Michael Pritchard invented a new water bottle that filters out the dirtiest water and makes it drinkable. Clean water is usually taken for granted by those of us who live in places where it is readily accessible, so when we find ourselves in a situation where drinkable water isn't similarly available, we might find ourselves choosing dehydration over drinking what we find.

The appropriately named Lifesaver bottle, as seen in the picture, instantly filters out the water without the use of chemicals. The bottle even filters out fecal matter (yes, it cuts the **** out). Basically the water filters out anything longer than 15 nanometers.

Because of such a stringent filter, it even takes out viruses - typically 25 nanometers long - a feat even conventional water filters don't do. The filter automatically shuts off after it expires, preventing dirty water from coming through.

The idea was inspired in Pritchard after the tsunami disaster in South-East Asia last 2004 and Hurricane Katrina in Louisiana in 2005. Fresh, drinkable water was sparse in both situations and refugees had to wait for days for supplies. "Something had to be done. It took me a little while and some very frustrating prototypes but eventually I did it," said Pritchard.

The new invention, which can distill 4,000 to 6,000 litres without changing the filter, is expected to revolutionize the way water is supplied to disaster stricken areas, military troops, and happy campers everywhere.
