The Perpetual Coral Cemetery is part of the restoration and restoration of the marine environment. “As soon as I received his ashes from the crematorium, I suddenly thought about what it would be like to let him lie on the bottom of his favorite ocean, becoming a beautiful part of the ocean ecosystem,” recalls Brawley. Efforts to save corals Eternal Reefs is a funeral company based in Florida (USA). It is famous for the most “beautiful” burial method, which contributes to the regeneration of the marine ecosystem. The beginning of Eternal Reefs is quite simple. In the late 1980s, a pair of scuba diving friends, Don Brawley and Todd Barber, of the University of Georgia noticed that coral reefs were deteriorating. They decided to do something to stop the decline and quickly recover. After much discussion and design, Brawley and Barber were satisfied with the initiative of Reef balls. They use natural materials that both have good cohesion and attract marine life, molded into an upside-down, hollow bowl shape, with many circular holes all around. These holes allow water to pass through, avoiding being knocked over by the waves and allowing animals to get in and out. A bowl of coral can weigh from 800 – 4,000 pounds (360 – 1,800kg), sink and settle on the seabed forever. Its structure acts as a home for small animals, immediately attracting them to swim in. After just a few weeks, the artificially implanted coral tissues on the surface of the bowl grew, turning the bare bowl frame into a lively, eye-catching cluster of coral. Sea creatures flock to each other, forming diverse natural habitats. Immediately after its introduction, the coral bowl has become the most effective solution to save the ocean ecosystem. As of 2020, more than 70 countries have applied it to about 5,000 marine restoration projects, placing over 750,000 bowls across the ocean. Perfect submerged cemetery Family members are encouraged to make their own bowls of coral reefs. In early 1998, Brawley’s father-in-law, Carleton “Petey” Glen Palmer, died. During his life, Palmer was extremely fond of the sea, always wishing after death to still see the ocean floor. “Spray my ashes into the sea, where there are plenty of snapper and grouper,” he left a testament to Brawley. While sitting in memory of his father-in-law in front of the urn recently received from the crematorium, Brawley suddenly had a strange idea. That is to mix the ashes with the coral bowl casting mixture and start immediately. On May 1, 1998, Brawley buried his father-in-law and nine pioneers with a bowl of coral in Sarasota Beach, Florida. The first human ashes coral cemetery was born, after only a few months, it became a beautiful part of the underwater landscape. Or believe, sea lovers race to enjoy diving. Former marines, marine environmentalists, fishermen, divers, etc. who are about to be “near land far from heaven” warmly welcome Eternal Reefs. The sea grave coral bowl quickly became popular. Eternal Reefs allows and encourages bereaved families to participate in the process of making coral bowls, carving tombstones, launching… The location of the sea grave coral bowl is the reef area that has been designated for ecological restoration. In addition to the burial coral bowls, ordinary coral bowls are also placed, serving the regeneration of the marine environment. “2nd Life” After only a few months, the bowl of sea coral has turned into a home for a large number of sea creatures. On average each year, Eternal Reefs contributes 120 – 150 bowls of sea coral in thousands of artificial coral bowls. Depending on the size, the cost for a bowl of sea grave coral ranges from 4,000 – 7,500 USD (about 91 – 170 million VND). Eternal Reefs does not limit the number of ashes in a bowl of coral, so the bereaved can choose to bury one or more people. They are also allowed to attach memorial objects to the coral bowl, but must ensure that it is environmentally friendly. During the process of bringing the bowl of coral to the sea and launching it, the bereaved family can combine a farewell ceremony. Once placed on the seabed, the bowl of sea coral will stay in place forever. Relatives of the deceased have the right to visit, but are not allowed to move or collect. In recent years, in addition to those who work in the sea-related industry, Eternal Reefs also welcomes many other customers. Among these, there are many people who are parents who have met the fate of “silver-headed and green-headed”. They are too pitiful, want their lost child to have a second life and find salvation in the bowl of coral reefs. Compared with 750,000 bowls of artificial coral placed all over the seabed, the bowl of sea grave coral only accounts for a small number. However, Brawley believes it will make a big difference in burial customs around the world. In fact, the world is filled with more and more people who don’t want to rest in traditional ways. With the exception of marine grave coral bowls, many other ecological burial methods have also captured the attention. For example, composting corpses into soil, hydrolysis, releasing ashes into space…

Hashima Island (Japan): This island has been abandoned since 1974. At the end of the 19th century, this place used to be a busy coal mine. Hashima can be seen as a symbol of the industrialization process in Japan. However, oil gradually replaced coal in Japan in the 1960s, which was the main cause of the end of the coal mining industry activities on the island. Image: Getty. Today, Hashima is left with only ruins, gloomy. The special space of the island makes it chosen as the filming location for many movies such as Skyfall, Attack on Titan… The island was officially opened to tourists in 2009. In 2015, UNESCO decided to make it public. Hashima as a World Heritage Site. Photo: Mail Online. North Brother Island (USA): Less than 2 km from Manhattan (New York, USA), this abandoned island has caused a lot of curiosity for half a century. The island’s past is associated with disease, death… From the years 1880 to 1943, the New York government used the island as a place to isolate patients with infectious diseases. Typhoid Mary Mallon – the first person in American history to contract typhoid but show no symptoms – was once isolated here until her death. Image: Cubed. Currently, the government does not allow people to come here for the purpose of tourism, sightseeing… Only a few with special reasons are allowed to visit this island. To get here, you need to take a boat across the East River. A lot of police appear in this area. According to Insider, this may be due to the island’s location near the Rikers Island prison. In addition, the police are also wary of people who intend to approach North Brother Island. Photo: Atlas Obscura. Hirta Island (Scotland): Many traces indicate that humans lived on Hirta Island in the St. Kilda from prehistoric times. However, all of them had to be relocated in 1930 because of the risk of starvation and extreme weather conditions. Image: Sobt. According to Atlas Obscura, since the beginning of the 20th century, the life of the people on the island has been greatly disturbed when delegations from the mainland appeared. They brought with them many interesting cultures and new diseases. In 1930, after the death of a young woman from appendicitis and pneumonia, the islanders were terrified. They asked to be evacuated and live on land. The evacuation took place on August 29, 1930. Before boarding, each person left a plate of oats and an open Bible in the house. Photo: Hudu Trip. Herschel Island (Canada): In 1826, the first Europeans set foot on the island. At that time, the island became a whaling place for about 2,000 people. By the early years of the 20th century, however, whaling had begun to subside. The last family living on Herschel Island left in 1987. Since then, the government has established the Qikiqtaruk Territorial Park with an area of ​​​​the entire island. Image: Wikiwand. Holland Island (USA): The first people to settle on the island began around 1600. Over time, fishing and agriculture developed, attracting many people and sailors to settle. In its most glorious period, the island had about 70 buildings including houses, shops, schools, post offices, churches, medical stations… Photo: Sometimes Interesting. However, the erosion caused Holland Island to gradually disappear from the map. The people tried to save the island in many ways but all failed. This forced them to leave the island to find safer places. Some still cling to the belief that mother nature will “forgave” them. However, a hurricane in 1918 caused the family to finally pack up and leave. In October 2010, the last house on the island collapsed because it could not withstand the natural conditions. By 2012, the island was completely eroded. Photo: TypePad.

Design of a waste treatment line for the Vietnamese market with 3D technology at the Belgian company Menart. His work is part of the waste treatment project to make compost at the Residential and Industrial Solid Waste Treatment Area in Vinh Tan Commune, Vinh Cuu District, Dong Nai Province, which is carried out by Belgian company Menart and Co. Sonadezi Environment Joint Stock Company in Dong Nai province. Sharing with Vietnam News Agency correspondent in Belgium, Mr. Anthony said the design must be based on actual research and survey. He went to Vietnam and went to Dong Nai to review the field conditions at the place where the waste treatment plant will be built and then returned to Belgium, designed with 3D technology, the line will be installed to suit the conditions. Vietnam’s tropical climate. Some details are produced on-site by Menart company, others are sent to Vietnam for partners to do. The equipment will then be transported from Belgium to be assembled at a waste treatment plant for operation. Meanwhile, at the factory, Menart’s engineers are installing and testing waste sorting and composting equipment. This is the second production line that Menart is about to hand over to Sonadezi for deployment in Vietnam. In the equipment factory of the domestic waste treatment line of Menart Company, Belgium. Mr. Mot, an experienced technician, said that last year, he was sent by the company to Vietnam and to Dong Nai to prepare for the trial operation of the waste treatment plant. He stayed in Dong Nai for 6 months, with Vietnamese colleagues installing lines and training operators to prepare for the trial run of the plant in November 2020. Menart is a private company established in 1961 specializing in the design, construction and installation of equipment for organic fertilizer production and environmental protection waste treatment. With a team of highly qualified engineers and technicians, Menart provides equipment and solutions for many fields, especially environmental protection and clean agricultural production. Currently, Menart’s network of activities covers 60 countries on 4 continents including Asia, Europe, Africa and America. According to Ms. Bérengère Menart, General Director of Menart, the company has been working with Vietnam since the late 90s of the last century in the field of environment. In Vietnam, Menart provides equipment for waste treatment plants in Dong Nai, Soc Trang, Kon Tum, Ha Tinh, Thai Nguyen, Ha Nam provinces to turn waste into compost for agriculture. Waste sorting and treatment line manufactured by Menart company for Vietnam market. The composting waste treatment plant at the domestic and industrial solid waste treatment area in Vinh Tan commune, Vinh Cuu district, Dong Nai province is invested by Sonadezi Environment Joint Stock Company and also provided by Menart Company. device. The 7.1-hectare plant was put into trial operation late last year with a capacity of 450 tons/day, operating 8 hours/day. The operation process consists of 4 main stages: waste sorting, aerobic composting, ripening, and creating refined humus. About 80% of the organic waste received will be treated as compost; about 15% of inert waste after burning is buried in hygienic burial pits; About 5% of nylon bags are recovered, recycled and reused. Currently, Menart continues to complete the garbage sorting equipment, composting machines, rotary machines, and composting equipment to hand over to Sonadezi to serve the expansion of the Vinh Tan waste treatment plant. Ms. Bérengère Menart strongly believes in the prospect of cooperation in this field with Vietnam. She said: “Vietnamese people and local authorities will raise awareness of environmental protection, reduce the amount of untreated waste into the environment and thus contribute to improving the quality of life.” She affirmed and wished to continue expanding cooperation in technology transfer to Vietnamese partners in the fields of environment and agriculture. With projects implemented in Vietnam, Menart is contributing to the local government to solve the management and treatment of waste, a hot issue today, due to the rapid urbanization process.

Panoramic cave area Panga ya Saidi, Kenya, where ancient tomb is excavated Despite being home to the earliest indications of modern human behavior, early evidence of African burials is scarce and often ambiguous. Therefore, very little is known about the origin and development of the continental burial practices that gave birth to mankind. Pang ya Saidi has been an important site for the study of human origins since excavations began in 2010 as part of a long-standing collaboration among archaeologists from the Max Planck Institute on the Faculty. Study Human History (Jena, Germany) and National Museum of Kenya (Nairobi). Repeated excavation seasons at Pang ya Saidi now help establish it as a key site on the East African coast, with a special 78,000-year record of cultural, technological and iconic activities. original human. Parts of the child’s bones were first found during the excavation at Pang ya Saidi in 2013, but it wasn’t until 2017 that the feature of the small bone-filled pit was completely revealed. About three meters below the existing cave floor, the shallow, round hole contains bones that have decomposed tightly and are very difficult to decompose, and should be stabilized and plastered at the scene. New findings in the laboratory After being reassigned, the remainder was taken to the National Museum in Nairobi and then to the National Research Center for Human Evolution (CENIEH) laboratories in Burgos, Spain, for further excavation and analysis. Two teeth were exposed during the initial laboratory excavation, leading researchers to suspect that the remains could be human. Subsequent studies at CENIEH confirmed that the teeth belonged to a child between 2.5 and 3 years old, later nicknamed ‘Mtoto’, meaning ‘child’ in Swahili. Through months of intense excavation in CENIEH’s laboratories, spectacular new discoveries have been made. Professor María Martinón-Torres, director of CENIEH, explained: “We started to explore parts of the skull and face, with the intact joint of the lower jaw and some uneven teeth. The articulation of the spine and ribs is also surprisingly preserved, even preserving the curvature of the chest. It showed that it was an intact burial and the decomposition of the body took place in the hole where the bone was found. ” Microscopic analysis of the bones and surrounding soil confirmed that the body was quickly covered after burial and decomposition took place in the pit. In other words, Mtoto was intentionally buried shortly after death. The researchers also suggest that Mtoto’s bent body, found to be reclined to the right with the knees pulled towards the chest, represents a tightly wrapped burial with deliberate preparation. Martinón-Torres noted that this community may have performed some form of honor ceremony. The burial was different among modern humans and Neanderthals The child’s date (Mtoto) is 78,000 years ago and it is the oldest known human burial site in Africa. Later periods from the Stone Age of Africa also included many children, perhaps signaling special treatment of children’s bodies in this ancient period. Human remains have been found on an archaeological level with mid-African Neolithic stone tools, a distinct type of technology believed to be more involved than hominins. Ndiema noted: “The link between this child burial tool and the Stone Age played an important role in proving that Homo sapiens was the exact producer of these particular industries, in contrast to other hominin species ”. Professor Michael Petraglia of the Max Planck Institute in Jena noted: “The burial of Pang ya Saidi shows that the dehumanization of the dead is a cultural practice shared by Homo sapiens and Neanderthals. This finding raises questions about the origins and evolution of corpse burial rituals between the two human species is closely related and the extent of this behavior is far from that of people today.

Produced | Tiger Sniff Technology Group Author | See you Head Picture | Visual China The female car owner’s rights defense incident at the Shanghai Auto Show pushed Tesla to the forefront. Yesterday afternoon, Tesla emailed the female owner’s data about the car in the accident, and announced the data 1 minute before the accident. However, according to the latest news from Elephant News, the female car owner was still in detention and could not receive outside news. Her husband, Mr. Li, believed that Tesla’s public data violated personal privacy. Tesla explained this one minute before the accident: “When the driver stepped on the brake pedal for the last time, the data showed that the vehicle speed was 118.5 kilometers per hour. Within 2.7 seconds after the driver stepped on the brake pedal, the maximum brake master cylinder pressure was only 45.9 bar. After that, the driver increased the stepping on the brake pedal, the brake master cylinder pressure reached 92.7bar, and then the forward collision warning and automatic emergency braking function was activated (the maximum brake master cylinder pressure reached 140.7bar) and played After the ABS was applied, the system recorded the occurrence of the collision. After the driver stepped on the brake pedal, the vehicle speed continued to decrease. Before the collision, the vehicle speed was reduced to 48.5 kilometers per hour.” Although Tesla claims that vehicle data is encrypted and stored and cannot be directly read, modified, or deleted. When product disputes arise, Tesla will provide true and complete vehicle data in accordance with the law, but there are still voices questioning the authenticity of the data. A brake technology expert told Hu Xiu, “This kind of Excel table data is easy to be tampered with.” “The data is meaningless, it is impossible to determine whether the data has been tampered with, and more information about Bosch brake systems needs to be disclosed.” Zhang Xiang, a member of the new energy and intelligent networked automobile industry expert think tank of the Ministry of Industry and Information Technology, believes that in general, data should be uploaded in real time The data that is hosted by a third party or government agency and then released from the third party’s server is more credible. According to relevant experts interviewed by China Daily, there are three possible reasons for Tesla’s “brake failure”: One is the poor interaction between the car pedal and the iBooster brake-by-wire system, or the vehicle control center makes a mistake in judging and sends wrong instructions to the brake system, causing the brake plate to lose control. The second is that the iBooster system may have a very small possible design flaw; the third is that Tesla’s AutoPilot system and the iBooster system may have a very small matching flaw. According to the experience of another Zhang Che who advocated Qi (a pseudonym), he had twice responded to software problems with the customer service and asked to check the background data, but the other party’s reply was: too much background data, one minute of data It takes a long time to watch. “It’s not that they can’t find the problem, but they don’t act. Every time, they tell me to come back next time if there is a problem.” In addition, Tesla also provided a set of vehicle conditions 30 minutes before the accident: “The driver drove the vehicle normally, with more than 40 records of depressing the brake pedal, and the vehicle exceeded 100 kilometers per hour several times. And the situation of multiple braking stops.” Generally, brakes will have “thermal decay” problems. If the owner frequently re-presses the brakes, the overheated braking force will be severely reduced. However, it cannot be directly inferred that the main cause of the accident was the improper operation of the car owner. What is the final result of this rights protection storm requires more investigations. Without accurate and true data, all speculations are just conjectures. Female car owners are not alone. Since Tesla entered China in 2014, it has encountered various complaints every year. The female car owner just brought to the spotlight in an unexpected way the defects of product quality and after-sales service that had been concealed by Tesla’s aura for many years. How high is Tesla’s failure rate? Data shows that the number of Tesla Model 3 failures is as high as 236. This means that on average, every new Model 3 will have 2.36 failures within 2-12 months. The calculation method of this value is: the number of failures in one hundred vehicles = the total number of failures in the corresponding car system ÷ the sum of all the people participating in the evaluation × 100, which represents the number of failures per one hundred vehicles in a new car within 2-12 months, including failures , Abnormal noise, inconvenience and other problems. Compared to Xiaopeng P7’s 180, ideal ONE’s 134, Weilai ES6’s 56, and BYD Han’s 55, Tesla’s 100-car failure rate is significantly higher than these competing products. After Zhang Qi got the new car Model 3 in June last year, she often encountered some problems-for example, a new car of 350,000 drove on the road, sometimes shaking like a domestic car of tens of thousands of dollars; driving to work in the summer morning, the car will A layer of water mist appeared because the car automatically adjusted the air conditioner to a very low level, and it lasted all night; while driving in winter, the air conditioner only blows cold wind; sometimes the ears of the car cannot be turned on. This is nothing. Zhang Qi called the customer service before driving for repairs. The other party told him that the ball joint (also called universal joint, a kind of ball connection to realize the power transmission of different shafts) Mechanical structure) also repair him. “I wasn’t grateful to him at the time, it just made me think, why didn’t I say it early and recall it early? I only said it when I came to repair it? This attitude is very irresponsible.” Zhang Qi thought she was a very stubborn person before. People are very good at defending their rights, but facing Tesla’s after-sales service, they have no temper at all. The new car started to have various problems in less than a month. Zhang Qi has gone to repair 4 times so far, and the air conditioner has been overhauled 3 times. The first two times, the Tesla maintenance staff told him that there was no problem. Until the third time, the car screen displayed: “Due to a system failure, the temperature holder is unavailable”, the maintenance staff took it seriously. After changing the hardware, the air conditioner can be used later. The automatic control is still inaccurate, “Blow cold air when hot air should be blown”. Zhang Qi’s first three maintenance settlement statements At the end of March this year, when Zhang Qi drove this Model 3 off the elevated road, she smelled a pungent burning smell of the car. He and his friend sitting in the passenger seat were in a cold sweat. They thought it was a battery problem and the car might explode. They quickly parked the car on the side of the road for ventilation and called Tesla maintenance personnel. Two hours later, the maintenance personnel arrived at the scene, pulled the car to the maintenance point, and gave a “no problem” inspection result. During the overhaul, Zhang Qi once went to the car to pick up things. He found that his usual car phone charging cable was scorched. He asked a friend who worked in a car company to find out that this might be due to unstable battery, unstable voltage, and hot. There is a problem with the control system, etc., but Tesla inspectors still said that the car is okay and did not explain clearly-what faults will cause the data line to be burnt? What faults can cause the car to smell burnt? Compared to the car owner who has had a serious traffic accident, Zhang Qi is relatively lucky, but he has not dared to drive a Tesla since then. According to incomplete statistics from the Beijing Intelligent Vehicle Industry Innovation Center, Since 2013, Tesla has had hundreds of traffic accidents worldwide, resulting in a total of 175 deaths. According to statistics from the National Highway Traffic Safety Administration, Tesla has had 200 traffic accidents caused by “out of control” in the United States. Loss of control mainly refers to sudden acceleration, deceleration, and brake failure or steering wheel failure. In China, more than 20 Tesla vehicle accidents have appeared in the news in the past year. Although the number of traffic accidents cannot infer the direct fatality rate of Tesla, it can at least reflect that Tesla does have some unforeseen safety hazards. As Tesla’s sales increase, users have a deep understanding of the problems that arise during the use of vehicles. From the number and reasons of the recalled vehicles, we can also see the quality defects of Tesla vehicles. Among the many domestic new energy vehicle brands, Tesla has the largest number of recalls in the first quarter of this year. According to the announcement issued by the State Administration of Quality Supervision and Administration, a total of 5 new energy vehicle companies need to recall a total of 83,800 vehicles. Including 36,100 Tesla Model S and Model X, accounting for 43.1%, as well as BAIC New Energy’s EX360 and EU400 pure electric vehicles totaling 32,000, and Xiaopeng G3 vehicles totaling 13,399. Tesla’s latest recall of vehicles is mainly to update the software and replace the visual computing module in the central display (including the 8GB eMMC multimedia memory card). The eMMC cards of Model S and Model X produced before March 2018 experienced cumulative wear and tear, It will cause the central control screen to continue to be black. The central control screen integrates the most basic controls of the vehicle, including temperature, navigation, prompt sounds, etc., and most of the functions of the assisted driving system also need to be displayed on the screen. Although eMMC failure will not directly cause danger to the vehicle’s driving performance (acceleration, braking or steering), the software version of the vehicle is running too early, and the eMMC fails, the reversing image will not be displayed, and the external turn signal will not be able to be displayed during subsequent driving. Lights up, and even the defogging and defrosting functions of the windshield cannot be used. With this product issue alone, Tesla was required by the National Highway Traffic Safety Administration (NHTSA) in the United States to recall more than 130,000 Model S and Model X vehicles. Earlier, the German Automobile Administration (KBA) had also requested Tesla to recall about 12,300 Model X vehicles because of the shedding of the molded structure of the car body. In China, in addition to the recall, the relevant regulatory authorities have also interviewed Tesla twice, once in March last year, because some of the Model 3 vehicles should be equipped with HW3.0 chips (Tesla self-developed self-driving chips) , But only used HW2.5; the second time was in February this year, mainly for problems such as abnormal acceleration, battery fire, and remote vehicle upgrades. Why does Tesla always have problems? “Tesla’s current situation is that there are obstacles in the front and chasing after. The market can’t wait for Tesla to hand over a perfect product. If it waits for him to find out all the hardware and software problems, not only the capital can’t wait, but the users Can’t wait, the company has already closed down.” Zhang Xiang said. Tesla has actually passed the stage of building a car (Roadster) and building a good car (Model S), and now Tesla needs to build more good cars (Model 3). In the first two stages, Tesla relied on extreme technological innovation and cost control to highlight the auto market that has been dominated by established automakers for many years and gain a small market share. But in order to gain a firm foothold in the market before the auto giants increase their investment in electrification and intelligence trends, Tesla must rely on selling more products to stabilize the basic market in order to survive. Tesla has been accelerating its expansion in the past two years, building more super factories to expand production capacity and entering more emerging markets. This kind of speeding expansion is obvious in China-8 months to complete the construction of the factory and the off-line of the white body; last year, more than 410 super charging stations and more than 4,000 super charging piles were built in the country; last year, the production capacity was 150,000 vehicles. To achieve 550,000, it has tripled. Shanghai Tesla Factory During the production ramp-up period, Musk is also very clear about the problems behind it. He once said frankly in an interview at the beginning of the year that consumers are not advised to buy vehicles that are in a state of ramping production. “Either buy them at the beginning or wait until the production stabilizes.” Because it is difficult to guarantee that when the output rises sharply, It can achieve perfect details. For example, during the speed-up production process, it takes an extra one to two minutes for the vehicle paint to dry, but in fact there is not enough time to dry the paint. Although this is only an example of non-core components, it can at least show that there are still many omissions in Tesla’s manufacturing process. In Musk’s own words: “Yes, our production is like hell.” In the “Tesla China Chaos Revealed” released by Pinwan, it was mentioned that in order to complete the production, unqualified parts and components were installed on new cars; in order to make these products leave the factory, the solution was very simple and rude– Lower the factory standard. This kind of chaos in the production process is actually because Tesla pursues too much speed, and does not have the time and energy to confirm whether every detail is in place, and to carefully examine the possible omissions and omissions in the vehicle production process. Another point that causes product quality problems is cost control. Musk’s way of doing things is to achieve the best results at a very low cost. Zeng Yuqun, chairman of the Ningde Times, once complained, “Musk has been talking about cost issues all day, and I told him that I will definitely have a solution.” In addition to finding lower-priced suppliers, Tesla’s cost-saving method is actually to reduce unnecessary parts and reduce the cost of core components through system design and independent research and development. According to the dismantling of a Model 3 by the Zhihu Disassembly Laboratory, Tesla has done a lot of “cut corners” to reduce costs. “Switching from Model 3 to a minimalist interior to integrate the lights, rearview mirrors, and entertainment systems into the central touch screen, Tesla’s material cost is 1,000-2,000 yuan less than the competition. Take the 12.3-inch instrument as a For example, if the controller is included, the cost of this component is more than 1,000 yuan. Although the cost of the central control is saved, it increases the user’s interaction cost and sacrifices a certain degree of safety. …… The other is the highly integrated electrical architecture. Model 3 and Model Y divide the left, front, and right body controllers and the central computing unit by location. Although the unit cost of the controller has risen, the overall cost has dropped a lot due to the reduction in quantity. It is estimated that The saved material cost is equivalent to the latest smart phone. ” Tesla’s independent research and development of core technologies, such as chips, autopilot systems and other products, can reduce the occurrence of “stuck necks”, and the cost can also be greatly reduced, but the risks are also increased because of the products or technical routes independently developed by Tesla. Both require a certain amount of time for market verification. A typical example is that Tesla’s driverless technology mainly adopts the visual recognition route, which is to install a large number of cameras and sensors on the car to form a perception layer to identify and distinguish the environment around the car. Another technical route is the lidar route. For example, Xiaopeng, Weilai, Huawei, Uber and Baidu Apollo all choose to use lidar. The reason Tesla chose to take a different path is that it is too expensive. A set of lidar requires an additional nearly 50,000 yuan. Musk once bombarded lidar: “Stupid X only uses lidar!” Although lidar is more expensive, As long as the object exists, it can be detected without being affected by weather, light, etc. Truss once exposed the “ghost phenomenon”. For example, when a car drives to an unmanned cemetery, he perceives a lot of pedestrians around him; there is no car in the front and back, but it senses that there is a car. These are actually algorithmic flaws and cannot be quickly reacted in a special environment. For Tesla, it will take a long time to ensure that the error rate of the entire system is negligible. Write at the end The turmoil that Tesla is facing today is actually the sharp feedback from the market on the quality of its products and services. Tesla needs to divide responsibility and set standards for serious accidents. Regarding the rights protection of female car owners, although Tesla’s current attitude is to fully cooperate with third-party inspections. But Zhang Xiang said, “ At present, there is no third-party organization in the world that can clearly analyze the traffic accidents of smart cars. . Smart cars include a perception layer, a decision-making layer, and an execution layer. At present, third-party inspection agencies can only detect fuel vehicles. For the perception layer and decision-making layer, you need to get the schematics and software codes, and then get them one by one. Analysis, the workload behind this is huge. ” Exploring the truth and investigating responsibility is one direction, and the other direction is that we should think about why there is almost no third-party organization that can analyze the causes of traffic accidents in smart cars clearly? Why is the judgment standard for traffic accidents in smart cars still stuck in the era of diesel engines? When thinking about these issues, some people in the industry also gave concrete feasible solutions. The CEO of Ideal Motors wrote on Weibo that regarding ADAS and brake failure issues, government regulatory agencies can put forward the following regulatory requirements: 1. Vehicles with ADAS must be equipped with a driving recorder as standard; 2. When recording, the screen must display whether ADAS is running or not; 3. In addition to the display of the ADAS operating status, the corresponding basic working status of the accelerator, brake, and steering under the ADAS status should also be displayed. Human driving also displays the working status of these. He believes that this solution is not technically difficult, but it can provide relatively important evidence to reduce the difficulty for car owners to obtain evidence and the probability that manufacturers feel wronged. “If the car factory cheats here, it will directly stop the qualification for production and sales.” Do you have any constructive opinions behind the female car owners’ rights defense incident?
