2. Seamlessly integrating a modern design/technology, typically seen in rural areas, into an urban environment. + = ??

3. Either the hanging, or resting design could have been used Design meant to remain small while catching more wind (multiple turbines) The “Diner” Look

4. Compares traditional open face turbine to confined design Refined “Diner” Design Integrated for Building Type

5. “Pyramid” Design Building Top Ideas Rather than using only one edge of the roof, takes advantage of entire space

6. “Mayan” Design Modification of original Pyramid Design. Implements flat roof rather than pitched.
