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 "cross-flow wind turbine." For example, the original Darrieus patent, US Patent 1835018, includes both options.

A wind turbine, or alternatively referred to as a wind energy converter, is a device that converts the wind's kinetic energy into electrical energy.. Wind turbines are manufactured in a wide range of vertical and horizontal axis. The smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic warning signs.

The design of the individual blades also affects the overall design of the rotor. Rotor blades take the energy out of the wind; they "capture" the wind and convert its kinetic energy into the rotation of the hub. there are two types of blades use in VAWT . Drage force type blades ( savonius wind turbine)

Because our VAWT produces energy when other turbines most are stationary due to LOW or HIGH wind conditions and it produces more torque. Most Designs normally get lift from one blade and drag from other blades. Our design takes lift from multiple blades and minimizes drag from the none performing blades.
