Tapping seafloor volcanic vents

Modern ocean power systems look to convert the mechanical energy of waves or tidal movement to electrical energy. But that’s not all the sea has to offer. It may also be possible to capture and convert the enormous quantities of heat produced by magma escaping through seafloor vents—an undersea version of geothermal energy.
