the astounding energy potential of the Marshall Hydrothermal Recovery
System is its use as the first practical deep-sea mining system.
appears to be black smoke exiting the vent is actually a highly
concentrated mineral and metal cocktail drawn from the center of
the Earth itself. When these materials hit the frigid waters of
the deep sea, they precipitate out of the fluid and rain down upon
the seabed below.
contained in the vent fluid includes iron, gold, silver, copper,
zinc, cadmium, manganese, and sulfur, along with significant amounts
of methane gas mixed into the fluid. Halides, sulphates, chromates,
molybdates and tungstates are also abundant. For this reason, the
best surface mines are located over hydrothermal veins of the geologic
the fluid is trapped, the materials it contains are also brought
to the surface through the pipe structure previously discussed.
The slurry left over after the heat is extracted can be loaded aboard
ships for processing elsewhere, or processed on-site.
human history, people have dug, scraped, ripped, and torn at the
earth in order to obtain needed materials from it. In the Marshall
Hydrothermal Recovery System, the earth for the first time is freely
offering her bounty. It is simply gratefully accepted, and the desired
minerals and metals are removed from what is given.
