What is a solar-powered desalination system?
MIT engineers built a solar-powered desalination system that produces large quantities of clean water despite variations in sunlight throughout the day. Because it requires no extra batteries, it offers a much more affordable way to produce drinking water, compared to other solar-driven designs.
Could a solar desalination system turn seawater into drinking water?
Engineers at MIT and in China are aiming to turn seawater into drinking water with a completely passive device that is inspired by the ocean, and powered by the sun. 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.
Are solar desalination technologies sustainable?
Solar desalination technologies have been successfully implemented in remote and water-scarce areas. The growing global demand for fresh water, coupled with the environmental impact of conventional desalination technologies, underscores the urgent need for more sustainable, energy-efficient solutions.
What is direct solar desalination?
Direct solar desalination Solar stills are one of the oldest and simplest forms of solar desalination. In a solar still, saline water is evaporated directly by solar energy and then condenses as distilled water .
Could a solar-powered desalination system serve off-grid arid coastal areas?
A completely passive solar-powered desalination system developed by researchers at MIT and in China 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.
Could a solar desalination system make water cheaper than tap water?
A new solar desalination system takes in saltwater and heats it with natural sunlight. The system flushes out accumulated salt, so replacement parts aren’t needed often, meaning the system could potentially produce drinking water that is cheaper than tap water.
