Citro, it is not a problem to emit more mass to the exhaust than the mass of fuel ...
this is even quite normal since combustion consumes dioxygen and also rejects N2 from the air admitted into the engine without touching it "(except for very residual NOx).
CO2, H2O and other N2, are not a problem, they are not pollutants in the strict sense by dilution in a large volume of air.
CO2 is one as a GHG when the fuel is fossil.
To return to EV, do you believe that electricity does not also produce significant masses of pollutants? Do you compare them?

polluting electric car?
It is especially gases no longer containing enough oxygen to live and NOX that you mention later and which are highly toxic (Cancers, stroke, cardiovascular diseases, ...)Remundo wrote:the Kg of exhaust gas is essentially nitrogen, CO2 and H2O.
: evil: I think I have demonstrated it mathematically. On the contrary, there is an urgent need to inform the population of the importance of the problem and the way in which the real volume of automobile pollution, which was a deliberate intoxication, literally and figuratively, has been concealed.Remundo wrote:Marginal, there is 1% of O2, and 1% of pollutants.
So let's stop "intoxication": a car produces not 1kg of waste per minute!
Seeking as an alibi the fact that "nature" will "quickly degrade" these deadly poisons does not detract from the fact that the exhaust rejects them.Remundo wrote:Among the pollutants, there are NOx, HC, particles etc which are very quickly degraded by nature. They are only a problem in town.
I add that this problem does not only exist in town.
40 years ago, my grandfather almost died on his new tractor, victim of a discomfort caused by the exhaust gases which came out from under the engine and rose in his face with heat.
The tractor was in the open field and without a cabin, which could not be more ventilated for the "gas dilution".
The "problem" was solved by making an upward exhaust outlet so that the gases rise and pass overhead.
Dare to tell me again that the exhaust gases are not toxic waste and explain to me how people die by suicide by this means ... Self-suggestion, perhaps.

I know it, but what percentage of the population is really aware that their vehicle consumes the air of 50 human beings.Remundo wrote:Citro, it is not a problem to emit more mass to the exhaust than the mass of fuel ...
And in this percentage how much has an idea of the real mass and the volume that it represents.
As a teacher, ask your students the question ...

scuze moi Citro, but you have a somewhat fanatic style ... my respects to your Grandfather, of course.
Breathing exhaust fumes pure, everyone knows that it is toxic and even fatal.
But the same goes for N2, O2, CO2, H2O (and even CO for very small quantities).
I know very well what I am talking about, I have never been breathless in a field, even if a 120Hp monster spins a roundballer.
At the edge of a national, the air is not very bad, and the mortal risks are of road origin, and not gaseous.
A vehicle does not "take" the air of 50 people, since the air is ALMOST INFINITE excess in the atmosphere.
The respiratory inconvenience arises in the city, when the vehicles are concentrated, consume for nothing, and the streets confine the air in which a cloud of homo artificialus sapiens petroleus is agitated.
I wrote about these subjects almost 10 years ago now
Studies have even noticed in these cities that the atmospheres of homes and inside cars are more polluted than the outside air by confining volatile organic compounds (VOCs)!

In Les Echos this morning, an article on a senatorial commission of inquiry according to which air pollution in France would cost more than 100 billion euros per year:

It is a choice that I assume, but the essence of my remarks could not be more Cartesian.Remundo wrote:scuze me Citro, but you have a little fanatic style ...
It is not the first time that we have been debating ecological questions with the same technical data and that you have minimized the problems.
Again, I have the feeling that your existence as provincial of the mountains does not allow you to take stock of the situation.
I remind you that the majority of the European population lives in the city and that this phenomenon will intensify, unless the economic situation of Greece extends to the rest of Europe ...
Greece is experiencing an unprecedented urban exodus (8% of the population has left the cities).
So, yes, in urban areas, car pollution is a major problem, because a car consumes the air of 50 people and releases toxic waste for an equivalent volume.
The cities and their surroundings are hot zones, often encased, or the air circulates more and more badly, accentuating the stagnation and the concentration of pollutants whose quantity increases whatever the season.
During heat waves, the air conditioning of buildings and vehicles is an aggravating factor of this pollution ...
The vertical development of cities will accentuate this phenomenon while concentrating more inhabitants per m².

Where is the source of this statement? because I have no knowledge of this percentage
For pollution must look elsewhere and put trees (hardwood as some king of France who are still present have done) by cons I have not seen in our century many trees planted
I saw a lot of houses and buildings in large quantities

the surfaces of French forests are at their highest known level since the introduction of the forest code in 1827.

The only thing safe in the future. It is that there may chance that it conforms to our expectations ...
