Digital cloud plan for city skies By Jonathan Fildes Technology reporter, BBC News The inflatable elements of the building would sit on top of thin, lightweight towers A giant "digital cloud" that would "float" above London's skyline has been outlined by an international team of architects, artists and engineers. The construction would include 120m- (400ft-) tall mesh towers and a series of interconnected plastic bubbles that can be used to display images and data. The Cloud, as it is known, would also be used an observation deck and park. The unconventional structure was originally envisaged as a centre piece of the city's Olympic village. The building draws inspiration from the work of Tomas Saraceno Its designers plan to raise the funds to build it by asking for micro-donations from millions of people. "It's really about people coming together to raise the Cloud," Carlo Ratti, one of the architects behind the design from the Massachusetts Institute of Technology (MIT) told BBC News. "We can build our Cloud with £5m or £50m. The flexibility of the structural system will allow us to tune the size of the Cloud to the level of funding that is reached." The size of the structure will evolve depending on the number of contributions, he said. Paola Antonelli, senior curator of architecture and design at the Museum of Modern Art in New York who has seen the design described it as a "sculptural spectacle" and "a celebration of technology". 'Data streams' The Cloud was shortlisted in a competition set up by London Mayor Boris Johnson. The mayor has committed to build a tourist attraction in the Olympic Park "with a legacy for the east end [of London]". Other finalists are thought to include the former Turner prize winner Anish Kapoor and Antony Gormley, the designer of the Angel of the North. The mayor is still in the "process of deciding" which design will be commissioned, according to a spokesperson. However, the team, which also includes the writer Umberto Eco and engineers from Arup, has decided to push ahead and publish details of its design. The structure draws on work by artist Tomas Saraceno, a German-based designer who has previously shown off huge inflatable sculptures. It is envisaged that the spheres would be made of a plastic known as Ethylene tetrafluoroethylene (ETFE), the material used to build the Beijing Aquatic Centre. The different spheres would act as structural elements, habitable spaces, decoration and LCD screens on which data could be projected. "We could provide a custom feed of… searches made by Londoners during the Olympics to give a real time 'barometer' of the city's interests and mood," said Google, one of the supporters of the project, which has also offered to provide the information feeds. The team also envisage projecting weather information, spectator numbers, race results or even images of the Olympic Torch on to the building. Ramps, stairs and lifts would carry people to the top of the structure to look out over the city. 'Zero power' The inflatable elements of the building would sit on top of slender, lightweight towers, stabilised by a net of metal cables. Damping technology, similar to that used in Japanese skyscrapers to resist earthquakes, would prevent the towers being buffeted by the wind. The Killesberg Tower in Germany is built using similar principles "Many tall towers have preceded this, but our achievement is the high degree of transparency, the minimal use of material and the vast volume created by the spheres," said professor Joerg Schleich, the structural engineer behind the towers. Professor Schleich was responsible for the Olympic Stadium in Munich as well as numerous lightweight towers built to the same design as the Cloud. The structure would also be used to harvest all the energy it produces according to Professor Ratti. "It would be a zero power cloud," he said. As well as solar cells on the ground and inside some of the spheres, the lifts would use regenerative braking, similar to that in some hybrid cars. That way, the designers say, potential energy from visitors to the top of the tower can be harnessed into useful electricity. The team have launched a fundraising website called raisethecloud.org and are now looking for a site for the tower. Google has already offered to provide free advertising for the so-called "cloud-raising" effort. The firm has offered a sponsored link at the top of the page advertising a "£1 for 1 pixel" concept to people who search for terms relevant to London 2012. "It will be a monument to crowd-sourcing," said Professor Ratti.
