Title: Hydrogen & Geothermics
All geothermal activities involve water, which is splitted into hydrogen and oxygen. This is the reason that all geothermal activities result with hydrogen soaked water or water vapor. The splitting of water occurs due to electrolysis, the electrical current for which stems from magnetic rocks. Water passing through a magnetic fields forms electrical current. This explains the facts that hot springs have been flowing for thousands of years. The water is reducing and the source of energy is inexhaustible.
The water of hot springs and geysers is strongly reducing measuring a negative redox potential. Steam emanating from the ground is very reducing. The smell of sulfur in hot spring is the result of reduction of sulfates to hydrogen sulfide. Oxidation of the sulfide in the air oxidizes it to sulfur.
Hot springs flow for thousands of years and its source is a few meters from the surface, geysers are deeper and burst when the temperature is above 100 C. The force pushing the water out is the high vapor pressure.
The source of the heat is by ohmic heating formed by current passing through resistance. At large depth of hundreds of meters the process continuous, reaching high temperature that melts the rocks, forming extremely high vapor pressure that causes the eruption of lava and steam.
Accumulation of hydrogen and oxygen in voids underground would cause an explosion upon recombination of hydrogen and oxygen to form water. Actually it has been discovered that hydrogen gas is emanating along faults. Learning more about the formation of underground electrical currents would enable to imitate nature and form low cost energy.
