In 2010, Vishnu Jayaprakash, then a Chennai Class XII student of Chettinad Vidyashram demonstrated a microbial fuel cell that runs on cow dung and inexpensive graphite electrodes. The minor planet named after him is called 25620 Jayaprakash. He aimed to reduce power costs for India’s 700,000 villages. Today, he has done extensive research on renewable energy technologies, and is now focussing on Microbial Fuel Cell (MFC) technology.
