World's new largest wind turbine sweeps 10 football fields per spin

The China State Shipbuilding Corporation (CSSC) is upping the ante on offshore wind, announcing it's building the largest and most powerful wind turbine ever, making a peak 18 megawatts with an enormous 260-meter (853-ft) diameter on its three-bladed rotor.
It makes sense for a shipbuilding enterprise to get involved with this project; the blades of much smaller turbines are already a huge pain to transport, so building them right next to a dock in a facility designed for making, handling and launching enormous structures into the water eliminates a ton of problems as you attempt to go bigger.
Size is paramount when it comes to wind; the longer your blades, the larger the swept area and the more energy you can harvest from a single pole – and when it comes to offshore wind, the sea-bed foundations carry an outsized cost, so being able to generate more from fewer locations is a big deal.
The previous record-holder, the MingYang Smart Energy MySE 16.0-242 uses 118-m (387-ft) blades to sweep a 46,000-sq-m (495,140-sq-ft) area. CSSC Haizhuang's new H260-18MW turbine increases the blade length by 8.5%, to 128 m (420 ft), bumping up the swept area by 15.2% to 53,000 sq m (570,490 sq ft).
