vincent callebaut's 'physalia' amphibious garden to clean waterways

vincent callebaut architectures has designed ‘physalia’, an architectural prototype of an amphibious garden — a floating agora which is meant to clean waterways in europe. the project aims to meet the needs of maintaining a sustainable management of water resources. the roof of the structure contains a double pneumatic membrane chiseled with smooth photovoltaic solar cells.

under the hull, hydro-turbines transform the energy of the fluvial stream into hydro-electricity. the surface of the vessel is made from an aluminum covering which covers the multi-hull steel structure. the silver-plated dress is covered by a TiO2 layer of anatase shapes that when reacting to ultraviolet rays, reduces water pollution. in addition to being a self-cleaning vessel, it can absorb and recycle by photo-catalytic effect. physalia is crossed in its double hull by a hydraulic network that filters the fluvial water and purifies it biologically thanks to its planted roof. the interior is divided into four thematic gardens: water, fire, earth, air.
