Such turbines are an optimized class of wind turbines that use a diffuser to accelerate and direct airflow onto a wind turbine rotor, to drive it for higher RPM and power output rather than without the diffuser. This power output is typically rated in terms of power. . These breakthroughs offer valuable insights for the future of small wind turbine design, providing a pathway to more efficient, economically feasible solutions. INTRODUCTION Renewable technologies are considered clean sources of energy, and optimal use of these resources minimizes environmental. . In this study, we proposed the introduction of winglets and wind collectors (used in aircraft wings) into straight-wing vertical-axis wind turbines to improve their power generation efficiency. Field tests were conducted to confirm the effectiveness of the proposed method.
