Safe Drinking Water - From The Toilet!

You wouldn’t want to, but if you HAD to, you could now drink from a water source that had fecal matter floating in it!
The water purification revolution moves on a pace with a new invention by Michael Pritchard of Ipswich (UK). Inspired by seeing disaster relief teams unable to provide safe drinking water after the 2004 tsunami and again in the aftermath of Katrina, Pritchard set to work. At £190 ($380) it’s not cheap, yet, but prices are expected to fall as demand grows.
Up until now even the best filter has only removed bacteria 200 nanometres long from water. Viruses are typically only 25 nanometres long and would pass through the filter. Pritchard’s invention, which filters right down to 15 nanometres means instant access to safe water whatever the circumstances. Amazingly one filter is said to be good for 4,000 liters.
