Some sources of power work better than others in different geographic locations, which is why it is essential to consider these crucial points before finalizing an installation effort. It reduces transmission losses and the required transmission infrastructure to deliver the power, increasing costs. It seems that the guide blades on the bottom of the duct would allow little more thrust to be extracted from the vortex the prop generates by redirecting the air flow. The blades of wind turbines create a "whooshing" sound as they turn and can be heard from a long distance away. The ducted turbine has the ability to accelerate the air flow through a converging intake thereby increasing the power that can be extracted from the air flow. That means utility suppliers must have access to alternative sources of power or have an energy reserve available to offer a stable base supply of power. Farmers struggle to create a profit in some countries, but wind farm lease income is a reliable revenue stream. Bats and birds who have migratory paths or habitats in proximity to this technology could get injured or killed with a blade strike. rev2023.3.3.43278.
