  #Nighthawk #video about #electrolysis for, e.g., electrowinning metal #materials. First big science error is at 8'08": “Actually everything that dissolves in water splits into ions when it does so.” Nope. He claims to be making #DIY ion-selective membranes using Robert Rowow’s recipe, using off-the-shelf PVC cement and ion-exchange resin beads from water softeners, reinforced with fiberglass cloth, but I’m not clear how he validates them. He recommends using a hot glue gun to hold the membranes in place in his water buckets with EVA. He also turns carbon welding blankets into conductive carbon felt electrodes. He reports 250mA at 1.2 volts from his semipermeable-membrane plastic-bucket Fe⁺⁺/Fe⁺⁺⁺ flow battery with roughly A5-paper-sized carbon-fiber electrodes. Also he makes hydrogen sealed into the cathode compartment of a cell with one of these semipermeable membranes.
