Ghanaian water bags

You can't drink the tap water in Ghana - assuming that there is tap water in the first place. That said, fresh drinkable water is never far from reach. Fresh, purified water is for sale pretty much everywhere. It's difficult to scan an average scene in Ghana and not see someone wandering around selling sachets of water, just like the lady in the picture above. Ghanaians bite a tiny bit off the corner of the sachets and drink the water straight from the bag.

The guys at Maker Afircan Faire were thinking about what else they can do with these bags and came up with some interesting ideas including how they could use the bag to generate electricity by using them to create small turbines. Read more on their blog over here.
