Abstract:
A system and method for collecting renewable energy includes a solar panel and a down-sun wind turbine that are mounted on a same crossbeam. In this combination, as the crossbeam is rotated on a support pole, the solar panel is simultaneously rotated through a directional arc θ and an inclination arc Φ in accordance with a predetermined daily schedule that is based on the time of day and the latitude of the system. Also, as the solar panel is moved, the wind turbine is free to follow wind direction and maximize its collection of wind energy. To further maximize the energy collection capability of the system, the wind turbine is located on the crossbeam to remain down-sun from the solar panel and to remain free from wind flow interference that may be caused by the solar panel.

Abstract:
An outdoor light [10] to harness solar and wind energy is described. The street light [10], comprises a pole [12], and a light source [14] fitted at the top part of the pole [12], characterized in that, a reflecting cover [16] shrouds the light source [14] and top part of the pole [12], said reflecting cover [16] is provided with solar panel [18] on top. A vertical axis wind turbine [20] is adapted between the reflecting cover [16] and solar panel [18]. The wind turbine [20] comprises of a power augmentation guide vane [21] having guide vanes [22], an upper wall duct [24] and lower wall duct [26] inclined at an angle of 10 degrees to 80 degrees from the centre axis, said upper wall duct [24] is flared upwards and lower wall duct [26] is flared downwards.
Abstract:
The present invention relates to a self electricity-generating roadside lamp that generates electricity using pressure difference, characterized in that multiple wind power generators are provided inside of the upright post of the roadside lamp. Provided at the upper portion of the upright post is a cambered wind cap; a battery and an electrically connected circuit are provided inside of the upright post; the upright post is of a transparent material and is provided with a salt layer in the north-facing portion. Operation method: an air current passes the cambered air cap and the flow speed increases as the pressure decreases; the air current having a high pressure flows upward and forms a strong ascending air current; on the other hand, a black salt layer inside of the upright post absorbs the heat from sunlight, and the air that has been heated moves upward and forms another strong ascending air current; the two strong ascending air currents push the wind power generators inside of the upright post to rotate and generate power for roadside lamps for illumination. The benefits are: all of the electricity generating equipment is inside of the upright post of the roadside lamp, and therefore has a lower rate of maintenance and lower operation cost. In the present invention, a black salt layer is used as the equipment for solar electricity generation, and is therefore lower in cost and longer in service life compared to solar panels.
