An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined to extract the valuable element, or elements.
Tidal power or tidal energy is a form of hydropower that converts the energy obtained from tides into useful forms of power, mainly electricity.
Joseph William Stefano was an American screenwriter, best known for adapting Robert Bloch's novel as the script for Alfred Hitchcock's film Psycho, and for being the producer and co-writer of the original The Outer Limits TV series.
Asteroid mining is the exploitation of raw materials from asteroids and other minor planets, including near-Earth objects.
Many parts of the outer Solar System have been considered for possible future colonization. Most of the larger moons of the outer planets contain water ice, liquid water, and organic compounds that might be useful for sustaining human life.
The Severn Estuary is the estuary of the River Severn, the longest river in Great Britain. It is the confluence of four major rivers, being the Severn, Wye, Usk and Avon, and other smaller rivers. Its high tidal range, approximately 50 feet (15 m), means that it has been at the centre of discussions in the UK regarding renewable energy.
The Severn Barrage refers to a range of ideas for building a barrage from the English coast to the Welsh coast over the Severn tidal estuary. Ideas for damming or barraging the Severn estuary have existed since the 19th century. The building of such a barrage would constitute an engineering project comparable with some of the world's biggest. The purposes of such a project has typically been one, or several of: transport links, flood protection, harbour creation, or tidal power generation. In recent decades it is the latter that has grown to be the primary focus for barrage ideas, and the others are now seen as useful side-effects. Following the Severn Tidal Power Feasibility Study (2008–10), the British government concluded that there was no strategic case for building a barrage but to continue to investigate emerging technologies.
In June 2013 the Energy and Climate Change Select Committee published its findings after an eight-month study of the arguments for and against the Barrage. MPs said the case for the barrage was unproven. They were not convinced the economic case was strong enough and said the developer, Hafren Power, had failed to answer serious environmental and economic concerns.
The engineering design process is a methodical series of steps that engineers use in creating functional products and processes. The process is highly iterative - parts of the process often need to be repeated many times before another can be entered - though the part(s) that get iterated and the number of such cycles in any given project may vary.
…It is a decision making process in which the basic sciences, mathematics, and engineering sciences are applied to convert resources optimally to meet a stated objective. Among the fundamental elements of the design process are the establishment of objectives and criteria, synthesis, analysis, construction, testing and evaluation.
The mineral industry of Botswana has dominated the national economy since the 1970s. Diamond has been the leading component of the mineral sector since large-scale diamond production began in 1972. Most of Botswana's diamond production is of gem quality, resulting in the country's position as the world's leading producer of diamond by value. Copper, gold, nickel, and soda ash production also has held significant, though smaller, roles in the economy. In 2005, mining accounted for about 38% of Botswana's real gross domestic product (GDP), and more than 50% of government revenues were derived from mining and mineral-processing activity. In 2005, the nominal value of minerals produced in Botswana exceeded that of 2004 by about 20% in U.S. dollars. Much of the increase was attributed to higher international mineral prices. Diamond, copper-nickel matte, and gold, in order of value, accounted for most of the increase.
Severn Tidal Power Feasibility Study is the name of a UK Government feasibility study into a tidal power project looking at the possibility of using the huge tidal range in the Severn Estuary and Bristol Channel to generate electricity.
The Kalpasar Project envisages building a 30 km dam across the Gulf of Khambat in India for establishing a huge fresh water coastal reservoir for irrigation, drinking and industrial purposes. A 10 lane road link will also be set up over the dam, greatly reducing the distance between Saurashtra and South Gujarat.
The Outer Limits is an American television series that was broadcast on ABC from 1963 to 1965 at 7:30 PM Eastern Time on Mondays. The series is often compared to The Twilight Zone, but with a greater emphasis on science fiction stories. The Outer Limits is an anthology of self-contained episodes, sometimes with a plot twist at the end.
The Outer Limits is a Canadian-American television series that originally aired on Showtime, Syfy and in syndication between 1995 and 2002. The series is a revival of the original The Outer Limits series that aired from 1963–65.
The Outer Trial Bank is a circular artificial island in the Wash, East Anglia, England. It is one of two islands constructed during the 1970s for a governmental water resources scheme.
Renewable energy in Pakistan is a relatively underdeveloped sector; however, in recent years, there has been some interest by environmentalist groups and from the authorities to explore renewable energy resources for energy production in light of the energy crises and power shortages affecting the country. Most of Pakistan's renewable energy comes from hydroelectricity.
