Meander Dam
The Meander Dam is a concrete gravity dam across the Upper Meander River, located in northern Tasmania, Australia. The impounded reservoir is called Lake Huntsman. The dam was constructed in 2006 by the Tasmanian Rivers & Water Supply Commission for the principal purpose of delivering a reliable supply of irrigation water to the Meander Valley, estimated at . Adjacent to the dam is a small conventional hydroelectric power station. Features and location Proposals to build a dam on the Meander River below Warners Creek date back to at least 1968. The site was cleared in preparation for dam construction during the last 1980s. In 1995 a report by engineering consultants, GHD Group, stated that the lack of a reliable water supply for irrigation in the Meander Catchment is seen as a key factor limiting potential future expansion of agricultural enterprises. The pressure on water resources in the Meander Catchment resulted in the need to limit and sometimes prohibit the extract ...

Tasmanian Parliament
The Parliament of Tasmania is the bicameral legislature of the Australian state of Tasmania. It follows a Westminster-derived parliamentary system and consists of the Governor of Tasmania, the Tasmanian House of Assembly (the lower house), and Tasmanian Legislative Council (the upper house). Since 1841, both Houses have met in Parliament House, Hobart. The Parliament of Tasmania first met in 1856. The powers of the Parliament are prescribed in the Constitution of Tasmania, as amended from time to time. Since the Federation of Australia in 1901, Tasmania has been a state of the Commonwealth of Australia, and the Constitution of Australia regulates its relationship with the Commonwealth. Under the Australian Constitution, Tasmania ceded certain legislative and judicial powers to the Commonwealth, but retained complete independence in all other areas. In practice, however, the independence of the Australian states has been greatly eroded by the increasing financial domination of th ...

Dams In Tasmania
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric Power Stations In Tasmania
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.

Energy Infrastructure Completed In 2008
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydro Tasmania
Hydro Tasmania, known for most of its history as the Hydro-Electric Commission (HEC) or The Hydro, is the trading name of the Hydro-Electric Corporation, a Tasmanian Government business enterprise which is the predominant electricity generator in the state of Tasmania, Australia. The Hydro was originally oriented towards hydro-electricity, due to Tasmania's dramatic topography and relatively high rainfall in the central and western parts of the state. Today Hydro Tasmania operates thirty hydro-electric and one gas power station, and is a joint owner in three wind farms. The Minister for Energy, currently the Hon. Guy Barnett MP, has portfolio responsibility for Hydro Tasmania. Hydro Tasmania operates under the ''Government Business Enterprises (GBE) Act'' 1995 and the ''Hydro-Electric Corporation Act'' 1995, and has a reporting requirement to the Treasurer of Tasmania, currently the Hon. Michael Ferguson (Australian politician) MP. Hydro Tasmania was projected to pay the Tasma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electricity
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...

Water Turbine
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation. Water turbines are mostly found in dams to generate electric power from water potential energy. History Water wheels have been used for hundreds of years for industrial power. Their main shortcoming is size, which limits the flow rate and head that can be harnessed. The migration from water wheels to modern turbines took about one hundred years. Development occurred during the Industrial revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time. Swirl The word turbine was introduced by the French engineer Claude Burdin in the early 19th century and is derived from the Greek word "τύρβη" ...

Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine for d ...

Stateline (TV Program)
''Stateline'' was a television current affairs program produced by the Australian Broadcasting Corporation. It provided analysis of state and municipal politics as well as insight into state and regional issues in a current affairs journalistic style. The program was known for its interviews with politicians, and for its coverage of important regional issues. The ABC announced in December 2010 that the state-based current affairs program ''Stateline'' would be folded into a new '' 7.30'' brand from March 2011. The change saw ''7.30'' extended to five nights a week, although Friday editions continue to be presented locally and focus on state affairs. Format It was broadcast on ABC1 on Fridays at 7:30 pm (in place of '' The 7.30 Report''), with eight separate state and territory specific editions. It was also broadcast on the new digital channel ABC2 after its launch in March 2005. With the launch of ABC News 24 ABC News (formerly ABC News 24; also referred to as the AB ...
