The solar-powered system removes salt from water at a pace that closely follows changes in solar energy. As sunlight increases through the day, the system ramps up its desalting process and automatically adjusts to any sudden variation in sunlight, for example by dialing down in response to a passing cloud or revving up as the skies clear.

Solar-powered desalination unit, device that transforms salt water into drinking water by converting the Sun''s energy to heat to drive the desalination process. Solar desalination mimics Earth''s natural water cycle and has been practiced by humans since ancient times.
Indirect solar desalination systems comprise two sub-systems: a solar collection system and a desalination system. The solar collection system is used, either to collect heat using solar collectors and supply it via a heat exchanger to a thermal desalination process, or to convert electromagnetic solar radiation to electricity using photovoltaic cells to power an electricity
MIT engineers have built a solar-powered desalination system that "ramps up its desalting process and automatically adjusts to any sudden variation in sunlight, for example by dialing down in response to a passing cloud or revving up as the skies clear."

MIT engineers have built a new desalination system that runs with the rhythms of the sun. The solar-powered system removes salt from water at a pace that closely follows changes in solar energy.
The challenge of global water scarcity, exacerbated by population growth, pollution, and uneven resource distribution, demands innovative solutions. Seawater desalination, particularly Reverse Osmosis (RO) desalination technology, offers a promising remedy due to its efficiency, economic attractiveness, and enduring durability. This study explores the potential
This leads to an important hurdle when integrated with desalination technologies as intermittent energy generation cannot provide stable water production. To overcome it and introduce flexibility into solar desalination, battery storage systems and water storage tanks are employed 53.
In a paper appearing today in the journal Joule, the team outlines the design for a new solar desalination system that takes in saltwater and heats it with natural sunlight. The configuration of the device allows water to circulate in swirling eddies, in a manner similar to the much larger "thermohaline" circulation of the ocean.
The system delivered pure water that exceeded city drinking water standards, at a rate of 5.78 liters per square meter (about 1.52 gallons per 11 square feet) of solar collecting area. This is more than two times as much as the record amount previously produced by any such passive solar-powered desalination system, Wang says.
This cost-competitive, low-emission, solar-powered brackish water desalination technology can also reduce water waste through increased recovery ratios and enable the independence of water supply from grid infrastructure for rural areas in India and other resource-constrained countries.
