The Life Saver water bottle is a military grade water sanitizer that can make the dirtiest of water drinkable in seconds. The bottle not only filters out bacteria, but also takes care of viruses and water that has been contaminated by fecal matter. The creator, Michael Pritchard, initially came up with the idea after watching victims of Hurricane Katrina and the 2004 tsunami in Asia go for days without receiving clean water. There are others, however, that are interested in Pritchard's invention. After showing the bottle off at a defense conference in the UK, Pritchard sold all 1,000 of his $385 bottles in under four hours. Defense experts were impressed with the fact that it could filter 4,000 or 6,000 liters before the filter had to be replaced. An innovation such as this could have a significant impact if it ever reached the consumer market, not only being used as emergency gear, but for camping and travel as well.
