Until Ding Chen's entry into the orbital space station, wind power was still a relatively popular concept. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Among the few clean energy projects that can be put into practical use, wind power is also the youngest one.

At that time, the public opinion was quite optimistic about the prospects of new energy, especially after the breakthrough of semiconductor energy storage materials, experts from all walks of life on the media network said that traditional chemical energy is about to be eliminated, at least in the future, the electricity used by everyone will come from clean energy. The newly designed smart community even claims to be self-sufficient.

Some have even announced that they have developed an air energy conversion device that can allow individual households to say goodbye to their electricity bills. Ding Chen felt that at least this slogan could be realized, as long as the family didn't care about replacing the electricity bill with other consumables.

In fact, there is no need in the industry, even Ding Chen knows the development and utilization of energy, the conversion situation is never the most important, the real factor that determines whether it can be practical is the cost, and there is no technical means to promote, as long as there are cheaper alternatives, no matter how advanced the technology can only stay on the booth.

It's just that the hot speculation of new energy is equivalent to a feast of money for the industry, everyone is happy to make a fortune in a muffled voice, and the gods who do not add fuel to the fire must be regarded as the orderly and good camp.

From the point of view of cheapness, the advantages of wind power are actually not high. Although wind energy is a product of nature and does not cost money, it costs money to convert this free energy into a form that can be exchanged for money.

Generally speaking, the wind is always very capricious, and the strength of the wind energy can vary greatly at different times of the year in the same place. This is a major headache for technicians who want to harness wind energy.

Because it is obvious that the conversion output curve of wind power energy type changes with the input curve, the power supply party cannot require the electricity customer to use more electricity when the wind is strong, and less or no electricity when the wind is small.

In order to ensure the stability of the input power, it is necessary to find a way to make up for this shortcoming. Therefore, the technical difficulty of wind power is actually mainly in the substation components. Until the advent of semiconductor regulators with a wide voltage range, wind power was destined to be used only as an auxiliary energy source.

In fact, in Ding Chen's memory, the large-scale launch of wind power in China at that time certainly had the purpose of preserving technology and training teams in advance in order to seize the market, but another main reason was that new energy technology could be subsidized by the state, which was equivalent to diversifying the risk. If this reason is removed and all wind power manufacturers are required to be responsible for their own profits and losses, I am afraid that most wind power plants will immediately abandon their work.

It was for this reason that when Ding Chen heard that wind power was used here in the apartment, he didn't have any special feelings. New energy usually means new technologies and new equipment, and new technologies and new equipment are usually related to semiconductors, most of these components are maintenance-free replacement parts, even if you know where it is broken, Ding Chen can not find new parts to replace.

Of course, the most important point is that Ding Chen knows very little about wind power, and is far less in-depth than he knows about traditional power generation methods.

However, wind power also has something that interests him, but this thing is also a mechanical energy conversion of electrical energy, not as high as the integration of photovoltaic power generation, and the rest of the solar panels will not do anything if they are broken. Wind power still has something useful left anyway. That's why he was in a hurry to go into the mountains to see the goods.

So now looking at the wind power towers that appeared in the mountains in the distance, Ding Chen finally breathed a sigh of relief. Of course, he wouldn't mind walking for a few more days, but if he wanted to transport the things back here, the length of the journey was very important, no matter how good Ding Chen's physical strength was, he couldn't carry out a continuous weight-bearing trek.

There is a saying called "running and breaking your leg when you look at the mountains", which means that in the mountains, you often can't reach the place not far from you, and you are likely to break your leg if you take a detour. Ding Chen: This is the situation they are encountering now.

After a long period of time, the road left behind by the construction of the power plant was completely unrecognizable, and the three of them had to walk through the dense forest, wading through a stream five or six meters wide in between, to reach the foot of the mountain where the wind farm is located.

There is a cement road covered with thick moss, if Ding Chen hadn't found that there were no trees in the places where this road passed, I am afraid that the three of them would not have been able to find that the bottom of it was actually cement.

After coming down from the mountain, Ding Chen began to organize the formation, asking Zheng Yu and Rogge to follow him at a distance of five to six meters while remaining vigilant. Normally, such a low-target civilian facility would not bother to set up a warning net, but Ding Chen didn't know what happened in the world during the time he turned into a popsicle, and it was not incomprehensible if someone was so mad that they laid mines near civilian facilities.

It is precisely because of this vigilance that Ding Chen will notice the difference in Yongdao.

Zheng Yu and Rogge were relieved to see Ding Chen scrape off the dirt and plants on the road with his saber, revealing the cement slab underneath, and Rogge asked strangely, "Do they rely on this road when they transport things up?" ”

Even if Rogge had never seen a wind turbine before, but he had just seen what the target looked like on another mountain, and the towers tens of meters high were definitely behemoths, so Rogge wondered how they were transported into the mountain.

Ding Chen was also a little puzzled, at first, he judged that there should be a road or railway to reach here, but he was unlucky not to encounter it. But now it seems that the road was probably not built at all.

"Probably by air." Ding Chen explained: "If the cost of building the road is too high, it may be lifted by helicopter. ”

In fact, in Ding Chen's view, helicopter lifting has another advantage, that is, it can be lifted directly as a whole, and even the work of on-site assembly is saved.

The other two looked at each other, and Rogge asked, "What is air freight?" ”

"It's flying from the sky." Ding Chen explained casually, his gaze fell on a trace on the road, and he frowned slightly.

Rogge and Zheng Yu looked at each other, and they both felt that it was unbelievable that such a big thing could fly.

Ding Chen didn't mean to continue to explain, he raised his hand and made a gesture, and said in a low voice: "This road has been walked. ”

The other two immediately threw their feelings for Feitian to Java's side and became nervous together.

Rogge reached out and grabbed the tail of an arrow on the quiver behind his back, looked around and said, "How long?" ”

"It won't be long." Ding Chen carefully looked at the traces on the ground, looked at the mountain again, and said, "I don't know how fast the plants here grow, but it shouldn't be more than a week." ”

After speaking, he told the two people: "Get a little closer to me, and you will step on me wherever I step." ”

Rogge was taken aback, his heart became even more nervous, and he subconsciously lowered his voice and asked, "Is it so dangerous?" ”

Ding Chen snorted. This place has been completely separated from the human gathering area, and those who can survive in this kind of place are strong, even if they don't plan to set traps to deal with people, it is not difficult to get two traps by the way when hunting, and when the time comes, they can only admit that they have suffered losses.

It was only in this way that the speed of the three men dropped a lot, and it was not until the sun turned west and the woods began to become dark that they came to a small two-story building.

Holding a bow in his left hand and an arrow in his right hand, Rogge put it on the bowstring, maintaining a posture that he could attack at any time, looked at the small building in front of him, and said in surprise: "How can this be." ”

No wonder she was surprised, even Ding Chen, who had seen the natural world reclaim human territory many times, felt that the scene in front of her was very surprising.

The small building was surrounded by trees of all sizes, and from their position it was clear that the branches of a large tree were directly passing through the walls of the second floor and protruding into the house.

But this was not the most surprising part, they also saw that in the corner where the first and second floors intersected, a small tree was stubbornly sticking its head out of the crack in the wall, waving its longing towards the sky.

Even the trees have grown into the building, not to mention the various plants that are crawling on the building, and the green feather that covers the front steps of the door is simply the most normal decoration.

"Can you still get in here?" Zheng Yu asked suspiciously.

Ding Chen stared at the green feather on the steps in front of the building, and said in a low voice, "There are people in the building." ”
