I don’t understand how an electric car can be called clean with zero emissions. How do we make that electricity?
Even hydrogen requires electricity for water electrolysis.
Currently, hydrogen is also made from fossil fuels (mainly methane?).
Electric cars and hydrogen cars may be zero-emission vehicles in themselves, but where they are powered, carbon dioxide is produced.
By the way, we breathe and release 1kg of carbon dioxide per day, 365kg per year. It seems that about 10% of the world’s total carbon dioxide emissions are due to human respiration.Plus, we eat meat. The production of meat also releases carbon dioxide. Eating plants that absorb carbon dioxide is also a negative factor.
They say that if we replace fossil fuels with biofuels, it will be carbon neutral, but that is also a lie. Plants grow by absorbing carbon dioxide. The carbon dioxide gas that comes out of burning the alcohol produced by the plant was originally absorbed by the plant, so there is no need to think about increasing or decreasing it. Alcohol itself may be true.
However, it takes energy to cultivate, fertilize, ferment, and distill farmland.
In the end, I guess it’s no good with carbon dioxide.
It would be the ultimate zero-emission for the earth to have converted plants into coal at high temperature and pressure over a long period of time.
Recently, I read a paper on the use of iron-aluminum composite oxide catalysts and microwaves to extract hydrogen from polymers such as polyethylene, and the carbon skeleton becomes carbon nanotubes (CNTs). It is a very interesting carbon fixation method.
If there is plenty of energy, there are many things that can be done, and there are many ways to combat global warming. Germany, France, and other countries have also turned the tide in the direction of relying on nuclear power.
In Japan, there is a very high level of aversion to nuclear energy in Hiroshima, Nagasaki, and Fukushima.
When the Fukushima accident happened, I once proposed the following. “Order 100 nuclear submarines from the US. We will berth them where energy is needed and generate power. When the tsunami hits, it will run offshore.
If we don’t have space for a location in an earthquake-prone country, and we emotionally don’t want a fixed facility to come, I thought the only option would be a mobile one.
The Senkaku Islands and Takeshima will be used as mooring bases for such submarines, to be operated jointly by Japan, China and South Korea.
Then my friend warned me that Japanese people’s sense of avoidance is still very high, so if I said that, I would get fired.
Yeah. There is a way to achieve carbon neutrality without nuclear energy. Just remember the Edo period when the country was closed off. At that time, the population was 10 million, nowadays, maybe 30 million people can be isolated.
At that time, we should all drink panda pee.
Pandas are carnivores because they are members of the bear family, but they can eat and digest bamboo grass.
Intestinal bacteria break down bamboos and turn them into nutrients.
When pandas give birth to their young, they are made to drink their parents’ pee, which feeds this bacteria into the intestines of their young.
If we can immobilize this bacteria in the human gut, we may be able to use cellulose as a source of nutrition.
If nothing is decided at this point, we will naturally return to the Edo period.
Black or white, front or back, ruling party or opposition?
We will continue to be unable to decide anything until we stop.
In this respect, I envy China.
It’s still better than a popular government that just chooses the answer by majority vote.
I don’t like nuclear power plants, I don’t like the Edo period, and I don’t like panda pee.
If we just say so, the government or scientists will do something about it.
Yeah. Believe and you will be saved.
