I’m interested in small wind Turbines(200W- 5kW),and wanted to know difference between Vertical and Propeller blades.Where I can find information about it ?Thank you.
Centre for Alternative Technology run very good courses and have some online info sheets
vertical means you can put all your machinery on the ground for easy maintenance etc. but they are not reliably self-starting, and near the ground the wind is more turbulent and not as strong.
hence most comercial wind turbines are "propeller" type.
