Marshall Hydrothermal Recovery Systems digs in deep for fuel, electricity and minerals

The Marshall Hydrothermal Recovery System is going to use heat from hydrothermal vents 7,000 feet under the sea to make electricity. But they plan to try and avoid too much destruction to the underground ecology as it plans to relocate the local flora and fauna to another vent nearby by having alternative methods to bring water and generate electricity. As much as 264 million gallons of fresh water can be collected daily and as much as a gigawatt per vent of electricity can be generated. The materials in these geologically ancient vent fluids include iron, gold, silver, copper, zinc, cadmium, manganese, and sulfur. Halides, sulphates, chromates, molybdates and tungstates are also abundant. So with one stone three purposes served.
