CLAIMS: 1. A vertical axis windmill or turbine having a rotor carrying a plurality of pivotted blades the pitch of which can be varied by the force of the wind or other working fluid characterised in that the blades are interconnected by means of links radiating from a central junction which is displaceable through a controlled range from the axis of the rotor, the outer end of each link being ...

Vertical windmills aren’t such a recent concept. In fact, despite that we are accustomed to seeing horizontal axis windmills, the first windmills invented were the vertical ones. The first functional types were invented in the 9th century, but their design has changed very much over the years in order to get a higher efficiency from them.

Wind costs follow what economists call a learning curve: For every doubling of wind production, the cost goes down by a fixed percentage. For example, if the price of electricity from wind is 10 cents per kilowatt-hour with a given number of wind farms, a 10 percent "learning rate" means that wind electricity would cost 10 percent less, or 9 cents per kilowatt-hour, if one doubles the ...

The propeller produces airflow, which turns helically around the fuselage of the aircraft. For conventional aircraft this means that there's a kind of "wind" pushing on the side of the vertical stabilizer, which causes some yaw tendency. All of these are corrected with a bit of right trim in the ailerons and rudder, or compensated for manually.

Vertical Axis Wind Turbine (VAWT) A wind turbine cannot be a wind turbine unless it has few blades. Likewise, the horizontal axis turbines, vertical axis ones also have a set of blades. But instead of spinning horizontally, they spin vertically. So, the rotational axis of a VAWT is in the vertical direction, and that's why it got such a name.

How a Wind Turbine Works. A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates ...
