I just watched this recent TED talk. If you don't regularly watch the podcasts posted on TED.com, you really ought to.
In light of SLIM's recent accomplishments in water provision, this is an interesting afterthought.
The bottles are expensive, but we might want to try it out. Who knows, maybe they'll give us a discount is we write to the guy that designed them? I was thinking it might be a nice thing to give to the CBOs' top volunteers. There is currently no incentive for them, but this might be an interesting thing to present them with. Just a thought. I still think the wells are better considering the size of the CBOs, but these bottles seem great for more remote areas where people are more spread out.
