Twenty kilometers offshore from Fukushima is an experimental floating wind turbine. It is connected the the world’s first floating substation. If tests go well, 140 floating turbines, which are tethered to the ocean floor, will be installed, generating a gigawatt of power. This is the equal of some coal and nuclear plants.
The first prototype Fukushima wind turbine has already weathered an earthquake, small tsunami and typhoons in October—all before the turbine and substation are scheduled to begin full operation in November.
