20160049839 | DEVICE AND PROCESS FOR THE GENERATION OF ELECTRICAL ENERGY - A muonic electromagnetic generator for generating electrical energy is provided and includes a generator that is connectable to at least one source of electric energy with a lower power than the power generated by the generator. The generator includes at least one outer electric coil, at least one inner electric coil, situated substantially inside the outer electric coil, and an oscillator. The oscillator is connected between the source of electrical energy and the outer electric coil. When the outer electric coil is connected to a source of electric energy via an oscillator that was previously tuned to emit a frequency corresponding to a certain fraction specific to the Compton frequency of a muon, the muonic energy is absorbed by an inner electric coil, and this energy can be used to feed any external load. This muonic energy can be significantly greater than the power of the source of energy | 02-18-2016 |
