This video shows workers casting concrete
for the gravity foundations of the Middelgrunden wind turbine
park off the coast of Copenhagen. (The video runs for 1 minute
and 10 seconds, 1087 K, soundtrack included, free QuickTime
plugin required).These foundations are a hybrid between steel
and concrete foundations since concrete is only used as the ballast
in the bottom section (the cylindrical 17 m slab).
