Michael Pritchard of Ipswich, UK, has invented a bottle that makes foul-smelling, infected or polluted water drinkable in seconds. Pritchard hopes the bottle will find use in disaster regions where access to clean drinking water is vital. The military, however, seems to become his first customers. The military think the bottles will have huge benefits for soldiers who hate drinking iodine-flavoured water. Michael Pritchard’s water purification bottle can clean up any water - including fecal matter - using a filter that cuts out anything longer than 15 nanometers, which means that even viruses can be filtered out without the use of chemicals. That is pretty amazing, but it does not come cheap. The bottles are GBP 190.
