Mexican engineer Gabriel Luna-Sandoval, a researcher at Sonora State University, invented a machine that he said can transform urine into a biogas to serve as a household heater to take hot showers or cook.
But the 41-year-old researcher from the University of Sonora State, in northern Mexico, is also shooting for the stars with his invention.
Luna-Sandoval has extracted oxygen (hydroxy gas) from urine, and he said that astronauts could take a small device in space to create O2 with their own bodily fluid in case of emergencies.
The idea has been taken seriously by the Mexican Space Agency, which told AFP in a statement that it is a "great innovation" with "high viability to be considered in space technology and for space walks."

Urine seems to be better suited for electrolysis and production of hydroxy gas than water. There have been several efforts to develop this, and the technology is not anything we can't handle.
