Lightvessel
A lightvessel, or lightship, is a ship that acts as a lighthouse. They are used in waters that are too deep or otherwise unsuitable for lighthouse construction. Although some records exist of fire beacons being placed on ships in Roman times, the first modern lightvessel was off the Nore sandbank at the mouth of the River Thames in England, placed there by its inventor Robert Hamblin in 1734. The type has become largely obsolete; lighthouses replaced some stations as the construction techniques for lighthouses advanced, while large, automated buoys replaced others. Construction A crucial element of lightvessel design is the mounting of a light on a sufficiently tall mast. Initially, it consisted of oil lamps that could be run up the mast and lowered for servicing. Later vessels carried fixed lamps which were serviced in place. Fresnel lenses were used as they became available, and many vessels housed them in small versions of the lanterns used in lighthouses. Some lightship ...

The Lightship
''The Lightship'' is a 1985 American drama film directed by Jerzy Skolimowski. The film stars Klaus Maria Brandauer and Robert Duvall, with early appearances by Arliss Howard and William Forsythe. The film is based on the novella "Das Feuerschiff" ("The Lightship" in German) by German author Siegfried Lenz which had previously been made into a German film of the same title in 1963. The film was the last made by CBS Theatrical Films, which went out of business in November 1985. The film was distributed by Castle Hill Productions just nine months after the closure of the studio. Plot The story follows the crew of a small ship run by a man named Miller. Sailing out to sea, the ship is taken over by three criminals, one of them named Caspary. Just when they think they are safe, the criminals find themselves battling the crew for control of the vessel. The conflict between the captain (Brandauer) and his son is an important part of the plot. The son wants to subdue the criminals, C ...

Siegfried Lenz
Siegfried Lenz (; 17 March 19267 October 2014) was a German writer of novels, short stories and essays, as well as dramas for radio and the theatre. In 2000 he received the Goethe Prize on the 250th Anniversary of Johann Wolfgang von Goethe's birth. He won the 2010 International Nonino Prize in Italy. Life Siegfried Lenz was born in Lyck, East Prussia (now Ełk, Poland), the son of a customs officer. After graduating in 1943 he was drafted into the '' Kriegsmarine''. According to documents released in June 2007, he joined the Nazi Party at the age of 18 on 20 April 1944 along with several other German authors and personalities such as Dieter Hildebrandt and Martin Walser. However Lenz subsequently said he had been included in a collective ‘joining’ of the Party without his knowledge. In World War II he was a soldier in the German Kriegsmarine and served as a Fähnrich zur See (officer cadet) on the Admiral Scheer, the German auxiliary cruiser Hansa, and for a short per ...

Lightcraft
The Lightcraft is a space- or air-vehicle driven by beam-powered propulsion, the energy source powering the craft being external. It was conceptualized by aerospace engineering professor Leik Myrabo at Rensselaer Polytechnic Institute in 1976, who developed the concept further with working prototypes, funded in the 1980s by the Strategic Defense Initiative organization, and the decade after by the ''Advanced Concept Division'' of the US Air Force AFRL, NASA's MFSC and the Lawrence Livermore National Laboratory. When a Lightcraft is in the atmosphere, air is used as the propellant material (reaction mass). In space, it would need to provide the propellant material from onboard tanks or from an ablative solid. By leaving the vehicle's power source on the ground and by using ambient atmosphere as a reaction mass for much of its ascent, a Lightcraft could potentially be capable of delivering a very large percentage of its launch mass to orbit as an SSTO, a difficult task for ch ...

Light Displacement
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A merc ...

Gerard Love
Teenage Fanclub are a Scottish alternative rock band formed in Bellshill near Glasgow in 1989. The group were founded by Norman Blake (vocals, guitar), Raymond McGinley (vocals, lead guitar) and Gerard Love (vocals, bass), all of whom shared lead vocals and songwriting duties until Love's departure in 2018. As of 2019, the band's lineup consists of Blake, McGinley, Francis Macdonald (drums, vocals), Dave McGowan (bass, vocals) and Euros Childs (keyboards, vocals). In concert, the band usually alternate among its songwriters, giving equal playing time to each one's songs. Although often pegged as alternative rock, the group have incorporated a wide variety of elements from various music styles in their songs. Teenage Fanclub have had a succession of drummers, namely Francis Macdonald, Brendan O'Hare and Paul Quinn. Keyboardist Finlay Macdonald (no relation) has also been a member. As of April 2021, the band have released eleven studio albums and two compilation albums. Histor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Sail
Solar sails (also known as light sails and photon sails) are a method of spacecraft propulsion using radiation pressure exerted by sunlight on large mirrors. A number of spaceflight missions to test solar propulsion and navigation have been proposed since the 1980s. The first spacecraft to make use of the technology was IKAROS, launched in 2010. A useful analogy to solar sailing may be a sailing boat; the light exerting a force on the mirrors is akin to a sail being blown by the wind. High-energy laser beams could be used as an alternative light source to exert much greater force than would be possible using sunlight, a concept known as beam sailing. Solar sail craft offer the possibility of low-cost operations combined with long operating lifetimes. Since they have few moving parts and use no propellant, they can potentially be used numerous times for delivery of payloads. Solar sails use a phenomenon that has a proven, measured effect on astrodynamics. Solar pressure affec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Lightships Of The United States
This is a list of lightships of the United States, listing lightships operated by the United States government. The first US lightship was put in place off of Willoughby Spit in Chesapeake Bay, Virginia, in 1820. Lightships remained in service in the United States until March 29, 1985, when the last ship, the ''Nantucket I'', was decommissioned. During that period, lightships were operated by several branches of the government: by the Lighthouse Establishment from 1820 to 1852, the Lighthouse Board from 1852 to 1910, the Lighthouse Service from 1910 to 1939, and the Coast Guard A coast guard or coastguard is a maritime security organization of a particular country. The term embraces wide range of responsibilities in different countries, from being a heavily armed military force with customs and security duties to ... from 1939 to 1985. The naming conventions used for lightships are not consistent. Until 1867, there was no uniform method to refer to individual lightships. ...
