- puzzledobserver 3y agoI like the videos posted by Practical Engineering, but I found this one unsatisfying. Both distillation and reverse osmosis are energy expensive, but this doesn't answer whether this is because these are poor techniques or because desalinating water is fundamentally+physically difficult. Are there thermodynamic limits to how efficiently water can be desalinated? Doesn't this feel like a problem where a Carnot-like argument can be made?
