This Italian concept clearly has an futurist practical side: no more loss of water! use it to grow plants or food altogether and herbs (basil, chives, … !)
The two opposing tanks contain clay balls on top and coconut fibers below, these will act as a regulator of the water environment of the plant in addition to assuming a role of cleaner base of the rack, to be kept clean at all times.
your sinks should ideally be near a window so that light enters in sufficient quantity to make the plant grow.
Really nice, where do we buy it …? For now it is not possible because it is just a concept (Fluidity) but it might give ideas to build one yourself (using a 3D printer).
