Metropolis: I am a technology tycoon

The new energy sources recognized around the world generally refer to wind power generation and solar power generation. Before 2010, there was a wave of vigorous construction of wind power generation equipment and solar power generation equipment around the world.

It is a pity that this craze gradually disappeared after wind power generation and solar power generation were put into practical use.

Because wind power generation and solar power generation have a common flaw, that is, unstable voltage. What any country’s power grid needs most during the power supply process is stable voltage and current.

Thermal power generation is currently the most stable and efficient way of generating electricity that humans can control.

And the power supply of the power grid is actually a real-time power supply process. Simply put, the power plant will only generate electricity when residents use electricity. It generates as much electricity as you use.

It’s not that the power plant generated 10,000 kilowatt hours of electricity today, but residents only used 8,000 kilowatt hours of electricity, and the remaining 2,000 kilowatt hours of electricity were stored and used tomorrow. That’s not the case. If you use 8,000 kilowatt-hours of electricity, the power plant will generate 8,000 kilowatt-hours of electricity, no more, no less.

The reason why people feel that there is electricity when they turn on the lights is because the electric energy stored in the capacitor is being buffered. The charging and discharging of the capacitor are instantaneous things. This is a physical process, that is, the capacitor stores electric energy. What is also released is electrical energy.

Unlike batteries, batteries convert electrical energy into chemical energy when storing energy, and convert chemical energy into electrical energy when discharging, and can continue to discharge slowly.

With the electric energy stored in the capacitor as a buffer, the power plant can generate electricity according to the user’s needs. When the user does not use electricity, the capacitor will replenish the consumed electric energy and then generate electricity. The plant stopped generating electricity.

Although thermal power generation is stable, it will encounter peak problems. That is, during peak power consumption, the pressure on thermal power generation will be great, and the pressure on the power grid will also be great, and there will often be insufficient power.

Wind power and solar power are not stable enough, so at least 40% of the electricity is wasted every year.

And there is another way of generating electricity, which is hydropower generation. Hydropower generation is also a relatively stable way of generating electricity, but hydropower generation also has waste problems.

For example, today’s residents’ electricity demand is 10,000 kilowatt-hours of electricity, and water conservancy power generation also generates 10,000 kilowatt-hours of electricity. But you must know that everyone has a time to take a break and turn off the lights, but water is constantly flowing, and hydropower can always generate electricity.

But people don’t need electricity, so what should we do? Excess electricity cannot be stored and can only be wasted.

But if there are supercapacitors, the situation will be different.

Capacitors store electrical energy and release electrical energy. However, ordinary capacitors have too small capacity for electrical energy and cannot play a key role.

Supercapacitors are different, with large capacity, high power density, long cycle life, wide operating temperature limit, maintenance-free, and green environmental protection.

The supercapacitor can be charged and discharged 500,000 to 1 million times, and after reaching the rated charge and discharge times, the characteristics of the supercapacitor will change very little, and it can still be used until the power storage efficiency drops to 100%. After seventy years, the capacitor can be replaced with a new one.

If you want to create supercapacitors, you need to overcome the issues of power density, safety, self-discharge, and cost.

Galaxy City developed a graphene supercapacitor last year, with a power density of 1,000 watts per kilogram and a rated charge and discharge number of 800,000 times. Safety issues can be solved with nano-diaphragms, and the cost is as low as 200 yuan per kilogram..

Compared with Yingzhou State, which is currently at the forefront of developing supercapacitors, it has a power density of 150 watts per kilogram and a rated charge and discharge number of 600,000 times. The safety problem has not been solved and the cost is 2,300 yuan per kilogram.

Galaxy City’s graphene supercapacitors undoubtedly surpass several levels.

In addition, Galaxy City has already mastered high-efficiency solar power generation technology. Today’s solar power generation technology in the world has a utilization rate of 15% to 18% of solar energy.

The solar power generation efficiency developed by Galaxy City has reached 32%, and the utilization rate of solar energy has been greatly improved.

With graphene supercapacitors, when wind power, solar power, and hydropower are used, the originally wasted electrical energy can be stored, increasing the proportion of new energy in the country’s electricity consumption, and reducing the pollution problems caused by thermal power generation.

And with graphene supercapacitors, the peak power consumption problem during thermal power generation can be alleviated.

Graphene batteries have a storage capacity that far exceeds that of lithium batteries. Galaxy City’s electric motors and electric control technology have been tested long ago, and now graphene supercapacitors are available.

It can be said that Galaxy City already has all the conditions for the leap from fuel vehicles to the era of electric vehicles. In this case, there is no need to hesitate.

The fire in Taihang Shenling was completely extinguished in just five days. 2015 passed and 2016 ushered in.

Lu Xingfan’s guess was correct. On March 15, 2016, a new energy conference led by the government and attended by all automobile companies, energy companies, and more than 2,000 scholars and professors from across the country was held in the capital. Lu Xingfan Also included in the invitation.

Regarding the promotion of new energy and electric vehicles, some people agree, some oppose, and some remain neutral. It’s okay for those who remain neutral, but those who agree and oppose are just quarreling with each other at the conference, and they are almost fighting.

The reason for those who agree is very simple. The era of new energy and electric vehicles has many benefits, the most important of which is environmental protection. Nowadays, the pressure on environmental problems is increasing, and it has reached the point where some economic benefits must be sacrificed to alleviate environmental pollution.

The reasons for those who oppose it are also simple and crude, that is, the problem of energy waste, laid-off workers, and the cost of electricity.

Those who agree and those who oppose dislike each other. After both parties took the stage, they explained their opinions and then started to quarrel. The scene was fierce and spectacular, and no one was convinced by the other.

When Lu Xingfan came on stage, everyone opened their eyes wide and concentrated. Anyone with a little knowledge of the City of Galaxy knows about it across the country, and the City of Galaxy’s world-leading team of scientists is even more famous.

As Lu Xingfan, who single-handedly founded the City of Galaxy and looked down upon all sentient beings in the scientific community of Yanlong Kingdom, everyone naturally wanted to know his thoughts.

Lu Xingfan glanced at the thousands of people in the audience, and then said:”I won’t go into the benefits of new energy and electric vehicles. The people who agree are also based on this point, and the people who oppose are just worried about energy waste and layoffs. There are worker issues and electricity cost issues.

Let’s put these aside for now. What I’m going to talk about today is graphene supercapacitors based on graphene materials. Here I can clearly tell you that Galaxy City has developed a power density A graphene supercapacitor with a power of 1,000 watts per kilogram and a charge and discharge cycle of 800,000 times.”

Boom! Everyone looked at Lu Xingfan on the stage in shock as if they were struck by five thunders.
