Ecosistema Urbano’s “Energy carousel” is an inventive, educative and multi-age friendly playful object. A play structure consisting of a tensegrity structure formed with ropes and textiles. The kinetic energy that is released by the children’s movement is stored in a battery and supplied after to light up the structure.Ecosistema Urbano has designed this play structure with two particular focuses in mind. The first is to promote education through play. We believe that teaching children about alternative methods for generating electrical power with their own physical experiences, sends a subtle message about the potential for creative and a more sustainable approach to urbanism.
