Remarkable bit of design/engineering :thumbup:

Simple, solar-powered water desalination
System achieves new level of efficiency in harnessing sunlight to make fresh potable water from seawater
February 7, 2020
Massachusetts Institute of Technology
A completely passive solar-powered desalination system could provide more than 1.5 gallons of fresh drinking water per hour for every square meter of solar collecting area. Such systems could potentially serve off-grid arid coastal areas to provide an efficient, low-cost water source.

The team estimates that a system with a roughly 1-square-meter solar collecting area could meet the daily drinking water needs of one person. In production, they think a system built to serve the needs of a family might be built for around $100.
