What happens when a plastic city burns Most modern couches are basically blocks of gasoline. Thursday, January 16, 2025 Welcome to The Weekly Planet, a newsletter that provides a guide for living through climate change. Did someone forward you this newsletter? Sign up here. Zo? Schlanger Staff writer The Threat of Plastic (Ariel Fisher) View in browser As flames rip through Los Angeles County, burning restaurants, businesses, and whole blocks of houses, it’s clear that the threat of urban fire has returned to the United States. But this time, the urban landscape is different: Modern homes are full of plastic, turning house fires into chemical-laced infernos that burn hotter, faster, and more toxic than their predecessors. Firefighters are warning that the smoke pouring out of neighborhoods in Southern California is a poisonous soup, in part because of the ubiquity of plastics and other petrochemical products inside them. “It’s one of the reasons why we can’t put firefighters in front of these houses,” the Cal Fire battalion chief David Acuna told me on Monday. After any lifesaving work has been done, keeping firefighters in the toxic air is too great a risk. Very few fixtures of the modern home are entirely free of plastic. If your couch is like many available on the market today, it’s made of polyester fabric (plastic) wrapped around polyurethane foam (plastic). When polyurethane foam burns, it releases potentially deadly hydrogen-cyanide gas. Perhaps those plastic-wrapped plastic cushions sit on a frame of solid wood, or perhaps the frame is made from an engineered wood product held together with polymer-based glues (plastic). Consider, too, the ubiquity of vinyl plank flooring, popular for its resistance to scuffing, and vinyl siding, admired for its durability. Then there is foam insulation, laminate countertops, and the many synthetic textiles in our bedding and curtains and carpets. Nearly all house paint on the market is best understood as pigment suspended in liquid plastic. Research has long shown that exposure to the tiny particles that make up wildfire smoke is a major health hazard; as I’ve written before, wildfire smoke kills thousands of people prematurely each year and is linked to a range of maladies. Burning trees release gases such as carbon monoxide and carbon dioxide, along with tiny solid particles called PM2.5, which can penetrate deep into a person’s lungs and circulate in their blood stream, and are linked to heart and lung problems, low birth weight, preterm birth, and cognitive impairment. A burning town takes many of the chemical hazards of a burning forest and adds in a suite of new ones, Nadine Borduas-Dedekind, an atmospheric chemist at the University of British Columbia, told me. As structure fires eat through the plethora of materials inside a home, they can release not just hydrogen-cyanide gas but also hydrochloric acid, dioxins, furans, aerosolized phthalates, and a range of other gaseous contaminants broadly known as volatile organic compounds. Some may be harmless. Others are associated with health problems. As gas-detection technology improves, “we’re discovering new molecules of incomplete combustion that we didn’t know existed,” Borduas-Dedekind said. “When you’re burning a home or an entire neighborhood, we don’t have a handle on the breadth of VOCs being emitted.” And many of these can react with one another in the atmosphere, creating yet more compounds. Whereas N95 masks are good for filtering out the fine particles associated with fire smoke, they do nothing for these gases; only a gas mask can filter them out. Plastic is made from petroleum, and petroleum burns fast and hot. A retired Maryland state fire marshal told Newsweek that, from a fire perspective, a typical couch is akin to a block of gasoline. Acuna invited me to think of placing a log on a campfire: It takes some time to heat up, charring first. It eventually ignites and becomes a steady fire, releasing its heat at a slow, consistent rate over, say, 20 minutes. If you threw a two-liter soda bottle on a campfire (wh

Die Burger berig vandag dat Eskom geen aanduidings van sabotasie gekry het soos wat De Ruyter beweer het nie. Ek skat hulle wou nie tekens sien nie. Ek herinner my dat ons by verskeie gelenthede foto's van afgesaagde stoom en ander pype gesien het! Ek hoop André help hulle reg. PW

https://mybroadband.co.za/news/security/576690-eskom-prepaid-electricity-system-breached.html Eskom prepaid electricity system breached By Hanno Labuschagne An investigation has uncovered that security controls in Eskom’s online vending system (OVS) were breached and the system was used to generate illegal electricity tokens in bulk. The power utility suspects some of its own staff may be involved in the crime and has appointed an external IT company to conduct a forensic probe into the breach and to make recommendations on fixing the OVS’s vulnerabilities. The OVS was first implemented by Eskom in 2008 to combat so-called “ghost” vending of electricity tokens sold through offline credit dispensing units which were stolen or lost. The OVS facilitates the dispensing of prepaid electricity via virtual channels including banking apps, remote terminals such as ATMs, and other vending stations. “The system vends electricity tokens from the main Eskom central server through approved national vending agents using a secure backend in real-time,” the power utility explained in its 2024 integrated report. “The system should not permit any external vending channel to vend a token if the vending agent cannot communicate with the Eskom server or cannot be authenticated via the secure protocol.” “Once the token is generated, it is encrypted, stored in the OVS database, and sent to the customer by the vending agent.” “Once the customer enters the token, the prepaid meter decodes the 20-digit token using the Standard Transfer Specifications security protocol, and only accepts the token if all the related information matches the OVS system and is accepted as valid.” “If the information does not match, the token will be rejected.” However, these controls were not sufficient, and Eskom strongly suspects that some of its own staff had successfully colluded with illicit operators and compromised the OVS to facilitate the creation and sale of fraudulent prepaid electricity tokens, both for key revision number (KRN) 1 and KRN 2 meters. An infographic comparing the basic functioning of Eskom’s discontinued offline and online vending systems. Concerns over sole supplier’s conflict of interest The utility’s Audit and Risk Committee (ARC) acknowledged that the prepaid electricity ecosystem exposed Eskom to various risks, including the creation and use of illicit tokens from which the uitility derives no revenue. In addition, Eskom relies on a single supplier for the OVS’s software and hardware solutions. The supplier is also a distributor of the tokens, creating a possible conflict of interest. The ARC provided oversight of the progress of the investigation into the breach of the OVS and the implementation of action plans. The latter includes improved cybersecurity controls to prevent the creation of illicit tokens as far as possible. ARC also requested that all service-level agreements in the prepaid electricity ecosystem be reviewed and that the related risks be evaluated and appropriately addressed. “This could include the possible exit of agreements where the risk is considered intolerable, as well as implementing a process where national vending agents must provide assurance reports on controls and submit independent confirmation that their systems are secure and that they are only selling valid prepaid electricity tokens,” Eskom’s integrated report said. In his introductory comments at Eskom’s 2024 annual financial results presentation on Thursday, 19 December 2024, Eskom board chairperson Mthetho Nyati said the issue contributed to the delay in the publication of Eskom’s results. Eskom typically announces its annual results in the third quarter of each year. Nyati explained that Eskom was unable to reliably estimate its potential financial obligation from the exposure that illicit tokens could be used in the future. There is a high level of uncertainty around the number of illicit prepaid electricity tokens generated through OVS that remained in circulation and compatible with Eskom meters after the KRN rollover. Eskom said it would provide

https://www.nytimes.com/2024/12/19/business/gm-china.html China has long, and persistently, prioritized electric & hybrid vehicles G.M. Led in China for Years. Here’s How It Ended Up 16th in Sales. General Motors has gone from market leader to also-ran in the world’s largest car market, stymied by its own missteps and Chinese policies that favored its local rivals. Listen to this article · 12:56 min Learn more Share full article 165 Bringing American auto technology to China included training employees in partnership with a local carmaker. Workers in Shanghai examined a Buick’s undercarriage in 1998.Credit...Greg Girard/Contact Press Images, for The New York Time By Keith Bradsher Keith Bradsher, who has covered General Motors’ China business since 2002, reported from Shanghai. Dec. 19, 2024 阅读简体中文版閱讀繁體中文版 General Motors was a pioneer in China, where for a quarter-century the company drew enormous profits and vied with Germany’s Volkswagen as the top seller of cars. Those days are over. G.M.’s sales in China have entered a death spiral, falling 42.5 percent in the first 11 months of this year. The company now ranks 16th by sales. The dizzying collapse of its China business forced G.M. to take a roughly $5 billion charge against profits this month. It was a drastic comedown for the company, which started in China in 1996 with an initial investment of $350 million and went on to build a network of factories, churning out vehicles and sending billions in profits to its headquarters in Detroit. G.M.’s early China executives were highly responsive to the unique characteristics of the market. They built bulky minivans with lots of sparkling chrome to appeal to leaders of the state-owned companies that were big customers. They sold Buicks, a faded brand in the United States that still had cachet in China. For rural farmers, G.M. offered vans and pickup trucks with flimsy seats and no air-conditioning that cost only $5,000. Advertisement SKIP ADVERTISEMENT In many ways, the story of G.M. in China tracks the experience of all foreign automakers in what is now the world’s largest car market. China allowed foreign carmakers like G.M. into the country only as part of a publicly stated, long-term policy to gain technology and build its own globally competitive industry. Government leaders were also intent early on to shift away from cars that needed gasoline, which China mostly imports, and toward electric cars powered by energy sources at home like coal, solar and wind. G.M. executives foresaw China’s strength, particularly in electric cars. “China is well positioned to lead in this,” David Tulauskas, an early G.M. director of China government policy, said in a 2009 interview. But after years of success, G.M. has found it increasingly difficult to compete with Chinese rivals or adapt to the rise of electric cars. Image Potential buyers looked at an inexpensive Wuling minivan in 2005 at a dealership near the company’s factory in Liuzhou, China. G.M. had invested in Wuling three years earlier.Credit...Chang W. Lee/The New York Times Government policies that forced G.M. into joint ventures with Chinese companies meant that G.M. ended up teaching much of what it knew about car manufacturing to local rivals that now outsell it. Advertisement SKIP ADVERTISEMENT Since 2008, Beijing has collected taxes totaling more than 100 percent on large, imported cars and sport utility vehicles. The taxes are so high that G.M. does not even try to import some models, like the Cadillac Escalade. That full-size S.U.V. starts at $87,595 in the United States but costs $186,000 including tax in China, when purchased through an import agent. Electric cars made in China face only a 13 percent tax. In addition to wielding tax policy at foreign carmakers, Beijing limited or blocked government subsidies for cars built by foreign companies. Partly as a result, G.M. has not competed effectively in battery electric vehicles and plug-in hybrid cars. These models together accounted for 52.3 percent of the Chinese market in November, the China Passenger Car Associatio

https://www.rethinkx.com/faq-and-mythbusting/what-is-the-role-of-conventional-nuclear-power-in-our-energy-future "The primary shortcoming of nuclear power is that it is extremely expensive compared to all other energy options. This is because nuclear fission is an inherently dangerous technology, which necessitates very costly safeguards during construction, operation and decomissioning, as well as for the radioactive fuel and waste. "The cost of electricity from a new nuclear power plant ranges from three to over thirty times more than the electricity from solar, wind and battery power (SWB) "The cost of nuclear power has risen over 25% in the last 10 years, while in the same period the cost of solar power has fallen almost 90%, the cost of wind power has dropped fallen nearly 50% and the cost of batteries has fallen roughly 90%."
