    What is Dark Energy?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Dark Energy, Dark Energy

    Mains level: Theory of expansion of the universe

    Last week, an international team of researchers has made the first direct detection of dark energy.

    About the Project

    • The XENON1T experiment is the world’s most sensitive dark matter experiment and was operated deep underground at the INFN Laboratori Nazionali del Gran Sasso in Italy.
    • The finding also suggests that experiments like XENON1T, which are designed to detect dark matter, could also be used to detect dark energy.

    What is Dark Energy?

    • Dark energy is an unknown form of energy that affects the universe on the largest scales.
    • The first observational evidence for its existence came from measurements of supernovae, which showed that the universe does not expand at a constant rate; rather, the expansion of the universe is accelerating.
    • Prior to these observations, it was thought that all forms of matter and energy in the universe would only cause the expansion to slow down over time.
    • Measurements of the cosmic microwave background suggest the universe began in a hot Big Bang, from which general relativity explains its evolution and the subsequent large-scale motion.
    • Without introducing a new form of energy, there was no way to explain how an accelerating universe could be measured.

    Does it exist?

    • Since the 1990s, dark energy has been the most accepted premise to account for the accelerated expansion.
    • As of 2021, there are active areas of cosmology research aimed at understanding the fundamental nature of dark energy.

    Dark energy Vs Dark matter

    • Everything we see – the planets, moons, massive galaxies, you, me, this website – makes up less than 5% of the universe.
    • About 27% is dark matter and 68% is dark energy.
    • While dark matter attracts and holds galaxies together, dark energy repels and causes the expansion of our universe.

    IIT-B develops One-time Programmable Memory

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: One-time Programmable Memory

    Mains level: NA

    IIT Bombay researchers have developed a “memory technology” that can, in principle, revolutionise Indian industry and the many applications that need semiconductor chips, such as in the defence sector, automobiles and future aspirations in cell phone manufacturing.

    One-time Programmable Memory

    • Hard disks, flash memory, etc, are examples of memory technology.
    • There is also another form of memory called the one-time programmable memory (OTP) where the memory is written once, stored for a lifetime, and retrieved and used many times.
    • This finds varied uses, one of which is in correcting faulty chips that have been mass produced for specific applications.

    Its utility

    • For instance, think of a chip that helps read off the temperature.
    • Due to a manufacturing defect, the chip may read 100 degree Celsius as 101 degree Celsius.
    • This “offset” of 1 degree may be corrected by storing the error correction parameter in the OTP memory.
    • This is done uniquely for each chip and once stored, the memory corrects the chip’s output for its lifetime.
    • OTP memories are also used for other purposes, mainly three: chip identity, secure information storage and chip calibration for error correction.

    How does it work?

    • To store the correction value, the researchers used eight memory cells, each of which would store one “bit” (that is a value of zero or one).
    • Each of the memory cells consist of an ultrathin silicon dioxide layer which is 10-15 atomic layers thick.
    • This is deposited uniformly over a dinner plate–sized eight-inch silicon wafer to form millions of nanoscale capacitors.
    • The pristine silicon dioxide layer is insulating, passing a very low current [which in digital electronics is read as a “0”].
    • A nanoscale lightning is generated of 3.3 volts to blow the capacitor, leading to a short circuit that produced high current [this is a “1”].
    • Thus, the OTP memory remembers either the “0” state or “1” state through its lifetime.

    Benefits offered

    • The group has successfully demonstrated CMOS 180-nanometre–based, production-ready, eight-bit memory technology.
    • These include successful operation between minus 40 degrees C to 125 degrees C and reliability to ensure excess of 95% yield on eight-bit memories.

    Significance

    • A large fraction of manufactured chips may need to be discarded for faults that can be corrected using this technology.
    • This technology is the first indigenous semiconductor memory technology adoption to manufacturing at 180-nanometre node.
    • Thus, this is a major national milestone for semiconductor innovation.

    In news: Battle of Chamkaur (1704)

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Battle of Chamkaur

    Mains level: NA

    The new Punjab CM represents the Assembly constituency of Chamkaur Sahib, which is of significance in Sikh history.

    For such history-related topics, one must not forget to note the contemporaries of a particular period.

    The Battle of Chamkaur

    • The coalition forces of Mughals and hill rajas led by Wazir Khan, the Nawab of Sirhind, had laid siege to Anandpur Sahib in the hope of capturing Guru Gobind Singh in May 1704.
    • After seven months of fighting and heavy losses, the coalition forces offered a safe passage to the Guru and his followers.
    • The heads of the coalition pledged they would not harm the Guru, his family, or his soldiers.
    • The peace treaty was sent in the name of Emperor Aurangzeb himself.
    • But when Gobind Singh and his followers stepped out of the Anandpur Sahib fort on the night of December 20, they were attacked.
    • Historically, this was where that Guru Gobind Singh lost two of his elder sons in a battle with the coalition forces of Mughals and the hill rajas.

    What happened at Chamkaur Sahib?

    • The Guru, accompanied by panj piaras (the five Sikhs he had initially baptised), his elder sons and around 40 soldiers, regrouped in a fortress-like two-storey house, with high compound walls made of mud.
    • They were surrounded by an army commandeered by Wazir Khan and Sher Mohammed Khan, the younger brother of Malerkotla’s chieftain.
    • The Guru sent out soldiers in small squads for hand-to-hand combat. Two such attacks were led by his sons, both of whom died fighting.
    • Three of the panj piaras — Mohkam Singh, Himmat Singh and Sahib Singh — too died fighting.

    How did the battle conclude?

    • When very few soldiers were left, they decided the Guru should leave so that he could carry on his mission.
    • It was at the Chamkaur fort that panj piaras issued an edict (hukumnama) ordering the Guru to leave.
    • This was the first edict issued by panj piaras after the formation of the Khalsa on April 13, 1699.
    • Before leaving, the Guru gave his attire and distinguishing kalgi to Sangat Singh, a Mazhabi Sikh who resembled him.
    • Three other soldiers too left the fort, and went in separate directions. The following day, the enemy forced their way inside to find only two soldiers who fought till their last breath.
    • Five days later, Guru Gobind Singh’s two younger sons, aged nine and seven, were bricked alive for refusing to convert.

    Arctic ice is disappearing: How clouds interact with sea ice change

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Polynya

    Mains level: Glaciers retreat at the Poles

    Temperatures in the Arctic, for example, have been rising much faster than the rest of the planet. Experts, for the longest time, have attributed the crisis to how clouds interact with sea ice, essentially frozen seawater.

    Role of Polynya

    • Decades of research have pointed that the losses in Arctic Sea ice cover allow for the formation of more clouds near the ocean’s surface.
    • New research by NASA has now shown that more heat and moisture is released through a large hole in sea ice called a polynya, which fuels the formation of more clouds.
    • This traps heat in the atmosphere and hinders the refreezing of new sea ice.

    What is Polynya?

    • A polynya is an area of open water surrounded by sea ice.
    • It is now used as a geographical term for an area of unfrozen seawater within otherwise contiguous pack ice or fast ice.
    • It refers to a natural ice hole and was adopted in the 19th century by polar explorers to describe navigable portions of the sea.
    • There are two main types of polynyas:
    1. Coastal polynyas, which can be found year-round near the Antarctic and Arctic coasts and are mainly created by strong winds pushing the ice away from the coast, and
    2. Mid-sea or open-ocean polynyas, which may be found more sporadically in the middle of an ice pack in certain locations, especially around Antarctica.

    What is the new research about?

    • The research stated that low clouds over the polynya emitted more energy or heat than clouds in adjacent areas covered by sea ice.
    • The polynya did refreeze, but only after the increased cloud cover and heat under the clouds persisted for about a week.
    • The extra clouds and increased cloud radiative effect to the surface remained for some time after the polynya froze.
    • The sea ice acts like a cap or a barrier between the relatively warm ocean surface and the cold and dry atmosphere above, so more heat and moisture from the ocean into the atmosphere.
    • This warming slows down the growth of the sea ice.

  • Trade Sector Updates – Falling Exports, TIES, MEIS, Foreign Trade Policy, etc.

    Service Exports from India Scheme (SEIS)

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Service Exports from India Scheme (SEIS)

    Mains level: Export promotion schemes in India

    The Directorate General of Foreign Trade has imposed a cap on the total entitlement under the Services Exports from India Scheme (SEIS) at Rs 5 crore per exporter for shipments done in 2019-20 (FY20). The move is expected to benefit small businesses in the services sector.

    About SEIS

    • Service Exports from India Scheme (SEIS) aims to promote export of services from India by providing duty scrip credit for eligible exports.
    • Under the scheme, service providers, located in India, would be rewarded under the SEIS scheme, for all eligible export of services from India.
    • SEIS was earlier termed as Served from India Scheme (SFIS).

    Eligibility

    • Service Providers of notified services, located in India are eligible for the Service Exports from India Scheme.
    • To be eligible, a service provider (Company / LLP / Partnership Firm) should have a minimum net free foreign exchange earnings of USD 15000 in the preceding financial year to be eligible for duty credit scrips.
    • For proprietorships or individual service providers, minimum net foreign exchange earnings of USD10,000 in the preceding financial year is required to be eligible for the scheme.
    • Also, in order to claim reward under the SEIS scheme, the service provider shall have to have an active Import Export Code (IE Code) at the time of rendering such services for which rewards are claimed.

    Back2Basics: Merchandise Exports from India Scheme (MEIS)

    • MEIS was launched with an objective to enhance the export of notified goods manufactured in a country.
    • This scheme came into effect on 1 April 2015 through the Foreign Trade Policy and was in existence till 2020.
    • It intended to incentivize exports of goods manufactured in India or produced in India.
    • The incentives were for goods widely exported from India, industries producing or manufacturing such goods with a view to making Indian exports competitive.
    • The MEIS covered almost 5000 goods notified for the purpose of the scheme.

  • Solar Energy – JNNSM, Solar Cities, Solar Pumps, etc.

    Rooftop Solar Scheme

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Solar Rooftop Scheme

    Mains level: Renewable Energy in India

    India has added 521 megawatts (MW) of rooftop solar capacity in the second quarter (Q2) of the calendar year (CY) 2021, a 53% increase than earlier quarter showing good signs of popularity.

    What is Solar Rooftop?

    • A solar photovoltaic (PV) system mounted on a rooftop of a building is a mini-power requirement or feed into the grid.
    • The size of the installation varies significantly depending on the availability of space, amount of electricity consumed by the property and the ability or willingness of the owner to invest the capital required.

    Why rooftop?

    • Rooftop solar with a storage system is a benefit for both, end consumers as well as discoms (power distribution companies).
    • A one-kilowatt (kW) rooftop system can produce three to five units of electricity a day.
    • The combination increasingly becomes cost-effective for electricity generation compared to the traditional grid supply and diesel generators.
    • In 2021, solar and storage will be cheaper than grid supply for most commercial and industrial (C&I) customers.
    • The increase in penetration of rooftop solar in the distribution grid will have a significant impact on the stability of the grid.

    A viable alternative

    • Most housing societies in urban India rely on diesel generators for power backup. However, as power availability improves in the country, diesel generators will become redundant.
    • The operational cost of diesel generators is quite high— R16-18 per unit against Rs 5-6 a unit for solar rooftop systems. So rooftop solar power makes financial sense.Solar rooftop is also a perfect solution for commercial and institutional buildings that operate mostly during the day.
    • Their rooftops can be utilized to generate electricity, and they can, partially or completely, replace diesel generators. This would also help them reduce their electricity bills.

    Question of energy storage

    • In order to integrate rooftop solar and electric vehicles, the grid needs to be flexible and smart.
    • Energy storage systems will play a key role in providing this flexibility by acting as a load when there is a surplus generation, as well as generating sources when there is a supply shortage.
    • There are two major methods of integrating battery storage into the electric grid:
    1. Front-of-the-meter (FTM): It is implemented at the utility scale, wherein the battery system is connected to the transmission or distribution network that ensures grid reliability. This happens on a considerably large scale (~MWh scale).
    2. Behind-the-meter (BTM): The other method is implemented at the residential and commercial/industrial level, mainly to provide backup during a power failure or to store excess locally generated energy from solar rooftop photovoltaic (PV) systems.

    India’s storage capacity

    • About 34 GW / 136 GWh of battery storage is expected to be installed by 2030, according to the Central Electricity Authority of India.
    • This capacity would be used for RE integration, demand-side and peak load management services.

    Storage challenges

    • The solar segment offers a huge market opportunity for advanced battery technologies.
    • However, manufacturers have some ground to cover in addressing technical limitations of batteries, such as charging characteristics, thermal performance and requirement of boost current to charge deep cycle batteries.
    • Since solar companies may directly procure batteries from manufacturers and require after-sale services and technical support, battery companies should have wider a presence to address these expectations.

    Other key challenges

    • Rooftop solar source doesn’t match the rise in renewable energy in India.
    • While industrial and commercial consumers account for 70% of total installed capacity residential consumers remain a big untapped potential to give the boost
    • Solar rooftops also face several challenges such as little consumer awareness, lack of innovative government policies or attention, bureaucratic hassles, and limited support from discoms.

    Way forward

    • Supportive policies and innovative technological approaches are needed for the sector to achieve its potential.
    • Indian policymakers need to plan for rooftop solar plus storage, rather than rooftop solar alone with the grid as storage (net / gross metering).
    • The declining cost of storage solutions, along with that of rooftop solar solutions, is likely to change the future of the Indian power sector.
    • Several countries such as Australia, the United States, Germany, among others have already endorsed solar power with battery storage.
    • Energy storage, therefore, represents a huge economic opportunity for India.
    • The creation of a conducive battery manufacturing ecosystem on a fast track could cement India’s opportunity for radical economic and industrial transformation in a critical and fast-growing global market.

  • Capital Markets: Challenges and Developments

    SEBI introduces T+1 Settlement System

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: T+1, T+2 settlement

    Mains level: NA

    The Capital markets regulator Securities and Exchange Board of India (SEBI) has introduced T+1 settlement cycle for completion of share transactions on optional basis in a move to enhance market liquidity.

    What is T+1 Settlement System?

    • T+1 means that settlements will have to be cleared within one day of the actual transactions taking place.
    • Currently, trades on the Indian stock exchanges are settled in two working days after the transaction is done (T+2).
    • In April 2002, stock exchanges had introduced a T+3 rolling settlement cycle. This was shortened to T+2 from April 1, 2003.

    What has Sebi allowed?

    • SEBI has allowed stock exchanges to start the T+1 system as an option in place of T+2.
    • If it opts for the T+1 settlement cycle for a scrip, the stock exchange will have to mandatorily continue with it for a minimum 6 months.
    • Thereafter, if it intends to switch back to T+2, it will do so by giving one month’s advance notice to the market.
    • Any subsequent switch (from T+1 to T+2 or vice versa) will be subject to a minimum period.
    • A stock exchange may choose to offer the T+1 settlement cycle on any of the scrips, after giving at least one month’s advance notice to all stakeholders, including the public at large.

    Why T+1 settlement?

    • Reduced settlement time: A shortened cycle not only reduces settlement time but also reduces and frees up the capital required to collateralize that risk.
    • Quick settlement: T+1 also reduces the number of outstanding unsettled trades at any instant, and thus decreases the unsettled exposure to Clearing Corporation by 50%.
    • Speedy recovery of assets: The narrower the settlement cycle, the narrower the time window for a counterparty insolvency/bankruptcy to impact the settlement of a trade.
    • Risk reduction: Systemic risk depends on the number of outstanding trades and concentration of risk at critical institutions such as clearing corporations, and becomes critical when the magnitude of outstanding transactions increases.

    How does T+2 work?

    • If an investor sells shares, settlement of the trade takes place in two working days (T+2).
    • The broker who handles the trade will get the money, but will credit the amount in the investor’s account only.
    • In effect, the investor will get the money only after three days.
    • In T+1, settlement of the trade takes place in one working day and the investor will get the money on the following day.
    • The move to T+1 will not require large operational or technical changes by market participants, nor will it cause fragmentation and risk to the core clearance and settlement ecosystem.

    Why are foreign investors opposing it?

    • Foreign investors operating from different geographies would face time zones, information flow process, and foreign exchange problems.
    • Foreign investors will also find it difficult to hedge their net India exposure in dollar terms at the end of the day under the T+1 system.
    • In 2020, SEBI had deferred the plan to halve the trade settlement cycle to one day (T+1) following opposition from foreign investors.

    Back2Basics: SEBI

    • The SEBI is the regulatory body for securities and commodity market in India under the jurisdiction of Ministry of Finance Government of India.
    • It was established on 12 April 1988 and given Statutory Powers on 30 January 1992 through the SEBI Act, 1992.

    Jurisdiction of SEBI

    • SEBI has to be responsive to the needs of three groups, which constitute the market:
    1. Issuers of securities
    2. Investors
    3. Market intermediaries

    SEBI has three powers rolled into one body: quasi-legislative, quasi-judicial and quasi-executive.

    • It drafts regulations in its legislative capacity, it conducts investigation and enforcement action in its executive function and it passes rulings and orders in its judicial capacity.
    • Though this makes it very powerful, there is an appeal process to create accountability.
    • There is a Securities Appellate Tribunal which is a three-member tribunal and is currently headed by Justice Tarun Agarwala, former Chief Justice of the Meghalaya High Court.
    • A second appeal lies directly to the Supreme Court.

  • Historical and Archaeological Findings in News

    What is Vishnuonyx?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Vishnuonyx neptuni

    Mains level: NA

    Between 12.5 million and 14 million years ago, members of a genus of otters called Vishnuonyx lived in the major rivers of southern Asia.

    Vishnuonyx neptuni

    • Vishnuonyx were mid-sized predators that weighed, on average, 10-15 kg.
    • Before this, the genus was known only in Asia and Africa (recent findings show that Vishnuonyx reached East Africa about 12 million years ago, according to the release).
    • Vishnuonyx depended on water and could not travel long distances over land.

    Why in news?

    • German researchers have discovered the fossil of a previously unknown species, which they have named Vishnuonyx neptuni, meaning ‘Neptune’s Vishnu’.
    • Fossils of these now extinct otters were first discovered in sediments found in the foothills of the Himalayas.
    • Now, a newly found fossil indicates it had travelled as far as Germany. ‘
    • The dispersal of Vishnuonyx otters from the Indian subcontinent to Africa and Europe about 13 million years ago. ‘
    • This is the first discovery of any member of the Vishnuonyx genus in Europe; it is also its most northern and western record till date.

    How did it travel as far as Europe?

    • According to the researchers, its travels over 6,000 km were probably made possible by the geography of 12 million years ago, when the Alps were recently formed.
    • These Alps and the Iranian Elbrus Mountains were separated by a large ocean basin, which would have made it easier for the otters to cross it.
    • Researchers believe ‘Neptune’s Vishnu’ first reached southern Germany, followed by Ancient Guenz and eventually, the Hammerschmiede.
