Engineers at MIT and in China are aiming to turn seawater into drinking water with a completely passive device that is inspired by the ocean, and powered by the sun.

In a paper appearing today in the journal Joule, the team outlines the design for a new solar desalination system that takes in saltwater and heats it with natural sunlight.

The researchers estimate that if the system is scaled up to the size of a small suitcase, it could produce about 4 to 6 liters of drinking water per hour and last several years before requiring replacement parts. At this scale and performance, the system could produce drinking water at a rate and price that is cheaper than tap water.

    That’s what I always thought, but the local effects of hypersalinated water can be terrible for any nearby life

      While true, I consider the issue very minor compared to getting people clean drinking water. There are no perfect solutions in society. Just a series of trade-offs, maximising benefits and minimising costs.

          Large coastal communities don’t just go down to the local jetty and cast hooks into the water by the shore. Commercial fishing is done by large ships out in the ocean, far away from the cities.

          You probably wouldn’t want to fish near a city’s sewer outflows anyway.
