Toshiba plans rollout of entirehome battery system

first_img More specifically, on a full charge, the Toshiba system is reportedly capable of powering lighting equipment (100W), refrigerator (160W), TV (150W) and personal computer (30W) for about 12 hours. Recharging takes about five hours. A rapid-charge mode cuts it down to two hours. The output power of the eneGoon is 3.0kVA, which Toshiba claims is the highest output power of a home-use electricity storage system in the industry The system’s key component is Toshiba’s “SCiB” lithium-ion rechargeable battery which has a capacity of 6.6kWh, considered relatively high for a home battery system. Since 2010, Toshiba has promoted its ability to put battery technology on the fast track with the SCiB, a rechargeable lithium-ion battery. The company says its advantages include minimal capacity loss, a high level of safety, and long life of more than 6,000 charge-discharge cycles, along with high power output performance.Toshiba Lighting and Technology will launch eneGoon in November in Japan. There was no information on pricing at the time of this writing. According to Tech-On, the eneGoon’s maximum power output is 3.0kVA and it can power appliances up to 200V. The product is going to appear in November in Japan but that does not deter outsiders from taking an interested look at what Toshiba has developed, at a time when better solutions for storage batteries that can cost less and do more, longer, are goals everywhere. © 2012 Explore further Toshiba’s SCiB rechargeable battery selected for new electric vehicles This document is subject to copyright.

Citation: Toshiba plans rollout of entire-home battery system (2012, September 17) retrieved 18 August 2019 from (—Japan’s residents well know the difficulties of power outages; unsurprisingly, efforts toward smarter solutions for backup power options are top priority for R&D at companies like Toshiba. The company plans to roll out a home storage battery system that can keep appliances running for a good part of the day. Toshiba Corp and Toshiba Lighting and Technology Corp have developed a storage battery system that makes use of the company’s technology for rechargeable batteries. The system is called eneGoon, and it can do the work in the event of a power shortage to power up the gamut of frequently used household appliances Toshiba says eneGoon can powering a home dweller’s refrigerator, TV, PC, and lights for 12 hours on a full charge.last_img read more

Energy analyst proposes injecting carbon dioxide into deep sea ravines for permanent

DOI: 10.1016/j.egypro.2017.03.1686 (—New Zealand energy analyst Steve Goldthorpe has published a paper in the journal Energy Procedia suggesting that carbon dioxide pulled from the atmosphere (or scrubbed from coal plant smoke stacks) could be stored permanently in deep ocean trenches. Once there, he notes, the gas would become a liquid denser than ocean water, which would cause it to fall naturally to the ocean floor, creating an underwater lake. More information: Steve Goldthorpe. Potential for Very Deep Ocean Storage of CO 2 Without Ocean Acidification: A Discussion Paper, Energy Procedia (2017). DOI: 10.1016/j.egypro.2017.03.1686AbstractCarbon Capture and Storage (CCS) is an essential contributor to the mitigation of climate change. CCS will require vast CO2 storage capacity. At present only geological storage is being considered. This paper revisits an alternative CO2 storage possibility in enclosed basins on the deep and very deep ocean floor. For example, the Indonesian Sunda trench, the Japanese Ryukyu trench and the Puerto Rico trench are more than 6 km deep. If liquid CO2 were to be placed in such a trench, it would be 7% more dense than seawater and could remain permanently as a lake of liquid CO2 on the ocean floor, possibly becoming a solid hydrate over time which could inhibit mixing between the stored CO2 and ocean currents. At depths greater than about 4 to 5 km metres, seawater is under-saturated in calcium carbonate, so ocean ecosystems are significantly different. Any impact on deep marine fauna would need to be investigated. The London Dumping Convention has provisions for disposal of material into the ocean provided the absence of adverse effects can be proven. Deep ocean CO2 entrapment is more certain than geological CO2 storage in deep aquifers. A CO2 delivery concept by ship and vertical pipe is suggested for exploratory trials, with subsea pipelines for permanent installations, which might be much cheaper than geological CO2 storage. There is vast capacity for storage of CO2 in the world’s very deep ocean trenches. The Sunda trench below 6 km has the capacity to accommodate 19,000 gigatonnes of liquid CO2, which is greater than the CO2 yield from all currently known global fossil fuel reserves. The Puerto Rico trench has capacity for 24,000 Gt of liquid CO2 deeper than 7 km. Enclosed basins of limited area could easily accommodate captured CO2. China has the largest potential demand for CO2 storage from power generation and industrial sources, which could be 3 Gt per year by 2050. The Ryukyu trench, which is 700 km from the Chinese coast and is in Japanese water, has two sections deeper than 7 km. Those sections of the Ryukyu trench would have the capacity to accommodate all the CO2 captured in China at 3 Gt per year for over 200 years. In the event that very deep ocean storage of CO2 is found to be practicable and acceptable, the minimum practical depth would need to be determined as a criterions for acceptable additional storage locations. For consideration, there is an enclosed basin on the floor of the Mediterranean Sea 60 km off Southern Greece, with capacity for 84 Gt of CO2 deeper than 4.5 km. Also, there is an enclosed basin in the Arabian Sea, 320 km south west of Karachi, with capacity for 86 Gt of CO2 deeper than 3.5 km. The potential storage of CO2 in such locations would be temperature dependent. The global CCS community has previously considered ocean storage of CO2 on the basis of ultimate dissolution and dispersion of CO2 in ocean water. Those studies have dismissed ocean storage as environmentally unacceptable due to ocean acidification. This paper postulates that very deep ocean trenches (>6 km) and deep ocean floor depressions (>4 km) are environments for CO2 storage, where permanent storage without dissolution, acidification or adverse effects on fauna may be possible. The purpose of this paper is to pose the question “Why not?” to the CCS community and to suggest that active research is timely. In order to prevent serious changes to our planet, most scientists agree that we need to stop pumping greenhouse gases, particularly carbon dioxide, into the atmosphere—and we should probably start trying to remove at least some of what we have already put there. But where would put it? We cannot just dump it somewhere, because it is a gas and would simply make its way back into the atmosphere. Some have suggested injecting it into spent natural gas wells or other underground vacancies. Goldthorpe suggests that perhaps the ocean would be a better option, noting that at depths of 3000 meters, the density of carbon dioxide is greater than that of ocean water, which means it would sink. Ideally, it would sink into a hole of some sort so that it would not spread across the ocean floor. Ocean trenches, he notes, could serve that purpose. They would fill like an empty bucket with water here on land, creating a lake of carbon dioxide. He adds that it is possible that over a long time period, the carbon dioxide would solidify.Goldthorpe takes his idea even further by offering some possible sites—he used Google Earth to check for suitable candidates. He notes that Sunda trench, which is 6 kilometers below the surface in an area south of the Indonesian archipelago would be a good choice. He’s calculated that it could hold 19 trillion tonnes of liquified carbon dioxide, which, he notes, is more than all of the carbon dioxide that humans have injected into the atmosphere to date. He notes also that the idea is not out of the blue—natural carbon dioxide lakes already exist on the ocean floor. Other possibilities might include the Japanese Ryuky trench or the Puerto Rico trench.Goldthorpe concludes by acknowledging that much more study would have to be done before serious consideration, particularly to prevent the top portions from spreading or causing an increase in ocean acidity.

Experts Say Emotion Recognition Lacks Scientific Foundation

first_img Read the whole story: ACLU A new study, however, strongly suggests that these products are built on a bed of intellectual quicksand. The key question is whether human emotions can be reliably determined from facial expressions. “The topic of facial expressions of emotion — whether they’re universal, whether you can look at someone’s face and read emotion in their face — is a topic of great contention that scientists have been debating for at least 100 years,” Lisa Feldman Barrett, Professor of Psychology at Northeastern University and an expert on emotion, told me. center_img Emotion recognition is a hot new area, with numerous companies peddling products that claim to be able to read people’s internal emotional states, and AI researchers looking to improve computers’ ability to do so. This is done through voice analysis, body language analysis, gait analysis, eye tracking, and remote measurement of physiological signs like pulse and breathing rates. Most of all, though, it’s done through analysis of facial expressions.last_img read more

KMC set to form Hardship Redressal Committee

first_imgKolkata: The Kolkata Municipal Corporation (KMC) is all set to form ‘Hardship Redressal Committee’ (HRC) for examination of applications by the tax payers who plan to seek relief in case of excessive hardship in paying off property tax under Unit Area Assessment (UAA) system.A senior official of the KMC said HRC has been formed for providing relief to tax payers who face excessive hardship in paying property tax within the ambit of Section 173 B of KMC Act 1980. Also Read – Heavy rain hits traffic, flights”As per provisions of the act, the committee after receiving the application in writing by the tax payer concerned, may review the amount payable for the property or may realize the sum in installments.The Committee is also empowered to make recommendations for any relief to the KMC for consideration,” the official said.The formation of HRC has already been passed at the Member Mayor-in-Council’s (MMiC) meeting of the civic body that was held in June. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThe eight-membered team will have MMiC (Solid Waste Management) Debabrata Majumder as the Chairman. The matter will be passed at the monthly meeting of the KMC on May 20.It may be mentioned that the KMC had extended the deadline for payment of property tax under UAA system for a period of six months with effect from April 1.The last date for paying property tax under UAA was earlier announced till March 31. Inspectors from the civic body’s assessment department has been travelling from door to door of the residents and handing out forms of UAA and also guiding them on how to pay tax under UAA. “An unnecessary scare about the new property tax calculation method has kept assessees from embracing the new UAA method. We need to put an end to this irrational fear and for this we are taking all measures,” the official maintained.KMC had introduced UAA in April 2017 but the response was lukewarm with only 50,000 of the 2.75 lakh assessees opting for it and submitting the applications till the middle of March.Sources in the assessment department said civic authorities has set a fresh target of Rs 998 crore in property tax for the next fiscal that began from April 1.last_img read more

Central files on Netaji may not unravel his disappearance Kingshuk Nag

first_imgThe Centre’s act of declassifying secret files on Netaji Subhas Chandra Bose may not help in unravelling the mystery surrounding his disappearance, noted journalist and author Kingshuk Nag has said.“Prime Minister Narendra Modi has just promised, he is yet to act on that. Even if all the central government files are declassified, I am not sure, if they will have all the answers that people are seeking to know about Netaji,” Nag said during the launch of his book ‘Netaji: Living Dangerously’ on Tuesday.  Also Read – Rain batters Kolkata, cripples normal life“I doubt if the files will have all the information, because some of the important files may be missing, may be doctored long before Modi became the prime minister,” said the Prem Bhatia Memorial Award winner. Following a meeting with a host of Netaji descendants and historians, Modi in October announced the Centre will declassify files related to Bose from January 23 – his birth anniversary. The Prime Minister also assured he would request foreign governments, including Russia, to declassify files related to Netaji available with them. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedNag, who in his book has dealt about the various theories surrounding Netaji’s disappearance following an alleged air crash in Formosa (now Taiwan) on August 18, 1945, claims the answer to Bose’s disappearance lie hidden in secret files with the Russian, British and the Japanese governments. “The Indian government files may mostly carry certain passing references about Netaji. The real mystery behind his disappearance may be revealed only if the files with the Russian, British and Japanese governments are declassified,” Nag said. Eminent historian Hari Vasudevan said the Modi government ought to have sought the services of experts for the process of declassification of over 120 files said to be with the various central departments, including the PMO. “We don’t know what files will be classified so it is difficult to say whether they will be able to answer the questions that we all have been seeking. But, I don’t think it is adequate that files are just randomly declassified without allowing experts, or historians to ask questions,” Vasudevan said.last_img read more

A Memory filled Monsoon

first_imgWith his unique concept and power to toy with human psyche he attempts to unveil buried feelings of a person’s mind. Amit said, “Memories are transcendental by nature. They act as time machine that cradles a human mind between now and then, hither and thither with memories flashing in pieces”. He explains, these memories could be both sweet and sour but it is something that connects to ones individuality and something one has absorbed from their surrounding. The exhibition will portray the state of calmness and peace through mix medium of art and will be showcased at DSIIDC, Narela, Industrial Area from June 18 and will conclude on June 30. Also Read – ‘Playing Jojo was emotionally exhausting’Through this show the artist has tried to arrange the scattered puzzle pieces of memories to understand the subconscious state of mind which results in understanding one’s own self. Every touch of the brush hovers between reality and fantasy world, balancing every virtual image that restrains the power to grasp an impression and make it everlasting on canvas.  Serenity is a series conceived, nurtured and delivered from the womb of memory, inspired by anything and everything against any limits. Artist Amit Dutt believes in immeasurable flow of thought process and hence his paintings offer a panoramic view to the observer. The figurative paintings in this solo show will showcase the impetuous state of human mind and will portray the different shades of human consciousness. Each of his painting consists of vibrant and sober colors blend fairly in a unique way which builds a serene characteristic in the art. They are loud enough to pour the heart and soul of a spectator with thoughts but are peaceful to look at due to its subtle nature. The contrasting shades of color every painting has, narrates a different story. But the message perceived by each the viewer vary in many ways.last_img read more

Tips to avoid Indoor air pollution

first_imgIndoor air pollution is very much real and it can be five times or more worse than outdoor air pollution. From everyday consumer products and household habits such as paints, pet allergens to cooking gas, can be an additional source of air pollution. So, what now and how do we shield ourselves? Experts say, “According to the World Health Organization (WHO), global air pollution database released in Geneva, India has 14 out of the 15 most polluted cities in the world in terms of PM 2.5 concentrations. It said 7 million people die every year because of outdoor and household air pollution…Reports like these suggest that the impact of pollution on human health is fatal. Air pollution has impact on most of the organs and systems of human body. The lung is one of the major sites of interaction with environmental particulates that causes and aggravates many respiratory diseases like COPD, asthma, and lung cancer”. Also Read – Add new books to your shelfHere are some tips which can help to avoid indoor air pollution:4Say no to scented incense sticks and candles: After reading this you might think twice before lighting up those decorative candles or using agarbattis. Studies suggest incense sticks and scented candles release undesired chemicals that can cause serious health problems like skin allergies and even heightens risk of respiratory cancer 4Say yes to some greenery: Yes! Plants are your best friends. They provide fresh oxygen to our lungs and planting a few indoor plants in your home with help you breathe clean and off course it gives that extra punch to your indoor décor. So, go ahead, buy some beautiful indoor plants and give your house a chic look. Also Read – Over 2 hours screen time daily will make your kids impulsive4Remove carpeting if possible: Those aesthetic carpets and rugs can actually be a source of indoor air pollution. Carpets can capture a lot of pollutants such small dust particles, food which fall on the floor, pet hair, dust mites, pesticides, cockroach allergens and other dirt. These pollutants may become airborne while vacuuming or during renovations. Children are more exposed to these pollutants are they tend to play on the carpet. 4Indoor smoking is deadly: Avoid smoking Indoor. It affects not only the smoker but also people around them. While we are all aware about the harmful effects of smoking, it is deadlier indoor. Since there is no space for the smoke to go out so you tend to inhale the same air repeatedly, harming your nostrils and lungs. 4Ensure good ventilation: Proper ventilation in your house will prevents air pollutants from affecting you and your family’s health. Not only that, having a proper flow of air inside your home can help you get rid of all the unwanted smells arising from cooking or from carpets. Also, allergens such as dusts, pollen, and other irritants which tends to get trapped inside your house can be removed to a large extent if there is a proper ventilation.4Give away your plastic habits: Plastics are a major cause of air pollution. The by-products of plastics called microplastics are small pieces of plastic between the size of 0.1 micron to 5mm in diameter. These microplastics are immensely harmful to our health. Shockingly microplastics have found its way to our homes also. Their contributors can be simple things like erosion of synthetic carpets, synthetic clothing or cosmetics. 4Get an air purifier: Air purifiers are the best way to clean the indoor air. In addition to investing in your health it can prevent microplastics, allergies and impure air from harming you and your dear ones.last_img read more

LeBron is the new NBA establishment Phil Jackson Deal with it

first_imgIn a recent interview, Phil Jackson made comments referring to LeBron’s business team as a “posse.” Colin doesn’t think the comments were racially motivated, but he does believe they were intentionally disparaging and demeaning, and Jackson is too smart to not know how they would land.Sports, like politics, is all about power, and the establishment is always in fear of losing it. LeBron James and his business associates have upset the traditional NBA power structure and made him the most powerful person in the NBA. NBA archetypes like Phil Jackson and Pat Riley are clearly struggling with losing their power within the league to players, like LeBron. Colin says deal with it, times have changed. (Maverick Carter joins the show for an exclusive interview to give his reaction to the comments)“LeBron is the new establishment. Deal with it.”Colin has had it with the College Football Playoffs, and the idea that only conference champions can make the playoffs. This year, Ohio State is headed for an 11-1 season, with their only loss coming on the road at Penn State, in which they led most of the game. But, they could find themselves on the outside, looking in at the Final Four because Penn State holds the tiebreaker.Colin says enough is enough, he’s in favor of Ohio State making the Final Four if they win out because they’re the second best team in the country. In practically every other sport, teams don’t have to win their conference to make the playoffs. College football shouldn’t be any different.“In the NFL. In the NBA. In the NHL. In Major League Baseball. You can be a wild card team and win the World Series, a Super Bowl, a Stanley Cup. Why be paralyzed by all these qualifiers? Why even have a committee? Just check the boxes.”  Colin is on the record saying that the Big Ten, as a conference, has better coaches than the SEC, and are gaining in the arms race for the best college football conference. But, the SEC is still lapping the field in terms of NFL talent, and it’s not even close.  In last night’s Monday Night Football game between the Bengals and the Giants, SEC alums on both teams made all the big plays. Eli Manning, Odell Beckham Jr., Landon Collins, Jeremy Hill and A.J. Green, to name a few. The SEC may not have the best coaches, but they’re still lapping the field in terms of NFL talent. It’s not even close.“Don’t kid yourself. This sport is overwhelmingly run by one conference. It’s in the South, the SEC.” Guests:Ty Law – 3-time Super Bowl champ is in-studio to talk Patriots, what it was like playing for both Belichick and Pete Carroll, if the Steelers problems are the fault of the coaches or the players, what he saw in a young Tom Brady that showed he would be successful, and the cutthroat business of the NFL for a veteran player at the end of his career.Jason McIntyre – Founder of the Big Lead and co-host of Speak for Yourself is in-studio to discuss Phil Jackson’s “posse” comments, how he thinks the College Football Playoff will play out, why he’s in favor of an 8-team playoff, and his take on Westbrook’s struggles without Durant in OKC.Maverick Carter – Founder of LMR Marketing and business associate of LeBron James joins the show to give his reaction to Phil Jackson’s comments referring to LeBron’s business team as a “posse”, how LeBron changed his feelings about forgiving Dan Gilbert for his comments and returning to Cleveland, and when LeBron might stop by to sit on the couch for an interview in The Herd.Chris Broussard – FS1 NBA Insider is in-studio to discuss Colin’s interview with Maverick Carter and Phil Jackson’s comments, why they were disparaging, how LeBron has changed the power structure of the NBA, and whether there is any truth to the rumors that Klay Thompson is on the trading block in Golden State.Charles Haley – NFL Hall of Famer, 5-time Super Bowl Champ, and author of Fear No Evil: Tackling Quarterbacks and Demons on My Way to the Hall of Fame, joins the show to talk about his battles with PTSD, bipolar disorder and depression after his playing career, how he overcame it, if he thinks it affected his playing career, if he felt his play was overlooked by the media, and which coaches he had the biggest impact on his life.last_img read more

Pats fan who pulled Steelers hotel fire alarm to police Im drunk

first_imgThe night before the Patriots drilled the Steelers in the AFC Championship game, someone pulled the fire alarm at the Pittsburgh hotel. It wasn’t Bill Belichick, he apparently had an ironclad alibi.According to the Massachusetts State Police, 25-year old Boston area native Dennis Harrison is the guilty party. He’s a Pats fan.Per the Boston Globe, Harrison was at a house party at a friend’s place in Revere, when he was dared to pull the fire alarm at the Hilton Boston Logan Airport Hotel, where the Steelers were staying. Harrison, who was a couple of sodas deep, accepted the dare.He and a friend drove to the hotel, but that’s where the master plan went awry. Harrison entered the hotel and pulled the alarm, but when he exited the building to escape the scene, his getaway driver had ditched him. Good friends don’t always make good accomplices. Advertisement Harrison was discovered wandering around the perimeter of the building and was eventually ID’ed by police as the suspect.When asked why he did it, Harrison fired off a classic response, stating,“I’m drunk. I’m stupid. I’m a Pats fan.” You have to give the guy points for honesty.On Monday, Harrison appeared in East Boston Municipal Court, and plead not guilty to disorderly conduct, disturbing the peace, and setting off a false fire alarm. He was released on his own recognizance.Maybe next time he plans a crime, he should use his underachieving, genius friend, who secretly solves complex math equations while working the night-shift as a janitor at MIT. He’s wicked smahhht.last_img read more
