[–] rini17 4mo ago ↗ Does it solve the brine problem? Usually the seawater must be heavily treated first before desalination and the resulting brine causes ecological problems when discharged. [–] westurner 4mo ago ↗ This system requires a subsequent RO Reverse Osmosis system because it only removes so much of the Na salts (which it makes into Na metal).It looks like stacking this system on this system would be even more efficient; https://news.ycombinator.com/item?id=48425376 :> "Extreme salt-resisting multistage solar distillation with thermohaline convection" (2023) https://www.cell.com/joule/fulltext/S2542-4351(23)00360-4 Which sustainable production processes take brine as an input?
