Michael Pritchard's water filter turns filthy water drinkable

From TED: Too much of the world lacks access to clean drinking water. Engineer Michael Pritchard did something about it -- inventing the portable Lifesaver filter, which can make the most revolting water drinkable in seconds. An amazing demo from TEDGlobal 2009.

Well, that simply could not be any more impressive. A total solution to the entire water problems of the planet. Too good - but still true !

Now this is cool technology. However I worry that this is not just providing a "band-aid" and not addressing more long standing issues such as fuel consumption for boiling water (the most tried and true method of water sterilization). In sustainable technology, we must realize when our tech is not what is needed for the world at the moment, and "step aside" for those with more far reaching needs. Though this technology is absolutely freaking brilliant, I wonder if a new cheaply produced stove that boosts fuel usage efficiency might not be much more effective at providing for a range of issues from hygiene to drinking water. I personally favor ideas (as I am sure many of you have heard of) such as the briquettes or small brick stoves. I do however really like the idea that this product is not offered for free. People often don't have a want to change to a new system when it is not "desirable". Make it popular by making one need to purchase it, and vola, the rich buy it, the poor want it, and it is used (as a paraphrase to how the theory goes).

This is a brilliant bit of technology- honestly, I'd want one just so I could drink on the go while at the beach, outdoors, etc. However, for it to succeed, it really needs exposure so people can latch onto it, see it, and this demonstration really works. I like it a lot, so I may have to throw this one up somewhere in hopes of it getting more fully embraced. Very topical considering the recent Haiti crisis. Thanks for passing it on!
