- Chapter 885 Crazy Face Slap
Is coal power generation a new energy source?
If someone asks this question, whether it is a person in the new energy automobile industry or a passerby, they will definitely say in unison: "Coal power generation must be a backward energy source. How can it be called a new energy source!"
Coal power generation has a history of hundreds of years, and it will produce a lot of pollution and carbon dioxide emissions, so it must be an outdated energy source.
But if someone asks again, is the electricity in new energy vehicles new energy?
Surely most of them will answer, yes.
See, people are such contradictions and paradoxes.
A short video appeared on the big screen at the press conference.
This is not a video shot by Changtian Technology, but a video shot by a popular science video account at Station B.
Among them is a comprehensive evaluation of gasoline and coal power generation.
Take ordinary gasoline as an example, the calorific value of gasoline is 44000kj per kilogram.
At present, the efficiency of fuel vehicle engines is about 25% to 35%. If 30% is used for calculation, then each kilogram of gasoline can actually generate 13200KJ of kinetic energy in the fuel vehicle engine.
?The calorific value per kilogram of standard coal is 29,270 kilojoules, while thermal power plants generally only have a thermal efficiency of about 35-38%, and the loss of electricity during transmission from the power plant to the user is generally 6%-10%.
So in fact, the efficiency of converting one kilogram of coal into electricity is only about 31 to 35%.
Coupled with the fact that electricity enters the lithium battery, the actual loss of lithium battery performance.
Thank God that 30% of the electricity generated by one kilogram of coal can be used in the kinetic energy of new energy vehicles.
So, are new energy vehicles really new energy?
After this short video, a car from the 1950s appeared.
The one or two vehicles are kerosene vehicles, with a large oil bag on the roof, all of which are kerosene.
Chen Xiao joked: "Coal is used as kerosene, and kerosene is used as an energy source to burn directly. The kinetic energy provided to the car may be higher than the kinetic energy provided by using coal to generate electricity and charging electricity into the battery."
"History always repeats itself."
The audience at the scene burst into laughter.
As for the new energy vehicle representatives sitting in the front row, their expressions were very bad.
At the beginning of Changtian Technology's press conference today, it almost smashed the faces of the current global new energy vehicle brands.
It is a logical rejection of the current new energy vehicle model.
Such an opening is quite explosive.
Many anchors who were broadcasting live, this time they had a carnival.
Brother Yan said to the camera: "The opening of the Changtian Technology Cosmic Automobile Conference was so scary and exciting! Chen Xiao directly criticized the domestic new energy vehicle policy, destroying the logic of the current new energy vehicle. "
Brother Yan's live broadcast room also became lively, and the netizens fell into a frenzy.
"My God! Changtian Technology actually compares new energy vehicles with kerosene vehicles in the 1950s!"
"I personally agree with what Chen Xiao said just now. The energy of the new energy vehicles now comes from electricity, and most of the electricity is thermal power. Most of the thermal power is produced by burning coal, so Chen Xiao's Comparably error-free."
"I've always wanted to buy a new energy vehicle. Now it seems that a new energy vehicle is not a new energy!"
"Domestic automobile manufacturing companies hope to break down the technical barriers of fuel vehicles in Western countries and the East through the research and development of new energy vehicle technology. New energy, environmental protection, I don't understand."
"I agree with the above statement. There is a thermal power plant in my hometown. Although the environmental protection investigations have been very strict in recent years, and my hometown is also a large thermal power plant, it is polluted after all. Every time I go back, the city is gray. All kinds of harmful substances must exceed the standard, and the incidence of various cancers in our hometown is much higher than that in surrounding places every year."
Only when there is controversy can there be topics, and only when there are topics can there be traffic.
Less than an hour after the opening of the press conference, countless media have written the bomb thrown by Chen Xiao on the headlines of the front page.
On Weibo, topics such as #新能源车局跟肉汽车# directly rushed into the trending searches.
The amount of discussion on this topic soon exceeded tens of millions. Many bloggers on Weibo were discussing this topic, and soon gained a wave of traffic.
These bloggers felt that they really followed?There is still a long way to go in order to make photovoltaic power generation or hydropower generation account for more than 70% of the public's electricity consumption and reduce the cost to be lower than thermal power generation. "
"In addition, in the production process of lithium batteries, there will also be a lot of ecological pollution problems."
When Chen Xiao said this, three more videos were played on the big screen behind him.
The first video is a lithium ore mining site in Australia.
In the lithium ore mine, all the trees were cut down in the originally lush mountainous area.
The entire mountain was almost hollowed out, and it was dead silent and desolate.
The animals and plants that originally lived here have all disappeared, leaving only the roaring machines and the mined ores.
The second video is the production workshop of lithium batteries.
Lithium batteries also produce serious pollution when they are produced or recycled.
Lithium batteries are composed of positive electrode powder, negative electrode powder, conductive agent powder, binder powder, electrolyte, organic solution and other components. The cobalt in the positive electrode powder is a toxic metal substance, and the organic dispersant is a toxic organic solvent. Liquid is the most toxic and corrosive component in lithium batteries, which has a direct impact on the human body.
The decomposition or hydrolysis products of lithium batteries are hydrofluoric acid and other fluorine-containing compounds, which are also corrosive and toxic to a certain extent, and can damage the surrounding water and soil environment.
Here are some videos of regular factories producing lithium batteries.
The third video is the recycling video of lithium batteries.
Most of the production of lithium batteries are regular manufacturers, but the recycling of lithium batteries is not.
In order to save costs, many recycling plants do not have any environmental protection measures, allowing a large amount of toxic and harmful substances to be discharged into rivers and soil, causing immeasurable losses to the environment.
A line of words was printed on the big screen: "Is this new energy really protecting the environment?"
At the press conference, both the audience and the netizens watching the webcast fell silent after seeing these three videos.
Only then did everyone realize that behind the glamorous new energy, there have always been so many contradictions and unresolvable problems.
In the virtual field.
After a brief silence among many viewers watching the press conference, heated discussions began.
A netizen stood up excitedly and said:
"After watching the three videos played at the press conference, I was quite touched.
My family is in a small village in Huxi Province, where the largest industrial chain is the recycling and dismantling of power batteries. Almost every household is doing this kind of business. We locals don't even dare to eat locally grown vegetables and rice, because the land and water sources are all polluted, and the number of people who die and suffer from cancer every year is even more terrifying. "
"These power battery recycling factories in our village are all small workshops, and have formed a mature industrial chain. They recycle waste power batteries through various channels, directly dismantle waste batteries, and remove the precious metals inside the batteries ( For example, cobalt and lithium) are extracted for secondary sales, or produced into new batteries through simple processing links, and sold directly to car factories.”
"These black workshops don't consider environmental pollution and other issues at all. The damage to the ecological environment caused by this kind of dismantling is absolutely irreversible, and it may be difficult to repair for hundreds or thousands of years."
"Don't think that those large factories that recycle lithium batteries are so noble. In order to save their own costs and meet their environmental protection standards, they are very willing to buy recycled heavy metals and raw materials from those black workshops. After all The environmental costs and risks have been borne by those small workshops, and they themselves are clean."
This netizen's speech was very intense, because the beautiful mountain village he grew up in has changed beyond recognition over the past few years.
Moreover, many of his relatives also suffered from cancer because of this kind of work, and some of them even died.
Perhaps in order to prove that his statement is correct.
The netizen immediately posted photos of his hometown on Weibo and Suichat.
? Black workshops that illegally disassemble lithium batteries are absolutely not allowed to exist, and will be severely punished in law
However, people often take risks for their own interests.
Moreover, this kind of collective crime from village to village really caused a headache for the relevant departments.
At the press conference, Chen Xiao said seriously:
"Based on the above reasons, the sky car built by Changtian Technology will never use lithium batteries."
"We must find a new energy and new energy vehicle that is suitable for the long-term development of the country and is convenient for the public."
"So we launched the Sky Car!"
At this moment, the staff drove Cangqiong A01 car from a distance.
There was an exclamation at the scene."We must find a new energy and new energy vehicles that are suitable for the country's long-term development and are convenient for the public to use."
"So we launched the Sky Car!"
At this moment, the staff drove Cangqiong A01 car from a distance.
There was an exclamation at the scene. - Didn't finish reading? Add this book to your favoritesI'm a member and bookmarked this chapterCopy the address of this book and recommend it to your friends for pointsChapter error? Click here to report
