Penedo Da Saudade Lighthouse
The Penedo da Saudade Lighthouse ( pt, Farol do Penedo da Saudade ) is located on the Atlantic coast in São Pedro de Moel, District of Leiria, Portugal. The functioning lighthouse was built in 1912 and takes its name from the cliff on which it was constructed. The quadrangular tower is constructed of stone and masonry walls covered by brick tiles, and contains a spiral staircase. It is 32 metres high and the base is at 55 metres above sea level. The location was chosen to be approximately halfway between Berlenga Lighthouse to the south and Cabo Mondego Lighthouse to the north. Originally identified as being necessary during a survey in 1866, the location was not formally agreed until 1902 and construction did not begin until 1909. The Penedo da Saudade lighthouse started operations on February 15, 1912. At that time it was equipped with a rotating 3rd–order optical device with a 500mm focal length and the light was fuelled by oil vapour. From March 1916 to December 1919 th ...

São Pedro De Moel
São Pedro de Moel is a beach community dependent on the city, ''freguesia'' and municipality of Marinha Grande in the District of Leiria, Portugal. According to the 2011 Portuguese Census, it has 389 inhabitants. It is located within the Pinhal de Leiria, south of the mouth of Ribeira de Moel. It is a seaside village, west of the cities of Marinha Grande and Leiria. In 1463 Afonso V gave São Pedro de Moel to the Count of Vila Real. The family had a palace in Leiria and several houses in São Pedro de Moel. They lived on this beach until 1641, when the last Marquis of Vila Real and his son, Duke of Caminha, were executed. The widowed Duquesa de Caminha mourned the death of her husband on a rocky outcrop overlooking the ocean, which is named in his honour - Penedo da Saudade - at the top of which there is a lighthouse of the same name. The legend of the Duquesa de Caminha also claims that the rock still resonates with her lament. Overlooking the beach is the home of the poet ...

Portugal
Portugal, officially the Portuguese Republic ( pt, República Portuguesa, links=yes ), is a country whose mainland is located on the Iberian Peninsula of Southwestern Europe, and whose territory also includes the Atlantic archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, and its Iberian portion is bordered to the west and south by the Atlantic Ocean and to the north and east by Spain, the sole country to have a land border with Portugal. Its two archipelagos form two autonomous regions with their own regional governments. Lisbon is the capital and largest city by population. Portugal is the oldest continuously existing nation state on the Iberian Peninsula and one of the oldest in Europe, its territory having been continuously settled, invaded and fought over since prehistoric times. It was inhabited by pre-Celtic and Celtic peoples who had contact with Phoenicians and Ancient Greek traders, it was ruled by the Ro ...

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The '' catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Characteristic
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for red, ...

Berlenga Lighthouse
Berlenga lighthouse ( pt, Farol da Berlenga), also known as the Duke of Bragança Lighthouse, is a functioning lighthouse situated on the highest point of the granite island of Berlenga Grande (Great Berlenga), which is a nature reserve in the Atlantic Ocean, 10 kilometres west of the town of Peniche in the Leiria District of Portugal. Although planned for construction in the 18th century, work did not start until 1837 and it was completed in 1842. History Following the 1755 earthquake that affected much of Portugal the Marquis of Pombal, who was placed in charge of reconstruction, created an organized Lighthouse Service in 1758 and ordered six lighthouses to be built. The Berlenga lighthouse was intended to be one of these but, unlike the other five, it was not built. Only in December 1836 did the Portuguese Ministry of Finance commission an engineer, Gaudêncio Fontana, to construct a lighthouse on the island. The equipment consisted of a catoptric device, with sixteen oil- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cape Mondego Lighthouse
The Cape Mondego Lighthouse ( pt, Farol do Cabo Mondego) is situated 3 nautical miles NNW of the Mondego River estuary on the Portuguese Atlantic coast, in the parish of Buarcos, in the Figueira da Foz Municipality, in the Coimbra District. It was constructed in 1922, replacing an earlier lighthouse to its south. The lighthouse has a square white masonry tower, above sea level, together with annexes. History The Cape Mondego lighthouse is in the '' Serra da Boa Viagem'' to the north of Buarcos. The first request to the government for the construction of a lighthouse in the Figueira da Foz area was made in 1836. In 1853 a hydrographic survey of the port and sand bar in the Mondego River estuary was carried out to determine the best place for the construction of the lighthouse and in 1854 a study for the construction of a lighthouse was implemented, which identified the most suitable location. A year later, proposals for the construction of the lighthouse were presented but these w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Grid
An electrical grid is an interconnected network for electricity delivery from producers to consumers. Electrical grids vary in size and can cover whole countries or continents. It consists of:Kaplan, S. M. (2009). Smart Grid. Electrical Power Transmission: Background and Policy Issues. The Capital.Net, Government Series. Pp. 1-42. * power stations: often located near energy and away from heavily populated areas * electrical substations to step voltage up or down * electric power transmission to carry power long distances * electric power distribution to individual customers, where voltage is stepped down again to the required service voltage(s). Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same time). This allows transmission of AC power throughout the area, connecting a large number of electricity generators and consumers and poten ...

Lighthouses In Portugal
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
