Planet's largest wind turbine record broken again at 26-MW
China, the undisputed global leader in wind energy, has just set another world record for the world's tallest and highest-capacity offshore wind turbine, taller than the Eiffel Tower, The Chrysler Building, and longer than the longest US aircraft carrier.
Dongfang Electric Corporation (DEC) is building these massive 1,115-foot-tall (340-m), 26-MW wind turbines at its factory in Fuzhou, Fujian Province.

The nacelle hub height sits at 607 ft (185 m), while the blade diameter is a whopping 1,107 ft (310 m). It has a blade swept area of 812,424 square feet (75,477 sq m). Do you know what else has about that much wingspan? Twelve Boeing 747s. You'd need an area the size of 14 NFL football fields, or a decent city block, to lay it down. It's a bit big.
Even with such a large profile, DEC says its offshore turbines are resistant to typhoons and corrosion. It was engineered with a "dual anti-typhoon design" to allow it to withstand extreme typhoons, but details are scarce as to what the design entails.
According to Donfang, "it has the ability to withstand a Category 17 super typhoon." That entails winds of up to 137 mph (220 km/h), about the same as a Category 4 hurricane. UNICEF describes these super typhoons as having "extremely destructive power, sinking large ships, potentially causing severe damage and serious flooding." So it's certainly impressive if these whopping airfoils can survive such a maelstrom.
