Block Island North Light
Block Island North Light (Lighthouse), built in 1867, is a historic lighthouse on Block Island, Rhode Island ( New Shoreham). History The first light on the site was built in 1829. The current structure at Sandy Point is the fourth lighthouse built on the site and was made of granite and iron in 1867. The light was deactivated in 1973 and United States Fish and Wildlife Service acquired the lighthouse. The lighthouse was listed on the National Register of Historic Places in 1974. After years of neglect, the lighthouse, along with two acres of land, was sold to New Shoreham in 1984 for $1 USD. Following much renovation by the North Light Commission, it was relighted in 1989, and a museum opened on the first floor in 1993. Then, in 2008 the light underwent restoration at Georgetown Ironworks in Massachusetts and was returned in 2009. Finally, on 23 October 2010, a relighting ceremony took place. Structure The building is made of brown granite. The tower is octagonal in shape, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Octagonal
In geometry, an octagon (from the Greek ὀκτάγωνον ''oktágōnon'', "eight angles") is an eight-sided polygon or 8-gon. A '' regular octagon'' has Schläfli symbol and can also be constructed as a quasiregular truncated square, t, which alternates two types of edges. A truncated octagon, t is a hexadecagon, . A 3D analog of the octagon can be the rhombicuboctahedron with the triangular faces on it like the replaced edges, if one considers the octagon to be a truncated square. Properties of the general octagon The sum of all the internal angles of any octagon is 1080°. As with all polygons, the external angles total 360°. If squares are constructed all internally or all externally on the sides of an octagon, then the midpoints of the segments connecting the centers of opposite squares form a quadrilateral that is both equidiagonal and orthodiagonal (that is, whose diagonals are equal in length and at right angles to each other).Dao Thanh Oai (2015), "Equilatera ...

Lighthouses On The National Register Of Historic Places In Rhode Island
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 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Museums In Washington County, Rhode Island
A museum ( ; plural museums or, rarely, musea) is a building or institution that cares for and displays a collection of artifacts and other objects of artistic, cultural, historical, or scientific importance. Many public museums make these items available for public viewing through exhibits that may be permanent or temporary. The largest museums are located in major cities throughout the world, while thousands of local museums exist in smaller cities, towns, and rural areas. Museums have varying aims, ranging from the conservation and documentation of their collection, serving researchers and specialists, to catering to the general public. The goal of serving researchers is not only scientific, but intended to serve the general public. There are many types of museums, including art museums, natural history museums, science museums, war museums, and children's museums. According to the International Council of Museums (ICOM), there are more than 55,000 museums in 202 count ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Block Island Southeast Light
Block Island Southeast Light is a lighthouse located on Mohegan Bluffs at the southeastern corner of Block Island, Rhode Island. It was designated a U.S. National Historic Landmark in 1997 as one of the most architecturally sophisticated lighthouses built in the United States in the 19th century. Description and history Although Congress appropriated $9,000 to build this light in 1856, the funds were used to build a new Block Island North Light after the old one was washed away in a storm. This light was finally built in 1874, with the lamp first lit on February 1, 1875. It is a sophisticated expression of the Gothic Revival executed in brick, and was a marked contrast to earlier lighthouses, which were generally more functional in appearance. The main tower is in height, with an octagonal granite foundation and brick exterior, which rises to a cast iron parapet and open gallery around the lantern chamber. This is topped by a sixteen-sided pyramidal copper roof with a ball venti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Panels
A solar cell panel, solar electric panel, photo-voltaic (PV) module, PV panel or solar panel is an assembly of photovoltaic solar cells mounted in a (usually rectangular) frame, and a neatly organised collection of PV panels is called a photovoltaic system or solar array. Solar panels capture sunlight as a source of radiant energy, which is converted into electric energy in the form of direct current (DC) electricity. Arrays of a photovoltaic system can be used to generate solar electricity that supplies electrical equipment directly, or feeds power back into an alternate current (AC) grid via an inverter system. History In 1839, the ability of some materials to create an electrical charge from light exposure was first observed by the French physicist Edmond Becquerel. Though these initial solar panels were too inefficient for even simple electric devices, they were used as an instrument to measure light. The observation by Becquerel was not replicated again until 1873 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Generator
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. Hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year. Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and the most favorable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas energy sources. Smaller wind turbines are used for applications such as battery charging for auxiliary power for boats or caravans, and to power traffic warning signs. Larger turbines can contribute to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Wind turbines are manufactured in a wide range of ...

Foghorn
A foghorn or fog signal is a device that uses sound to warn vehicles of navigational hazards such as rocky coastlines, or boats of the presence of other vessels, in foggy conditions. The term is most often used in relation to marine transport. When visual navigation aids such as lighthouses are obscured, foghorns provide an audible warning of rock outcrops, shoals, headlands, or other dangers to shipping. Description All foghorns use a vibrating column of air to create an audible tone, but the method of setting up this vibration differs. Some horns, such as the Daboll trumpet, used vibrating plates or metal reeds, a similar principle to a modern electric car horn. Others used air forced through holes in a rotating cylinder or disk, in the same manner as a siren. Semi-automatic operation of foghorns was achieved by using a clockwork mechanism (or "coder") to sequentially open the valves admitting air to the horns; each horn was given its own timing characteristics to help marine ...
