Applying Sci-fi

Hubless wheels, or a wheel without a center are often something seen in science fiction and  future concept vehicles.


While they look great, there are a number of issues in practicality and even just getting a prototype to function.  However, the hubless wheel design is not entirely in vain. In fact, it has even won design awards.


When used as a pizza cutter the hubless wheel is beautiful, functional and totally unique. What else can be designed, by taking sci-fi concepts, and finding a practical application?
