layer?
- The example of cars, that was very easy to understand.

4 November, Comments and Questions
- The difference of cause why people passed away in each big
earthquake in Japan was interesting information for me!
- It was very shocking fast that Kanazawa has few seconds
before having secondary wave.
11 November, Comments and Questions
- My hometown is located in Nankai area, so I have learned
about the earthquake since I was a child. But today, I can have a deeper understanding
of the earthquake and change my mind of the topic more and more by today's
lecture.

come Japan? There has no possibility to go Korea - China side?

- I am looking forward to taking your next lesson.
- Why does oil exist particularly in middle eastern area?
- It is ______ that methane hydrate is buried in the sea around
Japan, but is it possible to actually mine it?
- It is interesting to know that the UK cut all trees for
charcoal. That's explain why there are only few national parks today.
16 December, Comments and Questions
- I didn't know that water coming means the end of oil at
the point.
- Is water that comes out from under oil clear? *solved by
your additional explanation, thank you!
- I can't imagine the daily life without oil and so on.
- オイルシェールオイルは取るのが大変だと感じましたが,石油が不足するのを見越して掘られているのですか.それともそれにしかない利点があるのですか?
- Can people find oil or other resources around Japan with
good quality?
23 December, Comments and Questions
- Are the rivers in Japan suitable for hydropower?
- Is there a possibility that until these fuels like coal,
gas, oil so on, we can not find the way to generate energy without fossil
fuels?
- It seems contradictory to popularize electric vehicles even
though, especially in Japan, we rely on thermal power generation.
- Riding bicycle is good for environment, your body, and sometimes
even could be faster than car. However, now I can't imagine life without a
car in this terrible climate like Kanazawa.
- In the lecture, one of the disadvantage of solar energy
is that its cost is high, but it is also because solar energy is compact and
have a simple structure, solar energy is low cost.(講義の中で,ソーラー発電は費用が高いといわれてましたが,後半の説明で費用が安いとも言われてました.どの点の費用が高く,又安いのでしょうか)
20 January, Comments and Questions
- By doing this research, I realized advantages and disadvantages
of energy resources are quite similar. They are expensive to install, but
clean and good for nature. Therefore, if we look at the long term, I would
say renewable energy is better and has lots of potentials?
- Since environmental problems are becoming more and more
serious, renewable energy is attracting attention. However, I feel the initial
investment of renewable energy is expensive so that the countries which can
use them are limited. I felt it would be difficult for developing countries
to use them. In addition, many renewable energies don't require the impart
of fuels like coal and petroleum, so I thought they can be solve the energy
shortage in developing countries.
- I suggest that using thunder and lightning as energy. I
think it has great potential.
- I doubt whether it is really possible to convert almost
energy to renewable energy in the future. And if it is possible, which energy
became a main resource and how technological development is required.
- Electric vehicles are widespread not only in Japan but around
the world, but since thermal power generation is currently the mainstream
in Japan, even if electric vehicles become widespread, I think it is meaningless
unless renewable energy is used.
27 January, Comments and Questions
- Can the method of "carbon neutral" decrease the amount of
CO2 in atmosphere, or it can only prevent CO2 from increasing?
3 February, Comments and Questions
- Speaking of Venzia, there was a memorable news that the
water of the region became clear because of the pandemic, tourism and people's
movement declined.
- Land subsidence is more likely occur in developing countries,
and I think it would have a bigger impact on people in those countries.
- I have heard that we can't build a subway if there is a
risk of land subsidence, is that true
10 February, Comments and Questions
- Humans have evolved from monkeys but I wonder why monkeys
remain monkeys without further evolution.
- 人間の種類は1つだけとありましたが,人種はどう位置づけられるのかくわしくきになりました.
