☀️💧 Solar-powered desalination system is cheap enough to solve the world’s drinking water shortage
MIT and Shanghai researchers created a solar desalination system that transforms seawater into affordable drinking water, using only sunlight.
Engineers at MIT and Shanghai Jiao Tong University in China are working on an innovative solar-powered desalination system to convert seawater into drinkable water. The system aims to provide clean water more affordably than tap water.
In a study published in Joule, the researchers outlined their design for a passive desalination device. This system uses natural sunlight to heat seawater, promoting evaporation and leaving salt behind. The water vapor is then condensed into pure drinking water.
What sets this system apart from others is its ability to avoid clogging by keeping the salt in motion. Salt accumulation can be a major issue in desalination systems, but the team’s design ensures the salt is continuously flushed out instead of building up and blocking the system.
The potential impact is significant. The researchers estimate that a device about the size of a small suitcase could generate 4 to 6 liters of drinkable water per hour. This small-scale system could supply enough water to meet the needs of a small family. At this scale, it could even provide cheaper water than tap water, according to Lenan Zhang, a research scientist at MIT.

A 65-year-old couple retiring in 2025 with average earnings will receive an estimated $1.34 million in lifetime benefits, while contributing only $720,000 in today’s dollars.
That shortfall—more than $600,000 per couple—is being made up by younger workers.
