• Obtaining Energy by the Annihilation of an Electron with a Positron

  Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished). In 2008, about 19% of global final energy consumption came from renewables, with 13% coming from traditional biomass, which is mainly used for heating, and 3.2% from hydroelectricity. New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 2.7% and are growing very rapidly. The share of renewables in electricity generation is around 18%, with 15% of global electricity coming from hydroelectricity and 3% from new renewables. This paper aims to disseminate new methods of obtaining energy. After 1950, began to appear nuclear fission plants. The fission energy was a necessary evil. In this mode it stretched the oil life, avoiding an energy crisis. Even so, the energy obtained from oil represents about 66% of all energy used. At this rate of use of oil, it will be consumed in about 40 years. Today, the production of energy obtained by nuclear fusion is not yet perfect prepared. But time passes quickly. We must rush to implement of the additional sources of energy already known, but and find new energy sources. In these circumstances this paper comes to proposing possible new energy sources, like energies obtained by the annihilation of a particle with its antiparticle. Getting energy, renewable, clean, friendly (not dangerous), cheaper, by annihilation (For example, the annihilation of an electron with an anti electron). Electron and positron are obtained by extracting them from atoms; the extraction, consume a negligible amount of energy. Then, the two particles are brought near one another (collision); now it occur the phenomenon of annihilation, when the rest mass is converted totally into energy (gamma photons). How much energy, can we get from inside of the matter? Einstein has showed that from one kg of matter we could get the energy needs for entire Earth for a year. We could do this, but only if we could extract all the energy from inside the matter. Through nuclear fusion reaction can be extracted only a part of the rest energy of the particles used. This drop of energy (1 / 1000 of the mass energy of a proton-neutron pairs) is called, discrepancy. For a kg of particles proton-neutron pairs, fusion energy is about a thousand times smaller than the total energy of a kilogram of matter (only 29 [GWh] from the total internal energy, 25 [TWh]); and considering that a return of 100% fusion reaction, which can’t be done anyway. Theoretically speaking, we can’t draw from within the matter (through nuclear fusion reaction) than at most the thousandth part of its energy. Having in view the yield of the nuclear fusion reaction, this obtained energy is and less. Through reaction of nuclear fission, the energies obtained will be even smaller. The solution proposed in this work, obtaining energy by the mutual annihilation of two opposite particles, makes possible the requirement of extracting whole energy contained in matter. A pair formed by a particle and its antiparticle, are brought side by side, at a distance which allow the process of reciprocal annihilation. To increase the yield of the annihilation reaction (the number of annihilated particles from all particles that exist), we can accelerate the particles and antiparticles separately, and then we may send them into a room where they encounter annihilation at speeds and energies high, or at velocities and energies very high. If we use electrons and positrons for the reaction of annihilation, it results photons of the gamma type. In this case, to prevent the possible decay of the obtained photons, again into electrons and positrons (for beginning of this annihilation process with success), the antiparticles and particles used in the process of annihilation, should be collided at low speeds and with low energy. We can test then the optimum energy particle which permits the reaction with the maxim yield. It is necessary that most particles and antiparticles used, to meet and annihilate each other, and it should be stable as many of the obtained gamma particles.
