A french association suggests this approach: https://fr.wikipedia.org/wiki/Compte_carbone [in french]

Where does the source you refered to provide evidence of hybrid war?

The biggest fire in France has most likely accidental root cause (https://fr.wikipedia.org/wiki/Feux_de_for%C3%AAt_de_2026_en_...)

I think that is the root of the problem, there is no one magick trick. We need to attack it from many angles, as each of them is weighting only a couple of percents. Reduce air traffic and reduce meat consumption and reduce fossil fuel for transportation and reduce deforestation...

I had similar idea, a tool to model the economy of a country. The idea would be to give to every one a simple tool to groundcheck political programms before voting. The economy is complex, there is no simple solution to a complex problem, only trade offs. But you need to see the effect of these trade offs before making a decision and elect one or another politician.

I like to think of llms as seamless plagiarism machines.

And in the mean time, western europe is having its second heat wave even before summer starts.

Not having to install is huge avantage in corporate environmeent where user can't install nor run binaries that have not been approved by IT dept.

There is a french company (https://unseenlabs.com/fr/) that specializes in tracking ship at sea through observing their RF emission from space. Cool tech. I'm pretty sure their main clients are not all civil...

Yes that's sound weird but this is to make sure gas peaker plants which by definition run only a fraction of time can be profitable and be built.

Diesel engines are also more efficient.

Nearly 40% of shipping volume worldwide is moving fossil fuels (coal, oil, gaz). The easiest way to reduce drastically shipping emission is reducing usage of fossil fuels...

And electric motors are way more efficient than ICE motors that hardly reach 40% efficiency.

They didn't wait for their parents to tell - they figured out with their friends.

I can confirm. I didn't know the story and I picked up that book randomly in a book store a couple years ago. I loved it.

Very neat! I'm hydrodynamics by background and I wondered a long time ago why this kind of approach was not used as I always found ocean waves to look awful in movies. Once you describe ocean sea state in frequency domain, it is quite easy to give to floating objects like ships realistic motions using what we called RAO in this field (linear operator). You can also model sea disturbance (diffracted and radiated waves) caused by an object in a similar fashion.

I visited conservatoire des arts et metiers museum in Paris a couple years ago. It is full of fascinating scientific devices from the past. Among then was the timbre analyser. I was blown away. A purely analogic spectrum analyser.

In France at least, more and more stations require pre-paying at the counter, especially stations in big cities.

The problem with this line of thinking in my opinion is that we have 30x3% problems... sure individually they would not make a difference but we need to act on all front.

Cut off wind speed is typically around 25m/s steady, so almost 100km/h. Beyond that indeed they stop producing.

A very nice writing about that concept where more wind power drives price down: https://jeromeaparis.substack.com/p/the-cost-of-wind-the-pri...

Beware that the £70 MWh is as per 2012 price, as were the previous £44 of AR5. So effectively close to £100MWh corrected for inflation.

Has HFT any value for the society in general?

I m wondering what sort of cycles they are referring to. I would expect one very big full pressure cycle when slowly going down to seabed and returning up to surface. Unless they do hundreds of descent with the same hull...

Although I don't necessarily share your tone, I share some of your ideas.

https://www.lowtechmagazine.com/2021/05/how-to-design-a-sail... is worth reading. Basically container ships are incredibly energy efficient. If we want to go back to sailing ships for cargo, then we need to massively scale down global exchanges.

Now on a positive note, if we find some devices, easy to operate, low cost and that can save few percent of fuel (being fossile or green), then that could still be useful.

What is the order of magnitude of the wind load generated on one single wing?

Did you check https://farwind-energy.com/fr/ ? That's exactly what they are trying to do !

I would really like to see numbers; as elegant as it appears, I don't really think it can be very efficient.

I would think this would equally affect both boys and girls.

"There is a rapidly closing window of opportunity to secure a liveable and sustainable future for all (very high confidence)"

Given how each word is carefully weighted in their report, this sounds a bit scary to me.
