This aptly-named personal device could become one of the greatest life-savers in history. The LifeStraw is a 25 cm long, 29 mm diameter, plastic pipe filter. 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. The world’s most prolific killer though is diarrhoeal disease from bacteria like typhoid, cholera, e. coli, salmonella and many others. Millions of people perish every year because they simply don’t have clean water to drink. Until now, there was not much we could do about this because systems to clean water were costly and required electricity and spare parts and and and … but the LifeStraw now offers a viable means of saving tens of millions of lives every year. 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.

If we (as in the big WE) can find a way of manufacturing and distributing one of these to each human at risk, every year, we could save countless lives (now there’s a noble outcome for the tech blogs and mags of the world to work together to promote this). Each LifeStraw lasts for one person’s annual needs of clean water – a simple straw costing a few dollars will ensure that one at-risk person will not die for a year - now that's a donation we can all make with a serious kicker!

If this works, it could save millions indeed. I'd donate for this project.
