But when the economy is a little more affluent, the way people do things is a little different. Although Wang Fang is already developing his unique pure electric propulsion engine, he can't wait to search the market and find a set of gasoline generators for more than 2,000 yuan from Taobao, with a displacement of only 38cc, which is smaller than the engine of his 49cc mini motorcycle.

But this little guy weighing only 12kg can continue to output 850W of electricity for up to 4 hours, and can drive the non-fully wrapped triple jumper with curtains on both sides of Lao Wang for such a long time, which is enough for long-distance running. According to Musk, veteran drivers like to drive for 3 hours and then get out of the car to rest.

At first, Wang Fang also needed to turn on the motor of the three jumpers first, and then turn on the motor of the generator, however, he has now positioned himself as a Geek who plays with motors, and likes to do everything by himself, so he turned this stupid big black and thick device into a fully automatic, which can automatically detect the path, and automatically switch to the charging state when the battery energy is less than 25%, if the three jumpers are driving at this time, the generator is preferred to drive the hub directly.

Honestly, this device is much more cost-effective than using expensive lithium batteries. At present, the price of a large battery of Tesla Model S has reached 50,000 US dollars, even if it does not need such a large capacity, it is not something that a small player like Wang Fang can afford. He has laid the sling-oriented type for his hobbies, and everything that is tall and tall is rejected.

Now he can happily gallop around the city. Of course, it's enough to get on the highway.

After completing this small project, he remembered the three-jumper seller in the countryside of his family, and went to his shop to chat and ask him to appreciate his invention. Amway said to him: "This thing can solve the owner's fear of battery life, and it should be very easy to sell." ”

However, the shopkeeper shook his head: "This generator is more than 2,000? It's too expensive. ”

Wang Bang said angrily: "I didn't earn a penny, are you still too expensive?" ”

Shopkeeper: "Well, you don't make a penny, so what are you trying to do?" ”

Wang Zhan: "...... I'm just verifying the market demand, this is called rapid entrepreneurship, if it's really easy to sell, I can even get a robotic arm to automatically equip it, okay? ”

Shop: "It may be easy to sell in our countryside, but the rural business is not easy to do, the customers are not high, and the after-sales service is very troublesome. I'm a rural person myself, and I don't want to go back to business. ”

Wang Bang: "Are you scaring me?" ”

The shopkeeper laughed: "Why did I scare you?" There's one thing to say. It's no good for me to scare you. For the sake of old customers, I will help you put it in the store and see how the market is selling. You're going to send me one to test. ”

Wang Zhan: "It's no problem to send you, but it's a good buddy to exchange gifts, and you can also give me something." ”

Shopkeeper: "What? ”

Wang Fang: "Your customer's information." ”

Shopkeeper: "This ...... Isn't that okay? ”

Wang Zhan: "What's wrong?" I just did a Unicom phone card was all come to Amway, it can be seen that **This thing is a fart, if you don't give it to me, I can still get it, this gift is gone, do you say yes? ”

The store thought about it, anyway, there was nothing to lose, and Wang Fang was a very right product, so he must not be disgusted by Amway's customers. He said yes, just saying, "There are too many customers, and it will take time." ”

Wang Zhan: "If it's too troublesome, I can help you write a program to download it automatically." ”

Shopkeeper: "Yo, you can also program, it's boring." ”

So, Wang Zhan's job is to go back to programming, using a Gem (software package) in Ruby, called Nokogiri, to write the number of crawling web pages, which is quite troublesome, because Taobao has designed a lot of crawling traps in order to prevent crawlers like "Huihui Shopping Assistant" from picking flowers.

After a long toss, I used the Chrome plug-in to obtain the store's Cookies, which contained the temporary password serial number of the store's Taobao account, so that you could obtain temporary authorization without the need for the store's password, and the whole process should be seen by the store, so as not to cause distrust.

Although I have already bought a ready-made gasoline generator, I still have to carry out my own research, because after all, it is highly customized, and in the future, it may be necessary to combine paragliding power generation equipment with this generator. This is also considered, wind is an unreliable energy source, because it is unstable, easy to encounter windless weather, white clouds in the sky are dull, so what can be done? The combination of two swords is king.

And unless it's the hexahedron sail he's working on, which is used in water, it's not good to travel on land while driving the sail, which takes up too much space and won't be a slightly more reliable way, he thinks.

So in order to be compatible with all kinds of weather, he looked at solar panels. I found that semi-flexible battery panels are already quite cheap, with a price of around 5 or 6 yuan per watt, and it is only 2,000 yuan to buy a piece of covering the body.

Of course, he won't buy it directly, he has his own ideas, and there are two ways to improve the user experience, one is to form a small independent node that can be tilted at an angle according to each tile, which can better absorb light.

There will be a master switch to reverse the angle and direction of the tilt of the entire "Little Sun Farm". He also wants to improve the efficiency of photoelectric conversion, which has high technology, which ordinary civil science can't imagine. The photoelectric effect was first discovered to be excited by ultraviolet light, and the higher the frequency of the photon hitting the photovoltaic panel, the easier it is to excite the electronic transition, that is, to produce an electric current.

The principle of increasing the frequency is the superposition effect of light waves, and the original visible light spectrum can also be superimposed to achieve the increase in frequency, so Wang Fang figured out that Guò invented a special reflector to generate high-frequency photons. The ideal is a nano-level mirror, which can superimpose most of the light, and if it can be mass-produced, the only way to learn from the production process of optical fiber is to add trace impurities to the material and slightly change the refractive index of the material.

Such a production line, it is estimated that there are not tens of millions of people who can't get it, but fortunately, Wang Fang just wants to do it, and the priority is not high, because it is too complicated.

Another uncomplicated design concept is to use cheap reflective film to make a solar sail, when the vehicle is docked, hula pulls up the huge area of the solar sail, magnifying the sunlight dozens of times, cloudy days can become sunny days, sunny days can become deserts, morning glow can become afternoon sun.

Such a huge solar sail must not scorch the photovoltaic panels? Therefore, Wang Fang also wanted to design a membrane that filters out thermal radiation, and it will not generate current anyway, without this thing, ordinary photovoltaic panels cannot withstand dozens of times the light.

In the future, this layer of filter film will penetrate into small particles, which will interfere with the light, and half of it will become infrared rays that do not use lower frequencies, and the other half will be raised to ultraviolet frequencies, which will definitely be a story for another time.

Wang Fang saw some ordinary mirror reflections on the Internet, a mirror as big as a photovoltaic panel can only increase the power by about 10%, it's too low, I don't know what kind of surface my mirror sail has, I'm looking forward to it.

He continued to be creative here, and he also told Ouyang Fen about it, and Ouyang Fen was coquettish: "Can you be reliable?" I'm not done yet, I'm thinking too much. How can this be done? Hey, I'm a volunteer, unpaid! ”

Wang Bang said dejectedly: "I'm sorry, I just can't help but say, you take your time, no one forces you." ”

Now Wang Zhan doesn't dare to mess with her, and finally found a free high-tech volunteer, don't let her run away, anyway, the 18,000 is worth the cost, one-time.

Therefore, when she suddenly didn't know why she said this, Wang Zhan was very nervous. She said, "What's the use of making this sail?" It is impossible for people to use sails as power anymore, because they are too slow, and even if your invention greatly increases the speed, it is impossible to be too fast to keep up with the needs of the boat bosses. ”

Wang Bang immediately used his brain and said: "It can be used for sightseeing, a strange sailing ship must be hugely attractive to tourists, do you know?" There are still people who build 250-meter-long galleons, which are luxury cruise ships for local tyrants. ”

Ouyang Fen shook his head: "It still feels unreliable." ”

Wang Bang said again: "Okay, if it's too difficult, you can develop ordinary tourists in China, the engine will destroy the peace of the attraction, we sell our artifact that doesn't make noise to the administrator, and there will definitely be an administrator who has a pursuit to approve it." It's really not good, we develop it ourselves, build a small boat to operate, and it's OK to be able to seat a dozen people.

A person who earns 1,000 yuan can earn more than 10,000 yuan a day, is it better than a part-time job? What is Marketing? Marketing is to have a unique selling point, our sailboat is unique in the world, this gimmick can not attract a group of 27% of literary and artistic young people chasing novelty? ”

Sure enough, the leader must be able to flicker, after Wang Zhan's unreliable flickering, Ouyang Fen re-energized, but also said: "When the time comes, you will be the captain, and I will be the first mate, hehe, we will also have a good time." ”

Wang Fang hurriedly agreed with a smile: "We can still hype up topics like 'the most beautiful first mate in history'." Guaranteed to come like a cloud. Maybe you'll have to wait in line to buy tickets. ”

Ouyang Fen loved to hear this, and couldn't help but be coaxed with joy.

In order to enhance the credibility of his words, Wang Fang also pretended to search for the most beautiful tourist routes on the Internet, and deliberately shared them with the circle of friends, with sensational language such as "I really want to take a little white sail to visit here".

I didn't expect to be attracted by my lies, the hexahedral sail is indeed very windy, isn't it? Pull from the six wind directions together, and you can't pull the wind if you don't want to.

Back then, the guy named Chase, who worked hard, was born and died all his life to get his own whaling ship, Wang Bang wanted to investigate whether his 1 million was enough to build and operate a ship, and it was estimated that it was enough to choke.
