Belgian Scientists Create A Machine That Turns Pee Into A Drinkable Beverage

Researchers have created a device that uses solar energy to turn urine into drinkable water, which can then be used to brew beer. ...would you drink?

After a few beers, you can find yourself needing to rush to the toilet to relieve yourself. But there may soon be a way to reverse this process, using urine to relieve thirst. 

The team of scientists at Ghent University say their technique could be applied in rural areas and developing countries. 

While other options for treating waste water already exist, the researchers say their new system is more energy-efficient and could be applied in areas off the electricity grid.

Dr Sebastiaan Derese, who worked on the device, said: 'We're able to recover fertilizer and
drinking water from urine using just a simple process and solar energy.'

The device collects urine in a large tank, heating it using a solar-powered boiler. The heated urine then passes through a membrane, which separates out the water, as well as nutrients such as potassium, nitrogen and phosphorous. 

The nutrients collected can then be used to make fertilisers. Water collected can be used to brew beer.
