10' x 13' Rectangular Cantilever Patio Umbrella. If you're looking for a non-circular canopy shape, Morse recommends an option like this one. It has a single wind vent and comes in your choice of ...
Parts of an umbrella [2]. The word parasol is a combination of the Latin parare, and sol, meaning 'sun'. [3] Parapluie (French) similarly consists of para combined with pluie, which means 'rain' (which in turn derives from pluvia, the Latin word for rain); the usage of this word was prevalent in the nineteenth century.

An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub
A portable camping toilet has a seat and a small waste tank. Adding a packet of chemicals to the waste tank reduces odors and bacteria, until the waste can be dumped at an appropriate facility. They are used in camping, travel trailers, caravans, and camper vans. They may also be used on small boats which lack a built-in marine toilet.
In the event of skew winds the "wind pressure" on the swept area causes a yawing moment around the tower axis (z-axis) which orients the rotor. [1] The tail fin (or wind vane) is commonly used for small wind turbines since it offers a low cost and reliable solution. It is however unable to cope with the high moments required to yaw the nacelle ...
A nacelle / n ə ˈ s ɛ l / is a cover housing that houses all of the generating components in a wind turbine, including the generator, gearbox, drive train, and brake assembly. [1]
The bladeless design of ion wind generators could make wind power more environmentally friendly, as current "wind power plants represent a risk of bird mortality." [13] Wind turbines have maximum speeds of operation which vary by design. Wind turbines shut down when "cut-out" speeds are exceeded to prevent damage. [14]
