To learn about the geometry of the Twisted Savonius wind turbine, please choose an option from below. The dynamic documentation contains ten web pages with interactive diagrams, animated images, and videos explaining the Twisted Savonius geometry modeling project. The Static PDF contains the same work, in one PDF file without the interactive diagrams, animations, or videos. Finally, the media library contains a collection of all of the interactive diagrams, animations and videos, and the abstract is a brief summary of the project. If you want to build a model of the Twisted Savonius, skip to the last page of the dynamic documentation.
