As water falls even through cold air, at a water fall, it heats up by 20° C. It forms O3, helium and gives off gamma wave radiation. The importance of the latter is the he is a sign of nuclear processes. We are talking about high mountain river water. As pure as you can get. It has no background count.
Yes that if you fall of more than 10 feet, is converted into helium and oxygen. This O reacts with O2 from the air to form O3. If the H2O just got broken apart it would reform. No gamma rays, no helium. There is no volcanic vents which is only source of helium outside of nuclear fusion. We are doing molecular nuclear fusion.
At around 10 to 0° C. This is why the water heats up, and falls give out nuclear radiation. A water fall does what CERN cannot. We get the same process in the countryside, with breaking waves and rain stops. It is the driving force for lightening –the seas are most energetic Energy System on earth.
