The Most Efficient Wind Turbine Design by Professor Yuji Ohya, (Kyushu University) this wind power system called the wind-lens turbine was completed at the Ito Campus. While providing power to the campus, tests to increase the scale of the system will be conducted.

New wind turbine system that consists of a diffuser shroud with a broad - ring brim at the exit periphery and a wind turbine inside it. The shrouded wind turbine with a   brimmed diffuser has demonstrated power  augmentation for a given turbine diameter and wind speed by a factor of about 2 - 5 compared with a bare wind turbine.This is because a low - pressure region due to a strong vortex formation behind the broad brim draws more mass flow to the wind turbine inside the diffuser shroud.
