It's a solar still that can operate continuously without maintenance as it doesn't get clogged with salt. That's a pretty nifty and practical achievement.
They're also proposing it be used at household scale, because the system is so small, rather than scaled up to factory scale.
Oh god, can you imagine the brine disposal problem with home use? People still pour motor oil down drains.
