According to a 2010 UN-Water study, there are an estimated 900 million people living without access to safe drinking water. That's one in every six people ingesting the nastiest of nasties on a daily basis.

And while global diplomats release reports and set aside millions of dollars to monitor the situation, which is showing some improvement, there exists a technology that could provide clean water on demand to anyone who holds it in their hand.

What is it, and how does it work? And will it be distributed, widely and cheaply, to the suffering masses? Science in Seconds takes a look.
