In addition to ultra-high-definition astronomical telescope technology, there is also a technology price that is comparable to ultra-high-definition astronomical telescope technology, that is, the room temperature copper-based superconducting chip technology.

Because this foundation, like the previous ultra-high-definition astronomical telescope technology, also requires 0.01 nanometer-level, ultra-high precision CNC machine tools.

In addition, to realize this technology, we also need a device that is far beyond the technological level of Wang Bin’s era, that is, a lithography machine with a precision level of 1 nanometer level.

Therefore, with the current capabilities of Wang Bin and his Tiangong Technology, as well as the energy coins in his hands, there is no need to think about this technology for the time being.

In addition to these two technologies, with the energy coins in Wang Bin's hands and in reality, their Tiangong Technology and the overall technological level of human civilization in reality, and the ultra-high precision CNC machine tool technology are also not necessary to think about it for the time being.

Even if he had enough energy coins to buy this technology, it would be impossible to realize it in a short period of time. At most, what can be achieved in a short period of time is only to upgrade the domestic ultra-high precision CNC machine tool technology to the top international level.

However, if you just upgrade the ultra-high precision CNC machine tool technology to the top international level, you don’t have to buy technology from the system at such a high cost.

He believes that with the country's current emphasis on these aspects, even if he does not need to purchase technology from the system, China's ultra-high precision CNC machine tool technology may reach the top international level in a short period of time.

For example, the ultra-high precision CNC machine tools in the precision workshop of Tiangong Technology in Wang Bin and others are actually not very different from those of the same type of foreign products in terms of precision only, but there is a big gap in other performances and we need to continue to work hard.

In fact, among the technologies Wang Bin chose from the system, there are not many of them for him to choose from. These technologies are copper-based superconducting battery technology, copper-based electromagnetic catapult technology, copper-based superconducting coil gun technology, and copper-based superconducting rail gun technology.

Wang Bin looked at the only four technologies left in the system, thought about it and eliminated the copper-based superconducting battery technology, because whether it is electromagnetic catapult technology, coil cannon and orbital gun technology, in addition to its own technology, these technologies include superconducting battery technology, that is, supercapacitance capacitor technology.

Although Wang Bin wants all the remaining three technologies in the system, but with the energy coins in his hand, he can only buy one technology now? This makes it difficult for him to choose.

At the same time, the price of these three technologies in the system is not cheap. Among them, the price of superconducting electromagnetic catapult technology is 180,000 energy coins, the superconducting coil gun technology is 160,000 energy coins? The superconducting rail gun technology is 200,000 energy coins.

After thinking for a while, Wang Bin still chose the highest priced copper-based super-guided rail gun technology among these three technologies. However, just when Wang Bin just bought the copper-based super-guided rail gun technology, the prices of the remaining two technologies in the system changed suddenly.

Among them, the price of superconducting bomb fire technology has dropped from 180,000 energy coins? It has suddenly dropped to 80,000 energy coins, while the price of coil cannon has dropped even more thoroughly, from the price of 160,000 energy coins to the price of only 60,000 energy coins.

It is obvious that from here we can see that? In superconducting bomb launch technology, superconducting coil gun technology and superconducting rail gun technology? Many technologies are common, such as the super-large capacity superconducting capacitor technology required for superconducting rail guns? They are used in the other two technologies, or in other words, these three technologies are based on super-large capacity capacitance technology.

Although the price of the remaining two technologies is now reduced by more than half after he purchased the copper-based super-guided rail gun technology, he still cannot afford to buy any of them with the remaining energy coins in his hand.

Because the energy coins left in Wang Bin’s hand now are only less than ten thousand energy coins left.

After purchasing superconducting technology from the system, Wang Bin withdrew from the system and returned to the store of the Technology Mall. However, he did not return to reality. Instead, he quietly thought about the copper-based superconducting electromagnetic railgun technology he had just obtained from the system.

Although the railgun technology purchased from the system is called railgun technology, it is not actually the case. In fact, this is a complete set of technologies, including ultra-micro-rail gun technology that can fire projectiles with a diameter of only 0.1 mm, and ultra-large-diameter railgun technology that can fire projectiles with a diameter of more than one meter or even larger.

Of course, with the current strength of Wang Bin and Tiangong Technology, it is still impossible to manufacture such an ultra-large caliber rail gun, because according to the technical instructions given by the system, it is not an easy task to manufacture such an ultra-large caliber rail gun.

First of all, in terms of time, because the energy required for such a super rail gun is amazing when firing once, the super capacitor must be manufactured first.

Although the technical principles of supercapacitors are the same as those of small and medium-sized capacitors and are not technically difficult, their volume is very huge, covering an area of ​​hundreds of meters and a height of dozens of meters.

The most important thing is that the entire supercapacitor requires copper-based room temperature superconducting materials to be made. It is conceivable how much copper-based superconducting materials this requires. This alone can make Wang Bin and his Tiangong Technology bankrupt.

What's more, if it were just such a capacitor, it might be possible to make it, but a super-large-caliber rail gun requires as many as five super-capacitors.

The second is that the energy required to fire such a rail gun is not supported by ordinary civil or industrial electricity. It must be supported by professional power plants. Of course, nuclear power plants are the best.

Therefore, although Wang Bin has the technology to make super rail guns in his mind, it cannot be achieved in a short period of time.

Of course, if such a super electromagnetic railgun is manufactured, its purpose is quite good. Not to mention that if such a railgun fires at the maximum energy, its firepower will definitely be enough to cover any place on the earth. This is an absolute huge deterrent to any country on the earth.

Secondly, with the ability of such an orbital gun, it can definitely drive any item weighing less than ten tons directly from the ground into space orbit.

In other words, if there is such an orbital gun, satellites with less than ten tons will not be launched without rockets. Using such an orbital gun directly can drive the satellite into orbit, which will definitely save countless funds in terms of launch costs.

Therefore, such orbital guns are of great use and can even be used to deal with threats from outside the earth, such as asteroids and comet meteorites.

Of course, with the ability of Wang Bin and his team of Tiangong Technology, although they are unable to manufacture super-large caliber electromagnetic railguns.

However, there is no problem in manufacturing rail guns with a diameter of less than 200 mm, especially rail guns with a diameter of less than 100 mm.

At the same time, manufacturing track guns with a diameter of only a few millimeters or more than ten millimeters will naturally be no problem.

After browsing the technology in his mind for a while, Wang Bin was generally very satisfied with the technology he purchased this time, so he quit his mind.

However, when he quit his mind, he found that in his Tiangong Technology store, there were people in the store besides himself. The most important thing is that although this customer is not a customer who has visited them Tiangong Technology before, he is very familiar with it because this customer is Tony, one of the protagonists in a certain American comic!

Seeing Tony in Wang Bin's shop at this time, Wang Bin suddenly became excited. This is the famous Iron Man! As long as he can stabilize this customer, it is definitely not a problem to obtain some technology from the universe where he is located in the future. Not to mention other things, just the technology owned by Iron Man himself is worth Wang Bin to win him at all costs now.

The most important thing is that in the world of Iron Man, there are anti-gravity technology and cold nuclear fusion technology! These technologies are key technologies for the promotion of civilization level, and Wang Bin is absolutely impossible to give up these technologies.

So he immediately went up and said to Iron Man: "Hello! Welcome to our Tiangong Technology Store."

Hearing Wang Bin's words, the Iron Man did not speak, but just nodded to Wang Bin and continued to wander around his shop.

At the same time, Wang Bin also saw in the eyes of Iron Man that he was very disdainful of most of the products in the store. It was obvious that in his eyes, most of the products in the store could not reach his eyes. It was obvious that this technology was basically backward technology for him, or for the world where he was located.

After watching quietly for a while, Iron Man picked up a piece of special high-temperature resistant glass and looked at it. It was obvious that he was still interested in special high-temperature resistant glass. But thinking about it, according to the system's evaluation, the glass he obtained from the system before was a reward for the system, so the technical level of these glasses is relatively high, so Tony is not difficult to understand.

After looking for a while, Tony said to Wang Bin: "Shopkeeper, except for the interesting glass in this store, everything else is meaningless to me."

Speaking of this, Tony thought about it and said directly to Wang Bin: "Give me ten tons of glass!"

"Okay, this gentleman doesn't know what type of special glass you need?" Wang Bin asked.

Afterwards, Tony selected more than a dozen models of flat glass from Wang Bin's store and paid for it to leave.

Wang Bin was not angry about Tony, after all, who said that the products in his store now are basically ignored by others! Fortunately, he doesn't like all the products, at least he still needs special glass.
Chapter completed!
