We need technology that makes the lives of the poor easier – got enough high tech gadgets. Here’s a decidedly smart but low tech way of doing water purification…

Students Invent Water Purification Disc That Could Revolutionize Clean Water Access – Video 3min

Students at the University of Virginia have developed a new way of purifying water that they say could bring improved water quality for millions in the developing world.  It’s called a Madi Drop. Field testing begins this month in South Africa.

What’s created is called a MadiDrop – a ceramic disc infused with silver.

When dropped in water, silver ions, which are atoms that have an electrical charge,, are released to purify the water.  And, testing here at the University of Virginia shows clean, safe water.

“It’s not just about making a really great technology that effectively removes or kills bacteria and pathogens.  It’s about making a low cost, simple to use one, tailored to people in developing countries who don’t have many resources,” said Beeta Ehdaie, a doctoral candidate at UVA.
