The Jellyfish Barge is a floating greenhouse module that uses hydroponic agriculture and 70% less water compared to traditional agriculture. The barge is made of recyclable materials and uses solar distillation to collect 150 liters of saltwater daily and turn it into freshwater. 15% seawater is added back into the water to improve the mineral content and nutritional value of the crops. One module is approximately 70 square meters[1] and can be used to grow between 1400 and 1600 plants per month.[2] 120 units can be constructed on a hectare.[3] The project was included as part of the Expo 2015 in Milan, Italy. The project was conceptualized by Stefano Mancuso[4] and was financed by the Cassa di Risparmio di Firenze.[5] The architects of the module are Antonio Girardi and Cristina Favretto.[6][7]
