Watermaker - Gone With The Wynns
Watermakers are a sailor’s best friend.  Using the fabulous technology of reverse osmosis, we can turn almost any water source (including salt water) into squeaky clean drinking water.

Direct electrosynthesis of sodium hydroxide and hydrochloric acid from brine streams | Nature Catalysis
recycling output brine from desalination plants to make sodium hydroxide in bulk. Apparently desal plants normally have to buy it to adjust input salinities, so producing it's own makes some sense...

The optical duality of tellurium nanoparticles for broadband solar energy harvesting and efficient photothermal conversion | Science Advances
Putting the tellurium nanoparticles directly in the water sounds like a bad plan for an industrial process, but this might lead to a better solid absorber for a thermal receiver?

"Water Resource Challenges and Opportunities
for Water Technology Innovation

December 2015

At present, the cost and energy intensities of desalinated water are prohibitive for most communities, and particularly high for seawater which is higher in salinity than brackish water.

ambitious target levels would stand at less than $0.50 spent in total cost, 1 kWhe of energy consumed, and less than 1 pound of carbon dioxide generated over the course of producing 1 cubic meter of water.

Achieving these targets would require approximately a 4-times improvement in cost, a 3-times reduction in electricity usage, and a 2-times reduction in carbon dioxide emissions over existing seawater desalination technologies to achieve cost-competitive pipe parity."
