Initiated by PolyU students, from 11 to 12 September, more than 1,500 members from the University community successively pedalled on static bikes day and night for 24 hours to generate electricity and promote renewable energy, sustainable development and healthy lifestyle. Funded by the University Grants Committee, this "Enlighten" project finally generated a total of 31,399.31 watt-hour of energy to lighten up 50 LED lights on campus.
