The heat catalyzes reactions that leach metals from the rocks into the fluids. The hot fluids—which can reach up to 750°F (400°C) under the pressure in the deep—rise buoyantly back to the seafloor. As they emerge from the crust, they encounter cold water, which causes metal sulfides to precipitate out of the fluids and form solid deposits ...

The study, published online in Environmental Science & Technology Letters, demonstrates that TSSE can desalinate very high-salinity brines, up to seven times the concentration of seawater. This is a good deal more than reverse osmosis, the gold-standard for seawater desalination, and can handle approximately twice the seawater salt concentrations.

When CO 2 dissolves in seawater, it produces carbonic acid as a byproduct. When you add lime to seawater, it reacts with that acid and neutralizes it, forming a carbonate ion. The effect is a boost in alkalinity to the ocean, and greater ocean alkalinity means more CO 2 can be absorbed. The boost in alkalinity also reduces the amount of CO 2 released by an overwhelmed ocean.
