water purification

Dean Kamen has invented a special water purifier called the Slingshot and this device is supposedly one of the most innovative water purifiers on the market. Can it make a difference especially in the technologically-deprived areas in third world countries?

What would you spend £1.50 on? A couple of downloads from iTunes? A tube ticket? A bag of hand-cooked chips? In Africa, £1.50 could buy a water purification device, so that children can drink water from their local source, safe in the knowledge that it will not give them a life-threatening illness.

What if you could weave a parabolic basket while helping to eradicate non-native invasive species, and line it with a waste stream (or recycle-stream at best) product to create an almost-free solar cooker and pasteurizer? Well this group has laid the ground work, and created a functioning prototype.

Good design can save lives and improve human society. That’s the thought behind the Solar Bottle by Italian designers Alberto Medo and Francisco Gomez Paz. Winner of a 2007 INDEX award, the sleekly designed Solar Bottle uses simple solar technology to purify dirty drinking water and prevent water-born diseases.
