  ‘ In their study, the researchers describe their device as a “microenvironment-engineered, multilayered electrode design for sustainable seawater electrolysis.” When in operation, the apparatus delivers “a geometric current density of 1 A cm⁻² in real seawater at an overpotential of 420 mV, with no hypochlorite formation and outstanding operational stability for 300 hours at room temperature.” ‘

  I think this could potentially be the solution for combustion powered generators or power plants fueling data centers. If they had a way to farm hydrogen using this technology and utilized hydrogen fuel cells it would be a game changer in many ways.

  Ummmm, and undo millions of years of anerobic generation of water molecules by planktons and algae?
