Hydrogen should be produce on earth meanwhile it consumed on the Sun; it is very highlighting Idea that I had been engaged with it during last years. About 75 percent of Sun's mass consists of Hydrogen. As we know the Source of energy on the Sun is Nuclear Fusion.
The energy produced by nuclear reactions in the interior of the Sun must equal the amount of energy radiated from the surface, since otherwise the Sun could not have been structurally stable over long periods of time. Evidence for the stability of the Sun comes from several sources. Stability over a period of nearly 3*10E9 years is implied by the relative stability of the temperature at the Earth’s surface (oxidized sediments and fossil remains indicate that water in its fluid phase has been present throughout such periods).
Stability over an even longer time is implicit in our understanding of the evolution of the Sun and other similar stars.
The conversion of energy contained in the atomic constituents of main sequence stars such as the Sun from heat of nuclear reactions which transforms hydrogen into helium) to radiation escaping from the surface is largely understood.
At present the Sun radiates energy at the rate of 3.9*10E26 W. At the top of the Earth’s atmosphere an average power of 1353 WmE-2 is passing through a plane perpendicular to the direction of the Sun. The average distance of the Earth from the Sun is 1.5*10E11 m.
