The US military has devised a way to ensure its troops in battle need never go hungry – with dried food that can be rehydrated using dirty water or urine.
The meal comes in a pouch that filters out 99.9% of bacteria and most toxic chemicals, says New Scientist magazine. “The pouch – containing chicken and rice – relies on osmosis to filter the water or urine,” the New Scientist Magazine reported.
The liquid passes through a membrane, thin sheets of a cellulose-based plastic with gaps just 0.5 nanometres wide. It means only clean water can reach the food, and the bacteria is left behind.
