The Winter Olympics being held in Beijing are full of excitement, from the opening ceremony to a pair of sneakers, all of which are integrated into the power of science and technology. Among them, there are many Zhejiang enterprises to help.
At the opening ceremony of the Winter Olympics, the ignition ceremony was impressive, how to make the light shine accurately and evenly on the main torch platform and the snowflakes representing the countries? Led lighting equipment independently developed by a company in Hangzhou has completed this challenge.
Wang Zhongquan, chairman of Hangzhou Luolaidian Technology Co., Ltd
We have a very good precise light control, so we can concentrate the light very well, all in the position of the torch.
In the past few days, in the Yanqing area of the Winter Olympic Games, more than 200 hydrogen fuel buses providing connection services are busy. Compared with conventional energy vehicles, hydrogen-fueled buses can reduce carbon dioxide emissions by about 57 kilograms for every 100 kilometers traveled. A research institute in Ningbo participated in the research and development of this bus.

The advantages are mainly zero emissions, the second is energy saving and environmental protection, the third is that the battery life is relatively long, and there is a low temperature environment, its running performance is better.
Over the past two years, the team has overcome technical problems such as short life of hydrogen fuel cells and difficult low temperature cold start, and at the end of last year, it achieved a low temperature start test at minus 30 °C.
Chen Ping, chairman of the Ningbo Hydrogen Energy Research Institute of state power investment
In a cryogenic cabin, continuous testing has enabled our products to perform low air cooling start-ups without any obstacles.
This Winter Olympics, a sports shoe that will be hot has aroused heated discussion. The temperature inside the shoe can be adjusted from 38 °C to 42 °C, and even in the snow of -25 °C, the heat heat can be kept warm for up to 5 hours. Providing electronic devices for heat-generating insulated shoes is a company in Haining, Jiaxing.
He Lei, founder of Haining Jizhan Technology
Traditional electrons (devices) don't have stretchability, we can do something so flexible, and can stretch.
The flexible battery developed by the company is wrapped around the upper of the shoe, and the elastic heating blade in the shoe is connected, and the elastic heating plate can continue to heat up at the push of a button.
