Qianyan completed the upgrade in the early morning. An hour later, Xiaotang came to the medical care area, ignored Xia Ming's arms, and woke Xia Ming up with a snoring little fun. n∈

"Get better, let's start." After enjoying a breakfast in advance, Xia Ming cheered up and connected Qian Yan. Qian Yan's virtual image appeared in front of him and smiled gently: "Hello, Xia Ming, please give me instructions."

Xia Ming asked: "How do you feel?"

"The world has become bigger, I see farther and my thinking is sharper," Qian Yan Rourou said, Xia Ming raised his thumbs up to Xiaotang, Xiaotang raised his chin and accepted the praise without hesitation.

For Qianyan, the "world" is the problems and knowledge that her thinking can touch. When she becomes stronger, she can understand more problems and think faster. For her, the world has expanded. And exerting such ability is the meaning of her life, if she really has life.

"You should have a few directions already." Xiaotang didn't leave, and wanted to help Xia Ming complete the "gesture".

Xia Ming did have some directions, including conventional batteries, fuel cells, and solar energy is also an alternative, and nuclear batteries and even small nuclear reactors are on the list. If other roads cannot be completed, no matter how risky he is, he has to choose the nuclear route.

"Is there hope for graphene batteries?" Xia Ming first talked about the conventional direction.

Xiaotang rolled his eyes: "Are you still a scientist? Do you believe in such civil sciences?"

The concept of graphene has been popular for many years. It is a crystal formed by connecting a single layer of carbon atoms in graphite. Because it is only as thick as one atom, it is a two-dimensional structure from a macroscopic perspective.

The discovery of graphene has been talked about by scientists so far. The two British men used tape to stick the graphite apart layer by layer, and finally the two-dimensional graphene existed.

Because of its single-layer grid structure with carbon crystals, graphene has excellent performance in terms of strength, light transmission and electrical conductivity. It is called a new generation of "universal material" by mankind.

If the material strength is not enough? Add some graphene. If the electrical conductivity is insufficient? If the material strength is not enough? If the material is not high, the thermal conductivity is not high? If the material is not high? If the material is not high, the material is not high.

This is nothing. Graphene is also claimed to be the core cornerstone of the next generation of computers. The conductive properties of graphene have also made many people highly expect it in the field of energy, such as the application of batteries. Graphene batteries are touted as an energy star that runs 1,000 kilometers in 10 minutes of charging.

But graphene, at least the graphene industry in recent years, is more of a bubble hyped by public opinion. The biggest problem is that graphene is a two-dimensional crystal, and its large-scale commercial production is still a technically insurmountable hurdle.

The public opinion's hype over graphene is to confuse the different applications of graphene as microscopic and macroscopic fields. Not only graphene, but also in all nanomaterials, there are such problems.

Graphene as an additive can strengthen other materials in many directions, but this change is not revolutionary. Speculative capital is more willing to exaggerate how many new applications graphene will create and have a revolutionary impact on many fields.

But those directions they render are the application of graphene when it exists alone as a macroscopic.

Graphene as an additive can be obtained by simply processing graphene. However, if graphene can be used alone, it is not the small structure dissociated from the graphene powder that can be done with it, nor can it be used to make large graphene by using small pieces of graphene. Remember, it is a two-dimensional crystal.

Media serving speculative capital have been advocating how much graphene prices have fallen, which marks how mature the graphene industry is. These media will never tell the public that there is another dimension of graphene prices: area.

1 gram of graphene is a structure with an area of ​​less than 1 square micron. No one can make graphene with an area of ​​one square meter so far. Only companies such as Samsung and ibm have now built hundreds of square centimeters of graphene, but the price of a single piece starts at 1 square centimeter and 100 US dollars. The larger the area, the higher the average price.

Speculative capital is the application of this kind of graphene that is hyped by the media. In reality, everyone is still looking for various applications of graphene as an additive. But investors don’t know, so in China, the “graphene concept stocks” have been very popular for several years. It was not until a few years later that these companies have not made anything. The graphene fever gradually cooled down. As for another big pit that is similar to the photovoltaic industry, speculative capital doesn’t care about this kind of thing. They have made enough money in the stock market and the government.

"It's unfair." Xia Ming defended: "Of course I know these, but have you made a breakthrough?"

That's right, Xiaotang's outer packaging for researching the anchor mark assembly has not made much progress, but unexpectedly lit up another branch on the graphene manufacturing technology tree.

By editing the DNA that cloned neurons, she created a special protein that can adsorb graphene in an electric field. The principle is similar to the CVD production and preparation method, but the matrix was replaced with protein. In her materials laboratory, twenty square centimeters of graphene have been produced. If it weren't for Xiaoping's surgery during this period and Qian Yan's upgrade, she would have almost broken the records of Samsung and ibm.

Xiaotang gave Xia Ming another blow: "Do you know that the so-called graphene battery is simply a lie?"

"Um...ah?" Xia Ming quickly asked Xia Xiaoyan to find information. After a while, he also smiled bitterly.

It's really a lie. There is a problem with the concept of "graphene battery". Graphene as an additive to the cathode can increase the charging speed. This is true, but there are also some side effects, which are difficult to evaluate. No battery company has spent money on that little charging efficiency. As for graphene as anode, it seems to have greatly improved the battery capacity in theory, but the large specific surface area brought by a single layer of carbon atom structure deviates from the existing battery process principles.

"The prospects that graphene materials can currently expect are flexible electronic screens, flexible electronic components, and the production of new generation computer chips mixed with silicon crystals, etc. Graphene batteries need to overturn the existing battery industrial system to achieve it, and their performance is still on the same level as existing batteries."

Just in the few minutes when Xiaotang and Xia Ming were nagging, Qian Yan had also given an evaluation report.

Xiaotang sighed: "I think it's better to be more secure in the direction of nuclear batteries. Of course, there are real risks to do this."

Nuclear battery reversal is indeed feasible, at least it has been put into practical use in the aerospace field. China's "Tiangong-3" space station used nuclear batteries. The American Curiosity rover, which boarded Mars seven years ago, also installed nuclear batteries, so there were no solar panels, which really made many people curious at that time.

Nuclear batteries are not that scary either. The old-fashioned pacemakers used to use nuclear batteries.

However, nuclear batteries are divided into two categories: one is to provide electricity by radiation, and the other is to convert electricity by thermal energy. The former has a pitifully small power, so if you want to use it as power, you can only use the latter. The latter material is generally plutonium 238, which requires the conversion of thermal energy into electrical energy.

"The electric furnace with a thermal power of 1 kilogram of plutonium 238 is equal to 570 watts. The nuclear battery device of the Curiosity rover weighs 45 kilograms and generates power of 140 watts. The nuclear battery of the Cassini-Huygens Saturn exploration spacecraft has a power of 880 watts. If improvements are made on the existing basis, a 500 kilogram nuclear battery pack can achieve 3 kilowatts of power generation."

"But it is not enough to promote the 10 MW VA private speed to an average speed of 104,000 kilometers per hour in two months. The total design weight of the entire detector is 1.2 tons. If the detection equipment is 200 kg, the design weight of the 10 MW VA private weight cannot exceed 500 kg. The structure and weight of the 200 kilowatt VA private weight is analyzed. The possibility of achieving this goal within fifteen months is less than 20%.

"In addition, in public information, the United States has the capacity for large-scale production of plutonium 238, with an annual output of less than 1 kilogram, which is a core strategic resource of the country. The isotope plutonium 239 is used for nuclear weapons manufacturing, with a production cost of US$5,000 per gram, and the production cost of plutonium 238 is at least twice that of 239."

"Even if the United States is willing to sell plutonium 238, it is not allowed to leave the country. All the engines and detectors can be handed over to the United States, with the United States assembled and launched."

Qianyan's analysis cut off Xia Ming's idea of ​​using nuclear batteries. Looking at the various battery technologies listed by Qianyan in the A-view, Qianyan said: "If the weight of the detector is limited to 500 kilograms and the rocket is sent to a high orbit of 40,000 kilometers. Given the detector enough initial velocity, then with the improved solar cell technology, a 200 kilogram solar cell pack can power a 300 kilogram 1 MW V-MR, allowing the detector to fly to Zhishenxing within 90 days. According to the academic data I have searched for, the possibility is more than 70%.

Qian Yan is indeed a powerful Gei. After understanding Xia Ming's general idea, he used his quicker and more accurate thinking ability to find a barely feasible solution, but...

Xiaotang asked: "What should I do if the detection equipment and control system are detected?"

Xia Ming's eyes flashed, and he saw hope: "Squeeze 100 kilograms of margin from the battery and the engine, and use the neuron chip to make the control system, the weight is very small, and the detection equipment...just just the camera and searchlight."

"Qianyan's fanatic!" Xiaotang also understood: "The good idea is that it is not easy to explain to the people you recruit. And, what if it's not like collecting three components, just relying on seeing them?"

Xia Ming said: "This is the first step, the faster the better. When we take the first step, we will prepare for the second step immediately. If we only need to look at it, it means we are lucky. If not, the second detector can continue to go to heaven. We even have to prepare for the third step and send people over."

Solar cells are just emergency responses, which does not mean that they can let go of energy. Xia Ming still needs to make breakthroughs in energy technology as soon as possible, otherwise he will not be able to support the second step plan.

"This is a lot of money. I hope our companies can hold on," Xiaotang sighed quietly.

Xia Ming said calmly: "You have to do it even if you sell it."

The next day, the members of the Springboard project team happily contacted Qianyan and then received Xia Ming's voicemail.

Xia Ming's voice was a little hoarse, but what he said made everyone happy.

The plan changes, and we will start to develop a 1 MW Van Private MR first. This is not difficult. With super gei, the equipment and materials are complete, and it only takes up to half a month to conduct feasibility verification. If everything goes well, the feasibility verification will be directly transferred to real-time manufacturing. It is optimistic that it will be up to two months.

The next command stunned them, and they got 1 MW and then got 10 MW!

"Xiao Xia is really crazy," Dongfang Sheng muttered, but like everyone else, he was stunned for a while, and a smile that was even brighter than before appeared on his face.

It is no longer a crazy gambling, but a little bit more serious and the cycle is longer. Of course, it is a great thing for scientists.
Chapter completed!
