gizmag Article: The LifeStraw – the invention of the century?

"The aptly-named LifeStraw is an invention that could become one of the greatest life-savers in history. It is a 25 cm long, 29 mm diameter, plastic pipe filter and purchased singly, costs around US2.00. The most prolific killer of human beings in developed countries is the automobile, followed by a host of diseases resulting mainly from an indulgent lifestyle."

Considering that US$2.00 might as well be US$1000.00 in some of these places that need the LifeStraw, I don't exactly expect them to be flying off the shelves in these impoverished countries. On the other hand, the price of gas (currently averaging $2,473.99 9/10 per gallon!) must be saving lives everyday, so I guess you have the yin and the yang.
