Tang Ning had to do two things within a month of staying in Xurong Village. The first thing was to teach Xurong Village to install and use a high-power wireless telegraph system, including the installation of antennas. In order to keep it confidential, Tang Ning suggested that Xurong Village not build a tower, but quietly build it on the mountain. The second thing was to invent a system of wind power generation so that the telegraph system brought back to China by Xurong Village does not require battery supply. This is a relatively new thing for the Far East.

Tangning uses the most inconspicuous Q-shaped type in vertical axis windmills. Its structure is very simple, like a Q, with only a thin circle. If it does not rotate, you will not know that it can rotate. This design can play a certain confidential role, and is easy to make, portable, easy to install, and easy to repair. One key component is to convert the alternating current generated by the windmill into a rectifier. If you look carefully before, you will remember that the biggest characteristic of a vacuum tube is that it can play a rectifier through only one current.

Tang Ning wanted to teach Lao Xu basic electrical knowledge. In the end, it took Lao Xu two months to learn this complete set of inter-era spy equipment. With this good thing, Tang Ning would cross the ocean to understand what was happening in China in advance, especially the war between the Qing army and the Taiping army.

After preparing a lot of spare replacement parts for the telegram, Tang Ning sent Lao Xu to the road. In fact, Lao Xu was not old, he was only 30 years old.

In the process of developing wind power, Tangning felt that wind power generation is a good thing. Why not focus on developing this power generation technology? Because it is very clean, unlike thermal power generation. No matter how it is controlled, there is always a small amount of sulfur dioxide and dust escape. Once it is used on a large scale around the world, air pollution is always a problem.

According to the normal order of human electricity development, coal-burning thermal power generation must be developed first, because steam engines have been invented, and using steam engines to rotate coils to generate electricity is a very intuitive solution. Moreover, wind power generation has a big problem, which requires the use of lightweight and hard materials. In this era when iron is used, it is difficult for people to imagine that efficient windmills can be produced. There is no high-tech material such as carbon fiber, but I have acetate fiber! This material is made of a strong tool handle and the windmill blades will be effective.

Wind power generation is less intuitive than hydropower, because the size and direction of wind are changing at any time. In the early era of electrical energy without rectifiers, no scientist will regard wind power generation as the main power generation solution. Although wind power is everywhere, it has fewer restrictions than hydropower generation. If multiple wind power generations are to be connected to the grid, they have to invent "inverters" to turn DC power into AC power again, which is another painful limitation. Tangning thinks that by using the battery as a central control switch, the DC power switch can reversely become AC power.

The many restrictions on wind power make its cost higher than thermal power generation, but this is not the biggest cost. In fact, the first-mover advantage of thermal power generation is the biggest cost advantage. The initial form of an industry will give that form a cost advantage, such as the QWERT keyboard. The advantage of human learning cost actually makes this unscientific keyboard layout transcend the limitations of time and space through Tangning, and continues to dominate typewriters and future computers.

Tangning did not intend to develop technology step by step. How good is wind power generation? Maybe it will gain a cost advantage due to its first-mover advantage. It will establish its dominance when the world's first power plant was born, at least the dominant advantage of urban electricity and residential electricity. Once Tangning's power grid is established, hum, thermal power generation, I will not let you join the network at all, see how you compete with me!
