The Energy Source is where the energy a city needs to live originates. It is the heart of balancity and the ultimate highlight of the German Pavilion, the source of power and zest for life. But, in fact, the visitors themselves are the source of the energy. Their ideas, thoughts and impetus are brought into balance, thus creating a balanced city.

The visitors enter an awesome, energy-laden room filled with an exciting light choreography. Then they spread out across three galleries from where they can see the room’s focal point: a sphere. The sphere has a diameter of three metres and its surface is covered with around 400,000 LEDs. During the seven-minute show, images, colours and shapes appear on it, symbolising German ideas related to the EXPO theme of “Better City, Better Life”.

Jens and Yanyan, who have been accompanying the visitors on their journey through the pavilion in virtual form so far, now appear in person. On kickboards, they circle around on the second-level gallery and encourage the visitors to get involved in the action. With Jens’ and Yanyan’s help, the visitors quickly realise that they can influence and bring to life the sphere and the entire room by shouting. The sphere begins to swing back and forth. It absorbs the audience’s energy, flies higher and higher, faster and faster. At its highest point, it starts to
move in circles.
