I collect gold fingers in the heavens

Chapter 475 Advanced Technology

Honestly, there are a lot of good things on Mars.

For example, in the habitat cabin, Wu Siyuan used the oxygen generator, or the oxygen generator.

Oxygenation machines, also known as carbon dioxide absorbers, can continuously convert carbon dioxide into oxygen and carbon monoxide as long as they have enough energy. It is an essential machine for manned aviation, space exploration, and interstellar colonization.

There are also such products in the real world where Wu Siyuan lives.

The most advanced among them can be said to be the MOXIE that is being tested, that is-the experimental device for the utilization of Mars oxygen resources!
The Mars oxygen generator MOXIE is only the size of a toaster. It can collect carbon dioxide in the atmosphere of Mars. After internal processing, it releases carbon monoxide and oxygen. The entire conversion process is carried out in an environment of about 800°C.

The whole body of MOXIE is made of heat-resistant materials and coated with a layer of heat-insulating paint, which can effectively insulate heat.

But the efficiency is impressive.

In the Martian environment, MOXIE warmed up and worked for 2 hours, during which it released 1 hour of oxygen, and the amount of oxygen produced was about 5.4g, enough for astronauts to breathe for 10 minutes.

And the oxygenator in the habitat cabin is more efficient than MOXIE by a little bit.

Its volume is almost the same as that of the Martian oxygen generator MOXIE, but when the power is sufficient, it can continuously and synchronously convert the carbon dioxide produced by humans through respiration into oxygen and carbon monoxide, and carbon monoxide can be recycled and reused, and its synchronous conversion efficiency Up to more than eighty percent.

Not to mention the heat-resistant materials used in this oxygen generator can operate in an environment exceeding 2100 °C.

If this kind of material is used in the real world, many industries will change.

Take the engine industry for example.

Where is the domestic engine industry lagging behind?
Not even the material!
Of course, Wu Siyuan had no way to deduce its metallurgical formula from a piece of material.

Therefore, if Wu Siyuan wants to obtain the formula of this heat-resistant material, he still has to obtain it from the earth in this world.

Other than that, good stuff on Mars has RTG!

RTG, radioisotope nuclear battery.

"Radioisotope battery" is referred to as an isotope battery, which uses the heat of radioactive decay to generate electricity by temperature difference.

The heat source of a radioisotope battery is a radioisotope.

In the process of transformation, they will continue to emit energy much greater than ordinary matter in the form of heat rays.This great energy has two lovely characteristics.

First, the magnitude and speed of energy released during metamorphosis are not affected by the temperature, chemical reaction, pressure, and electromagnetic field in the external environment. Therefore, nuclear batteries are known for their strong anti-interference and accurate and reliable work.

Another characteristic is that the decay time is very long, which determines that the radioisotope battery can be used for a long time.

Due to the huge temperature difference between day and night on the surface of Mars, general chemical batteries cannot work, and solar cells cannot be used in deep space, radioisotope thermal motors can be described as ideal energy sources for deep space exploration.

This thing was used in the MDV that was launched to Mars in advance to solve the energy problem in the fuel generation process, but once it came to Mars, Mark and the others buried it and specially planted a small flag on it. Remind them to stay away.

Because the contents of this isotope battery are generally plutonium-238.

Plutonium itself is highly toxic. If it is damaged and ruptures, everyone around will have to pay for it.

The most widely used in "radioisotope battery" is the thermoelectric nuclear battery.

So is this one on Mars.

Thermonuclear batteries are also called "radioisotope thermoelectric generators". It is a device that directly converts energy-carrying particles emitted by isotopes into electrical energy. It is made of some semiconductor materials with excellent performance, and these materials are connected in series. On a suitable heat source and transducer, a temperature difference is formed between the heat source and the transducer to generate electricity.

The principle of thermoelectric power generation is the thermoelectric conversion effect, which was discovered by the German scientist Seebeck in 1821, so it is also called the Seebeck effect - a circuit composed of two materials, when the junction temperature is different, a current will be generated in the circuit .

However, the efficiency of temperature difference power generation in the real world is relatively low, and different semiconductor materials are not the same, and the efficiency is between 3% and 10%.

The thermoelectric power generation efficiency of this "radioisotope thermoelectric generator" on Mars has reached 28%!

It is four or five times that of the real world!
This conversion efficiency has reached commercial standards, and there are many application scenarios.

The first thing Wu Siyuan thought of was to use the exhaust waste heat of automobiles to generate temperature difference and convert it into electric energy, which would effectively reduce the power consumption of new energy vehicles.

With the help of this [Temperature Difference Power Generation] technology and the heat-resistant materials mentioned above, [Chaoqun Group] can also enter the field of car manufacturing.

The influence of the automobile industry on the economy is much greater than that of the mobile phone industry.

It is the crown on the top of the industrial pyramid, and the automobile manufacturing industry is a strategic pillar industry of my country's national economy.

In consumption, which is an important domestic economic cycle, automobile consumption accounts for more than one-tenth of the total retail sales of consumer goods in the whole society, accounting for more than 4% of GDP.

Of course, this only includes automobile consumption, and does not include the aforementioned production and manufacturing, as well as the steel and aluminum industries, rubber, petrochemicals, smart chips, and new energy driven by the automobile industry... If it covers upstream and downstream industries, it can be ignored to some extent. It is an exaggeration to say that the contribution and promotion of the automobile industry to my country's economy will be even greater, and this proportion may be roughly estimated to be around 15%.

In 2020, China's auto production and sales will reach 2522.5 million and 2531.1 million respectively!

Just thinking about it made Wu Siyuan's heart skip a beat.

However, the core of thermoelectric power generation lies in thermoelectric materials.

The thermoelectric figure of merit of thermoelectric materials determines the thermoelectric conversion efficiency.

Going around is still related to the material.

And the formula of the material is on the earth.

Got it!
There are many advanced technologies in this world.

But Wu Siyuan had to go to the earth to look for it.

Wu Siyuan had a thought, and the [Four-Armed King Kong] voice came from the external speaker of the habitat cabin, "Master, according to your wishes, the monitoring satellite signals on Mars have been blocked, and it will not be able to observe your movements on Mars." Behavior."

"That's good! We should leave too! Wait for our American hero to come back!" Wu Siyuan nodded and said.

"I believe they will be surprised!" [Four-armed Vajra] replied.

"Hehe..." Wu Siyuan smiled and said nothing. He took away the advanced equipment in the habitat, including the oxygenator, and the isotope battery, put on the Martian astronaut suit, walked out of the habitat, and entered from the [Shennongjiao Space] Summoned the main body of the [Four-Armed King Kong] - the base vehicle.

Wu Siyuan got on the base vehicle.

The base car drives automatically and heads for a place 3200 kilometers away.

There, there is a NASA MAV launched in advance for the Mars landing four years later!
