According to MIT, this technology works even at small scale, with one the size of a suitcase able to desalinate 6 litres per hour, and only needing to be serviced every few years.

Here's a video detailing how it works.

200 liters is with bathing, cooking, toilets, and all the other conveniences of modern life in industrialized Western society.

This device is aimed at small scale off grid household use - people who don't have public water or sewer and naturally use much less.

And if you notice, the device is fueled by sunlight - so it needs a 2x2 square of shallow water for each "suitcase". The devices can't stack on top of one another. If you start putting these down along the coast you quickly run out of space.

This is to supply fresh water for poor coastal villages. It doesn't scale to cities.
