Portable Solar Powered Desalination System A Reality

I’ve been clamoring for this kind of tech to break out of development status and into marketability for most of the last decade, and it’s just great to see it finally manifest in a way that allows for ease of transport and comparatively simple maintenance. In a world top-heavy with serious issues, this is a breath of fresh air … or more to the point, a drink of fresh water. Stephen C. Webster writes on RAW Story:

Desalination System

About one in eight humans do not have access to clean drinking water, according to the World Health Organization. That’s approximately 884 million people.

The repercussion of this reality are a daily reality in developing nations: an estimated 1.4 million children perish each year due to diarrhea brought on by waterborne bacteria. In spite of breathtaking advances in human technology, over 97 percent of the world’s water is still undrinkable.

And while salty or impure water can be cleaned through existing water desalination technologies, the facilities needed are massive and consume vast amounts of energy. It’s costly, too: purifying sea water can cost “over $1,000 per acre-foot,” according to the US Geological Survey. Even worse, of the roughly 12,500 desalination plants operating as of 2002, their combined total output was equal to less than 1 percent of humanity’s daily water consumption.

All of these factors combine to effectively place clean water out of reach for most of the world’s poor.

    Very cool technology, now the challenge is simply to make it more accessible.

    Beyond desalinization, just ensuring that all the little critters in existing fresh water are killed is important. To that end, there are now hand-crankable jugs that power a UV light to kill germs in the water.

      Thats awesome! Also…the “Lifestraw” has started getting street cred as a disaster response tool to give people when water safety is an issue. There are plenty of things that suck…but at least some of the big issues are getting some thoughtful, creative treatment.

I'm far from a Luddite when it comes to technology, but kinda of amazed to see this video as a Google ad. (Really should never from now on be surprised...
