Sun Lingtong hooked shoulders with the little robot with an excited face.

"Master, I can control this metal puppet! What is it called? ”

Tang Yan looked at the little robot and thought of a very appropriate name.

"Oh, it's called Gundam."

Sun Lingtong was even more surprised.

"Is the surname Gao Mingda? There is a name and a surname, is there a child living in it? ”

Tang Yan smiled and rubbed the little girl's head.

"There are no children in there. However, as long as you wear a bracelet and anklet, you can control the Gundam and make it an active child like you. ”

Sun Lingtong kept screaming, dancing with the little robot.

Sun Zihu saw that Tang Yan was happy, and hurriedly hugged his fists and congratulated.

"Congratulations, Master, this Gundam is simply ingenious!"

Kong Qingshao asked curiously on the side, "Uncle Shi, what is this Gundam for?" ”

Tang Yan looked at the little robot that was being controlled by Sun Lingtong and smiled.

"This is for mortals, who can do a lot by controlling the Gundam. For example, if you fight or something, you don't have to worry about hurting yourself. ”

Sun Zihu and Kong Qingshao looked at each other.

What!?

The things that Venerable Yuanying specially refined were actually for mortals to fight?

Although it can be driven without spells, it is amazing.

But the problem is, now that the whole people are cultivating, how can there be a few mortals.

This Gundam is not practical!

But Sun Zihu and Kong Qingshao didn't dare to say it.

The two of them boasted about Gundam in the sky and on the ground, and seeing that Tang Yan was a little impatient, they left Sun Lingtong with a special look at his eyes and withdrew.

With Sun Lingtong joining, the finished products made by Tang Yan and Yunyi in the next year have been tried.

Although the sample size of the trial is somewhat small, it is better than nothing.

The types of finished products are also varied.

There are not only simple Gundams that resemble the prototype of mechas, but also individual prosthetic limbs, controllers, microrobots, and more.

Far from what Sun Zihu and Kong Qingshao imagined, they could only help mortals fight.

The real role in modern times can be great!

After a year of experimentation and improvement, Tang Yan has been able to abandon the hand and foot rings and use a few micron biological interfaces as the interface for neuronal connection.

Since Sun Lingtong needed enlightenment, at most it would take a year for the children to help, so Tang Yan and Yunyi compressed the trial time into one year.

Due to tight timelines, the results of the trial may be biased.

But it doesn't matter, when Tang Yan returns to the present world, whether it is for rationality or to write a paper, he needs to copy the experimental process again, and there will naturally be many opportunities for experimentation at that time.

You don't have to do it all in this small world.

When Sun Lingtong reached the age of 7, he was thrown to Yunyi by Tang Yan to enlighten, and Tang Yan himself began to prepare for the second experiment.

Controlled nuclear fusion is the subject of many people's research in the modern world.

And there are already preliminary results, such as tokamak devices.

But everything is still in its infancy, and it is still a long way from being commercially available.

The commercial nuclear energy in the present world does not use nuclear fusion, but nuclear fission.

The U235 needed for nuclear fission is not inexhaustible. A large number of chemically reactive substances need to be added in the process, and the waste material is extremely radioactive. And the stability is not so good either.

Nuclear fusion is different.

The material currently used for nuclear fusion in the present world is deuterium, which is abundant in seawater and is inexhaustible.

However, nuclear fusion with deuterium is the most primary, and neutrons are produced in the process, which still has a certain degree of radioactivity.

Although the harm is not known how many times less than nuclear fission, it is still harmful.

However, if the reaction is carried out with helium-3 and helium-3, it is the most perfect state. No neutrons are produced in the process, and the harm is almost non-existent.

It's just helium-3, which is not found on Tang Yan's planet, only on the moon.

So Tang Yan is now struggling, the direction of her research should be first-order controllable nuclear fusion, or in the most perfect state.

Tang Yan's selfishness is, of course, to choose the most perfect.

However, with the existing scientific and technological forces in the world, it is difficult and expensive to mine a large amount of soil on the moon.

And the temperature and pressure required for the reaction with helium-3 are far from comparable to first-order controlled nuclear fusion.

The difference in light temperature between the two is billions of degrees Celsius.

In the information provided by the system, some of the equipment and materials required are not within the reach of modern technology.

It can be said that if Tang Yan chooses to study the controllable nuclear fusion of helium 3, he needs to find a way to solve it from raw materials to the most primitive materials of the equipment, which is too difficult!

With the information in hand, Tang Yan is not sure that he will commercialize controlled nuclear fusion in a short period of time.

Not only that, but it was also difficult to bring the results of the experiment back to the present world.

If nothing else, one kilogram of helium-3 alone will cost hundreds of millions of yuan. And to complete the whole experimental process, just one kilogram is completely not enough.

Even if Tang Yan has a good relationship with Huade Company, the other party can't invest more than a billion dollars to study a topic that sounds difficult to make a profit.

Is it that before doing the experiment, she still has to do business to make money and buy raw materials?

It's just too much trouble.

Tang Yan tugged at his hair in great confusion.

This is not actually her usual character.

If this was Tang Yan's own choice, choosing between the foreseeable success in the near distance and the more difficult but greater success in the distance, she would not hesitate to choose the latter.

But this choice is related to the livelihood of the people of a world, especially the livelihood of her own world, and it is a matter of great importance, so she can't blindly do it, she has to think about it more.

In fact, if you think about it, first-order controlled nuclear fusion is also quite good.

Although it is not perfect, it allows everyone to use the energy produced by controlled nuclear fusion much faster, which is much better than the current energy method.

And the scientific and technological span is not so large, and everyone can continue to develop controllable nuclear fusion step by step.

Perhaps in another 180 years, scientists will be able to harness helium-3 on their own.

Tang Yan stood up from the futon and patted his head with some annoyance.

Yes! It's a step-by-step process! She's so eager!

It is entirely possible to use first-order nuclear fusion first.

Then, the energy from nuclear fusion can be used as fuel to improve existing spacecraft, greatly reduce the cost of going to the moon to mine soil, and obtain helium-3 in large quantities.

Later, it slowly switched to helium-3 as a supporting facility for controlled nuclear fusion raw materials.

At that time, as long as Tang Yan commercializes first-order nuclear fusion, there will naturally be official funds and efforts for her to continue her research.

From deuterium to helium-3, technically, it will take a few years at most, but no more than ten years.

This is the most suitable development order, Tang Yan pursued too much in one step before, but his mentality was out of balance.

It's just a few years in this world, and for Tang Yan, it may be hundreds of small worlds, thousands of years.

At that time, it is not certain whether she will be willing to do research for more perfect controlled nuclear fusion.

After all, no one can say what the future holds.
