on the energy page, the Marshall Hydrothermal Recovery System brings
massive quantites of hydrothermal fluid to the surface. Its temperature
is incredibly high, hot enough to melt lead, but it does not boil
because of the intense pressures at the depths where the vents are
located. The volumes noted show about 76,000,000 liters, or 20,000,000
gallons of fluid brought to the surface every hour. As it rises
through the insulated pipe structure and the ambient pressure decreases,
it will flash to steam, which can be distilled back into fresh water.
several additional stages of purification will likely be necessary,
the natural heat from the process itself provides the most important
part of the energy needed for the process. If only 50% of the total
volume could be recovered, that would still provide about a billion
liters, or 264,000,000 gallons of fresh water daily.
