Yep. If the filters and cleaning can be done cheaply, start buying desert islands that nobody wants currently. I understand this tech is capable of desalination. Desert coasts and islands will suddenly gain value.
Yes, and the filters are being produced in existing formats, meaning they are immediately interchangeable with filters currently in use, thereby eliminating the need for refitting desal plants.
But wait, there's more! In a convergence of leading edge technologies, the Koreans are working on producing cost effective carbon nanotube desal filters with 3D printing.
