The 2011 Skyscraper Competition  is an endeavor to revolutionize efforts, vision and passion that  architects put into building our future infrastructure. The projects  have been adjudged for their use of new technologies, materials,  programs, aesthetics and spatial organizations, along with studies on  globalization, flexibility, adaptability, and the digital revolution.  Hosted by the eVolo Magazine,  the focus of the jury has been to pick out those ideas that understand  architecture and its relationship with the natural and built  environments.
First Place: LO2P: Delhi Recycling Center by Atelier CMJN, Julien Combes & Gaël Brulé

LO2P  skyscraper is destined for New Delhi, the highly polluted capital city  of India. Reminding you of the London Eye, this Ferris wheel like  structure is built using old cars recycled for sourcing building  material for the new structure. The surrounding air will be purified  through a series of large-scale greenhouses that serve as filters.  Another set of rotating filters capture the suspended particles in the  air while the waste heat and carbon dioxide from the recycling center  are used to grow plants that in turn produce bio-fuels.
Second Place: Flat Tower by Yoann Mescam, Paul-Eric Schirr-Bonnans & Xavier Schirr-Bonnans

The  Flat Tower is a new high-density typology that features a medium-height  dome structure with perforated cell-like skylights. The dome’s large  surface area is the ideal location to harvest solar energy and collect  rainwater. The structure houses community recreational facilities at the  ground level, residential and office are located at the upper cells. An  automated transportation system connects all the units, which are  different shapes according to their program. This project has been  designed for the city of Rennes, France, in an old industrial area but  can be adapted to fit any location.
Third Place: Re-imagining the Hoover Dam by Yheu-Shen Chua

At  the present moment one can visit the Hoover Dam and partake amenities  like a viewing platform, a bridge, and a gallery. But the problem is  that they are located at different areas of the site.

Rhizome Tower: A Thousand Underground Plateaus by Enrico Tognoni, Federico Tinti & Davide Mariani

The  Rhizome Tower is an underground city and something out of a surreal  fantasy! It’s essentially a ‘Groundscraper’ that harvests natural  resources above and below ground while creating a new living typology.  The idea is to cultivate a self-sufficient underground city and maybe  even develop a nation or two in the process! The entire setup is divided  into 4 layers that is organized around a central core. The first layer  is above the surface and contains the recreational, and food production  facilities, with agriculture fields, farms, and glasshouses. The entire  façade is covered with photovoltaic cells to harvest solar energy and  specific locations are also equipped with wind turbines. The second  layer, approximately 60 levels, is the residential part, with a diverse  range of living quarters according to family sizes. The third and fourth  layers are used as offices, and service areas with the deepest part of  the project dedicated to the study and harvest of geothermal energy.

Chernobyl Skyscrapers Network by Mengni Zhang

Chernobyl Skyscrapers Network is the reconstruction of a post apocalyptic environment around the Chernobyl power plant, Ukraine.
White Cloud Skyscraper by Adrian Vincent Kumar, Yun Kong Sung

The  White Cloud Project is an air purification network of skyscrapers and  is shaped as inverted buildings with ample public space at its base and  residence and offices clustered on top. A fine membrane that cleans the  air through an ingenious filtering process covers the structure. The air  particles are trapped by the cloth-like structure and washed away by a  constant mist. At the same time the collected dust is transported  through a secondary branching system to a brick factory on the bottom.
Coalesce Skyscraper by Justin Oh

The  final height of this skyscraper has not yet been decided, as perpetual  development of the project has continued for more than twenty years!  What is evident is that over the years, the distinct architectural style  of each year, is reflected in each developing layer.
