In 1893, British inventor Richard March Hoe patented the Darwin Feather Turbine, a unique wind turbine design inspired by the structure of a bird's wing.##Advantages over traditional wind turbinesHigher efficiency: The flexible feathers of the Darwin Feather Turbine allow it to generate more lift than traditional wind turbines, and this can lead to a higher conversion efficiency.Quiet operation: The flexible feathers of the Darwin Feather Turbine also help to reduce noise, which is a major concern for people who live near wind turbines.Versatility: The Darwin Feather Turbine can be adapted to a wide range of wind conditions, from low to high speeds.##Disadvantages over traditional wind turbinesComplexity: The turbine is more complex to manufacture and install than traditional wind turbines.Cost: The turbine is more expensive to manufacture than traditional wind turbines.I put glb 3d file to use in Powerpoint for presentation in Google Drivehttps://drive.google.com/drive/folders/1qQgDeRfYgob200PMYHRnV156mhLd3I59?usp=sharingi hope Grabcad will allow upload .glb file soon
