Although these conceptual designs may seem like science fiction, they are actually part of a plan for a new landmark in Taichung, Taiwan. The tower, expected to be completed in two years, will stand 1,000 feet tall and will use wind turbines and solar cells as part of its energy-efficient design. Perhaps the most interesting and distinctive features of this building are the “Floating Observatories” that float up and down a vertical track on the outside of the building. These blimp-like structures can carry up to 80 people and are sustained by helium balloons! For more information, click here.
