IwamotoScott's Grand Prize winning scheme for the City of the Future invited design competition, sponsored by the History Channel, IBM and Infiniti. Hydro-Net addresses the brief of re-thinking the city of San Francisco 100 years into the future, and proposes a new underground infrastructural network for the distribution of alternative fuel, power and transportation. Baylands predicted to be flooded with rising waters of global climate change are proposed as new aqua-culture zones with high rise housing towers, facilitating the growth of algae to be used in the production of hydrogen fuel. Constructed by self-drilling robots using carbon nano-tube construction, Hydro-Net directs the flow of higher-speed traffic of clean-burning hydrogen fueled hover cars. Feeding into the network are fresh water and geothermal energy harvesting civic structures, called Fog Flowers and Geothermal Mushrooms. As such, Hydro-Net also taps into reserves of fresh water and energy harvested both above and beneath the city. The project was carried out in one week with the help of a team of students and graduates from both CCA and UC Berkeley.
