At present, the fields that are most likely to produce results are composite materials, power grids, electric motors and generators.

Because they generally use the rope manufacturing method, weaving together multiple 2-nanometer diameter 16-meter-long single-walled carbon nanotubes like ropes, and then forming a thicker wire.

Or, like the British scientists in the past, they could combine single-walled carbon nanotubes with copper wires to eventually create copper/carbon nanotube superconductors.

This will greatly improve the performance of traditional copper wires and reduce power transmission losses.

As for which of these two forms is better or worse, we can only say that each has its own advantages and disadvantages.

Wires composed entirely of single-walled carbon nanotubes have the best performance, which is equivalent to the full performance of 5G networks. They are true super wires. The disadvantage is that the cost is very high.

After all, the diameter of a single-walled carbon nanotube is only 2 nanometers, while the diameter of a human hair is 6 nanometers.

How big is a strand of hair?

negligible!

At this time, we want to twist these single-walled carbon nanotubes into a single-walled carbon nanotube wire in the same way as weaving a rope.

The number of carbon nanotubes required is enough to make one's scalp tingle, so although the superconducting wires made entirely of single-walled carbon nanotubes have good performance, the cost is too high and it is difficult to popularize them on a large scale.

The copper/carbon nanotube superconductor combines single-walled carbon nanotubes with copper wires.

Although its performance is not as good as that of superconductors composed entirely of single-walled carbon nanotubes, its advantage is that it is cheap.

Adding a certain proportion of single-walled carbon nanotubes into regular copper wires will definitely greatly improve the performance of the copper wires and turn them into super conductors.

The higher the proportion of single-walled carbon nanotubes inserted into the copper wire, the better the performance of the copper wire will be, so the performance of copper/carbon nanotube superconductors cannot be easily quantified.

But even so, even if only 0.1% of single-walled carbon nanotubes are added, the performance improvement of copper wire is still considerable, enough to be called a super conductor.

Of course, it is still too far to talk about that, because let alone adding 0.1% of single-walled carbon nanotubes, even adding 0.01% of single-walled carbon nanotubes is impossible.

Because the knowledge instilled by the Xingtu seven-axis linkage machining center does not include how to mass-produce this single-walled carbon nanotube with a diameter of 2 nanometers and a length of 16 meters.

It just gives you a method for producing a single-walled carbon nanotube with a diameter of 2 nanometers and a length of up to 16 meters.

The goal is to use this method to mass-produce single-walled carbon nanotubes that are 2 nanometers in diameter and 16 meters long.

We still need to find a way to create a special production equipment that can mass-produce single-walled carbon nanotubes.

So Lin Feng just thought about it for a moment, and then decided that this special equipment that can mass-produce single-walled carbon nanotubes must be manufactured.

Because the role of this single-walled carbon nanotube is so great, it is so great that once all industries have it, they can achieve huge breakthroughs.

Let’s not talk about anything else, let’s just talk about the power grid area.

If this copper/single-walled carbon nanotube wire can really be created and used in the power grid, it can greatly reduce the loss of power transmission.

According to statistics from relevant agencies, the power loss rate of the power grid is generally between 8% and 12%. The reason why the loss rate is so high is that the longer the wire, the higher the resistance.

The only way to solve this problem is to increase the voltage transmitted by the power grid. Therefore, countries around the world are developing ultra-high voltage transmission technology.

Among them, Daxia's ultra-high voltage transmission technology is undoubtedly at the forefront of the world after years of heavy investment and research and development.

Therefore, in the previous life's "Great Power Heavy Industry" series, there was a special program explaining Daxia's ultra-high voltage transmission technology. Of course, even with ultra-high voltage transmission technology, it cannot completely solve the problem of excessive power grid loss rate, but can only significantly reduce it.

After all, the voltage of the 220V and 380V power grids in urban streets in towns and cities is within a constant range, and there is no way to further increase the voltage.

Therefore, this part alone makes it impossible to completely avoid the problem of excessive power loss rate in the power grid.

But now there is a solution, and that solution is to rely on copper/single-walled carbon nanotube superconductors, which will greatly reduce the energy loss of the power grid.

This reduction in grid energy loss is equivalent to gaining that part of electricity for free, and the economic benefits are very large.

After all, this 8% to 12% power loss rate in the power grid occurs every moment. It is hard to imagine how much power is lost in the national power grid in a year.

How much coal resources will be consumed and how many hydropower stations will be built to recover the lost electricity?
Therefore, in the field of power grid alone, special production equipment for large-scale mass production of single-walled carbon nanotubes must be developed.

Of course, in addition to playing a huge role in the power grid field, single-walled carbon nanotubes also play a considerable role in the field of composite materials.

Take wind turbines as an example. The longer the blades and the larger the blade area, the higher the power generation efficiency will be. After all, it can absorb more wind power.

The reason why the blade area of ​​large and super-large wind turbines now and in the past appears so slender.

The reason is that the blade material of the wind turbine cannot withstand the huge twisting force caused by such a large blade area.

In addition, the longer the blades of a wind turbine are, the higher the weight of the blades will be, which is difficult to solve with current materials.

Therefore, although wind turbines have been invented for hundreds of years, wind turbines with blades over 100 meters long have not yet been invented.

After all, scientists around the world can see the benefits of wind turbines with blades that are 100 meters long.

It is impossible for them not to know the huge benefits when the fan blades reach a length of 100 meters. The reason is still the material problem.

But now with single-walled carbon nanotubes, the material problem is no longer a problem. After all, single-walled carbon nanotubes are a super material that can be used to make a "space elevator."

Using it together with other materials to make a composite material can easily withstand the weight of a 100-meter-long fan blade and the twisting force exerted on the fan blade by external wind pressure.

After that, with the blade length of hundreds of meters and the wider blade area, the power generation efficiency of such a wind turbine is definitely very high.

It can be said that if such a wind turbine can really be developed, it is possible to directly reduce the proportion of thermal power generation from more than 70% to less than 15%!

After all, thermal power generation causes serious environmental pollution.

It releases a large amount of harmful substances every moment, produces dust, carbon dioxide, sulfur dioxide, etc. every moment, and produces a greenhouse effect.

Daxia has a vast territory and there is no shortage of places to install super-large 100-meter-class wind turbines. Whether in the northwest or the vast coastal areas, those areas have never lacked free wind.

Therefore, if such a 10-meter-class super-giant wind turbine can really be developed and the cost is controllable, the cost can be recovered within years.

That will definitely gain huge support, and eventually usher in a great era of infrastructure construction, thus completely replacing the model that mainly relies on thermal power generation in just a few years.

After all, you just need to build a wind turbine there, and then the wind blowing all the time can provide you with a steady supply of electricity.

The economic and environmental benefits brought about by this are visible to the naked eye. How can Daxia not strongly support it at this time? (End of this chapter)
