Making bricks from human urine

Students at the University of Cape Town have created the first ever bio-bricks made of human urine. They mixed last night?s liquids with sand and bacteria to unlock calcium carbonate (a bonding agent) in the urine. The mixture is placed in moulds and hardens (surprisingly) at room temperature. Creating useable bricks out of urine is clever, but doing it without the usual energy-intensive firing process is outstanding.
