Do you remember the Olympics we chased together in those years? Every opening ceremony, in addition to the wonderful performances, the most anticipated is the lighting ceremony of the cauldron stand, the flame collected from Olympia in ancient Greece, across thousands of mountains and rivers, and finally shined on the blazing cauldron stand, symbolizing the Olympic spirit of peace, friendship and progress, and also igniting the enthusiasm of the world
The design of the cauldron of the previous Olympic Games has always left a deep impression on us: at the 1992 Barcelona Olympic Games, the image of para athletes shooting the torch with bows and arrows is still moving; In the 2008 Beijing Olympic Games, the slowly unfolding "picture scroll" slowly rose, and the scene of finally "lighting" the Olympic cauldron was even more amazing to the world......
This year, in the romantic capital of Paris, the Olympic flame was lit again, and this time, the France played a new trick! They actually built a torch stand with "no flame", can you believe it?
Don't be surprised, this is not a "magic", but the perfect combination of technology and environmental protection, Paris Olympic Organizing Committee President Tony ·Estanguet said, they want to hold the "greenest" Olympic Games, so in terms of energy use, resolutely give up the traditional fossil energy, choose more environmentally friendly electricity, so, we see this with light and water mist "become" out of the "electric flame"
Don't underestimate this "electric flame", it is full of scientific and technological content behind it! This cauldron with a diameter of 7 meters has 40 LED spotlights inside, which can emit 4 million lumens of light, which is blinding! In addition, there are 200 high-pressure nozzles, which control the spray of water mist, combined with a powerful optical flow, to form the "flame" we see vividly
It is said that in order to make the "ignition" ceremony foolproof, on the night of the opening ceremony, when the two legendary France sports champions "lit" the cauldron, the staff behind the scenes played twelve points of spirit, accurately turned on the LED lights and water mist nozzles at the same time, so that the magical effect of the instant transformation of the "flame" is really hard behind the scenes heroes!
With such a cool "electric flame", the power supply must also keep up, in this regard, the France Electricity Group (EDF) has shown its ability to take care of the house, they specially customized cables, the power and high-voltage water flow are continuously transmitted to the cauldron to ensure that the "flame" continues to "burn"
What's more, this cauldron can still "go to the sky"! During the day, it will be controlled by a cable and stay close to the ground, so that everyone can see it up close; At night, it will "rub" a huge tethered balloon and slowly rise to a height of 60 meters, blooming a dreamlike light in the night sky, perfectly echoing the romantic atmosphere at the opening ceremony
In other words, the modern hot air balloon was first invented by the France, as early as the 18th century, it was successfully lifted off in the Tuileries Garden in Paris! Therefore, the use of balloons to raise the cauldron at the Paris Olympics is not only for visual stunning, but also a tribute to France's long history of balloon flight
