    1. Brine also contains metals and chemicals (foreign to the marine environment) that have adverse effects on marine ecosystem

      Brine also concentrates other materials, metal, chemicals. (at what point is brine dense enough to harvest such things)

    2. Because energy for desalination increases with seawater salinity, buildup of salt in brine endangers potable water supply there.

      pushing back brine into the sea means higher salinity and thus more energy needed for desalination.

    3. The Persian Gulf (also known as Arabian Gulf) is surrounded by desalination plants with about 50% of worldwide capacity to desalinate seawater. Most of these plants dispose of hypersaline effluent (brine) via surface and nearshore outfall into the Gulf

      some 50% of global desalination capacity is around the Persian gulf

    1. Desalination produces hypersaline brine, which, if discharged improperly, could raise salinity in parts of the Gulf of Oman by up to 1.5 times and increase water temperatures by 2°C, threatening marine ecosystems and already stressed fisheries.

      Issue w desalination is the resulting brine and its disposal. How does Israel (a net exporter of desalinated water) deal with that?

        • Since this simple design integrates fresh water and food production, it can be integrated as a module for a floating city.

    1. Existing techniques for probing bacteria’s electrochemical activity involve growing large batches of cells and measuring the activity of EET proteins — a meticulous, time-consuming process. Other techniques require rupturing a cell in order to purify and probe the proteins.
