Beijing 2022 venues to harness technology for carbon neutral Games******

BEIJING, Nov. 20 (Xinhua) -- The Beijing 2022 Olympic and Paralympic Winter Games, will harness technology to deliver a carbon neutral Games to people across the world next year.。

Yu Hong, head of technical department of the Beijing Organising Committee for the 2022 Olympic and Paralympic Winter Games (BOCOG), said at a press conference on Thursday that "we have plans, effects, and also expectations on holding a green Olympic Games with high-tech tools."

The National Speed Skating Oval, known as the "Ice Ribbon", applies carbon dioxide trans-critical direct ice-making technology, bringing carbon emissions close to zero. The waste heat in refrigeration can be further recycled, enhancing the energy efficiency by 30 to 40 percent.。

The Water Cube, a dual Olympic venue where the curling will be held during Beijing 2022, was turned into an Ice Cube within 20 days by using a quick-disassembly and dynamic-levelling monitor system. The Bird's Nest Stadium has also evolved into a digital and low-carbon venue with the help of the Internet of Things and artificial intelligence.。

"Wind and solar energy from surrounding areas will be transferred to the three competition zones of Beijing 2022, providing a sufficient clean energy supply for all venues during the Games, with the goal of holding a carbon neutral Games with sustainability," Yu added.。

For the snowmaking in Yanqing and Zhangjiakou competition zones where snow sports games of Beijing 2022 will be held, Zhao Weidong, a director of the BOCOG, said that the artificial snowmaking has no impact on the local water security and ecology and will not cause water shortages.。

Zhao added that the organizers have applied the world-leading water-conserving equipment for artificial snowmaking. The water demand during the Games will account for 1.6 percent of the total current water consumption in Yanqing district, the Beijing Water Authority said.。

The BOCOG said that 5G signals can cover all Games venues and roads connecting them, including the Beijing-Zhangjiakou high-speed railway, enabling the world audience to enjoy the Games through 8K broadcasts in ultra high definition and to experience the Games in virtual reality.。

"We sincerely wish all athletes to achieve good results in the high-tech venues during the Games and will also endeavor to apply these technologies into developing better game areas and equipment for sports enthusiasts in the future," Yu concluded. Enditem。

西安地铁3号线桃花潭站A口扶手电梯拆卸约两月 老人爬63个阶梯有点累******

近日,西安市群众易先生向华商报24钟头新闻热线029-88880000体现,他住在达州路北部,常常要去地铁3号线桃花潭站转乘地铁站,“达州路路北是A口,A口以前有电动扶梯,但大概2个月前,扶手电梯给拆了,只有爬台阶,确实很不方便。”。

易先生说:“这一站地铁口是地上铁,如今每一次爬台阶非常累,老人爬得话,十分费劲,不清楚何时能修复电梯轿厢。”。

11月4日,华商报记者赶到地铁3号线桃花潭站A口,见到A口仅有一个直爬梯,紧连的北端是一个空闲地,放置着货车,工程车辆等。有老人沿着台阶往上走,随后去搭乘地铁站。直爬梯分成4段,记者数了一下,一共有63个台阶。

记者开车赶到大马路正对面的B口,B边有电动扶梯,但从A口抵达B口并不方便,A口间距过街天桥约有200米间距。

华商报记者以公民真实身份了解了地铁3号线桃花潭站客服人员,另一方说,她们一直在给上级领导体现,现阶段收到的信息是,北部这方面土地资源要完成更新改造,更新改造后修复扶手电梯,但何时能修复不清楚。

华商报记者以公民务必连接到西安地铁服务电话,以后,西安城市轨道实业有限责任公司工作员回应,因A口北端空闲地要开展农田更新改造,因此对扶手电梯开展了过渡拆卸,临时让大伙儿走台阶,给大伙儿造成不变期待获得了解,更新改造进行之后在原地不动修复电动扶梯,现阶段A口北端空闲地是一个临时性地下停车场。针对土地资源更新改造周期时间,涉及到好几个单位,会尽早融洽提高效益。
