Water sanitation innovation

WashPost:

Last year, Ugarte’s team partnered with Alfredo Zolezzi, Chief Innovation Officer of Chile Advanced Innovation Center, to test a revolutionary pint-sized Plasma Water Sanitation System that his company was developing. This can purify 35 liters of water in five minutes using only the power required to light a 100 watt bulb. If the system can be mass produced for less than $100, as Zolezzi believes, and the output passes the lab tests to which it is being subjected, it has the potential to provide clean, safe water to billions in the developing world. 

There are several projects similar to this being tested right now around the world. Once cheap enough, they have the potential to be a game changing technology to help improve the health of people around the hemisphere.
