The ambition behind NL Architects' proposal for the Taiwan Tower Competition was to create a 300-meter high freestanding tower with sightseeing and recreational functions that will serve as a 'model green building'. By simply combining the two typologies of windmill and observation tower, their design, 'Tower of Power', aspires to change the ‘content’ of the new generation of tourist towers and at the same time, the appearance of future wind energy generators. Instead of being yet another ‘empty’ icon, it actually is a usable object. Other than the required functionality as sightseeing tower and telecommunication base, it is also an environmentally friendly power plant. NL Architects' tower raises questions on how power plants of the future can be turned into objects of beauty.
