The Lifesaver bottle is a portable water purification device. Designed by Michael Pritchard, the bottle filters out objects larger than 15 nanometres. The bottle is used by people hit by disasters to create safe drinking water or while camping. It is also used by impoverished people around the world to make safe drinking water.
Development
After the 2004 Asian Tsunami and Hurricane Katrina disaster in the U.S., Michael Pritchard, a water-treatment expert in Ipswich, England began to develop the Lifesaver bottle after hearing the idea from Dr. Zackary Kepes and Austin Castellano. Pritchard presented a prototype of the Lifesaver at 2007′s DSEi London, where the product was named “Best Technological Development”.Pritchard’s entire stock of 1,000 bottles sold out within four hours of the presentation.
Speaking at TED in 2009, Pritchard estimated that by utilising the Lifesaver bottle reaching the Millennium Development Goals of halving the number of people without drinking water will cost $8 billion; while $20 billion would provide drinking water for everyone on Earth. Continue reading

It feels fair to say that when ‘Captain America’ was first announced, no one outside of the 50 states was expecting anything special. As the film’s subtitle alleges, the Captain may be ‘The First Avenger’ but he’s still a patriotic prat in tights whose main powers, much like the real-world superpower that spawned him, seem to be excessive arrogance and blunt force.
