Tesla to build world’s biggest lithium ion battery in South Australia

Tesla’s billionaire founder Elon Musk will build the world’s largest lithium-ion battery to store renewable energy in South Australia in collaboration with Neoen, the French energy.

129MWh battery combined with a wind farm, is designed to improve the safety of electric power supply in South Australia.

On Friday, state PM Jay Weatherill confirmed the deal, which is a key element of the government’s $ 550 million energy plan.

The state government said musk confirmed its promise made on Twitter in March that it could deliver the battery within 100 days of signing the contract or that it would be delivered free.

Romain Desrousseaux, deputy general manager of Neoen, said that 129MWh, South Ion-lithium-ion become the largest in the world. The battery will be built near Jamestown in the middle of northern state, and will be paired to Hornsdale Neoen wind farm to ensure the stability of renewable energy in the network.

Muscle to the press in Adelaide on Friday that the project was not without technical difficulties, as it would be the largest installation of batteries in the world “by a significant margin.”

“When you do something three times bigger, it always works? We think this will be possible, but there is a certain risk,” he said. “We have confidence in our technology and system design.”

It was envisaged that this would help to stabilize the network and reduce prices for consumers.

“Basically, you can charge the batteries when you have an excess of energy when the cost of production is very low … and then discharge it when the cost of energy production is high, which effectively reduces the average cost for the end customer” , Said musk. “This is a fundamental improvement in the efficiency of the network.”

Muscle said a failure to deliver the project on time would cost the group about $ 50 million, although contract details were not revealed.

The battery is an essential part of the $ 550 million energy plan by the state government established after the state’s failure last year. Weatherill said, “I am very pleased to select Neoen and Tesla, whose expertise and global leadership in energy and renewable energy helps South Australia to take charge of its energy future.”

“The storage of the battery is the future of our national energy market and the eyes of the world follow our steps in this space.

“This historic agreement is more sustainable Tesla energy generator in South Australia, but will also have significant economic benefits.”

Repeated failures in SA since September have provoked a political fight over energy policy, accusing the failures of the federal government in the use of renewable technologies.

Following the most recent power outage in early February, the Australian energy market operator said there were many factors, including higher-than-expected demand.

Storing the battery through the network could help equalize price spikes, avoid power outages, and improve network reliability.

Tesla has recently completed the installation of an 80MWh battery battery grid in Southern California in just 90 days, expected at a cost of $ 100 million.

Tim Flannery, the Climate Council, said that South Australia was responsible for Australia’s transition to renewable energy technologies and storage.

“South Australia is addressing climate change and should be commended for its innovation and leadership because it transforms our energy system into clean, affordable, efficient and secure,” said Flannery.

LHC Physicists Unveil a Charming New Particle

Physicists using the experience of the Large Beauty Hatcher Collider (LHCb) at CERN in Geneva, Switzerland, have discovered a new type of heavy particles, they announced this week at a conference in Venice.

The particle, known as Xi-cc ++ (pronounced “ksi-CC plus-plus”), consisted of three small elementary particles called quark, in particular a “high” quark lighter than those found in protons and neutrons and two “Charm” quarks, which are the heaviest and most exotic variety.

(The terms “high” and “charm” are two of the six physical ‘models’ assigned to the quarks of masses and particles of varying charges).

The standard model of particle physics predicts Xi-DC ++ and many other possible particles with various configurations of the six known quarks flavors. But so far, such “doubly Haunted” particles had escaped conclusive detection.

Other studies of the new particle – and other members of the doubly enchanted particle family – could either strengthen the standard model or lead to new opportunities in particle physics.

Anyway, the new particle could be a tool to unlock a deeper understanding of the fundamental “strong” force that binds quarks together to form protons and neutrons, which in turn form atoms, planets, stars, galaxies, and people.
Any particles made from quarks are called hadrons. The world’s largest and most powerful particle accelerator, the Large Hadron Collider at CERN (LHC), these particles flow together in search of new particles and interactions.

The hadrons are divided into two large families: mesons, exotic particles with a quark and an antiquark; And baryons, particles composed of three quarks. The new Xi-cc of particles ++ is a baryone.

But because of its doubly enchanting character, it is almost four times heavier than the most well-known baryons, such as protons and neutrons, which are composed entirely of light quarks instead of heavy ones.

“Finding a doubly heavy quark baryon is of great interest as it will provide a unique tool to delve into QCD quantum chromodynamics [] – the theory that describes strong force, one of the four fundamental forces,” spokesman LHCb spokesman Giovanni Passaleva Said in a statement. “Such particles will help us improve the predictive power of our theories.”

Quark quill quills in protons and neutrons glide evenly around each other at almost the speed of light, which makes them very difficult to study. In a particle Xi-cc ++, the only high-speed quark light to beat around the heavier and slower heavy quark pair, creating an easier situation for doctors to investigate.

The situation, according to former LHCb spokesman and physicist Guy Wilkinson of Oxford University, is more or less analogous to a planetary system in which the light quark like a planet in orbit around a little star of massive stars.

Directed by Glasgow University physicist Patrick Spradlin, the LHCb team found evidence of more than 300 new particles in the data collected last year by experience, devastating their signals from a dense forest more common particles produced by proton collisions Of high energy in LHC.

Specifically, they sought a revealing particle “daughter” distribution, including other baryons and exotic kaone particles and pions produced by the decomposition of short X-DC ++ particles.

Observed distributions not only show that LHC collisions produce X-DC ++ particles, but they also highlight the other demands of other researchers investigators

Mars may be more toxic to life than we thought

Mars may be more toxic to life than we thought

Mars may be more toxic to life than we thought

Life on Mars … does it exist? According to the date on which the past came with the news of the red planet, we could probably be convinced anyway.

As we discovered more and more of the composition and dynamics of the planet Mars, it was not so much an emotion and disappointment with the likelihood that organic life could consume the planet.

The pendulum has returned to the ‘no’ side today with the publication of a study examining how a special type of salt on Mars interacts with ultraviolet radiation there.

Mars soil is surrounded perchlorates, an ion composed of a chlorine atom and four oxygen atoms and binds to a number of different elements to form various compounds.

It is classified as a salt, and is initially caused to hold between alien minds, as it significantly reduces the freezing point of the water, which means that the liquid H20 could exist on the surface. It can also be used to produce rocket fuel and oxygen, another advantage for future settlers.

Salt march

It turns out that these perchlorates are actually very toxic to life when they bathe in the UV light that bites Mars. Center for Astrobiology UK researchers at the University of Edinburgh have discovered a strain of bacteria commonly found in a spacecraft at levels of perchlorate and UV light found on the red planet and found that almost everyone died within a minute .

They treated this with several different types of perchlorate, and found similar results every time. By adding additional environmental factors found on Mars, such as low temperatures, additional minerals found on Mars and lack of oxygen have also failed to keep the bacteria alive.

This was a bit surprising to researchers because the strain of bacteria used, Bacillus subtilis, belongs to a genus that works well in the presence of perchlorates, as confirmed by studies of microbes in the terrestrial environment. These results were initially good news for researchers seeking extraterrestrial life, as they suggest that some life forms could survive in similar Martian conditions.

It takes more than salt

There are more on Mars than just the ground, and when Edinburgh researchers have added some other factors similar to those of Mars – UV in particular – the bacteria is dead in no time.

They believe it happens because ultraviolet light separates perchlorate molecules into reactive ions that wreak havoc on living cells. This hypothesis was supported by the observation that low temperatures, which slow chemical reactions, prolonged the life of the bacteria in perchlorate but still resulted in their deaths.

If they can not survive there, this greatly reduces the chances of finding life on Mars – a life-like organisms on Earth at least. The researchers published their findings Thursday in Scientific Reports Nature.

Although it is a stroke of luck to find life on Mars, there is at least an increase of the news: NASA regularly worried about the possibility of contaminating other planets with terrestrial bacteria, even going up to crash sensors in Saturn so that they do not collide with The moons of the planet.

If Mars is so hostile to bacteria they can not even take a minute Our fears of surface contamination could be solved.

Bank Audit Audit of NPA with Special Reference to Prudential Norms

Advances constitute greatest amount in the total assets of a bank ’s balance sheet and therefore, audit of advances becomes the most important component of bank audit. case an advance account is classified as NPA (Non- Performing Asset), primary responsibility of making adequate provision for diminution in value of advance is that of the bank management and the statutory auditors. It is, therefore, imperative for the statutory auditors, to have thorough knowledge of the norms prescribed by the Reserve Bank of India (RBI) in Master Circular – ’Prudential norms on Income Recognition, Asset Classification and Provisioning pertaining to Advances (IRAC Norms). The author in this article explains those aspects of the Master Circular regarding NPAs which are most relevant during the bank branch audit.

Overview

The prudential norms are formulated on the basis of objective criteria rather than on any subjective consideration. This has brought in uniform and consistent application of the norms and greater transparency in published accounts of banks. The latest Master Circular No. DBOD.

www.icai.org

No. BP.BC.9/21.04.048/2014-15 dated 1st July, 2014 issued by the RBI contains IRAC norms which are applicable for the statutory audit of banks for the year ending 31s,March, 2015. For the first time, the RBI has introduced new frame work for revitalisation of distressed assets in the above circular.

Audit of NPA would basically involve identification of an account as NPA, its correct classification, income recognition, provisioning, if an account is restructured and compliance of various conditions as enumerated in the Master Circular, etc.

  • Types of Assets

Standard Asset: An account is considered as standard asset when it is not non-performing and does not carry more than normal risk attached to the business.

Non-Performing Asset (NPA): An asset becomes NPA when it ceases to generate income for the bank. This would mean that an account would be classified as NPA on the basis of record of recovery rather than security charged in favour of the bank in respect of such account. Thus, an account would become NPA if interest charged to that particular borrower is not realised within the prescribed time frame despite the account being fully secured.

  • Identification of Account as NPA

The RBI has laid down undermentioned criteria for classification of various types of advances as NPA which is based on record of recovery:

  • Term Loan: Interest and/or instalment of principal remain overdue for a period of more than 90 days.

It is very important to note here that as per para

  • of the Master Circular, an account would be classified as NPA only if the interest due and charged during any quarter is not serviced fully within 90 days from the end of the quarter. For example, interest is charged on 30th November, 2014 in a term loan account. Now, if it is not serviced within 90 days from 31st December, 2014, then term loan account would become NPA, not otherwise.
  • Overdraft/Cash Credit: If an account remains out of order, it would become NPA. For this purpose, an account would be treated as ‘out of order’ if:
  1. The outstanding balance remains continuously in excess of the sanctioned

 

limit/drawing power for 90 days or more, or

  1. Even if the outstanding balance in the account is less than the sanctioned limit/ drawing power, there are no credits in the account continuously for 90 days as on the date of the balance sheet, or
  2. Credits in the account are not sufficient to cover interest debited during the same period.

As on 31st March, 2015, if any of the above criteria is satisfied, the account would be classified as NPA. Auditor should verify stock statement to check the correctness of drawing power and whether the same is calculated in accordance with the approved policy of bank. Auditor should not assume sanctioned limit to be the drawing power. There may be instances where drawing power would be less than the sanctioned limit. For example, sanctioned limit of an account may be ^25 lakh but the drawing power of the account may not necessarily be ?25 lakh and it could less than that. A CC/OD account which is classified as standard may get classified as NPA because of an error in calculation of drawing power.

  • Bills Purchased/Discounted: If the bill

purchased or discounted remains overdue for a period of more than 90 days from its due date.

  • Agricultural Advances: A loan granted for-
  1. Short duration crops will be treated as NPA, if the installment of principal or interest thereon remains overdue for two crop seasons.
  2. Long duration crops will be treated as NPA, if the installment of principal or interest thereon remains overdue for one crop season.

For the purpose of these guidelines, “long duration” crops would be crops with crop season longer than one year and NPA date would depend on crop cycle, which is

A credit card account will be treated as NPA, if the minimum amount due, as mentioned in the statement, is not paid fully within 90 days from the next statement date. The gap between two statements should not be more than a month.
