That device takes in urea, which is present in urine, and uses it to generate a useful electrical charge. [Josh] has, of course, named this device the P Cell. An early proof of concept uses urine ...

Urine contains water, urea and salts. Urea is produced in the liver when excess amino acids are broken down. Urea is the main waste product removed in the urine, as it is not reabsorbed in the kidney.

Urine is seen as a source of fertilizer because ... The result was then placed in a wastewater solution with a high concentration of urea. Next, the team applied an electric current.

A more efficient way to extract fertiliser from human urine could help make better use of wastewater in cities and farms, without exacerbating global warming. Human urine is rich in compounds ...

The molecules which are not selectively reabsorbed (the urea, excess water and ions) continue along the nephron tubule to the collecting ducts as urine. This eventually passes down to the bladder.
