Lao Hong is very poor.

Don't look at the dominance in North America, but when you come back, you are destitute.

Thirty million Franklin were 'confiscated'.

The oil tanker and oil barrel were handed over to the evil boss to repay the company more than 2.5 million foreign exchange.

I finally brought back two boxes of Cuban cigars, and they were detained by customs.

I originally brought a box with me, but then I rummaged through my pocket, and it was gone!

What makes Lao Hong even more uncomfortable is that going abroad this time is not official business.

Therefore, you need to pay for the ticket from your own pocket.

In addition, he missed his salary and was absent from work this month, according to Tiancheng's strict management system, he not only worked for nothing this month, but also had to pay 1,600 yuan at the end of the month's 'lost work fee'!

I used to feel that Tiancheng's salary was very good, but now I find that there are pitfalls everywhere.

Today, he invited the boss to visit the scientific research results, and he was thinking of taking a red envelope to buy cigarettes and smoke ......

I didn't expect this crude tin box to make a lot of money!

In an instant, Lao Hong thought of encouragement awards, project dividends, and sales commissions......

"What are you foreigners going to do?"

"Run!"

"Print Animated Poster...... What? Infringement? Those devils from Wadao Island will come to our small county town?"

"That's right, forget about the animation in North America, I don't guarantee that there are two or five of you, shoot a news and send it back to North America!"

"What anime?Ikyu, Gundam, Bhikachu, Pachin, Digimon, Blitzka......"

"Audio, find the Chamber of Commerce!"

"Colorful lanterns, looking for KTV!"

"Motherboard? Who was the OEM before? Now it's all mass-produced, place an order!"

After a blind command, Lao Hong suddenly thought of a very important question, and hurriedly ran to Ge Xiaotian, who was observing everywhere, "Boss, what about the coin dispenser?"

"Did you go out and lose your brain?"

"How is that possible, or ...... IC card?"

"The soul of the crane machine lies in the coin, the metal coin falls, the card is chaotic, the passionate music follows, the excitement is immediately raised, and the card has this function?!"

"Well, if you say a coin-dropper...... We can do it, and we can do it with a coin reader, but molding, production, and coinage ...... It is estimated that it will take more than half a month......"

"Are you stupid? Computers are popular, little eight kings are thieves, look at those game halls in Xiang County, are there still people? Go around the surrounding counties and cities, and say that you will immediately crack down hard, comprehensively rectify the entertainment venues, and not allow game halls to be opened in the future! You take the opportunity to 'recycle' arcade machines at a high price, and it is estimated that you will be able to bring back a large number of them on the same day!"

"I see!"

"Buy it back and dismantle it, the joysticks, buttons, and stereos are all ready-made, and you can use them after refurbishing! Keep the electronic screen, integrated electric board, and controller, and make a retro project in the future!" Ge Xiaotian originally planned to throw coins directly, but in the millennium, one dollar at a time, it is estimated that no one can afford to play, "including the coin inserter and the coin reader, all of them are copied!"

Lao Hong took a deep breath, worthy of being an evil capitalist, "However, most of the game currency is universal, and others bought the game currency from outside......"

"I remember that the coin reader should be infrared induction, the game currency falls, the coil is energized to produce a magnetic field, the magnetic field penetrates the game currency and transmits to another coil, the current is the real game currency, and if it is not inducted, it is a fake game currency, mainly because of the material of the metal plate, if you adjust it, wrap the game currency in a half circle of plastic shell......"

"Dear Godfather, this recognition function is a bit backward, I recommend using letter recognition!" "Jinx, the head of scientific research, happened to be passing by, heard this, and opened his mouth to propose.

"Oh?" Ge Xiaotian was a little surprised, now that technology is so advanced, "Do you need to redesign the coin dispenser and identifier?"

I used to play arcade machines a lot, and I also helped others improve the coin reader, just add a small device, it's very simple!"

"Add letters to the original game currency, the pattern is so messy, and the recognition ability is estimated to be ......"

"No, it's on the outer edge of the coin, which is the side that stands up, and you can engrave 'hong' with a metal burner!"

God is so special, Ge Xiaotian corrected: "Tiancheng!"

"Yes boss, Tiancheng!" Jinx looked respectful and reverent.

“......”

It seems that this thing is deeper than the poisoning of those five fat boys.

Ge Xiaotian looked at Lao Hong, "Don't be too high in the recognition ability of game currency in the early stage, specifically attract people with bad intentions to grab dolls with a large number of foreign game coins! Don't you make a remote control system? In this way, won't our game currency roll in? Turn around and engrave the word Tiancheng, it will be ours!"

Lao Hong was silent for a moment, "It's a little difficult!"

"What's hard?"

"Counterfeit money can be played!"

"Damn, you're still engaged in electrical? I can think of a way for a layman, but I can't think of it?"

"Boss, I'm smart, I understand!" Jin Xun completely offended the confused Lao Hong, "Generally speaking, the identified genuine coin will enter the next procedure." The boss means that let's make a 'pseudo-identification' motherboard in the counterfeit currency channel, or rather, make a program that can play any currency, cast 'counterfeit money', start this machine, it can move its claws, and it can also be grabbed, but there will always be various accidents, such as the claws are loose, caught in advance, shaking badly, and the speed is too fast...... In short, it is very difficult to operate! Others play with real money, and when they catch one accurate, they use fake money to play, but they can 'decay' to the point of doubting life!"

"Brilliant!" Ge Xiaotian gave a thumbs up, "Jinx, I suddenly admire you very much!"

"Thank you boss, I'll do my best!"

..................

With the plan in place, the crane machine project unfolded quickly.

Soldering cabinets, assembling tracks, negotiating integrated circuit orders with component manufacturers, and perfecting game programs......

In less than the evening, the Ministry of Machinery pulled a batch of arcade machines from the Jishi Cultural Bureau that had been seized a long time ago.

Dismantling, induction, packaging, and sending in batches to Daqingshan Tiancheng station for reconstruction......

A busy night.

At noon the next day, Ge Xiaotian took the lead in sitting in front of what may be the world's first crane machine.

Well, here's the sample.

Lao Hong and others watched one after another.

As a maker, you must know how to play, and you have already installed the anime puppets in advance.

"Have you counted? How much does this one cost?"

"About three hundred!"

"So tall?"

"Iron sheet, steel bone, integrated circuit, R&D program ......"

"By the way, how much?"

"More than two hundred pounds!"

"It's too heavy, what if it falls down and hurts people?!, and the cost is also a bit high, replace the iron cabinet with the fiber plastic we use to build cars!"

"In this case, the cost should be reduced to two hundred, and the weight should be ...... Less than one hundred and fifty pounds!"

"Almost!" Ge Xiaotian dropped the sample game currency.

Flash-la, drip-slip, and brilliantly lit......

Control the joystick, tap the button, rotate the claw, and beat it in a row......

"No, when you're about to grab the doll, you have to add another 'Hold On' program!"

"Are we going to die?"

"How many people will play in the early stage? Gradually increase the difficulty, and then launch different styles and sizes of dolls, and the claws should also be different in size, such as key pendants, sweater pendants, etc., all with small claws!"

"Got it!"

"Today is the thirteenth day of the first lunar month, and twenty units were made before the Lantern Festival, half of which were placed in the Crescent Moon Children's Entertainment City, and half were placed in Xiaoqingshan Supermarket!" Speaking of the supermarket, Ge Xiaotian suddenly thought of another coin-operated child killer, "I remember what kind of old-fashioned sand sifting machine we had at the construction site before, which is similar to the kind that pounds sesame oil, is there still one now?"

"No, now all the crawler sand screening machine is used, and you can mix it directly in one go. ”

Ge Xiaotian took out a pen and paper, "Change the old-fashioned sand sieve machine, add a small car model, or zodiac, locomotive, elephant, etc., shake it slowly back and forth, and then add different types of children's rhymes, and also use this kind of coin dispenser to cast once for five minutes!"

"It's simple, all the old machinery is piled up in the warehouse, sorted out, and it can be modified. ”

"Be sure to pay attention to safety, the motor must be replaced!"

"Yes!"

..................

After a busy day, in the evening, Ge Xiaotian returned to the crescent office.

Coincidentally, the BYD manufacturer, which had been silent for two days, also sent a letter of intent for cooperation.

The other party is very sincere, not only considering the load problem of electric vehicles, but also listing the impact of temperature changes on the battery in spring, summer, autumn and winter.

It's just that with the data like a ghost drawing, Ge Xiaotian is dizzy.

After being silent for a long time, he looked at his secretary:

"Xu Ling, what about the junior high school physics textbook I bought for the self-exam?"

"In the second cabinet on the left!"

Rummage.

Finding chapters about current, capacitance, voltage, and power from the textbook, Ge Xiaotian saw the early hours of the morning before he figured out Ah, mAh, kWh, Wh, Kw, V, and vAh...... and so on, the relationship between them, and the corresponding formulas.

Drink a cup of tea to digest and digest, then pick up a pen and paper and start calculating.

At present, there are two types of cheapest power batteries in the market: nickel-cadmium batteries and lead-acid batteries.

The price given by the partner is definitely far lower than the market price, with an average of 0.3-0.5 yuan/Wh.

Nickel-cadmium batteries are toxic and cannot be used.

Lead-acid battery ...... It also seems to be toxic, but this is the mainstream in the world at the moment.

Write, write, draw.

Take the previous battery-powered bike as an example:

400 batteries, 800 pieces, 7Ah.

Suppose Tiancheng spends 800 yuan in red money to buy a lead-acid battery pack, 1600Wh.

According to the output voltage of 48V, 1600Wh/48V is equivalent to about 33Ah.

One 7Ah, one 33Ah.

The comparison of numbers can fully explain how expensive Lao Hong's battery pack is.

Calculate the trip again.

Let's assume that the motor power is 350W.

Average velocity average current: power/voltage = 350W/48V = 7.3A

Travel time = battery capacity / average current = 7Ah / 7.3A, which is about 0.96h.

According to the speed of 30Km/h, the theoretical travel = 0.96hx30Km/h = 28.8km.

However, the journey is affected by the load, temperature, and the absence of a battery control system, so it will end up being about 20 kilometers.

Lead-acid battery pack is applied.

Travel time = battery capacity / average current = 33Ah / 7.3A, which is about 4.5h.

According to the speed of 30Km/h, the theoretical travel = 4.5hx30Km/h = 135 highways.

One is about 20 km and the other is about 135 km.

Even if the load and temperature have a great effect, the difference between the two strokes is as high as six times.

However, lead-acid batteries have a big disadvantage, the same capacity, don't look at Lao Hong used 400 lithium-ion batteries, but the volume and weight are only one-third of the lead-acid battery!

This gap, if placed in cars, buses, is almost negligible, if placed in electric vehicles, plus toxic ......

Ge Xiaotian looked at the second document given by Beati.

This is a lithium iron battery that the other party is developing.

Judging by the full name, there are some impressions.

It seems that the electric bicycle I bought before squatting in the iron window used a lithium iron phosphate battery.

Small in size, durable, and the world's future mainstream energy source.

The initial quotation given by Biati is: 4-5 yuan/Wh

Ge Xiaotian calculated again.

800 yuan, you can buy 160Wh, divided by 48V, 3.3Ah!

More than double the price of the lithium-ion battery pack assembled by Lao Hong!

Leave!

With a little melancholy, Ge Xiaotian looked at the time, it was already one o'clock in the morning, "Huh, Xu Ling, why haven't you gotten off work yet?"

"I'm afraid you have something I need to deal with. ”

"Everything that should be arranged has been arranged, what can happen......" Ge Xiaotian wanted to say that he would go back early, but it was all at this point, "By the way, where do you live with Brother Liu?" (work with Lao Qin to be the project manager of the duck)

"I live in the small high-rise that Mr. Qin bought in Area C. ”

"It's not renovated, is it?"

"Fitted with a window and door ......"

"It's freezing, what's the matter!" Ge Xiaotian rummaged through the drawers and found a bunch of keys, "Building 801, Building 1, Area A, should be renovated, you move in first, if you feel okay, I will send you as a wedding room!"

"No, no, boss, it's too valuable!"

"What so much nonsense!" Ge Xiaotian said, throwing the key over.

As a developer, each development will have a batch of houses in case of emergency.

At the beginning, there were ten sets left in Xingyue Bay in Xiangxian County, and later ...... Well, what, no one wants it, and then gave it to the seventh master to deduct the gold, and he didn't want it, and finally threw it to the sky ornament to practice his hands, and it is said that the decoration is very good.

"Xu Ling, ask you something!"

"Battery?"

"Yes, the battery suitable for electric vehicles, lead-acid is OK, but it is not the kind I want, if it is handed over to others for research and development, it will take a long time......"

"Boss, I heard that our resident scientific research room is very powerful, and a new engine has been developed in a short period of time, and the performance far exceeds that of its peers, why do we want to do electric across the line?"

"The future trend is that fuel is getting more and more ......expensive," Ge Xiaotian woke up suddenly.

There are many things that replace fuel oil, such as nuclear energy, hydrogen energy, bioenergy, combustible ice, natural gas!

Why limit yourself to batteries?

A battery is nothing more than a container that can be used to generate electricity directly, or to store other light energy conversion devices......

Like the simplest 'pure ethanol engine'!

"Dididi!"

In the middle of the night, the mobile phone suddenly rang.

Ge Xiaotian glanced at the screen, and it turned out to be Yang Dingfeng, who was far away in the Far East of the Ice Bear to help deal with the tank.

"Old Yang, why are you calling now?"

"That's it!"

"Oh, thank you!" Ge Xiaotian smiled, the incident of Lao Hong and the tank was finally over!

"Hmm, why don't you ask for details?"

"It's not too late to come back and talk!"

"I'll go back and talk, but there's no one to help you deal with the big mess here!"

"What do you mean? We bought the tank and armored car, what else do we have to deal with?"

"The land you bought!"

"When did I say I bought the land?"

"At the dinner table that day, it was the time you got drunk, didn't you say you wanted to buy Siberia back?"

“？？？”

When did I say that?!

Ge Xiaotian's face was full of confusion, "No, do you always have some misunderstanding?"

"Misunderstanding a fart, my in-laws Lin Yang, my grandson Yang Lin, both of them can testify! Otherwise, it would cost tens of millions to buy a few abandoned tanks......?

“......”

"Sixty million red money, ten million Franklin, minus the tanks and armored vehicles, the rest is ...... 134 million. To buy land on Bingxiong's side, you need to find an agency, and I just happen to have it, so I won't charge you an intermediary fee. The land on their side is calculated by hectares, 100 red bills per hectare per year, for a maximum period of ten years, and a total of 150,000 hectares were bought, most of which were given by the Ice Bear Navy, saying that you have time to take a look at the 'Admiral Gorshkov' and the 'Novorosses' aircraft carriers, the original words are: cheap, brotherly price!"

......: "I'm afraid it's not that the other party looks at me stupidly and has a lot of money, right?!"

"Boy, 150,000 hectares, what are you going to plant? Although it is still early before the thaw, the ice bear agriculture is very strictly controlled, and you must prepare seeds and machinery in advance and declare them! By the way, when you send someone over, don't bring pesticides, otherwise I won't be able to help if you are investigated!"

"No, you wait!" Ge Xiaotian looked at Xu Ling, "150,000 hectares, how many acres?"

"Two million five hundred and fifty thousand acres!"

"......" Ge Xiaotian swallowed his saliva, "What does your old man suggest I plant?"

"Didn't you say planting soybeans, producing soybean oil and soybean meal, and providing Li Xiuxiu with a steady stream of pig feed!"

"......" Shen Te has a steady stream of pig feed, Ge Xiaotian asked again: "What do you propose to plant? I don't understand!"

"Potatoes, barley?"

"What do you mean?"

"Ice bears like to eat potatoes, barley, and send them back to China to make wine!"

"Wait!Brewing?" Ge Xiaotian picked up the battery he had calculated overnight, "Can you make industrial alcohol?"

"Yes, are you stupid? Sorghum and barley are the main raw materials for brewing!"

"Then plant barley and sorghum!"

"You have to send someone, how can I have so many people here?"

"When are we short of people? My people have arrived in the Northeast!"

"Sure enough, I knew you kid was going to buy Siberia!"

“......”

You are mistaken, I sent them to infiltrate Siberia, to log, quarry, and rob gold!
