Obtaining Energy by the Annihilation of an Electron with a Positron. We can extract the energy of the rest mass of an electron. For a pair of an electron and a positron this energy is circa 1 MeV. The particles must to be collided, after they are being accelerated to an optimal energy level. All the energies are collected at the exit of the Synchrotrons, after the collision of the opposite particles. We will recover the accelerating energy, and in addition we also collect the rest energy of the electrons and positrons.LEGGI IL BLOG
