Helium is being produced on Earth
Engineers doing nuclear fusion Since the atmosphere of the Earth has a mass of about 5.14×1018 kilograms (1.133×1019 lb), the mass of ³He in the Earth's atmosphere is the product of these numbers, or about 37,000 tonnes (36,000 long tons; 41,000 short tons) of ³He. Helium is a light gas. And is not contained by the as feeble gravity. Being lost to space within 24 hours. However nature is busy making helium all day. The biggest source of helium is the turbulence in the deep seas. Where the cold currents taking equatorial, water to the equator to figure heat, to physical molecular nuclear fusion. 1 H₂O+P+TU→³He+O+E²+X-ray we know there he is nuclear fusion going on, as we bubble of helium three. Which no longer the production of X rays, tells us we are doing nuclear processes. And there is no source of radioactive decay! We are doing nuclear fusion from the turbulent flow of high pressure water. And we can sample for the gas bubbles...
