Urine technology, powered by a urine converter named 'GreenBox', has been proposed by Professor Gerardine Botte for future Mars missions. Gerardine Botte has invented GreenBox. Botte is director of Ohio University's Center for Electrochemical Engineering Research.
GreenBox is one of the finalists in a Mars One competition and is device that converts urine into energy and water. The Ohio University scientist expects that her 'pee power' technology will persuade the astronauts of future Mars missions to consume their own waste.
