Tree Shaped Wind Turbines to be Installed in Paris
There are two classes of windmill, horizontal axis and vertical axis. The vertical axis design was popular during the early development of the windmill. However, its inefficiency of operation led to the development of the numerous horizontal axis designs.

Vertical axis wind turbines, as shortened to VAWTs, have the main rotor shaft arranged vertically. The main advantage of this arrangement is that the wind turbine does not need to be pointed into the wind. This is an advantage on sites where the wind direction is highly variable or has turbulent winds.
ABSTRACT A vertical axis wind turbine is supported by a frame held in place by an encircling series of crescent-shaped tubular deflector vanes. The vanes widen towards the turbine core, concentrating the wind.
This system can be seen as a vertical axis wind turbine driven by forces which come from tethered aircraft. There is no prototype under development, but the concept has been studied in a simulation  showing that 100 kites with 500 m 2 area could generate 1000 MW of average power in a wind with speed of 12 m/s.

What's Good and Bad about Wind Energy - Kids Discover
2018-05-29· Watch video· To build a wind turbine, you'll first need to assemble a spindle and spokes for the turbine. Then, mount magnet rotors on the turbine and weld the spindle flange to the tower. Once you've done that, mount the main assembly of the turbine on the tower and secure it into place. Finally, attach the electrical components of the turbine to the rest of the assembly and connect it to a …
A French company called New Wind is installing tree-shaped wind turbines at the Place de la Concorde in Paris, France. The company's founder, Jérôme Michaud-Larivière came up with the idea while in a Paris square, when he "saw the leaves tremble when there was not a breath of air."
Airborne Wind Energy Systems: A review of the technologies
Wind turbines are of two types: Horizontal Axis and Vertical Axis. In a horizontal axis one, the main rotor shaft and electrical generator is placed at the top of the tower and it must be pointed into the direction of the breeze. In a vertical wind turbine, the rotor shaft runs vertically.
Vertical-axis blades lose energy as they turn out of the wind, while horizontal-axis blades work all the time. At many sites, the wind increases higher above the ground, giving an advantage to tall horizontal-axis turbines. The small tower and ground-mounted generators on vertical-axis turbines make them cheaper and easier to maintain.

The first windmills were developed to automate the tasks of grain-grinding and water-pumping and the earliest-known design is the vertical axis system developed in Persia about 500-900 A.D. The first use was apparently water pumping, but the exact method of water transport is not known because no drawings or designs -- only verbal accounts -- are available. The first known documented design is ...

Portions of the following have been adapted from a interview with one of Denmark's pioneering wind turbine designers at, the web site of the Danish wind turbine manufacturer's association, Vindmølleindustrien.
A windmill is a mill that converts the energy of wind into rotational energy by means of vanes called sails or blades. Centuries ago, windmills usually were used to mill grain, pump water, or both. The majority of modern windmills take the form of wind turbines used to generate electricity, or windpumps used to pump water, either for land ...

Modern wind turbines fall into two basic groups: the horizontal-axis variety, as shown in the photo to the far right, and the vertical-axis design, pictured to the immediate right. Horizontal-axis wind turbines typically either have two or three blades. These three-bladed wind turbines are operated "upwind," with the blades facing into the wind.
Wind power is one of the fastest growing sources of energy in the world, rivaled only by solar energy. Using massive turbines designed specifically for ultra-efficiency, wind farms are able to turn a passing breeze into power for our homes, businesses and vehicles.
