Introduction to Vertical Axis Wind Machines
Wind energy is growing more economical and reliable. Vertical axis machines can help meet smaller, local needs for communities with limited resources. These include pumping water, grinding grain, powering workshops and in some cases, generating electricity. Learn about the two main types of vertical axis wind machines in this article: The lift type (eggbeater, helical and h-rotor) The Darrieus vertical axis wind turbines often has two or three thin, curved blades, depending on the model. These turn at higher speeds suitable for generating electricity but require much greater skill in design and engineering. The h-type is simply vertical blades. The … Continue reading
