Chapter 104 (1/2)

In terms of non-metallic superconducting technology, there are problems in production cost and equipment.

Therefore, Wang Bin prefers metal room temperature superconducting materials, especially those with common metal materials as the core, such as copper and iron. Magnesium, aluminum, etc.

In entering the science and technology mall system, Wang Bin directly ignored the non-metallic superconducting material technology, chose the normal temperature metal superconducting technology, and selected it among the sub projects.

There are also many metal superconducting material technologies, such as iron-based superconducting material technology, magnesium based superconducting material, copper based superconducting material, thallium based superconducting material, mercury based superconducting material and so on.

However, Wang Bin directly ignores those superconducting technologies with rare materials or metals as the main materials, because even if Wang Bin buys these technologies, they are still some chicken ribs for his world.

Coupled with the use of scarce metal materials as the main materials, the production cost will be very high and the materials will be very difficult to obtain. Even if the basic materials can be purchased from the system in the future, the price must not be cheap and very uneconomical, so these Wang Bin basically do not consider.

Soon he found the technology of iron-based and copper-based superconducting materials.

Of course, even for iron-based or copper-based superconducting material technology, the materials used are not only metals such as iron and copper, but also many other materials. However, compared with the previous superconducting materials based on scarce materials, these superconducting materials are only used in a small amount.

However, compared with those superconducting material technologies based on scarce materials, superconducting material technologies based on common metals are obviously much higher in price.

For example, the primary superconducting material technology with metal niobium as the main material sells for only 30000 energy coins in the mall.

However, the price of primary copper-based superconducting material technology with copper as the main material in the mall is as high as 45000 energy coins, while that of iron-based materials is more than 50000.

Then Wang Bin thought about it and directly purchased copper based room temperature superconducting material technology based on copper from the mall at the price of 45000 energy coins.

As for iron-based room temperature superconducting material technology, these energy coins in Wang Bin's hand can not be purchased.

Just when Wang Bin bought the copper based superconducting material technology, Wang Bin's system rang again; ”Dear host, congratulations. You have completed all the requirements for the promotion of the science and technology mall. Would you like to promote the science and technology mall?”

After listening to the words of the system, Wang Bin's heart was finally greatly relieved. In fact, the reason why Wang Bin was so eager to buy technology is actually for the promotion of the system.

After all, at the first level, Wang Bin can only buy primary material technology in the system.

As for other technologies. He can only deceive the technology he wants from his customers, and even if he deceives the technology, he must realize these technologies by himself, and can't put the technology directly into his mind.

However, after reaching the second level, the technology Wang Bin can buy in the system is not just material technology.

At the second level, Wang Bin can not only continue to buy materials and technologies in the system, but also buy various raw materials that can be found in nature. Most importantly, at the second level, Wang Bin can use the system to buy some real scientific and technological products.

So he immediately opened the system and inquired about what he could buy. He found that the price of these raw materials in the system was almost the same as that in reality.

However, it is extremely uneconomical to use energy coins to buy some common materials that are easy to buy in reality, such as steel.

However, if you use energy coins to buy those scarce materials in the mall, it will be different. The first is the scarce materials, although there are very few in the real world.
