Well, it says in the abstract (and they have further detailed calculations in the paper) that they achieved an average desalination rate of 1.76 kg/m^2/h. So that’s about 1 gallon of water in one hour with 2 m^2 panel. That said, they did their tests using a 9 cm^2 panel, so yields may change significantly on scale up. Not sure if that translates into meaningful cost savings at scale, but it does seem like a significant advance in solar desalination technology. It seems like the paper was focused mostly on salt harvesting, though, rather than desalination. So I expect the real utility to be the combination of the two rather than desalination by itself, if it scales.
