Trompe L’oeil Effect
A trompe is a water-powered air compressor, commonly used before the advent of the electric-powered compressor. A trompe is somewhat like an airlift pump working in reverse. Trompes were used to provide compressed air for bloomery furnaces in Catalonia and the USA. The presence of a trompe is a signature attribute of a Catalan forge, a type of bloomery furnace. Trompes can be enormous. At Canadian Hydro Developers' Ragged Chute facility in New Liskeard, Ontario, water falls down a shaft deep and across to generate compressed air for mining equipment and ventilation.Ragged Chutes Operation Trompes are very simple devices. They consist of four main parts: ''water-supply pipe'' or ''shaft'' with an ''air-inlet'' inside it, ''water outflow pipe'', '' ...[...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Catalan Forge
A bloomery is a type of metallurgical furnace once used widely for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a ''bloom''. The mix of slag and iron in the bloom, termed '' sponge iron'', is usually consolidated and further forged into wrought iron. Blast furnaces, which produce pig iron, have largely superseded bloomeries. Process A bloomery consists of a pit or chimney with heat-resistant walls made of earth, clay, or stone. Near the bottom, one or more pipes (made of clay or metal) enter through the side walls. These pipes, called ''tuyeres'', allow air to enter the furnace, either by natural draught or forced with bellows or a trompe. An opening at the bottom of the bloomery may be used to remove the bloom, or the bloomery can be tipped over and the bloom removed from the top. The first step taken before the bloomery can be used is the preparation of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hydroelectric
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Pumps
A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy. Pumps can be classified into three major groups according to the method they use to move the fluid: ''direct lift'', ''displacement'', and ''gravity'' pumps. Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis. When a casing contains only one revolving impeller, it is called a single-stage pump. When ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Energy Conversion
Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. In physics, energy is a quantity that provides the capacity to perform work or moving, (e.g. Lifting an object) or provides heat. In addition to being converted, according to the law of conservation of energy, energy is transferable to a different location or object, but it cannot be created or destroyed. The energy in many of its forms may be used in natural processes, or to provide some service to society such as heating, refrigeration, lighting or performing mechanical work to operate machines. For example, to heat a home, the furnace burns fuel, whose chemical potential energy is converted into thermal energy, which is then transferred to the home's air to raise its temperature. Limitations in the conversion of thermal energy Conversions to thermal energy from other forms of energy may occur with 100% efficiency. Conversion among non-thermal forms of energy m ...

Hydraulic Compressor
A hydraulic compressor is a type of compressor that is designed to convert hydraulic power to pneumatic power. It is used across various industries to improve the efficiency of certain types of machinery. Hydraulic compressors have a hydraulic pump to push air through a pipe, which forces a motor to spin. The motor powers the internal air compressor, releasing air in a chamber as a result. Compressors became more popularized in 1799 when Englishman George Medhurst invented a motorized air compressor as a means for propulsion. They have technologically advanced to the point where they can achieve greater force and precision than humans. Uses Because of the relatively cheap and easy installment of hydraulic compressors, many industries have implemented them into their equipment to effectively work and provide better results. This includes agriculture, automotive, medical, and industrial companies that require engineers or workers to have more output and innovation. Agricul ...

Mother Earth News
''Mother Earth News'' is a bi-monthly American magazine that has a circulation of 500,520 . It is published in Topeka, Kansas. Since its founding, ''Mother Earth News'' has promoted renewable energy, recycling, family farms, good agricultural practices, better eating habits, medical self-care, more meaningful education and affordable housing. The magazine approaches environmental problems from a down-to-earth, practical, simple living, how-to standpoint. History Founders John and Jane Shuttleworth started the magazine on a "shoestring" budget of $1500, published from home in 1970. The first issue was published in January of that year. (John Shuttleworth died on March 29, 2009, at his home in Evergreen, Colorado, at the age of 71.) The magazine was originally published in Madison, Ohio, and moved to Hendersonville, North Carolina, later. The headquarters is in Topeka, Kansas. It had a scrappy, no-frills style and appearance throughout the 1970s. ''Mother Earth News'' embraced ...

Pulser Pump
A pulser pump is a gas lift device that uses gravity to pump water to a higher elevation. It has no moving parts. Operation A pulser pump makes use of water that flows through pipes and an air chamber from an upper reservoir to a lower reservoir. The intake is a trompe, which uses water flow to pump air to a separation chamber; air trapped in the chamber then drives an airlift pump. The top of the pipe that connects the upper reservoir to the air chamber is positioned just below the water surface. As the water drops down the pipe, air is sucked down with it. The air forms a "bubble" near the roof of the air chamber. A narrow riser pipe extends from the air chamber up to the higher elevation to which the water will be pumped. Initially the water level will be near the roof of the air chamber. As air accumulates, pressure builds, which will push water up into the riser pipe. At some point the "air bubble" will extend below the bottom of the riser pipe, which will allow some of the a ...

Hydraulic Ram
A hydraulic ram, or hydram, is a cyclic water pump powered by hydropower. It takes in water at one "hydraulic head" (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate. The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination higher in elevation than the source. In this situation, the ram is often useful, since it requires no outside source of power other than the kinetic energy of flowing water. History The Alhambra, built by Nasrid Sultan Ibn al-Ahmar of Granada beginning AD1238, used a hydram to raise water. Through a first reservoir, filled by a channel from the Darro River, water emptied via a large vertical channel into a second reservoir bene ...

Sprengel Pump
The Sprengel pump is a vacuum pump that uses drops of mercury falling through a small-bore capillary tube to trap air from the system to be evacuated. It was invented by Hanover-born chemist Hermann Sprengel in 1865 while he was working in London. The pump created the highest vacuum achievable at that time, less than 1 mPa (approximately 1×10−8 atm). Operation The supply of mercury is contained in the reservoir on the left. It flows over into the bulb ''B'', where it forms drops which fall into the long tube on the right. These drops entrap between them the air in ''B''. The mercury which runs out is collected and poured back into reservoir on the left. In this manner practically all the air can be removed from the bulb ''B'', and hence from any vessel ''R'', which may be connected with ''B''. At ''M'' is a manometer which indicates the pressure in the vessel ''R'', which is being exhausted. Falling mercury drops compress the air to atmospheric pressure which is released whe ...
