The Ocean Cleanup
The Ocean Cleanup is a nonprofit environmental engineering organization based in the Netherlands, that develops technology to extract plastic pollution from the oceans and intercept it in rivers before it can reach the ocean. After initial testing and prototyping in the North Sea they deployed their first full-scale prototype in the Great Pacific Garbage Patch. It ran into difficulty after two months and was towed to Hawaii for inspection and repair. In June 2019, their second prototype system was deployed. They also deployed their river technology, the Interceptor, in two locations in 2019, revealed the project publicly in October 2019, and deployed another in 2020. In 2021, they announced that the prototype testing of System 002 was successful. In 2022, the first Interceptor Original deployed in the United States was installed at Ballona Creek near Los Angeles, California. The organization conducts scientific research into oceanic plastic pollution. It was founded in 2013 by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delft
Delft () is a city and municipality in the province of South Holland, Netherlands. It is located between Rotterdam, to the southeast, and The Hague, to the northwest. Together with them, it is part of both the Rotterdam–The Hague metropolitan area and the Randstad. Delft is a popular tourist destination in the Netherlands, famous for its historical connections with the reigning House of Orange-Nassau, for its blue pottery, for being home to the painter Jan Vermeer, and for hosting Delft University of Technology (TU Delft). Historically, Delft played a highly influential role in the Dutch Golden Age. In terms of science and technology, thanks to the pioneering contributions of Antonie van Leeuwenhoek and Martinus Beijerinck, Delft can be considered to be the birthplace of microbiology. History Early history The city of Delft came into being beside a canal, the 'Delf', which comes from the word ''delven'', meaning to delve or dig, and this led to the name Delft. At the ...

Ocean Gyre
In oceanography, a gyre () is any large system of circulating ocean currents, particularly those involved with large wind movements. Gyres are caused by the Coriolis effect; planetary vorticity, horizontal friction and vertical friction determine the circulatory patterns from the '' wind stress curl'' (torque). ''Gyre'' can refer to any type of vortex in an atmosphere or a sea, even one that is human-created, but it is most commonly used in terrestrial oceanography to refer to the major ocean systems. Major gyres The following are the five most notable ocean gyres:The five most notable gyres PowerPoint Presentation * Indian Ocean Gyre * [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cast Away
''Cast Away'' is a 2000 American survival drama film directed and produced by Robert Zemeckis and starring Tom Hanks, Helen Hunt, and Nick Searcy.

Sea Anchor
A sea anchor (also known as a parachute anchor, drift anchor, drift sock, para-anchor or boat brake) is a device that is streamed from a boat in heavy weather. Its purpose is to stabilize the vessel and to limit progress through the water. Rather than tethering the boat to the seabed with a conventional anchor, a sea anchor provides hydrodynamic drag, thereby acting as a brake. Normally attached to a vessel's bows, a sea anchor can prevent the vessel from turning broadside to the waves and being overwhelmed by them. Early sea anchors were crude devices, but today most take the form of a marine drogue parachute. These are so efficient that they need a tripping line to collapse the parachute for retrieval. Being made of fabric, a sea parachute may be bagged and easily stowed when not in use. A similar device to the sea anchor is the much smaller drogue, which is streamed from a vessel's stern in strong winds so as to slow the boat to prevent pitchpoling or broaching in a ...

High-density Polyethylene
High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic lumber. HDPE is commonly recycled, and has the number "2" as its resin identification code. In 2007, the global HDPE market reached a volume of more than 30 million tons. Properties HDPE is known for its high strength-to-density ratio. The density of HDPE ranges from 930 to 970 kg/m3. The standard method to test plastic density is ISO 1183 part 2 (gradient columns), alternatively ISO 1183 part 1MVS2PRO density analyzer. Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 M ...

Boom (containment)
A containment boom is a temporary floating barrier used to contain an oil spill. Booms are used to reduce the possibility of polluting shorelines and other resources, and to help make recovery easier. Booms help to concentrate oil in thicker surface layers so that skimmers, vacuums, or other collection methods can be used more effectively. They come in many shapes and sizes, with various levels of effectiveness in different types of water conditions. Often the first containment method to be used and the last equipment to be removed from the site of an oil spill, they are "the most commonly used and most environmentally acceptable response technique to clean up oil spills in the United States." Booms used in oil spills can be seen as they rest on the surface of the water, but can have between 45 and 120 cm (18 to 48 inches) of material that hangs beneath the surface. They are effective in calm water, but as wave height increases oil or other contaminants can easily wash ove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scale Model
A scale model is a physical model which is geometrically similar to an object (known as the prototype). Scale models are generally smaller than large prototypes such as vehicles, buildings, or people; but may be larger than small prototypes such as anatomical structures or subatomic particles. Models built to the same scale as the prototype are called mockups. Scale models are used as tools in engineering design and testing, promotion and sales, filmmaking special effects, military strategy, and hobbies such as rail transport modeling, wargaming and racing; and as toys. Model building is also pursued as a hobby for the sake of artisanship. Scale models are constructed of plastic, wood, or metal. They are usually painted with enamel, lacquer, or acrylics, and decals may be applied for lettering and fine details. They may be built from scratch, or from commercially made kits, either out of the box or modified (known as kitbashing). Model prototypes include all type ...

Award
An award, sometimes called a distinction, is something given to a recipient as a token of recognition of excellence in a certain field. When the token is a medal, ribbon or other item designed for wearing, it is known as a decoration. An award may be described by three aspects: 1) who is given 2) what 3) by whom, all varying according to purpose. The recipient is often to a single person, such as a student or athlete, or a representative of a group of people, be it an organisation, a sports team or a whole country. The award item may be a decoration, that is an insignia suitable for wearing, such as a medal, badge, or rosette (award). It can also be a token object such as certificate, diploma, championship belt, trophy, or plaque. The award may also be or be accompanied by a title of honor, as well as an object of direct value such as prize money or a scholarship. Furthermore, an honorable mention is an award given, typically in education, that does not confer the recipient(s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Design Museum
The Design Museum in Kensington, London exhibits product, industrial, graphic, fashion, and architectural design. In 2018, the museum won the European Museum of the Year Award. The museum operates as a registered charity, and all funds generated by ticket sales aid the museum in curating new exhibitions. History The museum was founded in 1989 by Sir Terence Conran, with Stephen Bayley was inaugural CEO, after the two men had collaboratively created the highly successful exhibition space known as The Boilerhouse at the Victoria and Albert Museum (V&A). Shad Thames site The museum was originally housed in a former 1940s banana warehouse on the south bank of the River Thames in the Shad Thames area in SE1 London. The conversion of this warehouse altered it beyond recognition, to resemble a building in the International Modernist style of the 1930s. This was funded by many companies, designers and benefactors. The museum was principally designed by the Conran group, with ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conveyor Belt
A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types of conveyor systems. A belt conveyor system consists of two or more pulleys (sometimes referred to as drums), with a closed loop of carrying medium—the conveyor belt—that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the unpowered pulley is called the idler pulley. There are two main industrial classes of belt conveyors; Those in general material handling such as those moving boxes along inside a factory and bulk material handling such as those used to transport large volumes of resources and agricultural materials, such as grain, salt, coal, ore, sand, overburden and more. Overview Conveyors are durable and reliable components used in automated distribution and warehousing, as well as manufacturing and p ...

Manta Ray
Manta rays are large rays belonging to the genus '' Mobula'' (formerly its own genus ''Manta''). The larger species, '' M. birostris'', reaches in width, while the smaller, '' M. alfredi'', reaches . Both have triangular pectoral fins, horn-shaped cephalic fins and large, forward-facing mouths. They are classified among the Myliobatiformes ( stingrays and relatives) and are placed in the family Myliobatidae (eagle rays). They have the largest brains and brain to body ratio of all fish, and can pass the mirror test. Mantas are found in warm temperate, subtropical and tropical waters. Both species are pelagic; ''M. birostris'' migrates across open oceans, singly or in groups, while ''M. alfredi'' tends to be resident and coastal. They are filter feeders and eat large quantities of zooplankton, which they gather with their open mouths as they swim. However, research suggests that the majority of their diet (73%) actually comes from mesopelagic sources. Gestation lasts ove ...
