Artificial Sun

Korean Fusion Reactor 'Artificial Sun' sets record for sustaining plasma at 100 million Degree Celsius.

  • KSTAR – South Korean scientists have set a new world record using the Korea Superconducting Tokamak Advanced Research (KSTAR) device, an artificial Sun nuclear fusion reactor.
  • 48 Seconds – The team generated plasma temperatures of 100 million degrees Celsius for 48 seconds (30 seconds in 2021) during tests between December 2023 and February 2024.
  • This temperature is seven times that of the Sun's core, which is 15 million degrees Celsius.
  • Aim – KSTAR aims to sustain plasma temperatures of 100 million degrees Celsius for 300 seconds by 2026.
  • Tokamak – Common way of achieving fusion energy involves a doughnut-shaped reactor called a tokamak in which hydrogen variants are heated to extraordinarily high temperatures to create plasma.
  • The activities of KSTAR will feed into the development of the International Thermonuclear Experimental Reactor (ITER) in Southern France.
  • ITER – ITER is the world’s biggest tokamak which aims to prove the feasibility of fusion.
  • It will not produce any electricity; instead, ITER will resolve the critical scientific and technical issues to take fusion to the point where industrial applications can be envisioned.
  • Funds – ITER is funded and run by seven member parties, China, the European Union, India, Japan, Russia, South Korea and the United States.
  • India – India became a full partner of the ITER Project in 2005.
  • ITER is intended to advance India's own nuclear fusion programmes and research.
  • The Institute for Plasma Research (IPR), a dedicated research institute under the Department of Atomic Energy, supervises the ITER-India as well as India’s two tokamaks, ADITYA-U and SST-1.

China’s artificial Sun, the Experimental Advanced Superconducting Tokamak (EAST) reactor is an advanced nuclear fusion experimental research device.

Quick Facts

Nuclear Fusion

  • Nuclear fusion is defined as the combining of many small nuclei into a large nucleus with the subsequent release of huge amounts of energy.
  • It powers our sun and harnessing this fusion energy could provide an unlimited amount of renewable energy.
  • Nuclear fusion energy is a good choice as the base load energy in the future as it has many advantages.
  • Advantages – Inexhaustibility of resources, inherent safety, no long-lived radioactive wastes, and almost no CO2 emissions.
  • In the experiment, lasers were used to heat a small fuel pellets, having deuterium and tritium, in the inertial confinement fusion process.
  • This pressurised the fuel pellets at conditions similar to that at the centre of the Sun.
  • This triggered the fusion reactions.
  • These reactions released alpha particles (positively charged), which in turn heated the surrounding plasma.
  • [At high temperatures, electrons are ripped from atom’s nuclei and become plasma or the 4th state of matter or an ionised state of matter.]

  • Heated plasma released alpha particles and a self-sustaining reaction called ignition took place.
  • Ignition amplifies the energy output.
  • Significance – This could help provide clean energy for the future.
  • Reproducing the conditions at the centre of the Sun will help studying the states of matter we were unable to create in the lab before.
  • Often referred to as the holy grail of climate solutions, fusion has the potential to provide limitless energy without planet-warming carbon pollution.
  • Nuclear fusion is also called as thermonuclear reaction which is possible only at an extremely high temperature and high pressure to push the hydrogen nuclei closer to fuse with each other.
  • Base load energy refers to the minimum amount of electric power needed to be supplied to the electrical grid at any given time.

One Vehicle, One FASTag

The National Highways Authority of India (NHAI) has rolled out the ‘One Vehicle, One FASTag’ scheme.


  • FASTag is an electronic toll collection system in India, operated by the National Highways Authority of India (NHAI).
  • The fast tag (FASTag) are a Radio Frequency Identification Card (RFID) pasted to the windscreen of the vehicle.
  • These tags store data such as vehicle registration, class of vehicle, engine and chassis number, etc., these details will help to arrive at the exact toll to be charged.
  • The system operates on the lines of a prepaid phone card, which enables electronic payment at tolls on national highways.
  • An RFID reader which is installed few meters from the toll plaza will act a sensor and verify tags validity and the account balance.
  • If the amount is available with the prepaid card, the vehicle may pass through.
  • Where there is a discrepancy in the card the vehicle will be alerted to eject from the lane, and pass through the eject lane.
  • The vehicle can pass any number of toll plazas, all over the country, as long as there is amount in the account, and it can be recharged once the amount gets depleted.
  • Aim – The 'One Vehicle, One FASTag' concept aims to deter the practice of using a single FASTag for multiple vehicles or associating multiple FASTags with one vehicle.
  • Issues – NHAI has taken this initiative after the recent reports of multiple FASTags being issued for a particular vehicle and FASTags being issued without KYC in violation of RBI’s mandate.
  • FASTags are deliberately not fixed on the windscreen of the vehicle, resulting in unnecessary delays at the toll plazas and causing inconvenience to fellow National Highway users.

Users will be free to recharge their FASTag from any bank and different payment methods such as Bharat Bill Payment System (BBPS) UPI internet banking etc.

    3. Securing 8% of votes polled in a general election.
  • Symbols Order – Symbols are allotted to political parties and contesting candidates as per the provisions of the Symbols Order by ECI.
  • Recognised Party – A recognised political party has a reserved symbol that is not allotted to any other candidate in any constituency.
  • RUPPs – RUPPs are either newly-registered parties or those which:
    1. Have not secured enough percentage of votes in the Assembly or general election to become a State party
    2. Those that have never contested elections after being registered.
  • Free Symbols – For RUPPs, one of the free symbols is allotted as a common symbol during an election if that party contests in two Lok Sabha constituencies or in 5% of seats to the Assembly of a State as the case may be.
  • Rule 10B – Rule 10B of the Symbols Order provides that the concession of a common free symbol shall be available to a ‘registered unrecognised party’ for two general elections.
  • Common Symbol – A party shall be eligible for a common symbol in any subsequent general election if it had secured at least 1% of votes polled in the State on the previous occasion when the party availed of this facility.
  • Common symbols are provided to RUPPs based upon an undertaking that they would put up at least 5% of total candidates with regard to said Legislative Assembly election of a State.
  • Such an unrecognised party should however apply for a symbol every time in the prescribed format.
  • This application can be made any time during the period commencing six months prior to the expiry of the term of the Lok Sabha or State Assembly as the case may be.
  • First-Come-First-Served – The symbols are thereafter allotted on a ‘first-come-first-served’ basis.

The candidates set up by recognised parties enjoy the advantage of being listed at the top of the ballot in the Electronic Voting Machine.

New Rules for RUPPs

  • The Election Commission of India, brought in new rules for allocation of symbols to RUPPs, in January 2024.
  • The ECI made it mandatory for the RUPPs to furnish audited accounts of last three financial years, expenditure statements of last two elections, and the signature of the authorized office-bearer of the party along with the application form for symbols.

The EC had in 2014 given directions that RUPPs wanting to avail the benefits of having a common symbol have to submit the proof of having filed up-to-date contribution reports, audited annual accounts, update of election expenditure statements, and their latest organisation details.

Ring of Fire

Taiwan is prone to earthquakes as it lies along the Pacific Ring of Fire, where 90% of the world’s earthquakes take place

  • Circum-Pacific Belt – The Ring of Fire is also referred to as the Circum-Pacific Belt.
  • It is a path along the Pacific Ocean characterized by a string of hundreds of active volcanoes and frequent earthquakes.
  • It is a semicircle or horse shoe in shape and stretches nearly 40,250 kilometres.
  • The majority of Earth’s volcanoes and earthquakes take place along the Ring of Fire.
  • It traces boundaries between several tectonic plates, including the Pacific, Juan de Fuca, Cocos, Indian-Australian, Nazca, North American, and Philippine Plates.
  • Reasons for predominant volcanoes – Along much of the Ring of Fire, plates overlap at convergent boundaries called subduction zones.
  • That is, the plate that is underneath is pushed down, or subducted, by the plate above.
  • As rock is subducted, it melts and becomes magma.
  • The abundance of magma so near to Earth’s surface gives rise to conditions ripe for volcanic activity.

Taiwan's geographical location on the western edge of the Pacific Ring of Fire makes it highly susceptible to seismic activities.

  • A significant exception is the border between the Pacific and North American Plates.
  • This stretch of the Ring of Fire is a transform boundary, where plates move sideways past one another.
  • This type of boundary generates a large number of earthquakes as tension in Earth’s crust builds up and is released.

The Pacific Ring of Fire runs through countries including the USA, Indonesia, Mexico, Japan, Canada, Guatemala, Russia, Bolivia, Ecuador, Chile, Peru, Costa Rica, Philippines, New Zealand, Australia, and Papua New Guinea.
