Desalination system could produce freshwater that is cheaper than tap water (news.mit.edu)

Engineers at MIT and in China are aiming to turn seawater into drinking water with a completely passive device that is inspired by the ocean, and powered by the sun.

In a paper appearing today in the journal Joule, the team outlines the design for a new solar desalination system that takes in saltwater and heats it with natural sunlight.

The researchers estimate that if the system is scaled up to the size of a small suitcase, it could produce about 4 to 6 liters of drinking water per hour and last several years before requiring replacement parts. At this scale and performance, the system could produce drinking water at a rate and price that is cheaper than tap water.

They do this anyway...what do u think a water tower is???

Water towers are designed to provide steady pressure through demand spikes. That's completely different from transporting the water.

you are completely missing the point mate.

desalinated water STARTS at the lowest possible point in the catchment. Rain water does not.
