1. Olympic torch
The torch of this Winter Olympics adopts the technology of liquid rocket engines in aerospace, which can well avoid the problem of torch extinguishing.
Although hydrogen is environmentally friendly, to maintain the same combustion time, hydrogen requires twice as much storage space as propane, which will increase the volume of the torch.
In order to maintain the volume of the torch, the torch team decided to use a high-pressure method to store hydrogen, without increasing the volume of the torch, by increasing the pressure, reducing the volume of hydrogen storage.
High-pressure hydrogen storage technology can also enable the stable release of hydrogen, so that the flame can be stably burned.
In order to avoid wind, rain, etc. leading to the torch extinguishing, the team also adopted a blunt body stabilization technology to protect the root of the flame in the surface, so that even if the flame is extinguished above, the root is not affected.
Second, the ice cube: to achieve the free conversion of water into ice and ice to water
In line with the concept of sustainable use, the "Water Cube" was transformed into the "Ice Cube". Through the innovative application of technologies such as convertible venues, detachable ice systems, convertible environments and smart venues, scientists have realized the "Water Cube" and "Ice Cube" that can freely convert summer and winter scenes, and the "Ice Cube" has thus become the first "double Olympic" venue in history that can be operated for both water and ice projects.
In order to create high-tech green venues, the 6 venues used in the Beijing Winter Olympics have formed a set of black technology with independent intellectual property rights, and 19 venues are using renewable energy sources such as wind power, solar energy and photovoltaic power generation. Many buildings are remodeled on top of the original building, but it is not simply "magic", but new functions are added to the original use function. The capital's stadium will undergo thirty venue conversions, such as the National Aquatics Center "Water Cube", which is the first venue to achieve ice water conversion, realizing the sustainable use of the water cube to the ice cube. In addition, the curling track's stadium will also be set up on the pool.
Third, laser engraving
The laser engraving used in this Winter Olympics is the top of the technology. Because what is presented at the Winter Olympics is not a flat sculpture, but a three-dimensional screen, drawing a pattern with light.
Not only the pattern is drawn, the pattern also has dynamic vitality, the Yellow River water rushes and surges, the snowflakes condense and form, the ice blue beats like a flame above the ground, and the ice circle five rings are born in the ice and snow, just like seeing nature freeze in real time, indescribably wonderful.
Fourth, intelligent epidemic prevention restaurant
Considering the epidemic situation, in order to reduce the contact of personnel in the restaurants of the Winter Olympic Games, the restaurant stir-frying and delivery of food are completed by robots, and foreign reporters cannot eat and click to take pictures. A few days ago, the British media reported a video in our Winter Olympic restaurant, and the fully automatic cooking equipment and intelligent ordering system clearly visible in the picture opened the eyes of foreign journalists and could not stop marveling. After the report came out, it quickly caused a sensation abroad, and everyone lamented that China's intelligent robots were so powerful. I am even more interested in this intelligent system in the Restaurant of the Winter Olympics. At that time, the foreign reporters who came to the Winter Olympic restaurant only cared about taking pictures the whole time, the meal was not eaten, the robot had attracted all their attention, and they could not remember that they had come to eat.
