Since we talked about the topic of tallness, Wang Fang explained to Begonia the model that was on his table by the way.

"What is this? Guess. Wang Bang asked.

Begonia: "It's like a sailboat, but why is it reflective and blinding other people's eyes?" ”

Wang Bang: "Yes, this is the next step of our escapement technology, called mirror sail, we now use paragliders to obtain wind energy, mainly to obtain high-energy wind power in the sky, but when it rains, the food will be closed, and the paraglider will become very heavy after being permeable." So the current plan is flawed, and we are thinking of another solution.

Israel has been in a confrontation with the Arabs for a long time, and they are most afraid that energy will be controlled by the enemy, so they have been vigorously promoting alternative energy sources, and there are millions of civilian solar panels on their residential buildings, and I am afraid that the destruction of power lines in the event of a war will have little impact on the whole of Israel.

One of them, ZenithSolar, came up with the idea of using mirrors to concentrate light in order to reduce the use of polysilicon. Their mirrors are pot-shaped, and the power generation is increased by a full 5 times. Even better than I had thought before, they also used water to cool the heat energy that was too concentrated.

Hot water can be provided to residents or to factories with high energy consumption, and according to them, if the use of heat energy is included, the overall energy efficiency is 1,000 times higher than that of traditional flat panel photovoltaic panels. It seems ridiculous. But this line of thinking is fine. ”

Begonia nodded: "Well, 1000 times...... This jump is too big, I'm afraid it's not easy to achieve. So, a mirror sail is something like that too? ”

Wang Zhan: "Correct solution." But we can't be exactly like them, so how competitive are we? After all, the credibility of Israeli technology companies is much stronger than that of our domestic products, so the mirror sail not only has their similar effect of collecting light beams and heat energy, but also the sail. You see, how strong are those sailing galleons?

We put treadmill-like equipment under the sailboat, and when the wind comes, we can move with the treadmill and generate electricity. So, we're doing it all three, it's light, heat, and wind. If Zenith can generate 5 times more electricity, we may be 7 or 8 times, if the overall energy efficiency is 1000 times, we may be 1500 times, in short, it is right to kill this strong opponent in seconds. ”

Begonia was excited, but she also asked, "Does Musk know about this technology?" Why didn't his SolarCity adopt a similar scheme? At least 5 times more power generation capacity, he should adopt it. I saw a large blue field on the roof of his GigaFactory, full of flat photovoltaic panels. ”

Wang Zhan: "He may or may not know, if he knows and doesn't adopt it, it may be ...... Because power generation is easy and storage is difficult? Now it seems that there are a lot of solar panels on the residential buildings, but they don't need it when they go to work during the day, and when they go home at night, the sun sets again. ”

Begonia: "Wouldn't it be OK to buy a few more batteries?" ”

Wang Fang: "Lithium batteries are very expensive, and Tesla's kind of household battery requires $3,000 for entry-level. By the way, Zenith's civilian small model costs $30,000 a set. Foreigners' money is really good to make. ”

Begonia: "So the future of the mirror sail is not necessarily so promising, what is the cheapest solution to store electricity now?" ”

Wang Zhan: "The mature solution that is now being put into large-scale use is to build dams, pump water up when the grid is idle, and open the sluice gates to release water to generate electricity when the pressure is high. Obviously dams aren't cheap, and there are some small ideas, such as the invention of a British professor using an 'energy bag' to store energy, and a high-strength inflatable bag to store compressed air...... Or compressed water? I don't remember exactly.

Anyway, the essence of this solution is that the energy bag needs to be placed on the seabed, where the water pressure is high, which can balance the huge pressure inside. This needs to be by the sea, the scalability is not so good, of course the British can be surrounded by the sea, we can't, the Yellow Sea or something is also a shoal.

If there's anything else...... Using a mirror to collect heat energy and heat the salt to a molten state, it can continue to heat up all night, which is not cheap. Because the larger the container for molten salt, the better, in order to keep warm, geologists used to measure the temperature of the earth to determine the age of the earth. ”

Begonia: "Hmm...... That's the world's problem. It doesn't matter, I see, as long as you surpass that Israeli company, you can dominate, at least Escape Technology deserves to be the star company of new energy, right? ”

Wang Fang: "Yes, but I'm also going to try a unique solution - using hydrogen to store energy. When the grid is idle, it is used to electrolyze water, all in hydrogen balloons, which is different from most current solutions. The storage safety of hydrogen is now in question. So, I put them in hydrogen balloons and put them high in the air, even if they are fried, it is nothing, and the hydrogen is so spicy that it will not remain when fried.

Hydrogen itself is energy, and our huge hydrogen balloons can't be wasted, I don't know if you've seen the hydrogen balloons that can generate electricity in our real room? I decided to take a strict approach to the use of light balloons to generate electricity. Eh, it seems that the way to put the treadmill under the sailboat I just mentioned is okay, because ...... Using a pulley to block horizontally, you can turn the lifting force into lateral traction, which is no different from a sailboat, and you can happily pull the treadmill to turn.

Not bad, that's a good idea. Boss Wang was excited by the idea he had just had.

Begonia: "The sense of déjà vu of a perpetual motion machine, are you sure that it does not violate the laws of physics?" ”

Wang Zhan: "This ...... I don't think I can understand why I was the first to think of it, but a small hydrogen balloon can fly tens of kilometers high, and it is not very in line with the energy law of coming out to mix, right? It can be seen that the clever design of Tong guò can make energy very cheap. ”

Begonia proposed a mindset experiment that stunned Wang: "What if your roller skating is reliable?" Ahem, let me ask you, why do you need hydrogen balloons? Isn't gravity always there? If you make a pulley on the table, hang an iron ball, and use the iron ball to turn into a downward force, pulling the treadmill to turn, isn't that the same? Isn't it hilarious? ”

After thinking about it for a long time, Wang Fang clarified his clue, and was almost dizzy by this little girl's skin. He said: "I have figured it out, whether it is the upward force or the gravitational force, it does not do work when it is stationary, so it is impossible for the hydrogen balloon to stand still, maybe we can use a rope to hold the hydrogen balloon, and when it reaches a height of several thousand meters, we will use some kind of device to pump the air into the hydrogen balloon, and then we can use a relatively small force to pull the hydrogen balloon down."

Hanging a large iron ball obviously does not have this advantage, so it is still a hydrogen balloon that is king. We can also connect two hydrogen balloons together, when one balloon rises to the limit, then use the second balloon to generate electricity, and the power supply No. 1 ball inflats and sinks, and at the same time pulls it down, so that once it goes up, the stored hydrogen can directly generate electricity.

As complicated as it sounds, God forbid we can make it. ”

When he turned around, he must ask the personnel department what is the origin of this little girl, it seems to be very powerful.

What he didn't know was that Xiao Niangpi also felt that the old Wang was very powerful, and when he went home, he saw the old brother and said: "Brother, I reported to the Golden Chain Finance today and saw Mr. Wang, this guy seems to be a talent, you don't beat him to death with a stick, maybe it is better to keep it to help you make money." ”

Qiu Zeyu: "You can also see it?" Of course, it's a talent, otherwise why did you say that you moved Mr. Duan to engage in gold chains when you first met? That's a big bet on your future. ”

Xiao Niangpi: "Wang always does big things, I have a preliminary understanding, he is going to recruit the first step to recruit and develop the big bull, can create a zào programming language of the bull, first develop a DSL, that is, a domain-specific language, specially used to write blockchain programs of the language, I don't understand the specifics, but I can also see that he is very serious about making a big deal, not the kind of person who cheats money and runs away." ”

She also excitedly posted photos about the washing machine that was invented there to solve the problem of mixed laundry, and she joined a team that made shoes as a co-founder.

Speaking of the back, Qiu Zeyu was unhappy: "What? You're going to live in a place like this? No, it's not safe. ”

Begonia: "Safety! This is a well-known innovation industrial park in Hot City, who dares to make trouble here? I'll just stay for a few days, the capsule, have you ever lived? Hehe, it's a girl-only room, it's okay. Besides, I've also practiced taekwondo, and a few strong men can't get close. ”

Qiu Zeyu burst into laughter: "Forget it, your fist and embroidered legs, haven't you heard of ten times with one force?" Punch the master to death, have you ever heard of it? ”

Begonia snorted: "Do you want to taste my beautiful roundhouse kick?" ”

Qiu Zeyu laughed, but the next sentence from the girl surprised him: "Hey, I still see ...... in the company Your fiancée. ”

Qiu Zeyu's heart jumped: "What? Tang Xia! What is she doing there? ”

Begonia: "She just talked to Wang Bang for a few minutes, I want to listen secretly, but the sound insulation effect of the office door is too good, and when I came out, I saw her face, could it be that they had a great relationship before?" This is to sue the king to fry her to marry you, so ...... By the way, Wang Zhan was not very affectionate later. I see. , no, I thought Wang Fang was a talent, but I didn't expect it to be such a talent, and it could attract Charlotte? ”

Qiu Zeyu was already itching with hatred, and snorted coldly.

Begonia: "Look, it's good for me to go undercover, right?" Don't worry, I'll help you take a good look at your fiancée, my brother is so handsome, isn't it very shameless to lose to an old king who is not good-looking? ”
