the stadium is an enclosed dome with an adjacent outdoor natural-turf field that can be brought in for (soccar) games, and back out for sun and rain. When outside, the grass pitch is surrounded by an area of gently sloped grass, which serves as an outdoor arena.
Technology / how it works: the pitch sits on a layer of sand above heating and draining pipes supported by a concrete deck on a steel fame. The deck is equipped with air blowers (which can create a pneumatic force of 1.09 atm), 34 wheels and turning devices – thus, when the blowers are on it becomes a “hover-craft”, and reduces the weight of the 8300ton pitch by 90%. Emittors embedded in the floor guide the pitch into the dome, and axles rise up to guide the turning (the pitch has to 90 degrees within the dome).
… multifunctional and innovative stadium that can transform itself from a football (soccer) stadium into a baseball park… The system is as simple as it is sophisticated. Raised on a pneumatic system, the playing field is made to rotate and pass through a mechanized 90 meter opening of two moving walls. The field can either be placed in an artificial basin below the stadium or transported outside where the grass can grow naturally. The whole transformation process takes only 5 hours to complete.
