Submission Statement: The linked article reports on a new solar-powered desalination system developed by engineers at MIT and in China that can produce freshwater from seawater at a lower cost than tap water. The system is inspired by the ocean’s thermohaline circulation and uses natural sunlight to heat and evaporate saltwater, leaving behind pure water vapor that can be condensed and collected. The system also avoids the salt-clogging issues that plague other passive solar desalination designs by circulating the leftover salt through and out of the device. The system is scalable and could provide enough drinking water for a small family or an off-grid coastal community. This article is collapse-related because it shows how technological innovation can address the global water crisis, which is exacerbated by climate change, population growth, and pollution.
