To me, this appears to be a welcome breakthrough technology, and one that can be scaled. 2/3rds of the planet covered in water - but it's salt water: "water water everywhere, but not a drop to drink." This might just change everything about a lack of clean, potable water in many places on the planet. :clapping: :highfive: :bigsmile: :star: :sun:
Here's the link to the article at MIT, and a snippet of text:

As the availability of clean, potable water becomes an increasingly urgent issue in many parts of the world, researchers are searching for new ways to treat salty, brackish or contaminated water to make it usable. Now a team at MIT has come up with an innovative approach that, unlike most traditional desalination systems, does not separate ions or water molecules with filters, which can become clogged, or boiling, which consumes great amounts of energy.
Instead, the system uses an electrically driven shockwave within a stream of flowing water, which pushes salty water to one side of the flow and fresh water to the other, allowing easy separation of the two streams.
