At COP17 in Durban this month, Greenpeace launched it's larger-than-life wind chime, made of bamboo pieces that each held the name (or names) of South Africans who are calling for a renewable energy to be used more.
Every time the wind blew through the chimes, Durban's North Beach could hear the melodic sound of South African's calling for an energy revolution.
