Back at the company, Tang Xiaochuan used the internal network to contact Liu Gongyou, Wang Rui, and two other high-intelligence robots responsible for the development of medical equipment and basic technology equipment. These two high-intelligence robots were named Zhang De and Qi Qiang. .

The three-dimensional virtual holographic image in the office is divided into four parts, showing the figures of four people.

"Hello boss!" The four high-intelligence robots greeted Tang Xiaochuan separately.

Tang Xiaochuan nodded: "Professor Liu, Professor Wang, Professor Zhang, and Professor Qi, in the field you are responsible for, the current level of progress should be the industry leader? But in the same industry, some companies in the same industry have their own unique research and production technologies. Where, if you get their key technology, I don’t know if it will help your research?"

Zhang De immediately said: "Of course it is helpful. We can use their technology as a reference to analyze the advantages and disadvantages of these technologies, and even remove the essence and remove the dross. If some technical details can be used for reference, we can save more. More time!"

Qi Qiang also said: "Yes, their technology has advantages and disadvantages, and they know it themselves, but if they want to only take the essence and discard the dross, they can't do it, because they have a common research direction and a set of systems; But our side is different. Our research system is different from them. We can only take the essence without affecting our research!"

Tang Xiaochuan nodded, "You and those researchers from companies in the same industry are all peers. You should be very clear about what technical research results they have. You should draw up a list of the names of the technologies you need, and where are these technologies? The company has their uniqueness, and they are clearly written, I will find someone to get it!"

"Okay, boss!"

The leaks of science and technology and production technology have existed since ancient times. The spread of the four great inventions to all parts of the world is actually a technical leak to some extent. There are also many technologies in the West that have spread to the East. Could it be said that the ancients did not have the awareness of secrecy? ?

Absolutely not. Sometimes you can't prevent it. Wars, disasters, and man-made disasters may cause the production process and science and technology to leak and spread to other places.

In the peaceful era, the biggest problem of technology leaks is the circulation of talents. Stealing technical information by theft is not the main problem of technology leaks. After all, every company has a strict security system and equipment to prevent someone from stealing technical information. It is impossible for outsiders to easily steal technical information.

The circulation of talents is inevitable. People go to high places and water flows to low places. However, because talents can circulate freely, if you want to keep the technology ahead, you can only continue to invest in capital and increase research and development efforts. Accelerated the further development and improvement of science and technology.

"Boss, there is one thing to report to you. We have made some progress in hydrogen storage research!" Wang Rui said to Tang Xiaochuan.

When Tang Xiaochuan heard this, he immediately asked: "How far has it progressed?"

Wang Rui said: "The boiling point of hydrogen is minus 252.76. There are only two ways to liquefy it. One is to control the temperature below its boiling point, or to increase the pressure! It is easier to increase the pressure, but the difficulty is to let the temperature If it drops below 252.76, even if its temperature can be lowered below this boiling point, the cost is too high, let alone we cannot afford it, even if it is used in practical applications, consumers will not pay for it!"

"If the pressure is increased, the critical temperature of hydrogen liquefaction is minus 239.96. Above this critical temperature, no matter how much pressure is increased, it will not liquefy, so it can only be pressurized below minus 239.96! Why must Let hydrogen be liquefied? Because if it is not liquefied, the cost of storage and transportation is too high, and the amount of hydrogen in each transportation is too small. Only liquefaction can make each transportation more, so that the cost of transportation and storage can be reduced. You know what I mean?"

Tang Xiaochuan nodded and motioned for him to continue.

Wang Rui continued: "But even if it is necessary to control the temperature below minus 239.96, there are still great technical difficulties. This is why until now, hydrogen has not been used as a normalized energy source in real life to serve the public. the key to success!"

Tang Xiaochuan asked: "Do you think of a way to drastically reduce costs to keep the temperature below minus 239.96?"

Wang Rui shook his head: "There is no way to reduce the cost. We can control the temperature below this critical temperature, and we can also increase the strong pressure. We have also developed a very strong container to hold it, but we still cannot reduce the cost of liquefying it! "

"Therefore, we can only take a different path and use the principle of substance-to-substance restraint. We have developed a brand-new composite gas. Adding it to hydrogen can change the physical properties of hydrogen and greatly increase its boiling point and critical temperature!"

Tang Xiaochuan stared at the boss, "How far can its boiling point and critical temperature be increased?"

"Minus 33.58 and minus 14.29!"

Tang Xiaochuan couldn't help swallowing his saliva. "So, we only need to put the hydrogen container in a refrigerator, keep the temperature below minus 14.29, and increase the pressure to make it liquefy?"

Wang Rui nodded: "Yes, that's it!"

"Wait, I'll come right now!"

Tang Xiaochuan rushed to the research center immediately after cutting off the communication. He saw Wang Rui and some research staff in the test site surrounding something like a water heater tank.

"Professor Wang!"

Wang Rui turned his head and looked, "Boss, look, this is the hydrogen storage tank we just made!"

Tang Xiaochuan came over and pointed to the jar and asked, "Can this thing withstand the pressure?"

Wang Rui smiled and said: "You can rest assured that we have done many tests. This is a brand new solid composite material, very strong!"

One end of this tank is connected with a tank, and the machine next to it is filling the tank with hydrogen gas with a pipe, and a wire is connected to the tank.

"Why is this wire used?"

Wang Rui replied: "Electrically cool down and control the temperature. This tank is like a refrigerator. There is also a tank filled with hydrogen. After the hydrogen with special synthetic gas enters the tank, it will increase when the temperature drops below minus 14.29. The higher the pressure, the more liquid hydrogen becomes!"

Tang Xiaochuan asked: "How do you know that the hydrogen in the tank has started to liquefy?"

Wang Rui pointed to a computer screen on the table next to him, "Look, this is the picture inside the jar!"

Tang Xiaochuan turned his head and looked, and he saw a hole on the computer screen was blowing air. The gas turned into a white mist after the jet, and the liquid level under the tank was getting higher and higher, indicating that there was more and more liquid hydrogen!

"What is the current temperature in the jar?"

A staff member next to another computer pointed to another computer and said, "Boss, this is the temperature change in the jar. Look! This jar-shaped refrigerator can reduce the temperature to minus 18 degrees at most. Now it is minus 16.25. More and more hydrogen is being charged, and the temperature in the tank is also rising! If the temperature rises to minus 14.29, the hydrogen will no longer be liquefied, and the filling of hydrogen can only be stopped at that time!"

After waiting for two minutes, Tang Xiaochuan found that the hydrogen filled in was no longer turning white, and the temperature in the tank was close to minus 14.29 degrees.

One worker immediately turned off the pressurized gas filling equipment, and another worker immediately closed the valve of the liquid hydrogen tank.

"Only to this extent!"

Tang Xiaochuan asked: "How much hydrogen can this tank contain?"

Wang Rui replied: “About 30 liters, which is smaller than the volume of a normal car’s fuel tank, but the calorific value generated by the combustion of hydrogen is much larger than that of gasoline. It is completely feasible!"

Tang Xiaochuan thought for a while and asked: "If this tank is to keep the temperature below minus 14.29 degrees, how much power does it consume every day? How long can our current solid-state batteries last?"

Wang Rui smiled and said: "This small refrigerator tank only needs one kilowatt of electricity for a whole day. The solid-state battery with the smallest storage capacity developed by our company can keep it running for at least two months, so there is no difficulty and pressure to install on a car. !"

After hearing this, Tang Xiaochuan was relieved, "There is another question, how safe is it? For example, after a car accident or collision, how likely is this tank to rupture? Will it explode?"

Wang Rui said: "Hydrogen tanks are wrapped in refrigerator tanks. Under normal circumstances, even if it is hit, it is the refrigerator tank outside that bears the greatest strength. The refrigerator tanks are fundamentally very firm, plus the hydrogen tank. The degree of rigidity is higher, and the direct rupture of the hydrogen tank seldom happens!"

"Moreover, it is like a fuel tank. It is generally not installed on the head and tail of a car. In order to make it safer, we can use special materials to protect it around it. This can make the blueprint. The car company will do experiments to minimize the impact of the impact, and then relying on its own ability to withstand it, there should be no problem!"

Tang Xiaochuan nodded: "Yes, the anti-collision test must be done, and it must be done thousands or tens of thousands of times to ensure that no matter how fast the speed is, what kind of crash event occurs, it can be intact! This is not the case. Just kidding, if the gasoline tank is broken, only oil will flow out. If this tank is broken, if the hydrogen in it leaks out, it will explode and explode a lot!"

"So the complete problem of this thing is the top priority!"

Wang Rui promised: "The boss can rest assured that we will continue to study storage materials, and we will continue to study how to improve the efficiency of hydrogen energy utilization and manufacturing processes, and reduce the cost of producing it, so that everyone can use it!"I can make money by swiping the video.
