Chapter 339 One Billion New Dollars
In theory, it is really possible to make something like a bird fly into the sky.

Huang Chengyan was shocked again.

He also knows the magical effect of mechanism techniques, such as steam engines, which can still be touched and seen.

He really didn't dare to think about flying in the sky. He didn't expect Xu Ding to say that it was possible.

Huang Yueying was a little disappointed. It turned out that this could only be theoretically feasible, but it couldn't be done.

"However, the steam engine is not good, but the internal combustion engine is feasible. The internal combustion engine is a kind of power machine with a more complicated structure. If you install it, you can fly into the sky with reasonable wings." Seeing that Huang Yueying was a little disappointed, Xu Ding sent another An artifact spoke out.

internal combustion engine?
What is this?
Huang Chengyan was really confused, he didn't know many things anyway, but Xu Ding could always come up with some special clever things.

"To put it simply, the steam engine uses the pressure generated by the boiling of water to convert it into kinetic energy for transmission, while the internal combustion engine uses the heat energy generated by burning oil to convert it into power and transmits it. The output power of the internal combustion engine is much larger than that of the steam engine, and its weight is heavier Light, so it will be another world-changing product after the steam engine, of course, I don’t know how to get these things for the time being, I hope you can get them out when you get old.” Xu Ding dug a hole and said to Huang Chengyan with a smile .

Huang Chengyan was listening with great enthusiasm. An oil-burning machine converts heat energy into kinetic energy, and there is no end to end, and then Xu Ding will let him do this kind of thing.

This is the rhythm of wanting to develop him as a long-term worker to death.

Huang Yueying burst into a smile when she heard the words.

I don't need to think about things like internal combustion engines for the time being, it feels more mysterious than steam engines.

Flying dream, how can it be so easy to realize.

"Okay! Okay! If you can't fly to the sky, you can't fly to the sky. A steam engine is enough for me to work for most of my life. You leave this matter to Yueying, and I don't care." Huang Chengyan directly quit, he He came here to enjoy the blessings, and he wanted to marry his daughter off early, but it turned out that she was not married yet, so all these years of work were wasted.

loss!

Big loss.

"Uh... well, it's okay not to do it for the time being, first let the steam engine play its fullest role, and it will be enough for us to do it for decades." Knowledge structure, it is a blessing to be able to tinker with the steam engine. It is really embarrassing to figure out the internal combustion engine. This will be done by Donglai's new students in the future.

However, when he thought of Feitian, he rolled his eyes and said: "However, it is actually very simple to think of Feitian. You don't need a complicated machine. You only need a ball, a large hanging basket and a heating device. I call it Hot air balloon, let’s go, sister Yueying, I’ll take you to do a thermal test and tell you the principle.”

The principle of a hot air balloon is very simple, that is, the hot air is lighter than the cold air, so it can generate buoyancy.

All you need is a through pipe, and a fire is burned underneath, and the hot air generated enters the ventilation pipe, and light objects are placed on the pipe, and the light objects can float on the top of the ventilation pipe.

Simple and clear test.

"So that's how it is. It's easy to make! Yueying and Bokang will study it slowly and get it out soon. I'll take this hot air balloon and fly up to see what it feels like to touch the clouds..." Lao Huang It is good to understand the principle of heat, nodded frequently, and then walked away with his hands behind his back.

This is the case with everything, and once you understand it, it doesn’t seem advanced.

Lao Huang thinks that his steam engine is more powerful, so let his daughter do things like hot air balloons for children.

Thinking of such a big guy like a steam engine hula hula rumbling, Lao Huang is proud and excited, this is what real men play.

Taking advantage of Huang Yueying's skill of making a hot air balloon, Mao Jie came over.

"My lord! You asked me to come here because there is something important." Now Weiyuan Island is mainly in charge of Mao Jie, and now he has become the general manager. The military, government and civilians on the island have to take care of everything, and they are usually very busy.

Xu Ding put down the embedded knife in his hand, then pointed to the table not far away, the two went to sit on it, Xu Ding wiped his sweat and said:

"How many new coins have we minted now?"

Weiyuan Island is rich in copper. There are several large copper mines on the island. Xu Ding has been digging and refining since he obtained the smelting technical materials.

After so many years of continuous excavation and refining, it can be described as piled up like a mountain. There are ten underground warehouses for storing copper alone.

Xu Ding has long been planning to use brass coins to mint new five baht coins.

The front side is the same as the original money engraved with the word five baht, and four new characters are added on the reverse side. A circle of gear-shaped regulations is added to the inner and outer sides of the round edge of the money to prevent someone from intentionally wearing and cutting it.

"My lord is about 20 billion!" Mao Jie asked after the report was over:
"My lord, are you going to carry out the economic warfare you mentioned?"

Mao Jie was sure that if all the brass on the island was cast into five baht coins, the whole man would be stunned, even if the money of all the families and common people in the whole man was combined, it would not be as much as Weiyuan Island.

So precisely because of this kind of confidence and such economic strength, none of the early generals and civil servants who followed Xu Ding betrayed him. This is not only because of loyalty, but also because of the strength of Weiyuan Island.

Xu Ding nodded: "Basically, the money is mainly used to buy supplies and food from the states and counties. By the way, any new money with gear wear is not allowed to be circulated under our control, but you can go to the government to exchange for new coins."

The texture of brass is brighter and more lustrous than simple cylinders, it is not easy to oxidize and discolor, and it is also harder and harder to wear, so it is more suitable for circulation transactions.

The reason why brass is superior to ordinary copper is that it contains zinc.

The copper content of the brass that is allowed to be used is about 60.00% to 75%.

Therefore, the copper content of the new currency has actually dropped by 20.00%35 to about [-]%.

In this way, even if the bad money drives out the good money, the new money also has an advantage, not to mention the possibility that some speculators will melt the new money to make the old money and seek the price difference.

If they really do this, then 100% will suffer and cry.

Of course, it is inevitable that the consumption of zinc ore is not small.

However, there is no need to worry about this aspect. China is a big copper-deficient country, but it is not a zinc-deficient country.

According to the land area of ​​later generations, China's zinc mine reserves are huge, ranking second in the world.

At the same time, it occupies the fourth place among the major domestic minerals.

Most of the zinc mines in Shandong Province in later generations are distributed in Jiaozhou Peninsula.

Jiaozhou Peninsula is now Donglai County and Beihai Country.

Qucheng County under the rule of Donglai has a large zinc mine mined.

Zinc ore is a half-life ore, mainly together with lead, so it is also called lead-zinc ore.

The main use of zinc in later generations is mainly to make batteries.

Now Xu Ding has not yet developed into electricity, so the zinc produced is completely useless, it is better to add copper to smelt brass.

So Xu Ding naturally didn't have to worry about the lack of zinc, and could boldly mint new coins.

In the event that a large amount of zinc is really needed one day, the new coins can be withdrawn and the mainstream currency of silver coins can be used instead.

Of course, first of all, he has to find a large silver mine, so that he can carry out the second currency reform and upgrade.
