Do I get this right? - they concentrate salt water once to get "heavier than sea water" brine. Hope not chlorinated. - it's then a closed system shuffling bet

Do I get this right? - they concentrate salt water once to get "heavier than sea water" brine. Hope not chlorinated. - it's then a closed system shuffling between bottom and top tank(s) - everything floating is soft, so no strong forces unless a wave crashes on top - advantage of ocean: "free standing" within height/depth margins, free water for initial fill And really not visible in the video: - the disk you see floating is a V shaped bladder with the storage in the V below surface and floatation sprinkled all around and segmented in to "cake wedges".
