This is an unprecedented gathering and an unprecedented celebration. There has never been such a celebration in Datang. Maybe it will become the norm in the future, but this year is definitely the most special year.
This is the first time, but it definitely won't be the last.
For that day, Li Ke even did not hesitate to demonstrate the role of electricity for the first time, mainly by erecting large speakers on the relevant squares. Electricity is actually not a difficult thing for Li Ke now. After the steam engine is invented, the main source of energy for mankind for many years to come will become boiling water.
Until Li Ke traveled through time in his previous life, the form of energy used by humans to boil water still dominated. There are only two ways of change that can be seen in the future, at least when Li Ke traveled through time.
One is a form that can be used in controllable nuclear fusion to directly cut magnetic field lines to generate electricity. It may become a mainstream power generation device in controlled nuclear fusion in the future. Of course, Li Ke did not see it.
Another kind of Li Ke has been produced, but it has not been used on a large scale.
That is the technology of fourth-generation thorium-based molten salt nuclear reactors combined with supercritical carbon dioxide to generate electricity, replacing water vapor with supercritical carbon dioxide.
However, in the Tang Dynasty, it is estimated that these technologies will not be popularized in Li Ke's lifetime, and boiling water will be the mainstream way of obtaining energy for humans for a long time to come.
Although the electric power Li Ke has not yet been launched in Datang, it is actually not difficult to make a generator. It is estimated that it will take more than half a year at most, and the first generator may be used in Chang'an City by then. , it is estimated that Datang Evernight City will be the first place to adopt it.
Generators driven by large steam engines are sufficient for the current Tang Dynasty, and they are not difficult to make. What Li Ke lacks is just the popularization of basic subjects.
To be honest, the current weapons and equipment of the Tang Dynasty can actually be further innovated, but Li Ke is not in a hurry.
There are several reasons, the first is that it is not necessary.
The large-scale armed all-steel armor combined with the large-scale military crossbows that have been equipped to the squad, as well as the bows and arrows that have been widely popularized on a large scale, combined with the three-edged armor-piercing arrows, can crush the main enemies that Datang currently faces.
In fact, there is no difference from crushing with a rifle.
On the contrary, rifles are not even as good as bows and arrows. The current bullet production of rifles cannot keep up. The main problem is gunpowder. Although basic industries are available, there is still a long way to go before basic industries are fully popularized on a large scale. At least It takes more than five years to train the first batch of technicians.
At present, Li Ke has begun to build a large number of technical schools near all major cities in Datang, and then began to train the first batch of workers in technical schools.
If primary schools, middle schools, and universities cultivate the future of Datang, then technical schools cultivate the present of Datang.
Just like there was a period in the previous life when entering a technical secondary school was more satisfying than going to university. During this period, technical schools were obviously more popular than universities.
However, Li Ke is not prepared to make much change in these aspects. Society promotes progress in a regular manner. Although Li Ke can change, such changes that do not affect the overall situation are not necessary.
In fact, the top group of people actually have enough vision to make their own choices. The cultivation of scientists in Datang will naturally not reduce the relevant efforts.
Therefore, in a short period of time, there is actually no need for any rifles or cannons, or in other words, the suppressive power is not as good as the bows and crossbows.
Because the crossbow lacks arrows, when there is a shortage of crossbow arrows, you can use local materials and even capture the enemy, but bullets cannot.
The processing of gunpowder is not that simple. Gunpowder that cannot keep up may cause wrong effects, so rifle and cannon Li Ke is not in a hurry at all.
Let's put it this way, normal historical development should be like World War I and World War II, when a war broke out, and then some technological reserves were transformed into brand-new weapons, and then quickly put into use.
But what Li Ke did was to first bring the basic industry to the point of forming a primary industrial country, and then in turn carry out weapons and equipment reform.
The speed of exploding equipment is much faster than now, because even if Li Ke comes up with muskets and cannons, the Tang Dynasty will not occupy the country very fast.
It is easy to occupy, but difficult to rule. If some territories are not fully prepared for rule, there will be no benefit in occupying them. Instead, it is better to leave them to the enemy first.
What Li Ke is doing now is to first start to reform Datang, and secondly to supplement and strengthen the shortcomings of Datang after the reform.
When Datang grows into a true giant, it will be time to spread her influence.
Before that, Li Ke wanted to set a goal and an example for Datang!
This gathering was a very important signal, so Li Ke also used electricity that he had not used until now, and installed speakers around the entire square.
Of course, the speakers created by Li Ke are incomparable and impossible to compare with the speakers of later generations. In fact, they are probably equivalent to the large speakers in every village in the past. These speakers are just enhanced through some technologies. Some equipment in the warehouse was used to make their sound transmission as consistent as possible.
Don't pursue sound quality or anything like that. There's no way to pursue it. These speakers were all cast in Datang.
Of course, Li Ke was definitely not doing this work to show that what he had learned in college in his previous life was finally put to use.
As for power supply, Li Ke used two generators. There is a backup generator in the strategic warehouse, but it is definitely not a small backup generator. In fact, there are two lines here, one line is connected to ordinary civilian electricity, Go to the National Grid.
Another power supply line is a special combat readiness line, which is powered by a separate power station. This means that even if the entire city's civil power grid is powered off, this power grid will not be powered off.
In addition, important large electronic equipment in the warehouse is equipped with UPS, but that thing is completely different from the small UPS in the office building.
So in short, after expanding to the present, Li Ke found two 5-kilowatt gasoline generators in the entire warehouse. They were in the logistics warehouse. Li Ke didn't know what they were used for. As for gasoline, Li Ke pulled it out from the vehicle in the parking lot.
The civilian strategic warehouse in his mind did not have fuel reserves, that was a matter for military warehouses. But fuel has many uses, so their warehouse has an internal gas station.
However, the internal gas station is located in an independent and safest peripheral area in the entire warehouse area. Unfortunately, it is in two different directions from the office building, so it is not unlocked yet.
