DATACYCLE is a proposal for an interactive data collection installation for the future Bayfront Park that will over look the beautiful San Francisco Bay. The Bayfront Park will integrate a passive stormwater management system into the site. It is important, however, that we monitor that local water to be sure that pollutants are not running into the Bay. DATACYCLE will be a way for local park-goers to help monitor and engage with the health of the Bay. The DATACYCLES generate kinetic energy (the energy that it possesses due to its motion) that powers three sensors in the Bay. The three sensors in the Bay are (1) a water level sensor, (2) a pH sensor, and (3) a salinity sensor. That sensor data then gets sent back to a visual representation of the data that is in the park. The visual representation is seven water columns that are each seven feet tall. Each foot is represents a pH level between four and ten (the Bay’s pH level fluctuates between 6.5 and 8.5. The energy generated also powers pumps that pump the water into the water columns. As the water falls through the water columns the water also powers the sensors while the cycles are note being used. The whole design is a closed loop system.
