What is the design area of Beijing Olympic torch? Which plan are they?

After watching the lights of Doha Asian Games, I suddenly want to design for the 2008 Olympic Games. I searched online, and it seems that many people have thought of the scheme of using beacon towers. I'm not going to write it; But on second thought, at least it took me a little brain, and my capacity is limited, so I'd better write it out. Because the Great Wall is the symbol of China, the ignition scheme also draws lessons from the design of beacon tower, and the most important thing is to draw lessons from the idea of beacon tower transmission. Judging from the geographical distribution of beacon towers, there are four design schemes: 1, which is located on the bird's nest and forms a circular Great Wall. Because the distance is not long, we can consider building it completely in the shape of the Great Wall. 2. Establish beacon networks in all competition venues in Beijing. 3. All the Olympic venues in China form a lighthouse network. 4. Establish a nationwide beacon network in major cities across the country. The latter three schemes, the center of the beacon network, are all in the Bird's Nest. Because the distance is too far, it is impossible to connect the beacon tower with the Great Wall. Then, design the ignition scheme. Because it is a beacon network, unlike other ignition schemes, it can be done at one go. The lighting of this bonfire network should start from a certain point and then be transmitted to the main torch of the Bird's Nest through some kind of transmission route. So, the design here is mainly about how to let the bonfire pass. The transmission scheme should not be too simple, and some difficulties are better, but it can be realized as long as it is well controlled. Because it is a network, the fire transmission is not linear, but gradually moves closer to the main torch in the form of a network. I initially thought of several schemes: 1, archery scheme, which can only be used in the first beacon scheme. Moreover, this scheme seems to have been used in an ignition scheme, and there is nothing new. 2. Use the athlete relay, light a small torch from one beacon tower, and then send it to the next beacon tower like the torch relay. 3. Use concave mirror to collect the optical fiber to the next beacon tower and ignite it with heat. This has certain requirements for the manufacturing and installation accuracy of concave mirror, and it is difficult to implement. Finally, the design of ignition process is considered. There are two simple ones: 1, which can complete the beacon transmission process in a very short time. 2. Light it from the beginning of the opening ceremony, then pass it slowly, and finally light the main torch at the end of the opening ceremony.
