Summary

TLDRMIT engineers have developed an innovative solar-powered desalination system inspired by ocean thermal circulation. This passive device efficiently converts seawater into drinkable water without the need for salt-clogging filters. With a higher water production and salt rejection rate than other passive concepts, it could potentially produce fresh water cheaper than tap water when scaled up to a suitcase size, offering a sustainable solution for water scarcity.
