MIT’s Solar-Powered Desalination Machine Could Help Drought-Stricken Communities

A team from the Massachusetts Institute of Technology and Jain Irrigation Systems have come up with a method of turning brackish water into drinking water using renewable energy. With parts of the planet running dangerously low on fresh water, this technology can’t come soon enough.

This solar-powered machine is able to pull salt out of water and further disinfect the water with ultraviolet rays, making it suitable for irrigation and drinking. As the MIT News Office explained, “Electrodialysis works by passing a stream of water between two electrodes with opposite charges. Because the salt dissolved in water consists of positive and negative ions, the electrodes pull…
