MIT engineers create solar-powered desalination system producing 5,000 liters of water daily

MIT's solar desalination system generates 5,000 liters daily without batteries.

: MIT engineers created a solar desalination system efficiently producing 5,000 liters of water daily without batteries. The system, led by Professor Amos Winter, adapts to sunlight variations using electrodialysis and a control strategy called 'flow-commanded current control.' Tested in New Mexico, it aims to benefit inland communities with limited seawater access. Supported by MIT and other organizations, it could revolutionize access to sustainable water.

MIT engineers have developed a solar-powered desalination system that efficiently generates up to 5,000 liters of clean water daily without relying on batteries. This innovative system makes optimal use of solar energy, adjusting to changes in sunlight through its 'flow-commanded current control' strategy.

The system employs electrodialysis to remove salt ions using electric fields, featuring dynamic adjustments in desalination according to available solar power. This technology could significantly impact inland communities with scarce resources, where groundwater is often brackish, especially in areas affected by climate change.

The team tested a community-scale prototype in New Mexico, revealing its ability to support around 3,000 people. Supported by the National Science Foundation and others, MIT plans further tests and broader implementation, with hopes of launching a company to expand access to sustainable water solutions worldwide.
