Freshwater from Salt Water using only Solar Energy
The majority of the planet’s surface may be water, but unfortunately a heaping pile of salt makes most of that undrinkable. Desalination makes saltwater more palatable and potable, but being a bit of an energy guzzler means it isn’t the most practical solution in off-grid situations. A new system makes use of nanoparticles to harness the power of the sun and distill water more efficiently, without needing electricity.
