GravityLight. As the name suggests, it generates electricity from gravity. When a heavy object hanging from the lamp falls, it pulls a string in the center of the lamp, which starts a small in-house generator.

The generator converts the energy generated by the falling weight into electricity for the lamp. This is the same principle as a hand-cranked power generator, except that the direction of movement of the gravity lamp is more perpendicular.

It only takes a few seconds for the weight to be placed, and as it slowly descends, it generates enough power to keep a light on for 1 hour to several hours.

As long as you reset the weight yourself every hour to a few hours, you can have a green, battery-free, constant flow of light. Other similar devices, such as battery chargers, can work in the same way. (Real Modern Products)!

The "gravity lamp" relies on gravity to generate electricity, and its brightness is equivalent to a 12 to 30 watt fluorescent lamp, and the service life can reach 200 years. Of course, only if you damage it artificially!

(Do you feel that if everyone uses it, the people in the power bureau will have to jump their feet?) ）

You think too much, domestic electricity has always been unprofitable for the country. That's why there are documents advocating private power generation, and the State Electricity Administration only needs to earn electricity bills from factories, which is enough!

At present, gravity lamps and various modern high-end power-saving products are only available in major cities in China, and Nanjing just has this condition.

In fact, the Nanjing government is already considering whether to replace all street lamps with gravity lights.

Because of the use of this kind of thing, one is to save electricity (, it is directly to use electricity without money), and the other is that there is less chance of damage, as long as some people are regularly arranged to press the button and let the thing be reset. Even environmental protection workers can be allowed to work part-time and increase their wages. The best of both worlds!

The third is to give people a sense of high face. (Face engineering, you know.) ）

Zhu Zilong was very interested in these things, and after getting some membership cards for some of his employees, he took some lessons from the gym teacher and asked for contact information. It's in the city!

Soon, Zhu Zilong purchased a batch of bicycle generators for himself, as well as gravity lamps.

The bike is Manoj Bhargava from BillionsinChange, which not only generates the power needed by the bike itself through the pedals, but also provides a family with 24 hours of power after pedaling for an hour, and people can turn on the lights, turn on the fan and charge their phones or tablets at the same time.

Why, stronger than the gym owner's? The reason for this is that this is an American product, and the price is high. Up to about 10,000 yuan!

The gravity electric lamp is also a high-grade one, and no one will repair it if it is broken in the Ming Dynasty, so if you want to choose a better one, Comrade Zhu Zilong has nothing else, and now the poor only have money.

Before leaving, the boss proposed to him again, do you want to have a set of photovoltaic power generation equipment?

Zhu Zilong stopped again with great interest, photovoltaic power generation is a technology that uses the photogenerated volt effect of semiconductor interface to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (components), controllers and inverters, and the main components are composed of electronic components.

In other words, it is a popular solar power generation device.

However, because this is the first NNN generation product, it uses a reinforced material, so there is no need to worry about being damaged after crossing.

In line with the idea of experimenting and feeling that it may be reliable, Zhu Zilong purchased more than a dozen sets of photovoltaic solar strengthening equipment.

When loading the car, the playful Zhu Zilong bought something else.

Then, go straight to the seed station.

In the countryside or county town, if you want to buy seeds, you generally go to the Academy of Agricultural Sciences.

There are similar places like this in Nanjing!

Some people say that rice is not grown in the north, and wheat is not grown in the south.

If you do, you're very wrong.

In fact, as long as the climate, terrain, soil, water and other conditions meet the growth of rice, it is fine. The rice in the northeast of China is still the best quality rice in China!

There are also wheat growers in the south, which cannot be generalized, only near Yantai, where Zhu Zilong is missing, if he grows rice, he can definitely do it.

The people live on food!

In the years when non-staple food was scarce (Ming Dynasty), the per capita consumption of grain was a large amount, and the people who did manual work in those years used pots the size of soup bowls in our homes today.

If you can let go, let them eat. There is no oil and water, no meat, and we only rely on food, and today our family of three burned half of the rice cooker's rice, and we could even eat it until the next day.

However, these people can eat it in one meal, and they may not be full.

Natural disasters continued in the late Ming Dynasty, so the food problem was the top priority for Zhu Zilong.

The main product he wants to bring back is high-yielding crops such as hybrid rice and potatoes!

In 1980, after China's first agricultural technology patent was transferred to the United States, the average yield of China's indica hybrid rice per mu was 165.5%~180.3% higher than that of the country's rice varieties!

The emergence of hybrid rice fundamentally solved the shortage of staple food rations for the Chinese, and similarly, it could also solve the problem of eating for the Ming Dynasty. Oh, even if it's a province. Therefore, this is a technology that must be introduced!

At that time, the United States obtained the transfer of hybrid rice patents at a cost of 2 million US dollars, and in 2020, it will be available for hundreds of thousands of yuan.

As soon as Zhu Zilong entered the Nanjing Institute of Agricultural Sciences, after explaining his intentions, the other party was not ambiguous.

Early rice varieties? It's coming! Medium rice varieties? It's coming! Late rice varieties? Yes, drought-tolerant and cold-tolerant!

At this time, China's newly developed hybrid rice is already the fifth phase of super hybrid rice, with a yield of more than 1,200 kilograms per mu. Zhu Zilong is still confident!

According to Zhu Zilong's understanding, the yield after the weighted average yield per mu in the north and south of the Ming Dynasty was 2.31 Akashi raw grain per mu of Ming Dynasty.

One mu in the Ming Dynasty is equivalent to 0.9216 mu now, and the yield per mu in the Ming Dynasty is 343.424 city catties per mu on average.

"In the first year of Hongwu, there was a division, and the seven counties of the prefecture were given land endowments, and the tax per mu was one liter."

It can be said that the people of the Ming Dynasty lived very hard, very difficult, and it was time to let the first productive force of science pull them along. At the same time, give yourself a little more power!

Taking out the computer, Zhu Zilong calculated.

I have more than 10,000 acres of fields in the Ming Dynasty, and I need 1-1.5 kg of hybrid rice seeds per mu, and the average price of hybrid rice seeds ranges from 20-40 yuan per kilogram.

Counting the best kind, about 50 yuan per kilogram, one mu of light seeds plus some other costs, about 100 yuan.

One acre of 100 yuan, ten acres of 1000 yuan, 100 acres of 100,000 yuan, 100,000 acres, 10,000 acres of millions, in order to spare, and fear of losing part of the crossing. Prepare more, buy a 5 million yuan seed back, the first phase should be enough!

In the next minute, the section chief on the opposite side heard that Zhu Zilong wanted such a large amount.

I was taken aback on the spot, and wondered if it was a major grain grower in any province in China that wanted to change rice in an all-round way?

So many seeds! Rice seeds have a shelf life, if you don't plant them this year, will you eat them next year? But then again, the seller is afraid that people won't be able to buy too much, and there is no reason in the world, as long as you want it, take care of it.

After the last bargain, the seed company sold this large batch of rice seeds at a discount of 20% price, and in addition, transferred the cultivation technology of three varieties of high-yield wheat seeds.

Both sides are happy to reach a comprehensive cooperation!
