Dynamic Tower, designed by architect David Fisher
The Dynamic Tower is a planned 420m, 80 floor, 'moving' sky scrapper in Dubai.
Each floor will be able to rotate independently, which will result in a constantly changing shape of the tower, each floor will rotate a maximum of 6 meters per minutes and one full rotation will take 90mins. It will be the worlds first prefabricated skyscraper with 40 factory build modules for each floor. 90% of the tower will be built in a factory and shipped to site.
The entire tower will be powered from wind turbines and solar panels. Enough surplus electricity should be produced to power 5 other similar sized buildings in the vicinity. The turbines will be located between each of the rotating floors and can generate up to 1,200,000 kilowatt-hours of energy. The solar panels will be located on the roof and the top of each floor.
Whalepower
The company, WhalePower, has redesigned the typically smooth blades on a turbine, adding a series of ridges, based on tubercles, the bumps on humpback whale fins. The company says this new blade design could increase annual electrical production for existing wind farms by 20 percent.
Humpback whales tilt their fins at steep angles to achieve better lift in the water. Too much tilt, however, has the opposite effect--a loss of lift, called stalling. Tubercles prevent stalling, allowing for more aggressive fin tilts. WhalePower's tubercle-like structures on the turbine blades allow the blades to have steeper angles--without causing stalling or creating too much drag. During low wind, blades with steeper angles can theoretically generate significantly more power.
Wind Turbine Viaduct
A new bridge concept incorporates wind and solar energy into its design, generating 40 million kilowatt-hours per year. The Solar Wind concept would use the space between an existing viaduct in southern Italy to install 26 wind turbines, which designers Francesco Colarossi, Giovanna Saracino and Luisa Saracino say could provide 36 million kilowatt hours of electricity every year.
