Chapter 890： copper
After Wu Changqing consumed this wave, he took a look at the system data.
Host: Wu Changqing.
The current territorial area is 12.4 million square kilometers, the total resource points are 372 million, and the remaining 328.5 million.
The current area has a population of 220.4 million, a total of 220.4 million technology points, and the remaining 156.32 million.
It seems that there are still a lot of resource points and technology points, but the more you get to the back, the less you spend.
Like this time just for the needs of the steel industry, he spent 20 million resource points and 5 million technology points.
This kind of consumption will disappear after ten or twenty times.
The system also prompts that it will be updated in the future. According to Wu Changqing's experience in playing games, the update is to stimulate the consumption of players, and it will definitely bring out some new and expensive things.
Therefore, Wu Changqing couldn't use up all these resource points and technology points, and had to leave some as a precaution.
In case there are materials that can achieve superconductivity at room temperature after the update, or nuclear fusion materials and technologies that can be controlled, or there is a magic drug that can keep men in their seventies, there is no resource to buy Don't you want to cry to death?
No matter how good Dahua develops, it is not as good as not to fail, or because his personal longevity is important, he is not a true saint.
The land area on the earth is limited, and Wu Changqing is not sure whether he will go to the moon to plant a flag and declare that the moon is the territory of Dahua whether the system will recognize it.
Until now, the entire world is under Wu Changqing's control.
The only thing that cannot be controlled and is still full of mystery is this broken system.
Faced with this unknown gadget, Wu Changqing was very cautious, did not overuse it, and did not completely rely on it.
He didn't know whether it was right or not, and he didn't know until he got it.
The emergence of stainless steel is an evolution of the steel industry.
It used to solve the problem from scratch, but now it solves the problem from existence to good.
With all kinds of stainless steel, the performance of the machine can be greatly improved.
At the same time, some machines that could not be made before can also be made now.
For example, the high-speed engine, the engine made of ordinary steel in the past, can't be too fast, and the parts will be damaged quickly if it is too fast.
Machines that cannot be transported continuously have no practical value even if they are built.
With the use of special stainless steel, the service life of the components can be greatly improved, and the engine can be turned faster.
The improvement of engine performance has a huge boost to the entire industry.
This is still a prerequisite for building an airplane, and the speed is not fast enough to get to the sky at all.
Today, as long as the engine continues to be improved, it is theoretically possible to manufacture aircraft.
Both hot air balloons and hydrogen balloons have great shortcomings, that is, they are used for miraculous effects in the military, but they are not very useful at other times.
With Wu Changqing's reminder, some people are already studying the issue of flying into the sky.
With special steel, projects that could not be done before can now be put on the agenda, such as the Nanjing Yangtze River Bridge.
This is an important project for connecting the North-South Railway, and it has been mentioned many times.
It's just that people from the Ministry of Science and Technology said that the current strength and toughness of steel are simply not enough. Either the bridge piers are built very low and densely built so that they are very close together, otherwise the steel will collapse due to insufficient strength and toughness.
The bridge piers are built too low, and the spacing is too small, which will affect the passage of ships, which is not cost-effective.
Therefore, this project has been dragged down.
But now, as long as high-strength low-alloy steel is used, the span of the bridge can be increased and ships under 5,000 tons can pass through.
Although there are still many difficulties, in theory, they have the ability to build a bridge across the Yangtze River in Nanjing.
Connecting the north-south railways and highways will greatly save the cost of north-south transportation.
The current north-south transportation is obstructed by the Yangtze River, and it has to be transferred several times in the middle, which is very troublesome.
After the coal from the north is transported to the north bank of Nanjing by train, it must be transported to the south bank by ship.
One loading and one unloading is time-consuming and labor-intensive.
This is not the only situation in Nanjing. Wuhan, Zhenjiang, Wuhu, and all cities on the edge of the Yangtze River have the need to build bridges across the river.
This is also true of other places with large rivers.
Dahua’s infrastructure project has just begun.
Steel is the most used metal by Dahua, followed by copper and aluminum.
Silver is the best conductive metal, but silver is a high-value currency. Dahua still has no way of luxury to use silver to make wires.
If you really do this, there will be countless people going to cut the wires and sell them at night.
Those wires running in the wilderness must not be spared.
When the income is high to a certain extent, it is difficult for the law to maintain its deterrent effect.
Therefore, Dahua's current cables are all copper, and the crime of stealing wires is very serious. Started at least ten years, causing heavy losses and direct death penalty.
Only in this way can the thieves give up the idea of stealing.
In addition to making cables, copper is also widely used in other areas. After the flintlock rifle was eliminated, Dahua now makes bullets and some shells are all made of copper.
Door valves, molds, sliding bearings and other machine parts also need copper.
In fact, there is a shortage of copper in the Central Plains. Nowadays, the use of copper is wider and wider, and the demand is increasing, and there is a situation in which demand exceeds supply.
To this end, Wu Changqing also issued a government decree that no more copper coins will be collected when taxes are collected, only silver coins and paper money will be collected.
This is done so that paper money can completely replace copper money so that the copper can be used in industry and other areas.
It is too wasteful to be used as currency for circulation, and it is unnecessary.
Moreover, it is inconvenient. Nowadays, prices have risen so drastically that a penny has become worthless.
It's a bit tired to buy things with all copper coins.
In order to avoid causing too much turmoil, Wu Changqing did not prohibit the circulation of copper coins, nor did he force the people to convert copper coins into banknotes.
In that case, it is easy to cause panic and hoarding.
Moreover, paper money has not yet become popular in remote areas, and the main currency is still copper.
I want paper money to completely replace copper coins at one time. The steps are too big and it is easy to pull eggs.
Anyway, Dahua is not particularly short of copper in the industry for the time being, but it may be short in the future.
Therefore, there is no need to rush for a while, you can slowly replace copper coins with banknotes.
As long as the people find that the use of banknotes has not affected their lives, they will no longer reject the use of banknotes.
The credibility of the Dahua court is much better than that of the previous court, and the people trust the court more. Therefore, the implementation of banknotes is very smooth. It only takes a little more time. In the future, not to mention copper coins, even silver coins will be replaced by banknotes.
