  2. Attic fan - Wikipedia

    en.wikipedia.org/wiki/Attic_fan

    Wind-powered roof turbine ventilator. Mechanical attic ventilation fans may be powered in a variety of different ways. Most attic ventilators fitted to homes are powered off mains electricity. A trend towards solar-powered attic ventilators is observable in the interest of conserving electricity and lowering monthly utility bills.

  4. Unconventional wind turbines - Wikipedia

    en.wikipedia.org/wiki/Unconventional_wind_turbines

    Counter-rotating wind turbines Light pole wind turbine. Unconventional wind turbines are those that differ significantly from the most common types in use.. As of 2024, the most common type of wind turbine is the three-bladed upwind horizontal-axis wind turbine (HAWT), where the turbine rotor is at the front of the nacelle and facing the wind upstream of its supporting turbine tower.

  5. Wind turbine - Wikipedia

    en.wikipedia.org/wiki/Wind_turbine

    When a turbine is mounted on a rooftop the building generally redirects wind over the roof and this can double the wind speed at the turbine. If the height of a rooftop mounted turbine tower is approximately 50% of the building height it is near the optimum for maximum wind energy and minimum wind turbulence.

  6. Passive ventilation - Wikipedia

    en.wikipedia.org/wiki/Passive_ventilation

    The ventilation system of a regular earthship Dogtrot houses are designed to maximise natural ventilation. A roof turbine ventilator, colloquially known as a 'Whirly Bird' is an application of wind driven ventilation. Passive ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems.

  7. Savonius wind turbine - Wikipedia

    en.wikipedia.org/wiki/Savonius_wind_turbine

    The most ubiquitous application of the Savonius wind turbine is the Flettner ventilator, which is commonly seen on the roofs of vans and buses [where?] and is used as a cooling device. This rotor was developed for ventilation by the German aircraft engineer Anton Flettner in the 1920s. [10] It uses the Savonius wind turbine to drive an ...

  8. Turby wind turbine - Wikipedia

    en.wikipedia.org/wiki/Turby_wind_turbine

    The turbine consists of three vertical symmetrical airfoil blades, each having a helical twist. The helical feature spreads the torque evenly over the entire revolution, thus preventing the destructive pulsations of the straight-bladed giromill (Darrieus turbine). The wind pushes each blade around on both the windward and leeward sides of the ...
