Hand rubbing nuclear fusion live in the wilderness

Chapter 290 Solving the Energy Problem
When Han Yuan revealed his plan, the live broadcast room became lively in an instant.

Some were skeptical, some didn't believe it, and some quickly realized that the anchor was going to show off his black technology again.

But soon the topic moved on to other aspects.

But the people from various countries squatting in the live broadcast room are different.

Almost as soon as Han Yuan's voice fell, everyone's hearts skipped half a heartbeat at the same time, and then they started beating violently.

However, no one spoke, and all the experts and scientific researchers stared at the live broadcast with wide-eyed eyes, looking forward to Han Yuan's next explanation and live broadcast.

The information revealed this time is too shocking.

This reminded the experts in the live broadcast room of the previous black technology "electric propulsion-free fluid engine".

90.00% of the people above [-] in the live broadcast room don't know how much electricity an electric propulsion-free engine consumes per hour.

Even if South Korea won the process of manufacturing electric propulsion-free fluid engine, the whole process is broadcast live.

But how long has passed now, this time is simply not enough for human beings to understand the technology of electric propulsion engines.

Even the vast majority of countries do not even have the ability to reproduce it.

Even with this industrial foundation and ability to reproduce it, there are not many.

And even if it is reproduced, targeted tests are still in progress, and the test data is still top secret.

Although no one in the live broadcast room knows the precise figure of the hourly power consumption of an electric propulsion engine.

However, these experts can still estimate the approximate power consumption.

After all, the Korean won was also broadcast live during the test.

The five largest hydroelectric generators start at the same time to supply the operation of an electric propulsion-free working medium engine, and there is still surplus electricity, which can supply the operation of two water pumps.

Based on this data, the experts and scientists in the live broadcast room can roughly calculate the approximate value of the hourly power consumption of an electric propulsion engine.

It is calculated by the speed of the vertical water wheel, combined with the speed of the water flow, and then counting the speed amplification of the transmission gear and so on.

The power of such a hydroelectric generator should be about [-] kilowatts per hour, and the power difference is about the same as that of a medium-sized hydroelectric generator.

This should be almost the limit of this small river.

Even if the anchor built a dam using the waterfall terrain with rapid water flow, its power would not exceed this figure by much.

No matter how powerful the power is, the water flow of this small river cannot be moved.

This is due to the fact that this small river is located in a tropical rainforest, which is rich in various water resources, and this natural waterfall has formed a sufficient drop and terrain that can be used.

Otherwise, with the diameter of this small river less than ten meters, it would not be able to carry such a powerful generator at all.

Calculated according to this value, even if all the electricity generated by the five generators is supplied to the electric propulsion engine, the electricity consumption per hour is [-] kilowatt-hours.

In other words, the power consumption of an electric propulsion engine is about [-] degrees per hour.

[-] baidu electricity sounds like an exaggeration, it is almost half a year's electricity consumption of an ordinary household.

But this level of power consumption is extremely low for an electric propulsion engine that can provide a thrust close to 150 kN.

Judging from the data calculated by themselves, these experts who are not qualified to obtain detailed test data and operating principles of electric propulsion-engines are so shocked.

Because this is an incredible, impossible thing to do.

Compared with the aviation fuel consumption of fighter jets in various countries, [-] Baidu electricity is less than a drop in the bucket.

Take Da Maozi's Su-27 fighter jet as an example.

The total amount of fuel contained in the Su-27 fighter jet is 9.7 tons. If no maneuvers are performed, the Su-27 fighter jet will only cruise and the flight duration will be about three hours.

Calculated according to this data, the fuel consumption of the Su-27 fighter jet is close to 3.3 tons per hour.

And how much electricity can 3.3 tons of aviation fuel generate?

The fuel consumption of a 500KW diesel generator is almost one hundred kilograms.

3.3 tons of aviation fuel, even if calculated according to ordinary diesel, is enough for a 500KW generator to generate electricity for 33 hours.

In addition, this is only cruising fuel consumption. Cruise flight belongs to the lowest level of flight fuel consumption. The cruising speed of the Su-27 is only about Mach 0.8, and there is no supersonic speed, and this has reached 3.3 tons per hour.

But don't forget that the Su-27 is capable of supersonic flight, with a maximum flight speed of Mach 2.35. Under supersonic flight, fuel consumption will increase sharply.

Compared with fighter jet engines, from the perspective of fuel consumption properties, the energy consumption of the electric propulsion-free propellant engine prepared by this anchor is unbelievably low.

It is precisely because of this that countries attach so much importance to electric propulsion-free working medium engines.

The thrust is not much different, but the fuel consumption is only about one-tenth.

This kind of technology, which country can't see it with envy?

Thanks to the global live broadcast, if it appeared in a certain country alone, tsk tsk.
However, the black-tech-like electric propulsion-free engine was like a deep-water torpedo that stirred up huge waves in the hearts of experts from all over the world. Before it subsided, the anchor threw another huge bomb.

'Solar panels' that supply electricity to electric propulsion engines!
This piece of information contained a huge bomb thrown out, which once again blew up all the experts in the live broadcast room.

Although the fuel consumption of the electric propulsion-free medium engine is very low in comparison, the power consumption per hour is also [-] Baidu.

This is still one.

And there are six of them on the aircraft.

The six electric propulsion engines started at the same time, consuming a full [-] kWh of electricity per hour.

Is this value really affordable by solar panels?

Even experts who are not experts in the solar power generation panel industry know very well that it is impossible to achieve this level with the solar power generation panels currently manufactured by humans.

To what extent will the photoelectric conversion efficiency of the solar power panels that can supply the flight of the aircraft be terrifying?

50.00%?
60.00%?
Or 70.00%?eighty?Even breaking through one hundred?
Does this technology mean that human energy problems can be solved?
After all, there are two constraints on the development of human science and technology 'at present', one is materials, and the other is energy.

As for theory or something, there is no shortage of 'current' humans.

A lot of theoretical mathematics, theoretical physics and other aspects of knowledge, human research on it has far exceeded the current level of applied technology.

Science and technology are two completely different concepts.

Science is the understanding of the laws of nature, the principles.

And technology is the application of principles, that is to say, science is the mother of technology.

In fact, many cutting-edge technologies are currently being used by humans, and their theories are still from the last century.

For example, GPS technology relies on the theory of relativity published by Einstein 80 years ago;

The theoretical basis of nuclear weapons and nuclear power generation is Einstein's mass-energy equation;

Even the two front-end technologies of quantum computer and quantum communication, which are still in the laboratory theory stage, can be traced back to the Planck era.

If a careful person counts, he can find that the theoretical basis of modern technology basically comes from the last century.

Let’s look at human’s energy utilization technology. For thousands of years, human beings have used energy by burning fire and water.

However, in the 21st century, when science and technology are highly developed, the main way for human beings to use energy is still to burn fire and water.

It's just that modern people's way of burning fire has become more advanced.

Thrust from internal combustion engines, car engines, aircraft rockets.

Although it is technically [-] or [-] times more complicated than burning torches in ancient times, from the perspective of energy utilization, they all obtain energy through chemical combustion.

Including the acquisition of electric energy, it is actually the same.

Even today, more than 65% of the world's power sources still come from various thermal power sources.

For example, coal power generation, gas power generation, oil power generation, etc., these are all burning fire and water.

In addition to thermal power, the proportion of other power generation is roughly as follows.

Hydropower accounts for about 16%, nuclear power accounts for about 10%, wind power accounts for about 5%, solar power accounts for about 2%, and the rest is some other energy sources, such as geothermal, tidal, garbage, and biological power generation. wait.

Among them, solar power generation accounted for only [-]%.

Yes, this kind of clean energy power generation, which has been highly praised all over the world and vigorously developed, actually accounts for a pitifully low proportion of the total power generation.

The reason is actually very simple.

'Photoelectric conversion efficiency' can't be improved all the time!

At present, the common solar panels on the market only have a conversion efficiency of about 15.00% to 20.00%.

Even if it is a product in the laboratory, its photoelectric conversion efficiency is only about 40.00%.

Both crystalline silicon cells and solar thin film cells have their own limits in this respect.

In fact, those solar cells with reported photoelectric conversion efficiencies exceeding 40.00% are all tricky.

In the report, the so-called photoelectric conversion efficiency exceeds 40.00%, but it does not mean that the conversion rate of monolithic silicon cells or thin-film cells exceeds 40.00%.

Photoelectric conversion efficiency is defined.The power divided by the cell area is the conversion efficiency.

The conversion efficiency of polysilicon is about 15.00%, the conversion efficiency limit of single crystal silicon is about 18.00%, and the compound silicon material may be higher, but it will not exceed 30.00%.

However, humans can use various technologies such as shingled technology, half-chip technology, and perc battery technology to improve photoelectric conversion efficiency.

Therefore, the photoelectric conversion efficiencies of 40.00%, [-]%, or even [-]% reported for solar power generation are actually taken into account.

Rather than referring to the conversion rate of monolithic silicon cells or thin film cells.

In addition, in addition to the difficulty in improving the photoelectric conversion rate, there is another key point that restricts the development of solar power generation.

That is the current solar power is expensive.

Whether in terms of raw materials or power generation costs, photovoltaic power generation is several times more expensive than ordinary coal power generation.

If the cost of one kilowatt-hour of coal power generation is [-] cents, then the cost of one kilowatt-hour of photovoltaic power generation is one yuan.

Although photovoltaic power generation is clean energy, but it is so expensive, who else is willing to use it?
In the final analysis, the photoelectric conversion efficiency is still too low.

As a result, the cost of photovoltaic power generation is high and cannot be used.

But what about the solar panels prepared by this anchor?
Just laying the upper half of an aircraft can supply six electric propulsion engines.

How terrifying is this photoelectric conversion efficiency?
So when Won announced that he planned to use solar power panels to solve the problem of aircraft power supply, the whole world was shocked.

The energy problem, is this going to be solved?
If we can learn this kind of technology, I am afraid that most of the thermal power plants and nuclear power plants in the world can be dismantled.

In particular, nuclear power, a power generation method that produces extremely polluting and difficult-to-handle nuclear waste, can be discarded directly.

In order not to secretly discharge nuclear waste water into the ocean to pollute the whole world like some countries after the accident of the nuclear power plant.

There is little courtesy but no great righteousness, and he is still unwilling to admit his mistakes. The Prime Minister stood up and apologized, and he was discharged openly.

Just don't be too nasty.
