Vertical-axis wind turbines: what makes them better?

You may have seen this photo online recently of EDF’s floating offshore vertical-axis wind turbine (VAWT) called “Vertiwind.” It has a nameplate capacity of two megawatts. The Vertiwind will be part of EDF-EN’s offshore wind farm project called Inflow, which the European Commission is helping fund. The strange design piqued my curiosity about VAWTs. Why…
