Energy Source Show

The voyage through the pavilion reaches its climax – the Energy Source show. The show can be experienced by 600 people at a time and it ends with them becoming part of the show themselves.

The Energy Source is where the energy is generated to bring a city to life. It is the heart of balancity and the highlight of the German Pavilion. The visitors play a “leading role”, controlling what happens. Through an impressive community experience, they discover that together they can – quite literally – get things moving.   

Visitors enter an awe-inspiring, cone-shaped room with dramatic choreographed lighting. From a gallery, they can see the main attraction – a sphere, three metres in diameter and fitted with thousands of LEDs. Pictures, colours and shapes appear on its surface, showing impulses from Germany for EXPO 2010 – ideas that Germany is contributing to the quest for a “Better City – Better Life”.

The sphere is set in motion, and the impulses triggered, by the audience, directed by Yanyan and Jens. They have already been accompanying the visitors on their journey through balancity in virtual form and now they appear in the flesh. The approximately 600 spectators are divided into two groups. The two groups quickly realise that they can set the sphere swinging by making movements and shouting loudly. The sphere begins to swing back and forth. The further it swings, the more intensive the colours become. The sphere’s energy is reflected throughout the room – on the balustrades, the walls, the ceiling and the floor.

The swinging initiated by the audience picks up speed and momentum and the sphere starts to move in a circular motion. Lots of different images of Germany and balancity race past the spectators’ eyes. Then the sphere comes to a halt and there’s silence. The room is bathed in green light and a pleasant, natural atmosphere sets in under a blue sky. From a globe, a seed grows, slowly turning into a flower – a symbol of new life.  The visitors leave the German Pavilion “positively charged” with the energy they have generated together. As they continue through the German Pavilion and the EXPO site, they take new, impressive, pleasant images of Germany with them.
