Time and Space Trading: I exchange a bottle of water for nuclear fusion

But even in the excitement, he has not completely lost his mind, but instead asked:

"According to the law of conservation of mass, this thing consumes a lot of energy, right? What is the energy supply?"

"It comes with a small fourth-generation nuclear fusion reactor inside. The helium-III stored in the reactor is enough for it to run at full capacity for five years. If calculated, it can produce nearly a million sets of heavy-duty exoskeletons." Frost Star spread his hands:

"After all, this thing is specially designed for the wasteland world. The purpose is to allow people to produce things with the most basic raw materials even when they have nothing. The problems you worry about basically lie with its designer. within the scope of consideration."

"If you have to talk about the problem, it will be about five years later. If you can't get high-purity helium-III, the reactor shutdown probably won't work."

Su Yu nodded, and after pondering for a moment, he tentatively said:

"So you're going to sell it to me?"

"Of course, otherwise why would I tell you so much?" Shuangxing gave him a strange look.

......

Chapter 16 A Big Deal?

"Since you said that the heavy exoskeleton was a good thing that you used as the main force of the army before the war, then you probably lack it yourself?" Su Yu asked curiously.

"Of course it's missing, but does it conflict with whether I sell it or not?" Shuang Xing sneered and said:

"There are regulations in the future city that all loot obtained during the process of cleaning the shelter must be handed in."

"I discovered this thing by accident, and I put it in the inventory of the platform, and no one else knew about it."

"If I take it back and use it for myself, it will still have to be confiscated if someone discovers it. I won't get any benefits, so why don't I just sell it to you? Anyway, I have powered armor, and I don't need it."

Su Yu: ...

Well, the reason is very real.

Compared to handing over to the future city, you can't even get a single hair, so it's really better for Shuangxing to sell it to him.

"Then what price are you going to sell it for?"

"One hundred tons of fruit, vegetable and beef each, and five hundred tons of grain." Frost Star shrugged and stated his conditions.

Gone?

Su Yu was startled.

Not expensive, but cheap!

Too cheap!

You must know that at the time of the transaction yesterday, that small pistol was worth ten tons of fruit, ten tons of vegetables, and ten tons of beef!

This black box, not a fool knows, is much more valuable than that broken pistol.

The result is this?

He wanted to ask Shuangxing if there was something wrong with his head.

But after thinking about it, is it not good for people to sell it cheaply?

Dang even shut up and agreed to the deal.

The two parties agreed that after signing the contract, Su Yu could take this thing away, as long as the payment was made within the agreed time.

Looking at the big baby in front of him, Su Yu felt like his mother was dreaming.

It's hard to make money!

But just when Su Yu was immersed in the joy of making money, Shuang Xing, who had signed the contract on the other side, also showed a relieved smile, and said in a pleasant voice:

"Happy for a while, we can talk about another cooperation now."

"Another cooperation?" Su Yu was startled:

"What good things do you have?"

"Of course there is!" Shuangxing didn't know when a palm-sized black cuboid appeared in his hand, and he threw it on the table in front of Su Yu:

"Metal hydrogen battery, the energy supply module of mechanical exoskeleton."

"Such a battery is enough for a heavy-duty exoskeleton to run continuously for 900 kilometers with a load of one ton and full power. The energy contained in this battery is about [-] times that of gasoline of the same volume."

Su Yu was stunned for a while when he heard the words, then turned his neck a little stiffly and glanced at the huge black box beside him:

"So, this thing only produces exoskeletons, not batteries?"

Don't even think about it, the energy consumption of this thing is absolutely astronomical.

In fact, if you want to build this kind of exoskeleton in reality, although there are big problems in materials or design, you can always overcome it if you are willing to spend ten or eight years.

The biggest problem is energy!

The energy that can drive such a big baby to work for a long time is too difficult to find.

The energy density of Bluestar's lithium-ion battery is only a few tenths of that of gasoline, and a large ten-liter battery on the back is not enough to make this heavy exoskeleton a few times.

And this thing is going to be on the battlefield. If someone shoots the battery on the battlefield, with the instability of the lithium battery, I'm afraid I'll burn myself directly.

As for gasoline, that's even more ridiculous.

Carry a big fuel tank on the battlefield, so why not drive?

"This black box only produces exoskeletons, but there is also a black box next to this black box that specializes in the production of supporting batteries, but unfortunately, that one has broken down." Frost Star spread his hands and said slyly:

"But if it's not broken, I won't sell it to you."

"My family is the largest battery supplier in the future city, and that thing is of great use to me."

"If you want batteries, you can buy them directly from me!"

"Price?" Su Yu sat back in his seat expressionlessly.

Damn, this woman is really not a good person!

Fortunately, he still felt that people would not do business.

Now it seems that it is a shame for her to be the commander of the regiment, and she is too fucking good at doing business!

Food was just what she needed before, and the things she could give, apart from the gold for the first time, the combat uniform and guns for the second time, were actually the best for Su Yu, and it didn’t matter if she didn’t have them. of.

In this way, when negotiating the price, Su Yu will always be the strong side.

She has no room for bargaining.

But Shuangxing simply created an immediate need for Su Yu without knowing what Su Yu had just needed.

It's as if the price of cabbage sold Su Yu's aircraft-making technology, but not his aviation fuel refining technology.

You can build an airplane, but you can't fly without oil!

In the future, if you want batteries for the exoskeleton made by Su Yu, you have to ask her to buy them.

In this way, Su Yu has the food that Frost Star just needs, and Frost Star has the battery that Su Yu just needs.

There are things that restrict each other on both sides, and no one can sit on the ground and raise prices.

"One ton of rice, three fully charged batteries." Frost star reported a number after deliberating for a moment.

After the experience of being overly cautious in the first gold quotation, Su Yu heard the price she quoted, and without thinking about it, he opened his mouth and said:

"One ton of rice has two hundred batteries, which need to be fully charged."

"Deal!" Shuang Xing happily signed the contract in front of him.

Su Yu: ...

A ton of cheap rice is only two to three thousand dollars. If you exchange two hundred metal hydrogen batteries, the average cost of a battery is about ten yuan.

Compared with the terrifying energy density of metal hydrogen batteries, the profits here are unimaginable.

After all, if you can get a lot of batteries, it can be used not only for exoskeletons, but also for too many places, such as those new energy car companies that are in full swing.

The current new energy vehicle photoelectric battery is only a few hundred kilograms, but the battery life is only a few hundred kilometers?

Come, come, let me change the battery for you. It weighs a few kilograms, and the range will reach [-] kilometers after the change.

The battery is [-] yuan, can you buy it?

This is almost a question that you don't have to think about. Those car companies can smash the threshold of his family.

However, look at Shuangxing's complacent look.

Su Yu's heart was blocked.

Actually think about it carefully.

The main component of metal-hydrogen batteries is hydrogen, which is the most common thing on any planet. As long as the technology is in place, it is worthless at all.

The future city, which inherited some pre-war technologies, certainly has no shortage of related technologies.

But in Bluestar, where the electricity price is not cheap, it is not a small expense to fully charge such a large-capacity battery.

But there is a small nuclear fusion reactor in any black box in the wasteland world, and electricity is probably the least valuable thing in her place.

Same as the last time I traded gold.

It is obvious that she has made a lot of money, but seeing her so proud, Su Yu always feels that she is not doing well, as if she is losing money.

However, the water that was spilled out of what was said naturally has no room for repentance.

He immediately signed the contract.

The contract stipulates that in the next five years, grain will be used to trade batteries once a week, and the amount of the transaction will depend on the situation.

As for five years later... I will renew the contract if necessary.

......

Chapter 17 Absolute Defense!Black eat black?

At seven o'clock in the evening, Su Yu who came out of the trading platform let out a sigh of relief.

The fruits, vegetables and beef in his inventory were gone, but there was a black box and two thousand metal hydrogen batteries.

If it is said that what he traded with Frost Star before was something that would allow him to earn some money and defend himself.

Then this black box and metal hydrogen battery belong to the future technology that can truly shake the world!

A heavy-duty exoskeleton capable of carrying one ton and running at a speed of one hundred kilometers per hour will undoubtedly rewrite Blue Star's war mode.

The laurels of the king of tank warfare will even be challenged.

Metal-hydrogen batteries, whose energy density is 900 times that of gasoline, will set off an unprecedented energy revolution.

The entire Bluestar energy industry will be shocked!

......

Seeing that it was still early, Su Yu did not rush to the abandoned industrial park in the suburbs, but took a stroll around the logistics center.

Spend a lot of money to purchase some rare metals and steel in the warehouse of a metal smelting company.

These things can be regarded as strategic materials, and it is not easy to buy in large quantities, but it is not difficult to make a little of the same, as long as he is willing to spend money.

In less than half an hour, he collected all the materials needed to build three heavy-duty exoskeletons.

The black box was taken out and placed in the warehouse. After pressing the power button, the original square black box was transformed into a small black house covering an area of ​​about 100 square meters.

Fortunately, this warehouse is big enough to accommodate this small house.

Su Yu threw the prepared materials into the material inlet.

Then he waited silently at the discharge port.

Only about 3 minutes later, a heavy mechanical exoskeleton was sent out from the discharge port.

It is indeed a fool's operation.

There is one thing to say, as long as the chimpanzee is taught to recognize the material, this thing can really be operated by a chimpanzee.

Su Yu stepped forward and touched the armor of this heavy-duty exoskeleton, and he could even feel the residual heat on it.

This exoskeleton is equipped with super-powerful motors on various joints, and the main structure is several titanium alloy skeletons.

If you don't look at the armor on the outside, it's actually not much different from the crude-looking exoskeletons on Blue Star.

And if you add that layer of thick alloy armor, it is pure black technology.
