Waterblogged.info’s desalination update!


Scroll down to view yet another slew of useful Web resources about everyone’s favorite using-technology-as-a-panacea-for-averting-catastrophe solution: Desalination! These will be duly added to our ever-expanding compendium, Getting serious with Waterblogged.info: desalination. We note that recent developments appear to indicate that proponents of reverse osmosis (RO) are being challenged here and there by desal technologies based on solar distillation and deionization.

We’re on record as not being big on massive-scale desalination here at Waterblogged.info. At least not RO, which is energy-intensive, environmentally destructive, and excessively complicated.

Today’s idiosyncratic, ecentric rant from the picky people who bring you Waterblogged.info: Reverse osmosis (RO) is from our point of view, a misleading misnomer. Osmosis is a basic, natural process; so-called reverse osmosis is really power-assisted filtration. Why do we call it osmosis? There’s nothing osmotic about it. Just had to get that off our chests.

Teatro del agua: Visionary project proposed for the Canary Islands. A combination water desalination plant and beautiful outdoor theater. Our chief archivist just realized that we’d already posted something about this, linking from the glorious Pruned. YouTube marketing video here.

Relatively recent invention of more efficient? desalination membrane technology: Researchers at the UCLA Henry Samueli School of Engineering and Applied Science today (11/06/06) announced they have developed a new reverse osmosis (RO) membrane that promises to reduce the cost of seawater desalination and wastewater reclamation. A startup, NanoH2O, is betting on this technology. An MIT Technology Review article and an Economist article assess the new technology and mention NanoH2O.
