Aerospace engineers are developing dual-rotor technology to improve the energy harvest of wind turbines. The idea to look for better performance by adding a second rotor to wind turbines came from a previous study. The researchers used wind tunnel tests to see how hills, valleys and the placement of turbines affected the productivity of onshore wind farms.
