Chapter 507: Microwave eliminates four pests

"Teacher Ding, this sparrow smells so good, much better than roasting it over fire."

Xiong Cheng, the number one disciple who followed Ding Bijun into the mountain, used a wooden stick to pick up a roasted sparrow that was still spitting out oil. He could smell the aroma from a distance.

The person in charge of the construction of the antenna array next to him also approached and commented seriously:

"Except for the hair on one side of the belly, which is mushy due to accumulated heat, the other parts are really evenly heated. The inside and outside are heated at the same time. If the heat is controlled more, the meat will be much more tender.

My hometown used to sell this, but if it wasn't cooked well it would taste very bad, so this way it just tastes right. "

Standing next to the flat-panel array antenna, Ding Bijun's face was full of black lines. He wanted to kick the sparrow to death but was afraid of getting oil on it. In the end, he could only give up with a couple of grunts.

First space-based power transmission test - 50% successful.

Back to ten minutes ago, the Chiwu-0.12 satellite in the sky accurately limited the microwave beam within the range of the antenna array. The solar energy from outer space reached the ground after a distance of light seconds, and was then efficiently converted by the receiving coil. for electrical energy.

For 10 minutes, Chiwu-451's average power generation was 447 kilowatts, transmission power was 375.5 kilowatts, and the ground received and converted power on average was 84 kilowatts, with a transmission conversion rate of %.

The efficiency is much lower than expected, with 7.5% less power, but it is acceptable and still very good.

The temperature of the receiving antenna is also okay. When the outdoor temperature is 17 degrees Celsius, the temperature of the receiving antenna only rises to 24 degrees Celsius and remains unchanged. The temperature is controlled quite well.

However, after a while, the control room suddenly found that the efficiency was slightly reduced. Immediately, the outdoor infrared detection station sent an early warning, saying that an abnormal temperature point was found at the antenna. For safety reasons, the control room immediately shut down the microwave of Chiwu No. 1. Transmission antenna and scurried over to check it out.

In the end, it was discovered that a sparrow fell on the antenna somewhere and was roasted by microwaves with an average power of 447 kilowatts.

This poor sparrow first became dizzy due to the huge amount of microwave radiation, so that it lost the ability to struggle, and then its entire body began to be evenly heated from the inside out.

But this heating power is just fine. After 36000 kilometers of scattering, the power distribution range of 447 kilowatts has reached 12500 square meters. The power per square meter is only 36 watts, so it will not burn to death.

Unfortunately, the place where it lies happens to be near the center of the receiving antenna. The antenna array will concentrate most of the microwaves into a small area through the reflecting surface, so the heat from other places continues to accumulate at the contact point, and the accumulated heat rises rapidly. The side he was lying on started to get heated, and when Ding Bijun and others arrived, the inside was almost cooked...

This can only be regarded as a small accident. The transmission test itself was quite successful, but the transmission efficiency was somehow lower than expected, but the 84% efficiency can actually be put into practical use.

"The trees here are too dense. At first, we only considered the Qinling Mountains, which has little clutter impact and is close to Chang'an. I'm afraid it will have a very negative impact on the ecological environment in the future.

At least all the surrounding trees should be cut down to prevent small animals from interfering. It is better to move to an open area in the future. "

Xiong Cheng's face collapsed after listening to his mentor's words:

"Teacher Ding, we are not going to the Great Gobi."

"That's not possible." Ding Bijun scratched his hair. Although the conditions in the Gobi Desert were good in theory, he didn't want to go to the Gobi Desert.

"In fact, in the future, the antenna can be made into a semi-closed paraboloid, which can not only concentrate microwaves but also prevent interference. However, the construction cost is too high and it will not be used during the test. I'd better contact them to cut down the trees.

You should immediately contact Xinyuan Company and the Sichuan government, tell them that the test was very successful, and quickly transfer the remaining half of the second batch of funds. In addition, Kuafu Company’s upgraded solar cells must be mass-produced by the end of this year. Poor cost control is a problem. "…

Beijing.

Frank Yang walked on the campus of Tsinghua University on crutches. Students and teachers passing by all greeted him warmly as usual, and he nodded politely in response.

But as soon as the students passed by him, they would gather together to whisper and look at him from time to time.

The reason for this is that a big event has happened in the past few days. A reporter from China News Agency reported: Frank Yang, who once firmly opposed the establishment of accelerators, now strongly supports the establishment of high-energy accelerators!

There are all the evidences in black and white, audio and video, and it is not a small or medium-sized accelerator. We need to build a super circular proton accelerator with a circumference of more than 100 kilometers and charge towards the last barrier of cutting-edge physics!

As soon as this news was released, it immediately aroused heated discussion across the country. When Frank Yang returned to China, he believed that the national power at that time should not be built accelerators that were useless to people's livelihood, and he really did this.

Later, starting in the 10s, some people in society began to emphasize the importance of basic science, but Frank Young did not speak out, always feeling that the time was not yet ripe.

He opposed accelerators as soon as he returned to China in 1970, and continued to oppose them in the 80s, but the Institute of High Energy Physics resisted the pressure and established BEPC.

In 2012, Wu Yunfeng said that he would build CEPC. When it came to the 100-kilometer electron-positron collider, Frank Yang's attitude remained unchanged. Five years later, has he finally waited for this moment?

Although there is no official news yet, it is widely rumored that the new proton accelerator will be named "TEPA (Three-hundred trillion Electron volts Proton Accelerator)", which means 300Tev proton accelerator.

Rumor has it that this TEPA project will be completed in two phases, with an investment of 240 billion yuan in the first phase and 870 billion yuan in the second phase. The total cost is about 1100 billion yuan to build a 140-kilometer-circuit accelerator, which is more than five times larger than the LHC. .

In addition, a new National High Energy Physics Research Center will be built together with TEPA, with an investment of approximately 70 billion yuan, to further improve domestic basic scientific research capabilities to the internationally leading level.

So when the superiors got on the plane back to Beijing, the popular news headlines had become:

"Frank Young proposes spending $2000 billion to build accelerators."

"More than 170 leading physicists, including Hawking, and more than 1000 domestic scientists have jointly approved the launch of the TEPA plan, and many of the world's top universities have also expressed support."

"Lin Ju: Invest 100 billion yuan in basic science!"

"In an interview, Liu Cixin denied the feasibility of building a super accelerator along the equator, saying it was just a science fiction idea and that scientists in reality are even greater."

"Nobel Prize winner Francois Engler: If TEPA is completed, he is willing to conduct research in China. TEPA is a great breakthrough."

"The Baidu voting results are out. More than 7500% of the 80 million participants agreed to donate to the construction of the accelerator. The importance of basic science is deeply rooted in the hearts of the people."

"..."

As soon as the plane landed, the superiors started shaking people, not from the Institute of High Energy, but from the Ministry of Finance.
