Filter-free desalinator for $1500

MIT researchers have developed a prototype of a device that can turn seawater into safe drinking water. At this time this is just a concept project for a membrane-free, low power and affordable desalination system.

https://spectrum.ieee.org/portable-d...on-filter-free

MIT rsearchers used ion-concentration polarization snd electrodialysis to separate the salt from the water, instead of using filters and high-pressure pumps.

If they succeed in improving the yield and progress to commercialization these could displace traditional watermakers on cruising boats.

Re: Filter-free desalinator for $1500

hmmmm "...0.3 liters of potable drinking water per hour, while consuming a minuscule 9 watt-hours of energy...."

0.3 liters per hour does not seem like much, but maybe the power used is appropriate (cannot be bothered to work it out)

cheers,
