Solar-powered desalination device wins MIT $100K competition

But what are the use cases for a device that filters 0.3L of water an hour using 20W - that's still a fair amount of electricity?

There are many ways to use the sun to desalinate that seem more appropriate to getting drinking water to humans in poor parts of the world.

For example, this is another MIT project: https://news.mit.edu/2022/solar-desalination-system-inexpens...

According to them, their prototype does use 20Wh per liter and produces 0.3 liters per hour. It’s not 20Wh per 0.3 liters. That’s USB charger level of electricity, my 100 EUR foldable solar charger produces more on a good day.

The interesting part about this is probably that even the prototype is fairly compact and weighs like 10kg and that they claim to be able to achieve that with brackish water. If they can prove that it’s as robust as claimed, that sounds like an interesting technology.
