> "The new method requires so little energy that it can run on a store-bought battery." We currently have techniques that require no additional power (just using the sun), but almost every desal operation uses a powered method. Power consumption isn't the only factor here. A low power technique that has throughput per area equivalent to solar stills is just worse than all available alternatives. If you made a device that turns the briny sludge byproduct into fuel or some other consumable, that would be amazing.
