Chicago Solar Tower
Solar architecture doesn't just have to fill the skylines of foreign cities; it could also soon be coming to North America. Check out this design for a Solar Tower in Chicago by Zoka Zola Architects. This skyscraper is almost completely shielded by sun-tracking solar panels, which rotate like sunflowers to follow the sun throughout the day.
The panels are carefully positioned to provide shade for the building's floors but not to obstruct the view. According to its designers, this tower's "cosmo-bio-logical skin" could have the power to produce "new and intensified experiences and awareness" for the citizens of Chicago.
