MIT SOFT Rockers are clean energy charging stations that double as rocking outdoor lounge furniture. Unlike conventional ‘hard’ urban infrastructure, The SOFT Rocker leverages its environment in a dynamic manner by using the human power of balance to create an interactive 1.5 axis 35 watt solar tracking system. Soft power electronics designed for this project charge the 12 ampere-hour battery and store solar energy harvested during the day. You can even put your body weight in play with an interactive, real-time energy harvesting feedback loop that senses how you orient the rocker to the sun. Charge or run any USB device from speakers to cell phones and bring your friends to enjoy cool lighting loops at night for social gatherings.
