An assistant professor at the University of Southern California, Aroussiak Gabrielian, recently came up with a novel project consisting of a vest with a vegetable garden growing on it. Her project draws inspiration from French botanist Patrick Blanc's gardens, which were both soilless and vertical. The vest has a layer of moisture retention fabric on it because the garden is fuelled by the wearer's urine. "The idea is to capture the urine via a catheter filtered through a process called forward osmosis, which is developed by NASA technology that is currently used in space, and delivered to the crops as irrigation," said Gabrielian.
