From Vincent Callebaut Architects, this impressive project is meant to navigate through the rivers in Europe in order to clean water and make it drinkable. Its name comes from “Physalia physalis”, meaning “water bubble”. It is a project whose idea came from a major global issue which is the fact that one billion people nowadays don’t have access to drinking water. The giant bubble will actually be a floating garden, completely independent in terms of energy. It is said that the prototype will even make more energy than that consumed. Solar cells and a double pneumatic membrane will form the roof of the construction and similar technologies will be used in order to reach its energy goal.  Inside there will be four amazing gardens called “Water”, “Earth”, “Fire” and “Air”.  The giant Eco gadget, once built, will be present on the waters of Seine, Thames, Volga, Danube, Escaut. We do not know when this incredible looking structure will be let lose, however we are looking forward to it. -via
