Electricity sparks new life into Indonesia’s corals

(Discovery): A weak, harmless voltage run through metallic structures underwater is reviving near-dead reefs. Cyanide fishing and rising water temperatures had decimated corals off Bali until a diver inspired by a German scientist's pioneering work onorganic architecture helped develop a project now replicated worldwide. Based on ""Biorock" technology, it is implemented in 20 countries, mainly in Southeast Asia, the Caribbean, Indian Ocean and Pacific. In the turquoise waters of Pemuteran off the north coast of Bali where the project was launched in 2000, a metal frame known as "the crab" is covered with huge corals in shimmering colours where hundreds of fish have made their homes.
