Bill Gates, one of the richest people in the world, recently delivered a speech on the social platform about the future car. Referring to electric cars, he said: electric semi-trailers and electric jets will probably never appear.

Although there is no name, the electric semi-trailer truck referred to by Gates reflects Tesla's semi-electric truck to some extent. Gates believes that semi-trailer trucks have large load capacity and high power requirements, so more batteries are needed to provide power for vehicles, and batteries will become bigger and heavier, which is not a practical solution for trucks, cargo ships and airplanes.

Of course, Gates did not completely deny electric cars. In his view, electric vehicles are very suitable for passenger cars, and he is also the owner of the Porsche electric sports car Taycan. In the field of commercial vehicles, he said that heavy and long-distance transport vehicles need another solution, and biofuels will be the solution to replace batteries.

When Gates, one of the richest people in the world, proposed to use cleaner energy to power vehicles, Tesla CEO Musk felt offended. Recently, on social platforms, Musk responded to fans: Bill Gates knows nothing about electric trucks.

According to Tesla's mass production plan, Tesla Semi electric truck will be mass-produced in 20 19 at the earliest, but due to various reasons, the mass production of this model was postponed to 202 1 year, and in the earnings conference call in the second quarter of this year, Musk also confirmed the mass production plan of Semi electric truck.

Tracing back to the listing time of Tesla Semi, we have to trace back to the Los Angeles conference on 20 17 1 1. A semi-trailer truck without rearview mirror appeared in front of people, without the big nose of an American truck and the high sitting posture of a European truck, leaving only a front face like a high-speed train. ...

Semi electric truck is built on the skeleton of Model 3, and the front and rear four wheels are driven by independent motors. The specifications of the motor are consistent with model 3. In terms of parameters, the maximum horsepower of Semi truck exceeds 1000 PS, and it only takes 5 seconds to accelerate 100 kilometers under no-load condition. Officials also give that when carrying 36 tons of goods, its acceleration time is only 20 seconds. Compared with ordinary trucks, the performance of this Semi is undoubtedly "Mars" level.

In terms of Bill Gates' most pessimistic cruising range, the cruising range of Semi electric trucks is also 300-500 miles, that is, the minimum cruising range is 483km, which is no different from the current passenger car-class electric vehicles. In terms of energy consumption and replenishment, the Semi electric truck consumes less than 2kwh/ mile, and can travel 400 miles, or 644km, after 30 minutes of charging.

Although at the data level, the Semi electric truck can reach a certain level in power and endurance, the outside world doubts that the battery technology bottleneck will be the main reason for the ticket jump of Tesla Semi electric truck. If Tesla can't come up with batteries with higher energy density to expand the output power, the mass production of Semi electric trucks may face greater obstacles.

Bill Gates and Musk are not communicating for the first time. Although they are in different industries, they formed an indissoluble bond as early as five years ago at the Boao Forum in Asia.

In 20 15, Bill Gates and Musk were invited to attend the Boao Forum in Asia and had a brainstorm on artificial intelligence technology. At that time, the relationship between the two was not close, and most of the conversations were "business contacts." By 20 17, Bill Gates also praised Musk's work in the field of new energy in public.

However, in 20 18, after Bill Gates bought the Porsche Taycan, their friendship boat began to be unstable, and Musk also responded: "I once talked to Bill Gates, but it was boring."

It can be seen that the relationship between Bill Gates and Musk has turned sharply, and this year Bill Gates directly pointed out the infeasibility of the Tesla electric truck project, and Musk also responded to show his dissatisfaction.

The war of words between the two bosses can make many netizens happy, but as we all know, Musk is not an empty talker. Obviously, this unrestrained entrepreneur will not stop at his opponent's remarks. At present, Bill Gates has raised a question about electric trucks. Presumably Musk will fully overcome the mass production problem of Tesla Semi electric trucks.

In September this year, Tesla will hold the Brand Battery Day as scheduled. According to foreign media reports, Tesla will announce its latest battery "Million Miles" on Battery Day, which will use a new generation of "single crystal" NMC 532 cathode and a new advanced electrolyte. With the addition of new technology, electric vehicles can run continuously for 100 miles, which is also the origin of the name "million miles".

In addition to the "million-mile" battery, Tesla's previous preheating technologies include cobalt-free battery, dry electrode technology and silicon nanowire technology. To this end, Tesla also plans to purchase a large number of low-carbon nickel metals from Canadian mining companies to meet the needs of subsequent battery research and development and production.

The arrival of battery day also affected Tesla's share price. On September 14, Tesla closed up 12.58%, and the price per share was $465,438 +09.62, which was the first rebound after Tesla experienced a sharp drop this month.

Tesla's battery day will probably be Musk's best counterattack against Bill Gates. Bill Gates believes that electric trucks need to be loaded with heavy batteries to improve battery life. Musk once revealed on social platforms that the energy density of new batteries can be increased by 50%. Take the battery energy density used in the current Model 3 as an example. If it can be increased by 50%, the battery life of this Model 3 will easily exceed 1000km, and it will definitely have a good battery life when applied to Semi trucks.

With the continuous breakthrough of battery technology, Musk is also more confident to fight against commercial giants. Although this is also a brand marketing strategy, it is undeniable that Tesla is indeed at the top of the industry technology pyramid. Whether electric trucks or electric planes can be terminated by words, as long as people who dare to keep trying appear, the future of electrification will go further.
