Boss Wu was still unsatisfied, and said: "According to what you say, it seems that wind energy can also make a big empire." ”

Wang Zhan: "Yes, it's not just a windmill empire like the Netherlands, if this thing is played well, it will have to be played now." At present, the height of mainstream wind turbines is 100 meters, and the higher it is, the more difficult it is to build, and many startups are studying how to subversively increase the altitude of the generator, because the higher the altitude, the higher the wind energy density.

There are about 50 companies around the world doing research, including one that Google acquired a few years ago called MakaniPower. It works much like the previous GoogleWind drone, a quadcopter rotor, but the four axes are relatively close to each other, and can have a horizontal position like a fixed-wing aircraft, and the specification of the test aircraft is 600 kilowatts, and it is now 140 to 300 meters at an altitude.

This is equivalent to a 140-meter-high blade, however, there are many problems, at present, Makani's solution requires the plane to pull the wire in a circle, and the radius is also 140 meters, which is still quite a considerable footprint. I believe that the intelligent control system will definitely be done, and people can even make AlphaGo, and the intelligent circle is not like a thing.

The problem of this floor space is a hard injury. If you're not careful, the two planes can also collide together. And it's not as difficult as it is to deal with bad weather.

There is also a player called SkyWindpower, who uses a pure quadcopter rotorcraft and can hover, so there is no problem of turning in circles, and it can partially solve the problem of large footprint, but this requires the generator to be placed directly on the plane, which is really big enough.

All and there is a third type of player, they use helium airships to make airplanes, which can carry a considerable weight of generators into the sky, I forget what the name of the company is, the abbreviation of the product is very easy to remember, it is called BAT. I feel that helium airships are expensive to build, so they may have a hard time in terms of cost.

In terms of cost, the advantage is the use of a glider, a flight tool between a kite and a parachute, whose trajectory is not circular, but figure-eight, which switches between windward and speed, turning the figure-eight power into the force that pulls the turbine on the ground. Actually, I'm more optimistic about this. ”

Boss Wu: "I know when you say glider, because I have been to play, it is very enjoyable, much more enjoyable than looking at the earth from an airplane, a little acceleration can make a person fly, and the power is indeed quite high." ”

Wang Fang: "One manufacturer estimates that their glider-sized generator can generate 50 kilowatts of electricity for 30 homes. ”

Boss Wu: "50 kilowatts, that is, 50 degrees, the retail price of one kilowatt-hour of electricity is 5 cents, and at the end of the day, it is 25 * 24 = 625-24, about 600 yuan." A glider is estimated to be 6000 can be taken, anyway, it is not for people, domestic goods are fine. If you can invent this kind of generator and sell it to rural folks, wow, you can get back to your roots in 10 days. ”

Wang Fang also smiled: "Counting the generator, it may take 20 days to pay back, how about it?" Mr. Wu, why don't you join the Wind Energy Revolution Entrepreneurship Corps? ”

Boss Wu was eager to try, but he didn't have much confidence: "This is high-tech, is it reliable?" Google is doing it. ”

Wang Bang patted his chest and said, "Relying on creativity, this thing is irregular, anyone can do it." Don't be frightened by these so-called high IQ comparisons, the Yankees spent millions of dollars to develop space pens, only to find out that people use pencils when they communicate with the Russians! The Yankees were watts at the time. ”

Boss Wu laughed and was really a little moved, and said, "Then I have to ask you to be a partner." I feel like you've got a brain. ”

"I don't have the funds unless I can sell the website," Wang said. ”

Boss Wu: "It doesn't matter, technology is a shareholder. What should we do? Flying wings? It seems that automatic control is the key. ”

Wang Zhan: "There is a ready-made automatic control plan, hehe, I have already said it just now, you should think about it." ”

Boss Wu was inexplicable: "What? Can't remember. ”

Wang Zhan: "Alas, could it be that I really have a brain talent? Such a simple thing...... We have already said when we crossed YY just now, clockwork and clocks. The escapement mechanism of a mechanical watch can even keep time, but I am afraid that it cannot be controlled automatically? Isn't the reversal of the clockwork system the power generation? And this system solves the problem that Google Makani has too much footprint.

Imagine that the pendulum of the mechanical clock, swinging left and right, whether it is an airplane or a glider, only needs a very small shaking, which is basically equivalent to not moving, and the generators on the ground can be almost lined up, as many as you want, and the rural villagers can also operate it. ”

Boss Wu: "! Good idea, I thought it was pure YY just now, but I didn't expect it to be used so quickly on the idea of starting a business. It seems that we have to have a watchmaker on our team. Wow, that's a good idea, you should go get a patent. Really, maybe you can sell it to Google, and it's not bad for money. ”

Wang Bang coughed dryly: "It's still the same old saying, Lao Tzu has no money, and there is no money to apply for a patent, if Boss Wu is optimistic about this, you can fund it, in case this patent is applied, I will give you priority in the future." ”

Boss Wu: "We set up a company, the company helps you apply, and then you use patents to buy shares, it looks like we are a high-tech company, I am responsible for finding a patent lawyer, we do spam, I really haven't contacted a patent lawyer, I have friends with other lawyers." ”

Wang Zhan was happy: "Really fake? I relied on Boss Wu to turn over my salted fish. We're going to be inventors too. ”

Boss Wu laughed: "I see that you have the potential to be a late bloomer." You're like a name, I'm really going to register a company. ”

Wang Bang pondered for a while and said, "Escapement technology? ”

Boss Wu: "Is it really good?" I feel like seven captures of Meng Huo. ”

Wang Bang laughed: "Isn't this good? Zhuge Liang can capture seven verticals. On behalf of our company, we are wise and close to demons. ”

Boss Wu: "This seems to be Lu Xun's words to slander our Wuhou, but you used it as a compliment." ”

Of course, although Boss Wu looks very interested, he doesn't know if the execution will work, after all, he is still a new friend he just met, Boss Wu returned to his nest to find a lawyer, and Wang Fang also sent his mini motorcycle to Guò Logistics back to Recheng, and took the train back to his home.

On the train, Wang Fang was very interested in buying a book on sailing ships to study, and also bought a model of a whaling ship.

On the weekend, Wang Zhan took his whaling ship to give a lesson to the two middle school students, explaining how to control the three-masted sailing ship, and he himself studied it for a long time before he was sure to explain it in simple terms.

Many people, including Wang Zhan, thought that the advance of the sailboat depended on the thrust of one side wind, but in fact, it was a big mistake. What you can't imagine is that the wings of sailboats, wind turbines and airplanes are all based on the same principle, using the difference in surface area between two surfaces to create a difference in wind speed, which in turn produces a difference in air density, and it is the difference in air density that produces the final thrust.

A spinnaker is complicated enough, because to calculate the angle between thrust and drag, three sails really can't be understood casually, it involves how to borrow force in the face of a headwind.

These three sails can be understood as a mechanical structure that can get power from almost any angle. If you are not careful in the learning process, you will be confused, and both students will listen attentively, because this model ship is very beautiful.

When they understood, they were all very happy, and Lianxing also noticed that the word "Chase" was engraved on the ship model, and asked: "This is the Chase, is the name chosen by the teacher himself?" Does it mean anything? ”

The mothers of the two students were eating snacks on the side, and Wang Fang didn't dare to tell the truth. It turns out that the name of this prank really has a big story, which is used to satisfy Mr. Wang's bad taste.

There was a whaling ship called the Essex, which hunted whales all day long, but was overturned by sperm whales, and more than 20 sailors fluttered and all fell into the water, but fortunately, they had three lifeboats. The closest place to them was Marquesas Island, but when they heard that there were cannibals on the island, the crew did not dare to go to the island, so they chose a path of no return - crossing the South Pacific Ocean and wanting to go to Chile.

It turned out that after 60 days of drifting, a small island was discovered, a very small island, and the seabirds on it were eaten up by the sailors in a week, and the three timid people no longer dared to leave the island with fresh water, and the rest of the crew continued on the road, this time it was even worse, after 90 days of drifting, some people starved to death.

Then, when the others saw the corpses of their companions, a terrible thought was born in their minds - to become cannibals. One of the few surviving fellows was a first mate named Chase, who also published a book called "The Whaling Ship Essex Shipwreck".

This time, the shipwreck led to a difficult ethical trial, and whether or not it was possible to consume humans under extreme circumstances has sparked an unprecedented moral controversy. There was also a buddy who ate his cousin, and his relatives never got along with him from then on.

Wang Zhan was very emotional about the survival instinct of human beings, and especially admired the first mate Chase who also wrote the logbook, and he could still keep his sanity in that situation, and some of the crew members were crazy when they survived, and they only knew how to hold the bones that had eaten the flesh when they were rescued.

The surviving buddies were more or less insane, and Chase was in the best shape, just storing food in his attic forever, otherwise he wouldn't be at ease. In Wang Zhan's eyes, Chase is not only not the object of moral judgment, but a tenacious and courageous hero, who has a fight with the ancient Chinese people "Yi Zi and Eat".

These stories are too terrifying, if his students were boys, he would have shared them a long time ago, pity the stars and invite the moon, such cute little cuties, I really can't bear to scare them. Besides, if their mother Tress finds out about this, hehe, I'm afraid I won't be able to keep my job.

Therefore, hearing the question of the mercy star, Mr. Wang smiled mysteriously and didn't say anything.
