A proposal for a skyscraper that grows biodiesel-emitting algae took 2nd place in a competition to design the 300m tall Taiwan Tower in Taichung.
From the architect's statement:
"The entire tower is inspired by the creation of energy. Living energy which must be Visible living energy SYMBOLISING THE VISIBLE ENERGY, ENTERPRISE AND INVENTIVE OPTIMISM OF THE TAIWANESE PEOPLE. The droplets are the primary elements of this process. Their activity, presence and form resonate throughout the scheme.
Much of the tower is open to the public to view the processes at close quarters. Even from the lifts, the daily state of vegetable husbandry will be visible. A variety of different arrangements of plantation and localized environment are distributed over its length. The principal purpose of the tower is to CREATE ALGAE.
When watered and filtered the algae create BIOMASS used as food for fish and plants and for making paper and BIOFUEL for powering engines."
