Asian Super Grid
The Asian Super Grid is a project to establish an electrical power transmission network, or super grid, connecting China, South Korea, Taiwan, Mongolia, Russia, and Japan. It will transmit electrical power from renewable sources from areas of the world that are best able to produce it to consumers in other parts of the world. The idea is dependent on development of an ultra-high voltage grid operating at more than 1,000 kilovolts AC and 800 kilovolts DC over thousands of kilometers. It envisions interconnecting grids across regions, nations, and even continents with a capacity of over 10 gigawatts. The concept is the result of an idea by Masayoshi Son, founder and head of the telecom and Internet giant SoftBank Group. After the devastation at the Fukushima Daiichi nuclear plant following the 2011 Tohoku earthquake, Son was so shocked by events that he established the Renewable Energy Institute soon afterwards to help develop and promote renewable energy.

Masayoshi Son
Masayoshi Son ( ja, 孫 正義, translit=Son Masayoshi, ko, 손정의, translit=Son Jeong-ui) (born 11 August 1957) is a Korean-Japanese billionaire technology entrepreneur, investor, financier and philanthropist. A 3rd generation "Zainichi Korean", he naturalized as a Japanese citizen in 1990. He is the founder, chairman and chief executive officer (CEO) of the Japanese holding company SoftBank, CEO of SoftBank Mobile and chairman of UK-based Arm Holdings. Since Son founded SoftBank in 1981, he has made many investments, but the vast majority of those deals failed, and his reputation as an investor rests almost solely on his $20 million investment in Alibaba Group in 2000, a stake that was worth $130 billion in 2018. The morphing of his own telecom company SoftBank Corp. into an investment management firm called SoftBank Group Corp. made him noted worldwide as a stock investor. However, after a number of high-profile setbacks, Son's investing strategy in the first and second S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Renewable Energy
Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy often provides energy for electricity generation to a grid, air and water heating/cooling, and stand-alone power systems. Renewable energy technology projects are typically large-scale, but they are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. Renewable energy is often deployed together with further electrification, which has several benefits: electricity can move heat or objects efficiently, and is clean at the point of consumption. In addition, electrification with renewable energy is more efficient and therefore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HVDC Transmission Lines
A high-voltage direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. Most HVDC links use voltages between 100 kV and 800 kV. However, a 1,100 kV link in China was completed in 2019 over a distance of with a power capacity of 12 GW. With this dimension, intercontinental connections become possible which could help to deal with the fluctuations of wind power and photovoltaics. HVDC allows power transmission between AC transmission systems that are not synchronized. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power. HVDC also allows the transfer of power between grid systems running at different frequencies, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Power In Asia
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 positiv ...

List Of HVDC Projects
This is a list of notable high-voltage direct-current power transmission projects. HVDC projects for long-distance transmission have two (or rarely, more) converter stations and a transmission line interconnecting them. Generally overhead lines are used for interconnection, but an important class of HVDC projects use submarine power cables. A back-to-back station has no transmission line and connects two AC grids at different frequencies or phase counts. Historical HVDC systems used the Thury system of motor-generators but these have all been made obsolete by later developments such as mercury-arc valves (now also obsolete), thyristors, and IGBT power transistors. Legend Line type: * Thury = Series-connected generators as designed by René Thury * Merc = Mercury-arc valve rectifier and inverter * Thyr = Thyristor rectifier and inverter * IGBT = Insulated Gate Bipolar Transistors Line status: Africa Australia and Oceania Asia Europe 2 As of 9 December 2015, Li ...

Fukushima Daiichi Nuclear Disaster
The was a nuclear accident in 2011 at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan. The proximate cause of the disaster was the 2011 Tōhoku earthquake and tsunami, which occurred on the afternoon of 11 March 2011 and remains the most powerful earthquake ever recorded in Japan. The earthquake triggered a powerful tsunami, with 13–14-meter-high waves damaging the nuclear power plant's emergency diesel generators, leading to a loss of electric power. The result was the most severe nuclear accident since the Chernobyl disaster in 1986, classified as level seven on the International Nuclear Event Scale (INES) after initially being classified as level five, and thus joining Chernobyl as the only other accident to receive such classification. While the 1957 explosion at the Mayak facility was the second worst by radioactivity released, the INES ranks incidents by impact on population, so Chernobyl (335,000 people evacuated) and Fukushima (154,000 evacuate ...

Kilovolt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, s, and A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \text\Omega = \frac = \ ...
