This is a video of a TED talk (It’s a pretty cool website) about a water purification bottle. Apparently they are being used in Africa to help fight against dehydration by providing instant clean drinking water. I watched this at school today and thought it would be cool to share and get some opinions on.

Here’s a link to one on Amazon:

Personally I think that they are just too expensive, I understand there need to make money and all, but for conventional at home use this is pretty steep. You have to buy replacement filters too so that’s another added expense. Although like stated in the video I think there should be no problem for governments to pay for considering how much they already spend on foreign aid. The U.S. last year spent around $50,000,000,000 (That’s billions) on foreign aid alone… According to the date on Amazon these bottles have been around for five years now, so why haven’t I heard of them until today?

Thoughts and opinions?
