Storyline: World's most powerful direct-drive floating wind turbine unveiled in China [Voice_over] The world's most powerful direct-drive floating wind turbine has rolled off the production line in China - marking a leap forward in offshore wind turbine technology. The newly-complete 17-megawatt turbine, with a record-breaking 262-meter rotor diameter, will generate 68 million kilowatt-hours of electricity annually, enough to power approximately 40,000 households. The engineering marvel can withstand extreme marine conditions, like 24 meter waves and wind gusts of up to 190 kilometers per hour. Even when the floating platform tilts at extreme angles, it can maintain continuous power generation. Experts from the turbine's developer, China Huaneng Group, say the floating turbine technology is expected to unlock the potential of deep-water wind energy. [Sound_bite] Liu Xin, director, offshore wind division, China Huaneng Clean Energy Research Institute： "This type of floating wind turbines is specifically designed for deep-sea environments and can be deployed in waters of over 50 meters deep for offshore wind energy development." [Voice_over] Officials say now the turbine will undergo real-world testing in waters off south China's Guangdong Province. Recent data from the Global Wind Energy Council shows that the global installed capacity of floating wind power was 278 megawatts at the end last year, with Norway, the UK, China and France as the world's top four markets.
