Another world opens up, Metaverse.


Metaverse = Meta + Universe

It is a combination of “meta” and “universe”, meaning “virtual world”.
Metaverse is a place where countless people and countless contents gather in a transcendent virtual space, and you can live a life as good as the real world in it.
It is an expanded concept than existing virtual reality, and the boundary between the virtual world and the real world is broken down.


Academically, the Acceleration Studies Foundation (ASF), which many researchers refer to in relation to Metaverse, defined Metaverse as a “physically enhanced fusion of physical reality and physically sustained virtual space.”
In addition, the Institute of Electrical and Electronics Engineers viewed Metaverse as an “advanced Internet of persistent three-dimensional virtual spaces connected to a perceived virtual world”.

The first person to use the concept of Metaverse is known as Neal Stephenson, an American science fiction novelist. He first used the concept of Metaverse in his 1992 novel Snow Crash.
The novel features a fictional character named Avatar in the main setting of the fictional world of Metaverse.

He entered a virtual world where computers created and continued to supply his goggles and earphones. In computer terms, it was a world called Metaverse…(omit)…They built buildings, made parks, and built billboards. Not only that, but it has also created things that are impossible in reality.

Snow Crash : Neal Stephenson

Metaverse in the movie.

Metaverse can also be found in movies. In particular, Steven Spielberg’s film “Ready Player One” is highly regarded for its good implementation of Metaverse.
Steven Spielberg’s 2018 film “Ready Player One” is based on a novel of the same name written by Ernest Christy Klein and set in the future of 2045 dominated by a virtual reality game called Oasis.
From the 1980s to the present, many characters were gathered in a space called Oasis, encompassing all pop culture contents. Oasis, a virtual world in the movie, is said to have visually expressed the concept of Metaverse as a space where avatars can be made from various games and movie characters.

In an oasis, each avatar moves in the same way as the individual’s free will, rather than as a character in a regular game. Even though it is virtual reality, it is a space that is similar to real reality, where various jobs exist, a company creates a large enough force to exert great influence on the virtual world, and each has its own secret space, and in it, it buys and produces its own materials.

Of course, you can exchange and trade various items in the Oasis space.
The characters in the film perceive Oasis as another reality, not just a space for games, and share their experiences in both reality and the digital world. Although it is sometimes ridiculous for the characters in the movie to wear AR devices, the film is considered one of the best expressions of Metaverse.

Why are you interested in Metaverse?

The biggest reason for interest in Metaverse is that it will become a virtual world that connects and fuses with the real world.
And Metaverse is also a new version of the Internet that we’ve experienced. It is a different dimension from the Internet so far, a virtual space with continuity without being disconnected from reality.
It can complement reality, make it convenient, and try things that cannot be achieved in the real world, as well as have social, economic and political connections to the real world.

Since the introduction of the concept of a fully interconnected worldwide network in 1982, the Internet has had a huge impact on our lives since the mid-1990s.
The Internet has changed our way of life in a wide variety of areas, ranging from e-mail and messengers, Internet calls and video calls, blogs, and online shopping.

Then, the spread of smartphones, which emerged with 4G services in 2007, once again caused a wave of change. In the process, companies such as Amazon, Apple, Microsoft, Alphabet, and Facebook accounted for the top market capitalization group.

Metaverse is expected to make a difference once again in the world after the advent of smartphones.
Although the concept of Metaverse is not new, technological advances in hardware and software and content that has increased user satisfaction have been highlighted as the connection between the real world and the virtual world is strengthened. If Metaverse in the past was the second concept to fill the shortcomings of the real world, it is now established as the “first” concept that fuses with reality and interacts with it, which is equivalent to reality.

Metaverse in the past

One of the contents that played an important role in Metabus’ attention was “Second Life,” released by Linden Lab in 2003.


Second Life provided an experience of living a “second life” by interacting with others through avatars in a virtual space called the Internet.
Users enjoy parties, drive cars, etc. in a virtual world. It was an early sandbox-type service that preceded Roblox and Minecraft, which have recently become popular, and it was the prototype of Metaverse business models.

Metabuses in the present


Roblox is said to have joined 60% of Generation Z in the U.S.
In the U.S., parents with young children are so popular that they worry that their children may fall into a virtual world and neglect their studies.

Roblox is a platform for communicating with other participants in the virtual world, making friends and creating communities while directly manipulating characters that may appear in Lego.
You can raise pets with other users or do various hobbies together. You can also experience superheroes like Superman. Users can purchase items through a virtual currency called Robux.

Roblox grew rapidly as children in the U.S., who were unable to go to school due to Covid-19, were spotlighted as a channel where they could connect with their friends, and as Covid-19 increased their use of games. There are now more than 1.6 billion users. Several games have also been released within Roblox.

More than 10 million users are active every month, and more than 5,000 games have been played more than 100 times. Roblox is designed to allow users to create their own games and play them by using its own game engine, Roblox Studio.
In this situation, the job of a creator who creates and sells content within Roblox is also emerging. Creators can create content and sell it to Roblox. Roblox reportedly paid more than $200 million to creators last year alone.


Fortnite is a third-person shooter video game released by Epic Games in 2018.

The genre is Battle Royale, which is enjoyed with 100 players. In 2020, the number of users worldwide exceeded 3.5 billion and American celebrities and sports players who are enthusiastic fans of Fortnite games are enjoying popularity to the extent that they follow important moves in the game on air or on the field.
In April 2020, famous American rapper Travis Scott held a concert at Fortnite Virtual Space. It attracted 12.3 million people and earned 21.6 billion won on the same day.

It is considered one of Metaverse’s most successful examples of creating economic added value beyond physical time and space. As such, a concert is held in Fortnite’s virtual space, Party Royal, and trailers of new movies are screened. BTS also unveiled the choreography of their new song Dynamite for the first time here last year. It also sells character products such as Nike and Marvel.


Minecraft is mentioned as a representative example of Metaverse as Roblox and Fortnite. Mojang Studios, which developed Minecraft, was acquired by Microsoft for about 3 trillion won in September 2014.

Minecraft is a game where you build your own world by building up square blocks like Lego. As a kind of sandbox game, you can think of it as a form in which children can play with it by putting sand in a large box made of wood. With a high degree of freedom, avatar in the game is given the ability to create a new environment on their own in addition to free action.

By giving them the maximum freedom to do whatever they want in the game, game users can freely change the environment in the game. They build buildings and create a city. Users can also be said to be true creators of the world.


Naver is a platform company that has more than 35 million MAU (Monthly Active Users) and has unique competitiveness in advertising, commerce, content and fintech.

Based on the advantages of having a large number of users and many other people using Naver’s services, Naver believes that it can lead the related market in the Metaverse era in the future. Naver has already succeeded in Metaverse, called life-logging, through services such as Naver CAFE and BAND, and operates services such as ZEPETO, SNOW, and V Live.

In addition, Naver Maps containing real-time local information, IDC and Cloud, which can handle big data, will also be highlighted on Metaverse. For example, ITZY, a girl group affiliated with JYP Ent, not only filmed a music video for “Not Shy” using Geppetto, but also held a fan meeting.

YG Entertainment girl group BLACKPINK also held a fan meeting using ZEPETO. With face-to-face events impossible due to Covid-19, fan meetings using ZEPETO have become part of fan service, and it is meaningful that it can be a means of fan service that transcends physical limitations even at the end of Covid-19. In the case of online concerts, rather than through avatars, the actual artist’s performance video is being streamed, but effects that are difficult to implement in reality are replaced by AR/VR.

Metaverse, which seemed to be in a science fiction movie, and was thought to be possible in the distant future, is creeping into our lives. Even if you don’t have a device like a VR headset, you can spend time online through your avatar and social life.

It is clear that it is an attractive market in that it is highly popular in Generation Z, which will be the mainstay of the future, and it is possible for various companies to enter and expand the market by combining Metaverse.

Metaverse related companies are moving.

The Metaverse market is growing rapidly, such as the development of new technologies such as AR, VR, and 5G. Not only Roblox, which is listed on the New York Stock Exchange, but also Mesh, a mixed reality platform introduced by Microsoft, NVDIA Omniverse, a 3D collaboration platform released by NVDIA, and NAVERZ, which has more than 100 million users by releasing ZEPETO service in 2018.

The market has been formed mainly by game companies, but now leading global companies are newly entering the market as it is highlighted that it can expand to other industries, marketing aimed at Generation Z, future potential customers, and scalability.
Recently, fashion companies are releasing clothes and accessories for avatars.

Engineering Education and Personality Education

a symbol of engineering

There are growing voices saying that personality education needs to be strengthened.

It is pointed out that the growing conflict in society is all due to the lack of personality education in schools. And there is a big fuss about teaching philosophy, history, and literature to all the students, and even educating them to emphasize the importance of filial piety.

Personality education is especially important for science and engineering students.
The concern is that the problem will be really serious if science and engineering students who will be in charge of science and technology, who will exert greater power in the future, do not have enough personality.

Instead of contributing to the development of society, scientists and engineers with science and technology in the background can become scary Frankenstein and disrupt society.


Coursera, an online education service that offers online lectures by world-class scholars, offers self-reflection meditation lectures provided by KAIST Korea.

The title is “Meditation: Away to achieve your goals in your life.” Professor Lee Deok-joo of KAIST, an authority in aerospace engineering, gave a lecture in English.

Coursera has 140 leading universities, including Stanford, Harvard, MIT, Johns Hopkins, Yale, KAIST and the University of Tokyo, with approximately 1,500 courses and over 17 million members.

It covers almost all humanities and natural sciences, including humanities, business administration, law, newspaper broadcasting, science and engineering, and self-reflection meditation falls under the categories of humanities, education, and engineering.

Professor Lee introduces the necessity of self-reflection, principles and practical training, and meditation methodology that changes me in six weeks in an easy-to-understand manner. The lectures are composed of various subjects with fundamental and integrated characteristics, including scientific application of mind subtraction meditation, practical training, and interviews with related experts.

Lee Duck-joo graduated from Seoul National University in 1977 with a master’s degree and a doctorate from Stanford University and worked as a researcher at NASA for three years, and has been a professor of aerospace engineering at KAIST since 1988. he was the head of the task force for civil and military helicopter development.

He also played a major role in the development of Korea’s aeronautical engineering, including the development of Korea’s first helicopter ‘Surion’ and the launch of Korea’s first space projectile ‘Naro’.

It was four years ago that he, an engineer, paid special attention to students’ personality education in addition to his major, following a series of suicide incidents by a KAIST student. Related Articles

Professor Lee gave meditation courses titled “Turning Points in My Life” and “Exploring and Recovering from Human Nature” to meet the needs of his students in human education, which received a great response.

Coursera’s meditation course is based on these experiences and the results of field education.

Professor Lee said, “I can objectively reflect on my life through mind subtraction meditation based on self-reflection. If I remove negative minds through meditation, I can learn how to live my life freely and completely.”

mind subtraction Meditation is a scientific meditation method that has been popularized by the meditationlife Society since 1997. It maintains more than 200 meditation centers in Korea, and there are meditation centers in major capitals around the world.

Professor Lee Deok-joo has studied the educational effects of mind subtraction Meditation and has published numerous papers.

Professor Lee Deok-joo’s self-reflection meditation course is categorized as a meditation field and can be watched continuously.

Innovative companies such as Google, Facebook, and Amazon recognize the value of the Cocera Certificate when hiring employees, and the U.S. Board of Education and European Credit Transfer System (ECTS) review the lecture and may grant credit if they pass the credit rating.

History of Mars Exploration, Perseverance


Mankind’s first Mars specimen collection spacecraft has arrived on Mars, the first runner in the “10-year relay space expedition,” which brings Martian soil to Earth.

NASA’s “Perseverance,” a robot rover, arrived safely at the “Jezero” impact port in the northern hemisphere of Mars at 3:55 p.m. Wednesday local time. It has been six and a half months since he left the earth on July 30 last year.
The cumulative flight distance was 470 million kilometers.

All three Mars probes, including Amar of the United Arab Emirates and Amar of China, have arrived on Mars this month as scheduled.

NASA’s Perseverance project team released a picture of the landing immediately after landing, saying, “It was a perfect landing as shown in the picture.”

Perseverance sent us two photos of the surface of Mars taken with cameras attached in front and back.

U.S. President joe Biden said on his official Twitter account, “I want to congratulate everyone, including crew, who worked hard to make the historic landing of the Perseverance possible. Today, it is proved once again that nothing is impossible with scientific power and U.S. ingenuity.

The Perseverance, a six-wheeled probe weighing 1,050 kilograms, three meters long and 2.2 meters high, is the 15th Mars rover in the U.S. and the fifth one.

There are two main tasks for Perseverance, the same structure as Curiosity, which has been in operation for nine years. It is to find traces of past life and collect soil samples from Mars for the first time in history.

The process of landing on Mars, whose atmospheric density is only one-hundredth that of Earth, is called “seven minutes of fear.” It is because the atmospheric friction force, which can reduce the speed of the spacecraft, is low and there is a high risk of ground collisions.

On this day, Perseverance had to put up the curtain and endure the high temperature of 1300 degrees Celsius, slowing down the speed from 20,000 kilometers per hour to walking speed in just a few minutes. For this reason, parachutes, reverse propulsion engines and sky cranes were mobilized.

NASA has also added new technology this time for a safe landing. After continuously taking and analyzing surface photos during the descent, the landing site can be changed to within 600 meters if necessary.

Landing Process ©NASA

The “Seven Minutes of Fear,” which lasted in three stages, began when a descending line (sky crane) with solar panels removed, entered the atmosphere at 8:48 p.m.

After enduring high temperatures for about a minute, the descending line extended its parachute four minutes later, slowing it down to 1,500 kilometers per hour.

Two minutes later, the rear heat shield was removed when it reached 2.1 kilometers above the sky.
From this point on, it slowed down with a reverse propulsion engine and slowed down to 2.7 kilometers per hour. The descending machin(ship) lowered a rover connected to three nylon wires (7.6 meters long) at an altitude of 20 meters.

After confirming the landing of the rover, the descending line cut off the connecting line and flew to safety. The Perseverance had a speed of 2.5 kilometers per hour when it landed.
All these processes were carried out with built-in automated control systems.

Communication between Mars and Earth takes as long as 22 minutes and cannot be controlled in real time by the Earth control station.

Expectations are high for finding traces of life.

With regard to the discovery of traces of life on Mars, NASA has higher expectations than ever before for this expedition. This is because of the characteristics around the impact port of the Jezero(Slavic word for lake) where Perseverance will operate.

Jezero is the 45-kilometer-wide collision basin at the northwest end of the Equatorial Wisidis Plain. Scientists estimate that it is an impact basin formed by the fall of a large meteorite 3.9 billion years ago. It is located in the Triangle Plain, which is believed to have been formed by the deposits of rivers formed by the heat, dust, and gas jetting from volcanic activities 4.1 billion to 3.7 billion years ago.

Scientists believe that there is a high possibility that there are traces of life in the triangular province, which is fan-shaped in the east direction. If the river flowed at that time, Samgakju would have been a gathering place for organic substances. The truth is that screw scientists have long been anxious to explore here.

However, due to the unevenness and steepness, the ship could not be sent due to the high risk of landing. Thanks to the development of technology, the company achieved its long-cherished wish.

Another place where scientists expect traces of life is the lakeside.

Scientists believe that there is a rock-like lump of carbonate on the edge of an ancient lake that stretches along the edge of the Jezero on a photograph of Mars.
There is evidence of fossilized bacteria-like lifeforms called stromatolites in ancient carbonate rocks on Earth.

Sherlock (SHERLOC) and PIXL (PIXL) play a central role in “Searching for Life” among the seven scientific equipment installed in the Perseverance. Sherlock uses ultraviolet lasers to find organic substances, and Pixle analyzes rocks and soil components.

The Mars specimen collection will be carried to Earth 2031 years later.

Perseverance’s initial activity period is set at one year (based on Mars Day, 687 Earth days).

During the same period, Perseverance travels around the area at a speed of 152 meters per hour and collects Martian soil and stones in cylindrical metal containers.

Full-scale activities will begin in May after the system inspection and commissioning are completed. There are 43 sample collectors.

However, I will leave the five empty.

This is to compare whether or not the container containing the specimen contains pure Martian substances when it is brought to Earth later.

If you search for rocks to collect, extend the robot arm (2.1 meters long) and drill a hole the size of a small flashlight (6 centimeters long by 1.3 centimeters wide) and place the samples in the container.

Each container can hold up to 15g.

The cylindrical container is 15 centimeters long and is made of titanium.
It is coated in white with high light reflectance to prevent deterioration by sunlight.

Once 20 containers are filled, bury them in the ground first and store them.

NASA plans to send another spacecraft to collect the samples in the late 2020s and then bring them to Earth in 2031.

Therefore, NASA and the European Space Agency decided to send two probes to Mars in 2026.

NASA has decided to take charge of the Sample Recovery Lander (SRL) and the European Space Agency will take charge of the Earth Return Orbiter (ERO). The two spacecraft will reach the surface and orbit of Mars in the summer of 2028.

Ingenuity ©NASA/JPL

A helicopter is flown to test the generation of oxygen on Mars air.

Perseverance also performs two special tests on Mars. One is the flight test. At the bottom of the ship, the Ingenuity, a small helicopter weighing 1.8 kilograms, 1.2 meters in wings, and 50 centimeters in height, hangs. Screws move the Perseverance to a flat area and then conduct flight tests. Five attempts in 30 days from mid-March.

The flight test will be conducted by rotating the two wings 2,400 times per minute in opposite directions to generate lift and fly. It is powered by solar cells. “My goal is to fly 5 meters up and 150 meters back and forth for 90 seconds. If successful, the “Ingenuity” will be the first powered flying vehicle that has been flown by humans outside of the Earth.

NASA expects this will pave the way for drone exploration on other celestial bodies in the future. “The goal is to prove that aerodynamics works on Mars as well,” said Tim Canham, head of operations at Cognitive News.

The other is the oxygen generation test. This test uses carbon dioxide, which accounts for 95 percent of Mars’ atmosphere, to produce oxygen. After inhaling the atmosphere of Mars with a device called MOXIE, they plan to conduct experiments to remove dust and pollutants and convert carbon dioxide into oxygen. It is an important test to prepare for future manned Mars exploration.
Conduct 10 experiments to generate 6 to 10 grams of oxygen per hour in different seasons and times.

8 trillion won joint project between the U.S. and Europe

In addition, Perseverance has 23 cameras including surface radar (limfax), weather observation equipment (meda), two high-resolution cameras (supercamera and mastcamera Z), and two microphones. One of the two microphones is in the landing system and the other is in the camera. A microphone in the landing system records the landing process. Camera microphones are used to determine if the rover is abnormal. NASA has invested $2.7 billion (3.2 trillion won) in mass 2020.

NASA and the European Space Agency estimate that it will cost about $7 billion (8.5 trillion won) to complete the Mars specimen collection-return project. Currently, U.S. landers Insight and Rover Curiosity are performing missions on Mars.

With the addition of Percybeerance, the Mars rover increased to eight orbiter(US 3, Europe 2, India 1, United Arab Emirates 1, China 1), one lander(USA) and two rovers (USA).

In May, China’s Tianwon 1 (landing ship and rover) will come down to the ground and join.

Mars is geologically alive.
(The meaning of Mars exploration.)

There are already many traces of humanity on Mars. Among them are twin robots, which have overcome many crises and hardships and impressed mankind, and mobile rovers such as the “Curiosity Rover,” which celebrate their birthdays.

However, there is not only a mobile probe on Mars. There are also fixed probes (landers) like Phoenix probes.

The Phoenix fixed probe is NASA’s fixed Mars probe, which landed in the North Pole of Mars, which is rich in water and ice, and was the first to directly collect samples of Mars. After landing, Phoenix began to search for traces of water on Mars and ultimately see if Mars is the right environment for life or microorganisms to live in.

Finally, they succeeded in finding steam by heating frozen soil specimens. Based on Phoenix’s success, NASA selected the Interior Exploration using Seismic Investigation, Geody and Heat Transport project as its 12th discovery program. Since the name of the Insight means “surveying the interior of Mars using seismic waves, geodesy, and heat transfer,” the main purpose of the probe was geological exploration of Mars.

The initial launch plan for the Insight Explorer was scheduled for March 2016 but was delayed somewhat due to a defect in the SEIS (Seismic Experiment for Interior Structure) seismograph and was eventually launched in May 2018. The Insight probe, which traveled 484 million kilometers, sent its first signal after landing on Nov. 27, 2018. Landing on Mars is a fairly difficult task consisting of three stages: approach, descent and landing.

First of all, when reaching the top layer of the Martian atmosphere with an altitude of more than 100 kilometers, the speed of the probe should be reduced rapidly. In addition, heat sinks must withstand excessive temperature due to friction with the atmosphere. Next, when the plane reaches 10 km above the sky, it spreads its parachute and slows down, ending its careful landing. After landing, the Insight probe immediately deployed two solar panels to power Mars.

Insight after Mars Landing ©NASA/JPL

The Insight landed on the Elysium Plain near the equator of Mars, but this is one of the flatest places on Mars. The chosen landing site has something to do with the free operation of solar cells because the Insight probe is not a mobile probe.

The choice was made with the utmost consideration of external hazards as well as adequate sunbathing. Since the main purpose is geological exploration of Mars, the Insight is equipped with two cubes: the SEIS seismometer called Mars Cube One (MarCO-AMarCO-B), the Heat Flow and Physical Properties Package, and the Rotation and Interior.

In addition, the Instrument Deployment Arm is a feature of only the Insight Explorer, but it was installed for the purpose of installing SEIS seismometers and temperature measuring instruments. In particular, the two cubes installed by the robot arm are one of the most important equipment.

The first cube, the SEIS seismometer, is a device capable of sensing earthquakes and vibrations of less than 50 hz, and is designed and manufactured by more than four large national-level laboratories. Just as earthquakes have made it possible to predict the Earth’s interior, Marsquakes are also important information for tracking the interior of Mars. If an earthquake occurs on Mars, the interior of Mars can be predicted by changes in wave motion.

In addition, the heat of the current Mars nucleus can be measured using the second cube (MarCO-B), the temperature measuring device for drilling equipment, and the activity inside Mars can be determined. Measurement of internal temperature also provides important hints for planetary evolution, but it is possible to predict the overall information on Mars and the life of the planet based on the degree of cooling of Mars. It is believed that there was a time when Earth and Mars looked like brother planets.

Mars is also expected to have a thick layer of atmosphere with warm temperatures, but now it looks like a completely different planet, including a very thin atmosphere due to various reasons, such as a weak magnetic field caused by the changed interior. Exploring the veiled interior of Mars and the atmosphere will help us understand the process of forming a terrestrial planet.

Dr. Laurie Grays, head of NASA’s Planetary Science Department, reported in April 2019 that she had captured the first Martian earthquake. Unexpectedly strong earthquake activity on Mars is similar to the moonquakes detected on the Moon during the Apollo mission, but it is not enough to accurately explore the interior of Mars.

As of September 30, 2019, a total of 450 large and small earthquake signals were detected to indicate that Mars is living geologically, but most of them were due to seismic activity inside Mars and the impact of meteorites on Mars. Insight brought new and surprising results.

Dr. Katherine Johnson, one of the deputy managers of the Insight Explorer, reportedly discovered a magnetic field on Mars that was about 10 times stronger than that observed by satellite. The metals inside Mars began to cool long ago, but this eventually led to Mars’ weak magnetic field and the absence of an atmosphere to protect it from solar winds. For this reason, these discoveries are predicted to be local, implying that there are magnetized ancient rocks underground near where the Insight Explorer landed.

In June 2020, the Heat Flow and Physical Properties Package of the Insight Explorer finally began digging the land. The device, nicknamed the Mole, is designed to be drilled up to five meters underground. Since it contains heat sensing sensors, it can measure energy and temperature from inside Mars while digging into the ground.

However, the mole failed to enter the ground despite several attempts so far, and scientists and engineers who were thinking of other alternatives decided to use the robot’s arm to push the mole equipment into the ground. So the mole started digging land on Mars on June 9, 2020.

The Insight Explorer is scheduled to finish its mission this year, but there is still a lot left to do. There are still many mountains to cross. As winter approaches the northern hemisphere of Hwaseong, dust storm season is expected to begin soon. This means the Insight probe could face sandstorms and other crises experienced by the twin rovers. It also means difficulties may arise in mole drilling activities.

Furthermore, since the Insight Explorer is a fixed probe, it is feared that it will be able to overcome the crisis completely. Mars is a perfect place to learn how terrestrial planets were born and evolved. We hope that the mole will be active in solving many mysteries.

The previous electric vehicle and the Mars exploration content are all related to Elon Musk’s dream.
As an engineer, I had a lot of fun writing. The preliminary research for writing was a great inspiration for me. I hope that those who read this text will take a lot of inspiration with themselves.

The advent of the electric car, Tesla!

Model S

In the 19th century, two scientists in the U.S. engaged in a battle over the transmission method of electricity. It’s called “Current War.”
The main characters of the war are Thomas Edison, who insisted on the DC system, and Nicola Tesla, who insisted on the AC system.

Nikola Tesla

George Westinghouse, who used to supply electricity to the entire U.S. through Edison’s direct current system, chose Tesla’s alternating current system, and the war ended with Tesla’s victory.
Tesla will then completely redesign its AC-based generator and prime mover.
In 2003, Martin Everhard and Mark Turpenning thought of electric cars as a way to curb global warming and started a company to build electric cars in a completely different way.


Tesla Motors is named after Tesla, which first developed alternating-current induction motors. In 2004, Elon Musk, founder of SpaceX, a private space company that succeeded in the online payment system PayPal, joined Tesla with the investment, and Tesla began to accelerate the development of electric vehicles with a step forward.

In addition to the characteristics of electric cars, which are “clean, quiet and environmentally friendly,” they changed everything with the imagination that if they could drive more fun, safer, and travel farther on a single charge, they would surpass the world’s dominant gasoline cars.

In July 2006, his imagination became a reality. Tesla’s first mass-produced electric sports car, the Roadster, has been unveiled. Those who thought electric cars were golf carts and shuttle buses were enthusiastic about the sports car “Roadster,” which can run 400 kilometers on a single charge and reach 100 kilometers per hour in four seconds. The media criticized the billionaire Eran Musk, who dreamed of traveling to Mars, as a “delusional man,” and made him a revolutionary, and Tesla began to attract public attention. With the addition of the identity of Eran Mask, Tesla continued to be attractive.

Model S /

Tesla = “S3XY” electric vehicle

Since the roadster, Tesla has started developing Model S in order to release electric cars that are completely different from existing cars. A prototype Model S with battery cells placed inside the trunk on the floor for safer and faster electric vehicles was unveiled in March 2009.

Tesla recorded its first surplus in its 10th year of existence when the sedan Model S, which can operate 470 kilometers on a single charge, was introduced in 2012.
In 2015, the Model X, an SUV electric vehicle equipped with a Falcon wing door, was unveiled. The Falcon wing door could be opened and closed upward and received a great response from customers with children.

In 2016, the mass production system was established and the Model 3 was released, and in 2019, the Model Y, which is the most dangerous for drivers in the event of an accident, was introduced and safety-enhanced. Tesla has now completed its ‘S3XY’ product line with models ‘S’, ‘3’, ‘X’ and ‘Y’.

Tesla is breaking with conventional practices and making electric cars that are not in the world. At the root of this differentiation is careful consideration for drivers. No matter how bright an idea is, if people don’t feel the value, it disappears without creating any differentiation.

The more people feel the value, the more differentiation shines. Don’t you think Tesla looks more attractive because many people sympathize with the value Tesla created?
