Turning urine into beer. Yes, that's a thing now - CNET

The next time a friend says, "This beer tastes like piss," you might think twice about where it came from.

That's because scientists at a Belgian university have created a machine that tus urine into drinkable water and fertilizer.

A machine like this could bring drinkable water to rural areas of the world that don't already have access to clean water, or could be installed in public places like airports, researcher Sebastiaan Derese told Reuters.

Or, it could be used to make beer. Bear Grylls would be so proud.

Here's how it works: The machine uses solar energy to heat urine that's been collected in a boiler. The urine is then put through a membrane that separates the water from nutrients like potassium, phosphorous and nitrogen.
