Hydrogen is the best friend of man and the environment. Actually, it is the core element from that can extract energy, at infinity, in various forms. Until now has not been sufficiently exploited, but once with the evolution of the human species is the time to start to pool all types of energy which the hydrogen and its isotopes may donate them to us. Obviously the most abundant are nuclear energies which may be extracted from the hydrogen, either by well-known reaction of fission or through the much-desired fusion. In the reaction of a merger Deuterium-Tritium, for example, the energy required to overcome the Coulomb barrier is 0.1 MeV. Conversion between the energy and the temperature shows that the barrier of 0.1 MeV would be exceeded at a temperature of over 1.2 billion Kelvin degrees. According to the static calculations required a temperature of fusion to warm temperature is about 4 billion degrees. There is already an increase of almost four times than the latest calculations indicated by specialists. But calculating using radius determined dynamically, when the energy required is much higher, we come to a temperature necessary for the attainment of the thermonuclear fusion reaction of 40 trillion degrees, as for any 1 keV is needed about 10 million degrees temperature. Hot temperatures the merger being elusive, scientists have thought of achieving cold fusion.
