Eco Factor: Sustainable streetlight powered by renewable wind energy.
The streetlight is an essential public facility and plays an indispensable role for safety and townscape of the city. However, a huge amount of electricity is consumed to light up the street lights, so it can be a burden for the modern city, causing insufficient energy supply. Industrial designer Woojin Kim is proposing a sustainable lighting solution that doubles as a bench to be utilized as a public facility. Dubbed Double Life, the concept streetlight design is powered by generator-condenser unit (a concept device that can generate and store electricity at the same time) with a wind turbine to utilize renewable wind energy.
The Double Life uses vertical axis wind-turbine for maximum efficiency of generating electricity and reducing visual resistance. LEDs are used for the lamp to minimize energy consumption and for its semi-permanent lifetime. It is settled under the plate which is used as the bench seat. Onboard sensors detect sunshine, enabling the motor to rotate the screw pillar to lower the bench plate down through the spiral structure. After the sun is set, screw pillar moves the plate up to light position. The screw structure is designed to move very slowly over time to provide safe operation and to prevent any accidents for the bench users.
