A team of scientists from MIT and Shanghai Jiao Tong University have developed a solar-powered desalination system capable of creating drinkable water at a higher volume and lower cost than existing methods.
The research, titled "Extreme salt-resisting multistage solar distillation with thermohaline convection" was published in the journal Joule. Electrek reported that the system is designed to not require electricity, thus significantly reducing the cost of water production.
The device, a small box, creates water eddies that function similarly to the ocean's thermohaline circulation. This process, combined with solar heat, facilitates water evaporation, leaving the salt behind.
