In light of this morning’s post on bottled water, it’s worth watching this short TED presentation by inventor Michael Pritchard on his “Lifesaver” water filter bottle. One of the arguments that bottled water companies employ in support of their product is that, in emergencies, ‘clean, safe’ bottled water is the only viable option. But as Pritchard points out, even in the US, it took five days (five days!) to get bottled water to the Superdome after hurricane Katrina. What’s more, by forcing people to congregate around bottle distribution points (whether they’re football stadiums or refugee camps) in order to have access to water, the problems of sanitation and disease are perpetuated.

But Pritchard is thinking different about more than just emergency situations: he may just have a solution to making a serious dent in providing sanitary water worldwide. Also, it’s fun to watch a guy drink from water that moments before was full of rabbit shit. Check it out:
