DailyDirt: Separating Salt From Seawater...

from the urls-we-dig-up dept

There's plenty of water on our planet, but unfortunately for us, not all of that water is drinkable or easily obtained. A whole ocean of water is even locked away underground trapped in minerals that we hopefully won't need to tap into for fresh water. However, drought conditions could get worse, so we might have to explore more exotic ways of getting potable water. Here are just a few desalination technologies that might become useful soon. If you'd like to read more awesome and interesting stuff, check out this unrelated (but not entirely random!) Techdirt post via StumbleUpon.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

    Maybe ... if we stopped polluting our easily accessible water supply - awwwwww crap, that will never happen.

    2.nd example seems to be little outdated. US Army has already patented it...

    Moving Water

    Some thing to keep in mind, a lot of the energy burned up in getting fresh water is simply getting it from sea level to hundreds of metres above sea level and tens of thousands of metres from the sea where it can be used.
    So not just getting the salt out.
    Moving water around is easy when you get gravity to do the work.

    "We were able to kill or remove approximately 99% of viable E Coli bacteria present in the feedwater upon flowing through the shock electrodialysis device with applied voltage."

    OK, everyone who wouldn't mind if every 100th glass of water you drank had lots of E Coli in it, please raise your hands.
