The Solar Updraft Tower, developed by the international civic engineering firm schlaich bergermann and partners, is a solar chimney power plant for sun-rich regions of the earth, that uses practically no renewable resources such as oil, gas, or coal. In the Galerie Aedes Berlin, in the smallest of spaces, the appearance and technology of this power plant are demonstrated: in the middle of a room covered in sand, with the help of a model and a terminal, which explain the functioning of the power plant. Moniteurs, in close cooperation with the client, developed a CD presentation using a self-explanatory flash animated interface and a clear navigational structure.
