Chapter 129 (1/2)

In addition to the ultra-high definition astronomical telescope technology, there is another technology whose price is similar to that of the ultra-high definition astronomical telescope technology, that is, the normal temperature copper based superconducting chip technology.

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

In addition, in order to realize this technology, we also need a device far beyond the scientific and technological level of Wang Bin's era, that is, a lithography machine with a precision level of 1 nm.

Therefore, this technology, with the current ability of Wang Bin and Tiangong technology, as well as the energy currency in his hand, need not be considered for the time being.

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

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

However, if only the ultra-high precision CNC machine tool technology is promoted to the international top level, in fact, Wang Bin does not need to buy technology from the system at such a high price.

He believes that with the state's current attention to these aspects, even without him buying technology from the system, Huaxia's ultra-high precision CNC machine tool technology may reach the international top level in a short time.

For example, the ultra-high precision CNC machine tools in Wang Bin's Tiangong science and technology precision workshop, in fact, if only take the precision, there is not a big gap with foreign products of the same type, but there is a big gap in other performance, so we need to continue our efforts.

In fact, among these technologies selected by Wang Bin from the system, not many can be selected for him. These technologies are copper based superconducting battery technology, copper based electromagnetic ejection technology, copper based superconducting coil gun technology and copper based superconducting railgun technology.

Wang Bin looked at the only four technologies left in the system, thought about it and excluded the copper based superconducting battery technology, because whether it is electromagnetic ejection technology, coil gun and rail gun technology, these technologies include superconducting battery technology, that is, super large capacity capacitor technology, in addition to their own technology.

Although Wang Bin wants the remaining three technologies in the system, he can only buy one technology with his energy currency, which makes it difficult for him to choose.

At the same time, the prices of these three technologies in the system are not cheap. Among them, the price of superconducting electromagnetic ejection technology is 18 universal currency, superconducting coil gun technology is 16 universal currency, and superconducting rail gun technology is 20 universal currency.

After thinking for a while, Wang Bin chose the copper based superconducting railgun technology with the highest price among the three technologies. However, when Wang Bin just bought the copper based superconducting railgun technology, the prices of the remaining two technologies in the system suddenly changed.

Among them, the price of superconducting ejection technology has been reduced from 18 to 8, while the price of coil gun has been reduced more thoroughly, from 16 to only 6.

Obviously, it can be seen from here that many technologies in superconducting ejection technology, superconducting coil gun technology and superconducting railgun technology are common. For example, the super large capacity superconducting capacitor technology required by superconducting railgun is applied in the other two technologies, or in fact, these three technologies are based on super large capacity capacitor technology.

Although the price of the remaining two technologies has been reduced by more than half since he purchased the copper based superconducting railgun technology, he still can't afford to buy any of them with the remaining energy coins in his hands.

Because Wang Bin now has only less than 10000 energy coins left in his hands.

After purchasing the superconducting ejection technology from the system, Wang Bin withdrew from the system and returned to the store of the science and technology mall. However, he did not return to reality, but quietly thought about the copper based superconducting electromagnetic railgun technology just obtained from the system.

The railgun technology purchased from the system is called railgun technology, but in fact it is not. In fact, it is a complete set of technology, including ultra micro railgun technology that can launch projectiles with a diameter of only 0.1mm, and ultra large caliber railgun technology that can launch projectiles with a caliber of more than 1m or even larger.

Of course, with the current strength of Wang Bin and Tiangong technology, it is impossible to manufacture a super large caliber railgun, because according to the technical instructions given by the system, it is not a simple thing to manufacture such a super large caliber railgun.

First of all, in terms of time, because the energy required for such a super railgun to launch is very amazing, so the super capacitor must be manufactured first.

Although the technical principle of super capacitor is the same as that of small and medium-sized capacitor, and the technical difficulty is not high, its volume is very huge, covering an area of more than 100 meters and a height of tens of meters.

The most important thing is that the entire supercapacitor needs copper-based room temperature superconducting materials to manufacture. It is conceivable how many copper-based superconducting materials are needed. This alone can bankrupt Wang Bin's Tiangong technology.
