Due to large changes in population, as well as people being told to move into cities, what changes in technology must China make to meet the needs of the future?
There are some important things that China must to change. For example, with the increasing of constructions in big cities, the demand of electricity increases significantly, so the cable network needs to be improved by changing the old system to the newest electric system. Because when the cables transfer the electricity, lots of electricity will lost because of long distance. And another thing that China needs to change is public traffic system, because nowadays, the traffic jams and the pollution which is produced by cars are very serious in China.
What are some innovative technologies being made in China today?
In China, space technology and high-speed rail are two innovative technologies being made in China. For example, since China sent the first Chinese astronaut to the space in 2008, china start to build its own space station to compete with Russia and USA. Besides, while the Chinese space station is built, the largest mapping telescope in the world is built in Guizhou Province.
As for the high-speed rail, China’s high-speed rail is the fastest railway in the world. Its speed reaches 290km per hour, and the length of railroad that China built is more than 29000 km.
3）Why is renewable energy so crucial of the future of China?
Because China wants to let renewable energy replace the fossil fuel. The pollution that fossil fuel makes a negative effect to half of 1.4billion Chinese. Besides, renewable energy resource, like solar and wind, can produce more electricity than the fossil fuel.
4）Where is renewable energy being built? What types?
Solar energy plant----Qinghai
Wind farm ----Xinjiang
5）What are some difficulties in designing and building renewable energy?
When the engineers design the windmill, he/her should design a strong instruction that can resist the rainstorm and would not be broken down. As for building it, the main difficulty is workers need to assemble the windmill at a place which is 70m high, and blades are long and heavy, so workers must make sure blades will not fall during the assembling
