With the World Cup all set to begin on June 11 in South Africa, feast your eyes on this beautiful technological marvel: Cape Town Stadium. It will seat 69,070 fans, all of whom will no doubt scream at the top of their lungs at all the excitement on the field. But thanks to some clever engineering, the people living nearby will hear hardly a peep. This is South Africa’s first completely soundproof stadium.
The open-air stadium sits in Cape Town’s tiny Green Point neighborhood, where residents had raised concerns about crowd noise. To keep fans’ cheers to a minimum outside the building, a design team from the German engineering firm Schlaich Bergermann topped the structure with the world’s largest glass ceiling. The 398,265-square-foot roof consists of 9,000 half-inch-thick glass panels, arranged in a ring above the stands, and a Teflon and fiberglass mesh suspended below the glass. Together they reflect the crowd’s roar back onto the field and stands (potentially handing an advantage to the team with the loudest cheering section) to prevent noise from escaping through the roof’s central hole.
The roof will also protect fans from the Cape Town’s notoriously unpredictable weather. Such fickle weather is the result of wind kicked up by the nearby convergence of two major ocean currents: warm from the Indian Ocean and cold from the Atlantic. Combined with turbulent winds spilling off the city’s Table Mountain, gusts can reach more than 50 miles an hour. The roof’s concave shape deflects the wind and redirects it around the stadium. We’re totally psyched to watch live games in this awesome architectural wonder.

spectacular design… I love black and white color. I’ve been thinking what it would be like, if the exterior of the stadium is retro black and white. About the soundproof, It’s not the crowd cheering that the neighbours are worried about, it’s the blowing on their vuvu’s from begining till the end of the game.http://www.blackandwhitekitchen.com

modern, beautiful, hightech & sure very very expensive stadium. But hey.. I think as a poor country, south Africa has done a great great job as a host of word cup 2010. I hope the economic and social benefits created by the event will continue to benefit South African long after the visitors have left the country.

Being the host of the World Cup defenitely bring South Africa lots of money, much more than the stadium would cost.The World Cup in South Africa can be declared a success.It gives hope to the worldthat perhaps through football we can become better human beings. well done South Africa…

Combination of new technology solar [a very good likelihood, given recent advances in this area], wind [not a real big player, but no stone should be left unturned], geo-thermal [another very good source, under utilized and ignored to date], tidal [similar to wind, but more consistent], and the best non-player today that could help in the future, fusion power.
