Here's a remarkable invention: The LifeStraw water-purification system is a plastic straw with multi-stage filters and a chamber of iodine impregnated beads. Here's an excerpt from the article over at Gizmag (via Engadget):

LifeStraw is a personal, low-cost water purification tool with a life time of 700 litres – approximately one year of water consumption for one person. Positive test results have been achieved on tap, turbid and saline water against common waterborne bacteria such as Salmonella, Shigella, Enterococcus and Staphylococcu.

And it's supposed to cost two dollars (USD) when it becomes available next year. It could save hundreds of thousands of lives in the Third World annually.
