South Korea’s floating ambition

Every summer, millions flock to a festival in the city of Boryeong, 200 km south of Seoul. The community offers visitors the chance to strip down and cake themselves in mud from the local tidal flats – a key geographic feature of the Korean Peninsula’s west coast. Another 50 km to the south lies the Saemangeum Seawall – the world’s longest manmade sea dyke, and the planned site of a massive 2.1 GW, state-backed floating PV installation.
