  • A new desalination method produces drinking water from seawater without chemical additives.

  • The solar-powered system uses specially engineered black metal to absorb sunlight.

  • Its self-cleaning surface separates and collects salts, instead of dumping them as harmful brine waste.

  • From the salts, the system can extract lithium, a key material for rechargeable batteries.

  • The approach could help address global water shortages and growing mineral demand.

Solar distillation with a novel approach to dealing with the salt left after the water evaporates. Pretty neat.
