Today I watched a presentation by engineer Michael Pritchard. He has developed a technology that has the potential to solve the problem of access to safe drinking water. His Lifesaver water-purification bottle could revolutionize water-delivery systems in disaster-stricken areas around the globe. The bottle uses nanotechology to filter even the filthiest water into sterile, safe drinking water.

Truly life changing technology

Perhaps even more amazing: according to Pritchard, it would cost about 8 billion US dollars to hit one of the Millenium Goals of halving the number of people without access to safe drinking water. That is a lot of money, unless you put it in perspective: the UK government alone spends 12 billion UK Pound or 20 billion US dollars on foreign aid each year. That money would be sufficient to give every single human being on the planet access to safe drinking water. It would change the lives of 3.5 billion people and save the lives of 2 million children, every year!

The video below will explain it all in just 10 minutes.

This video was filmed in July 2009, at the TED Global conference in Oxford, UK.
