This nearly 500-foot tall wind turbine is built to withstand typhoon-level winds. The rotor diameter is 853 feet, which is the new record, and can generate 16 megawatts of power. 

A team from GE in the United States is building a turbine that can generate 18 megawatts of wind power. 

Now this is a competition between the two economic giants that I can really get behind. More sustainable energy sources benefits everyone.
