The invention won the Innovation category of the Hong Kong Student Science Project competition. The awards marked the start of the three-month Innovation Festival, aimed at raising awareness of the need for new ideas in Hong Kong. The competition attracted 121 entries from 70 schools. Winning projects will be displayed at the Innovation Expo in the Hong Kong Convention and Exhibition Centre between September 20 and October 2. A team from Carmel Pak U Secondary School took top spot in the competition's Investigation category for their work on an alternative, energy-saving form of fuel. Lau Tsz-kin, 17, of MKMCF Ma Chan Duen Hey Memorial College, said: 'We have discovered many new things from the competition. We became addicted to science.'
