superimposition of Magnetic Fields in Ferromagnetic Materials’. The superimposition - is the addition of magnetic fields. The essence of the law is that the magnetic fields are added, cancel each other, but they are not destroyed. And here the important part is "they are not destroyed" and that is the key fact on which my law is based.
I wrote an article on this subject, which was published in the journal "Applied Physics". I demonstrated a transformer at an international exhibition in China, where it caused great interest among scientists and other experts. That transformer had excellent performance and in fact, it can raise or lower the voltage without any need for a secondary winding. My new law allows us, firstly, to create high-power transformers where the weight and size per unit of capacity is 20 to 30 times lower than in conventional Faraday transformers. Second, I created a transformer which, despite its large dimensions and power-handling capabilities, can operate at frequencies up to several megahertz (at the present time, a conventional transformer operates at frequencies of only 30 to 50 Hertz, and if you operate them at 100 Hz or higher, the metal overheats and the transformer breaks down). My transformer can operate safely at frequencies of millions of Hertz.
Conventional transformers tend to be very bulky because they contain a great deal of iron with the weight of a standard 4 MW transformer being 3670 Kg. My 4 MW transformer weighs a total of 370 kg. When constructing a new transformer you can use any quality of steel quality and there are virtually no restrictions on the frequency range in which it can operate. Unlike conventional transformers, a new transformer can be transported from the place of manufacture to the point of use quite easily. This new transformer design gives us a huge opportunity to create a new generation of technology.
Please note that the transformer does not operate at low frequencies. Its frequency range is 10 kHz to 40 MHz, and the voltage needs to be at least 40 volts. [/font]

The design measures 3.02 inches by 3.17 inches by 2.22 inches, and weighed 2.4 pounds. In tests, the transformer constructed according to state-of-the-art techniques, after 40 minutes, showed a windings temperature of 200 DEG C. at the center of the windings and suffered catastrophic failure due to excess heat (FIG. 2).
A duplicate transformer 10 weighing approximately 0.21 lb/kW was constructed utilizing the technology set forth in this invention with the K1100 conductive strips 16 placed within the windings 14 of the transformer. The design measured 3.02 inches by 3.17 inches by 2.22 inches and weighed 2.4 pounds. In tests, the transformer 10 with the thermally conductive strips 16 placed alternately between windings (FIG. 1) showed, after approximately 40 minutes, a windings 14 temperature of approximately 70 DEG C. without failure (FIG. 3).
This invention allows for the reduction in size of a high power transformers by a factor of 4 to 8 and a reduction in weight by a factor of 4 to 6, and an increase in power density by 5 to 10 in power. The efficiency of the transformer is improved by maximizing the heat transfer from the transformers interior and minimizing voltage breakdown. The thermal properties of each core 12 will dictate the quantity of the thermally conductive strip 16 material required to lower the transformer temperature to a predetermined level, some testing may be required to established the optimal amount needed to provide proper cooling.
