asteroza + mineral   21

Nice rough reference of of minerals in seawater, which could be captured via massive filtering. Gold doesn't look good, but Rubidium and Phosphorus don't look horrific...

Innovative lithium recovery technique from seawater by using world-first dialysis with a lithium ionic superconductor
More seawater mineral mining tech from japan. This follows on the heels of uranium collection membrane tech. Good source of brine+electricity would be an open cycle OTEC exhaust...

China plans nuclear deep-sea mining base (Wired UK)
Uh, must be doing teleops for robotic recovery of seabed nodules (perhaps via daughter submersibles), because anything else would be easier to suck up to a surface barge

If you accept that direct room temperature electrolysis has a poor efficiency, and that doing hydrogen production using mineral accreation electrodes in seawater has a similar efficiency, one can make the arguement that you might as well make the Biorock if you are going to do direct electrolysis anyways. You also create the semiporous seacrete/artifical rock that can be used as stable foundations for coral growth and ocean ecosystem recovery, or as a direct building material like concrete (though not high strength).

Green Revolution Cooling
Direct full server mineral oil immersion cooling is now possible with appropriate power supplies and SSD hard disks (rotating hard disks are actually air breathing). These guys are packing it as a 42U rack lying on it's back to allow easier single server removal, though frankly that would make a hell of a mess and it would be better to go with monolithic sealed units that fail in place...
