Filter-free desalinator for $1500

[macieknan]

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.

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.

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,
