A vertical axis wind turbine has its axis perpendicular to the wind streamlines and vertical to the ground. A more general term that includes this option is "transverse axis wind turbine" or "crossflow wind turbine." For example, the original Darrieus patent, US Patent 1835018, includes both options.

UltraHigh Efficiency Vertical Axis Wind Turbine Technology Climate Technology Centre & Network. Background: With a recent focus on renewable energy wind turbines have become a popular method for harvesting unused energy and providing clean energy to customers. There are two types of wind turbines that are commonly used: horizontal axis
Savonius windmill. This is an experimental vertical axis windmill and electrical generator, which in a fair breeze, easily provides 5V at a few 100mA''s. I know that the following details are a bit scanty but I wanted to get something up on the web site to inspire people to get experimenting.

Unconventional wind turbines are those that differ significantly from the most common types in use.. As of 2012, the most common type of wind turbine is the threebladed upwind horizontalaxis wind turbine (HAWT), where the turbine rotor is at the front of the nacelle and facing the wind upstream of its supporting turbine tower.A second major unit type is the verticalaxis wind turbine (VAWT
DIY VAWT Vertical Axis Wind Turbine. In this project, we will build a small DIY VAWT, Vertical Axis Wind Turbine. We are not expecting to get much over 50 watts of production, though it would be fairly simple to double the size of the blade area to increase power.
These Creative Wind Turbines Will Have You Rethinking What You Know About Wind Power Wind turbines don''t have to all look the same. Here are some that are
Vertical axis wind turbines aren''t replacing horizontal axis offshore turbines February 18, 2014, by Mike Barnard. Over the past few months, an interesting wrinkle on the verticalaxiswindturbinesarebetter mythology has surfaced: that they are superior offshore and that many countries are investing heavily in
10 Wind Turbines That Push the Limits of Design. What It Is /// WePOWER is a verticalaxis wind turbine that operates quietly and performs well in lowspeed winds.
Raum Energy Inc. Raum Energy Inc. provides the complete wind energy system turbine, tower, gridtie inverter or battery charger. The turbines are designed from the ground up to supplement grid electricity and have the lowest payback period of all gridtie turbines in their class.

A NEW DEVELOPMENT ON VERTICALAXIS WIND TURBINES: THE DIRECTIONAL WIND FLOW AND PROTECTIVE SCREENS. In recent years wind turbines have become an increasingly important source of renewable energy and are being used by many countries as part of a strategy to reduce reliance on fossil fuels.
grassland and 0. 40 for city centre/urban For offshore sites, steep proﬁles of wind speed for the vertical. direction usually necessitate lower hub heights, with minima offshore wind
Governing is automatic: of yaw by tail vane, and of torque by setting the wheel offcentre with respect to the vertical yaw axis. Thus, as the wind increases the mill turns on its vertical axis, reducing the effective area and therefore the speed. The most important use of the windmill was for grinding grain.

Savonius wind turbines are a type of verticalaxis wind turbine (VAWT), used for converting the force of the wind into torque on a rotating shaft.The turbine consists of a number of aerofoils, usually—but not always—vertically mounted on a rotating shaft or framework, either ground stationed or tethered in airborne systems.

The older mill was a post mill, which means it is a mill whose body mounted on a vertical post must be rotated so that its blades face the wind. The new mill, which is a tower mill, allowed for only the cap or upper part of the mill to be rotated while the base stayed put, a more stable and efficient setup.
