is it better than Pfizer, considering 1.5 -2 yrs later ?
Considering you're talking about previous vaccines that successfully contained deaths to 10k people vs vaccines that haven't helped to stop casualties of several million people, a more interesting question would be if this vaccine can be better than rival Chinese vaccines?

Unless there has been a tech breakthrough, probably not. The issue with most mRNA vaccines is that they're barely able to build antibodies in the mucosa. The benefits is that it is relatively easy(fast) to develop booster shots that can cover new mutations. Some protection is better than no protection at all. Apparently, the Indonesia tested efficiency against omicron is 71%, which means 1 shot is equivalent to 3-4 shots of old-type mRNA vaccines.

For now it is not approved in China itself yet, and neither are the other types of mRNA vaccines. The Chinese public regulators will not accept vaccines that need 4-5 shots in order to even have moderate effectiveness against omicron. If this vaccine isn't much better, it may not be approved.

At 17:00 on September 30, the world's first 100-megawatt advanced compressed air energy storage national demonstration project was successfully connected to the grid for power generation in Zhangjiakou, Hebei.
The total scale of the project is 100 MW/400 MWh, and the core equipment autonomy rate is 100%. It can generate more than 132 million kWh of electricity every year. It can provide power protection for about 50,000 users during peak power consumption, and can save standard coal every year. 42,000 tons, reducing carbon dioxide emissions by 109,000 tons. It is a new type of compressed air energy storage power station with the largest single-machine scale and the highest efficiency in the world.
The technology of the demonstration project is provided by the Institute of Engineering Thermophysics, Chinese Academy of Sciences (hereinafter referred to as the Institute of Engineering Thermophysics), the investor is Giant Group Zhangbei Giant Energy Co., Ltd., and the equipment provider is China Reserve National Energy (Beijing) Technology Co., Ltd. The project will start construction in October 2020, complete equipment installation and system integration in December 2021, and start live commissioning.
Xu Yujie, a researcher at the Institute of Engineering Thermophysics and director of the Energy Storage R&D Center, told the China Science Journal that energy storage technology is the key supporting technology to achieve the goal of "carbon peaking and carbon neutrality". Advanced compressed air energy storage technology has large scale and high cost. It is a long-term and large-scale energy storage technology with great development potential, which can realize peak regulation, frequency regulation, and regulation of power system. Phase, spinning reserve, black start, etc., have broad development space and strong competitiveness in improving power system efficiency, safety and economy.
The reporter learned that traditional compressed air energy storage mainly uses low-valley and low-quality electricity to compress and store air in large gas storage caves; during peak electricity consumption, high-pressure air is released from the gas storage caves, and the same fuel is burned to drive turbines to generate electricity. , has been commercially used in Germany and the United States. However, there are three main technical bottlenecks in traditional compressed air energy storage: first, relying on fossil fuels to provide heat sources; second, relying on natural gas storage caves, such as rock caves, salt caves, abandoned mines, etc.; third, the system is inefficient and needs to be further improve.
In recent years, in response to the bottleneck of traditional compressed air energy storage technology, countries have actively developed new compressed air energy storage technologies, including regenerative compressed air energy storage systems, isothermal compressed air energy storage systems, and liquefied air energy storage systems. The Institute of Engineering Thermophysics has been focusing on the research and development of compressed air energy storage technology since 2004. In 2009, it originally proposed a new principle of advanced compressed air energy storage technology. Since 2013, from 1.5 MW, 10 MW to 100 MW, basic theories such as system process coupling and dynamic optimization have been developed, and key technologies such as multi-stage compressors and expanders, and high-efficiency and compact heat storage heat exchangers have been broken through. As well as system integration and control technology, an engineering demonstration has been completed.
Xu Yujie introduced that after the completion of Zhangjiakou International's first 100-megawatt advanced compressed air energy storage national demonstration project, a new model of large-scale energy storage system operation and a strategic emerging industry cluster will be formed, which will effectively promote the scale and industrialization of my country's compressed air energy storage technology. The development process of commercialization is of milestone significance for promoting the energy revolution and building a new power system.
The above-mentioned related work has been supported by the Chinese Academy of Sciences’ Class A pilot project “Key Technologies and Demonstration of Transformative Clean Energy”, the National Development and Reform Commission National Renewable Energy Demonstration Zone Major Project, and the National Science Fund for Distinguished Young Scholars.

Anton is Pan's mentor.

Pan took part in Anton's research work as one of the main contributors. Of the four papers on quantum communication experiments cited for Anton's award, Pan was the primary author of two, and one of the secondary authors of the other two.

Hope this award can address the skeptism by some forum members towards the science of quantum information in general and Prof. Pan Jianwei himself in particular.

谈到自己的导师安东·塞林格,潘建伟的第一印象是他非常知人善任。

“刚到导师团队的时候,我没有做实验的经历。面对这种情况,一般的导师都会比较犹豫,不会让一个搞理论的人去做实验。但是,因为我导师自己也有做理论的背景,所以他也很高兴,同意我去做实验工作。”潘建伟说。

同时,安东·塞林格也能够尊重学生的选择,并加以适当的引导,让学生实现自己的梦想。“从这个角度讲,他又是一位非常好的老师。”

“塞林格老师很有远见,他成功预见到一个新领域即将诞生。”潘建伟记得很清楚,欧洲第一个关于量子信息的欧盟联合课题,就是在塞林格的主导下设立的,“我看到他的项目申请书是1996年”。

作为安东·塞林格的学生,颁奖委员会提到的安东·塞林格的研究工作,潘建伟院士是最主要的参与者之一。

“颁奖委员会提到了我导师安东·塞林格的四篇量子通信实验文章。我是其中两篇文章的第一作者,两篇文章的第二作者。”潘建伟说。

同时,“颁奖委员会还提了另外三篇文章,而这三篇文章都是中国科学家独立开展的研究工作。所以,从这一点讲,我不仅是加入了塞林格的研究团队,也参与了开创量子信息物理学这个领域,我感到很幸运。”潘建伟说。
