Innovation

Or necessity is the mother of invention... any way you want to look at it, this is cool...

Fingers crossed!

Other systems need power to desalinate. These use the up/down action of the waves.

LOL. Lots of variables... have fun!

I was assistant manager at Morning Star Beach Club which was the luxury end of Frenchman’s Reef (now a Marriott) on St. Thomas 1989-91 and they had a desal plant for the hotel. It was sheer luxury on a water starved island to take lonnnnng showers plus the water tasted great.  I have no idea what the cost was to run it but tourists just never understand how to conserve water so it was probably cheaper in the long run.

I think it comes down to what the options are in the community that needs it. It would be more expensive in some communities and less expensive in others.

I loved the video, thanks for sharing.
