Awesome | the first time in the world! The "tram" that only discharges water began to operate in Tangshan.

  Cctv newsYesterday, it was the first in the world.Hydrogen fuel cell tramPut into commercial operation in Tangshan, Hebei Province. The biggest feature of this tram is thatThe only substance discharged is water., to achieve the real "zero-emission”。

  This is also the first commercial operation of a hydrogen fuel cell tram worldwide, marking a major breakthrough in the field of new energy rail transit in China.

  The only emission of hydrogen fuel cell technology is water.

  Hydrogen fuel cell technology is the mainstream direction of global clean energy development and utilization.Power generation through the direct electrochemical reaction of hydrogen and oxygen is the reverse process of electrolyzing water, with high energy density, low noise and no pollution, and the highest temperature of power generation reaction does not exceed 100℃.No nitrogen oxides are produced, and the only emission substance is water, which is a real "zero emission".

  "zero emission" of pollutants from hydrogen fuel cell trams

  After more than four years of research, CRRC Tangshan Company took the lead in breaking through a series of key technologies such as fuel cell/supercapacitor hybrid traction and control for the first time in the world.The developed tram completely eliminates catenary and pantograph.(electric equipment for electric traction locomotive to obtain electric energy from catenary is installed on the roof of locomotive or motor car), which fills the gap in this field.Realize "zero emission" of pollutants and "net-free" operation in the whole process.

  Hydrogen fuel cell tramAdopting the world’s most advanced 100% low floor technology, the floor of the carriage is only 35 cm away from the track surface, and there is no need for a platform.; The minimum turning radius is only 19 meters, and the track can be directly laid along the existing urban roads, driving and stopping on the ground, so that passengers can easily ride.

  The car is equipped with a wireless wifi network system that can last for 40 kilometers.

  The Tangshan industrial tourism route uses hydrogen fuel cell trams.There is no need to set up catenary and install the third rail (power supply rail) and charging pile along the way. The whole operation of the line is 13.84 kilometers, and the tram only needs 15 minutes for rapid hydrogenation at a time, with a sustainable running speed of 40 kilometers and a maximum running speed of 70 kilometers per hour.

  This tram adopts 2-car, 1-trailer and 3-car grouping, with 66 passenger seats and a maximum passenger capacity of 336. The grouping and passenger capacity can be flexibly increased according to operational requirements. The car is equipped with a wireless wifi network system, and passengers can freely access the network.

The United States intends to strengthen legislation and law enforcement to standardize AI development

 ChatGPT, a chat robot developed by OpenAI, has risen rapidly, attracting a large number of fans, and at the same time attracting many competitors including Budd chat robot of Google. The picture shows the seminar on ChatGPT organized by the media service of public education school (data photo).

  In a recent report, the US Capitol Hill website pointed out that the explosive growth of generative artificial intelligence (AI) such as ChatGPT, and the resulting confusion such as the proliferation of false information, prejudice, and changing the labor structure, triggered the concerns of the US federal government. Lawmakers and regulators hope to take concrete actions to eliminate these concerns.

  Cause two key problems

  The Capitol Hill website reported that the development of AI may cause two key problems.

  On the one hand, the recent rise of generative AI tools has brought problems related to the spread of false information. On the other hand, AI that powers automation systems may lead to discrimination.

  The British magazine New Scientist also pointed out that ChatGPT and other chat bots often make factual mistakes, quote completely fictional events or articles, fabricate sexual harassment scandals and falsely accuse real people in cases. The use of ChatGPT has also led to data privacy scandals, involving the disclosure of confidential company data. In addition, images, audio and even videos generated by AI may also lead to large-scale "deep fraud" information, which is proved by the arrest of former US President Trump and the false AI composite photos of Pope Francis wearing fashionable white down jackets.

  The call for strengthening law enforcement is rising.

  The US Federal Trade Commission, the Civil Rights Department of the Ministry of Justice, the Consumer Financial Protection Bureau and the Equal Employment Opportunity Commission (EEOC) recently issued a joint statement saying that in view of the increasing use of AI in a series of services, from housing to medical care, they promised to strengthen the enforcement of existing laws, including aiming at solving the possible discrimination of AI and formulating new regulations on development rules.

  Charlotte burrows, president of EEOC, said that the use of advanced technologies, including AI, must comply with federal laws.

  Of course, the joint statement of these institutions mainly focuses on automated systems that use AI, rather than generative AI like ChatGPT.

  Even so, the website of Capitol Hill pointed out in the report, with the soaring popularity of ChatGPT and other chat bots, Google and other companies are constantly launching new products that compete with them. In addition, a group of entrepreneurs including Tesla and Twitter CEO elon musk are also rushing into the industry, which may lead to noise and turmoil, which also highlights the urgent need for policy makers to take relevant measures.

  To cope with the risks brought by AI, the US Congress will weigh the formulation of new laws and regulations, and institutions should also increase the enforcement of existing laws. Because even where existing laws are applicable, it may be difficult to enforce these laws because of the way the AI system works. For example, algorithmic recruitment tools may lead to discrimination, but it is difficult for employees to know whether they have been systematically discriminated against. Therefore, the problems that institutions need to solve are not only how to apply the law, but also how to deal with the challenges brought by the law enforcement process, and how these AI systems will affect the real world.

  Christine Clark, Assistant Minister of Justice in charge of civil rights affairs, also stressed that AI poses a great threat to all kinds of discrimination problems in today’s society, which need more in-depth research and review by policy makers and others.

  Safety management is imperative.

  Earlier this month, US senators announced a proposal to establish a framework for AI regulation, aiming at improving transparency and accountability. In addition, legislators are also prepared to take action to put pressure on the industry on the risks related to the rise of AI technology.

  The Senate Intelligence Committee recently wrote to the CEOs of ChatGPT developers OpenAI, Metauniverse Platform Company, Google, Anthropic and Microsoft, asking them how to deal with security risks when developing large-scale AI models.

  The letter wrote that with the increasing use of AI in most fields and the possibility of the steady integration of large-scale language models into a series of existing systems from medical care to financial sector, it is urgent to emphasize the security issues in the use of AI.

  In response to questions raised by some senators about how to use AI, a spokesman for the American Consumer Technology Association said that the association has been "contributing to the formulation of AI policies, standards and frameworks" with its members.

  Craig Albright, vice president of the American Software Alliance in charge of US government relations, said that Congress can require companies to formulate risk management plans, conduct risk assessments on high-risk use of AI, and define what high-risk cases are, while companies need to conduct impact assessments and design assessments to ensure that they do the right thing.

The world is competing to develop AI technology.

Along with various AI models competing to bloom, there is also a crazy influx of capital; As major companies increase the protection of their products, transparency is declining; The powerful ability and wide application of AI have also attracted the attention of policy makers in various countries, and have introduced relevant policies to protect its development.

  A heavyweight product in the field of artificial intelligence, "You sing and I debut". Open AI GPT-4 ushered in the "first show"; Google launched a test version of the chat robot "Bard". Before that, the company had already launched the medical large-scale language model Med-PaLM, as well as the large-scale language models PaLM API and MakerSuite;. Anthropic, an artificial intelligence startup, also released Claude;, a product similar to ChatGPT, on the 15th. Coincidentally, China Tsinghua University launched ChatGLM, a bilingual dialogue robot.

  AI technology ushered in the spring of "letting a hundred flowers blossom". In the report on the 22nd, Physicist Organization Network listed some trends worthy of attention in the AI field: with various AI models competing to bloom, there is also a crazy influx of capital; As major companies increase the protection of their products, transparency is declining; The powerful ability and wide application of AI have also attracted the attention of policy makers in various countries, and have introduced relevant policies to protect its development.

  Deployment is on the rise.

  In November last year, ChatGPT was born, and AI once again took the center of the technology stage.

  Just two months later, ChatGPT has more than 100 million monthly active users, making it the fastest growing consumer application in history. Earlier this month, OpenAI released the ChatGPT API, which will lower the threshold for developers to integrate ChatGPT into their own applications and services.

  OpenAI emphasized that some companies including fresh e-commerce platform Instacart, cross-border e-commerce platform Shopify, photo sharing application Snap, word recitation application Quizlet, etc. have taken the lead in accessing ChatGPT API to improve the efficiency and experience of customer service, marketing and education.

  In the past week, ChatGPT and other technologies have further accelerated the pace of "attacking the city": at present, the American software service company Notion, the social question and answer website Quora and the search engine DuckDuckGo have integrated Claude into their products. The first customers of the latest GPT-4 released by OpenAI also include Duolingo, a language learning application, Morgan Stanley, etc. The Icelandic government is also using GPT-4 to protect its language.

  Competition is becoming increasingly fierce.

  As AI’s capabilities become stronger and wider, the transparency of many companies becomes lower and lower.

  The most obvious thing is OpenAI’s technical report on GPT-4, which writes: "In view of the fierce competition environment faced by large-scale models such as GPT-4 and security considerations, the report does not contain further details on architecture (including model size), hardware, data set construction, training methods, etc."

  Still, some companies have released more details. For example, Meta publicly released LLaMA, and put forward licensing requirements for commercial use. Together has launched OpenChatKit 0.15, a chat robot. Developers can fully access its source code and the data set used to train the robot. ChatGLM-6B in Tsinghua University is also open source.

  A large influx of funds

  AI technology and chat bots have attracted a lot of money, the most notable of which is that Microsoft has thrown $10 billion for OpenAI.

  According to a report by Forbes magazine on the 15th, American startup Adept AI Labs has raised $350 million in Series B financing, with a post-investment valuation of at least $1 billion. In February this year, Google invested $300 million in Anthropics. In addition, Character AI raised $200 million from Anderson Holovitz Venture Capital this month; Perplexity AI, established in 2022, completed a financing of US$ 25 million led by Enyi Investment Company. After financing, the company’s valuation will reach US$ 150 million.

  Salesforce Venture Capital also launched a $250 million fund and invested in a series of AI startups including Anthropi, Cohere and You.com.

  Multi-country development blueprint

  These AI models have become "frequent visitors" of many media and attracted the attention of decision makers all over the world.

  In October 2022, the White House released the blueprint of the bill of rights for artificial intelligence. Recently, Alexander Madrid, a professor at the Massachusetts Institute of Technology, proposed to the Committee on Cyber Security, Information Technology and Government Innovation of the US House of Representatives: "Artificial intelligence is no longer a science fiction novel, nor is it a technology limited to the laboratory. Artificial intelligence is a technology that has been widely deployed and adopted, and it will completely change our lives; We now need to think about how to shape the world driven by artificial intelligence. "

  In the past week, Britain announced plans to set up a basic model task force reporting directly to the Prime Minister. At the same time, the British government also announced that it will invest 900 million pounds to build a billion-dollar second-class cutting-edge supercomputer, and will also develop its own chat robot "BritGPT". As British Prime Minister Sunak said: "Basic models like ChatGPT are beginning to show extraordinary new capabilities … … This is the new reality we are facing! The competition to create, develop and utilize these new technologies has flourished around the world. "
