Gabriel Luna-Sandoval, a Mexican scientist and professor at the University of Sonora, has developed a new simple method that can turn the urine fluid into biogas, which can then be used to cook meals, heat homes and running water.

The urine is stored in a transparent 8-inch square machine, invented by Lune-Sandoval. Electricity is passed through the stainless steel electrodes attached in the square to extract the useful gases. The machine, which can be filled in a day by a single individual, can provide gas enough for a family of four for one week.

Currently, the building cost for the square cell is valued at USD $420 and the scientist is looking into reducing the cost to make in affordable to the average Mexican citizen.

Scientists have been looking into new ways to reuse urine for the benefit of urban cities and rural areas.
