Innovative ways to float skyscraper-sized wind turbines (mena-forum.com)
Record-tall Wind Turbine Towers with 3D-printed Concrete Bases were in the news a few years back. Today, here are six innovative ways to float skyscraper-sized wind turbines. These enormous turbines can reach up to 240m tall—about the size of a skyscraper. Since they are so tall, strong winds far above the sea surface tend to cause the turbine to tilt, so platform designs focus on minimising this tilt while still being cost-competitive with other forms of energy.
