I am often asked what is the scientific method that I refer to when I talk of China’s great advantage over other nations. It is a mix of the Marxist approach and Chinese traditional ways.
This article reveals an astounding long term approach to high speed transmission of electricity. Sent to me by Keith Bennett, it shows how China looks for 100 year plus solutions to challenges. They spend a long time analysing the problem and then research how different nations are addressing this. They then add their own and other nations academic research and begin to flesh out ideas.
The most supported ideas are then subject to various tests. Then the whole process is probably updated as several years will have passed. The preferred options are updated and a couple or three are then put to more stringent tests.
Eventually one or two ways of approaching the problem will be put into operation for up to five years to see what it shows.
Then policy is recommended through the structure of the Party and the Government.
And the result for example is high speed rail or….
China’s giant ultra-high voltage grid is ambitious as its high speed rail

Ultra-high voltage energy grids are needed for efficient power transmission across large distances.
A 100 mile (160 km) power line at 765 kilovolt carrying 1000 MW of power can have losses of 1.1% to 0.5%. A 345-kilovolt line carrying the same load across the same distance has losses of 4.2%. China’s 1.1 megavolt line can have power losses that 10 to 20 times less than 345 kilovolt lines.
1.1 megavolt transformer
ABB helped create the 1.1 megavolt transformers and key equipment for world’s first 1,100 kilovolt (kV) project in China.
When fully operational the UHVDC link will be capable of transporting 12,000 megawatts of electricity over a distance of 3,000 km from the Xinjiang region in the Northwest, to Anhui province in eastern China. This vast amount of electricity is equivalent to twice the average annual power consumption of Switzerland.
