Poland and the Baltics know they're next on Putin's list.

"Putin's list" is a dishonest meme, just like the "rules-based international order" that the Western nations supposedly embrace.

There is no such list, and there are no such rules. There is only deceitful propaganda used to justify geopolitical ambitions. Don't spread it.

AI is slowing down 1 month ago

They'd need to sell a sub to everyone in Europe and North America.

Yep. Every man, woman and child, and even then provided we include Russia, Mexico, Cuba, Haiti etc, and, out of desperation to get to 1.5 billion, Turkey, which is in Europe a little.

AI is slowing down 1 month ago

That's all true... however the point that Google will get just $1 billion per year from Apple for the AI service is still insightful.

If AI use via Apple represents 10% of the total that vaguely implies that the total AI market is worth around $10 billion per year (which admittedly seems a bit low), and if it is just 1% (which also seems low) then we get $100 billion per year upper-end estimate.

Which just is not enough to justify the current valuations of AI companies.

Iran would have to respond and thus would have to try to find a way to inflict ‘pain’ on the United States to force the United States to back off. But whereas Israel is in reach of some Iranian weapons, the United States is not.

This is too complacent for my liking. Every rusty trawler is a viable launch platform for Shahed type drones (operational range ~2500 km per Wikipedia). Nearly every US oil refinery and LNG terminal are on the coast. And then there are floating oil platforms (e.g.: https://en.wikipedia.org/wiki/Perdido_(oil_platform))

The article then says:

One can never know how well prepared an enemy is for something.

And:

And if I can reason this out, Iran – which has been planning for this exact thing for forty years certainly can.

I'll leave it here for y'all to ponder.

Urea prices 4 months ago

2022 was abnormally high, caused largely by the disruption of gas supplies to Western Europe after sanctions on Russian gas and the destruction of the Nordstream gas pipeline.

Urea prices 4 months ago

Yes, it is nothing like 2022 yet. But the concerning thing is that this may be just a beginning of a protracted event, plus the world, and especially Western Europe, is less resilient today to the disruptions in gas supply.

It's not as safe as flying

In France and Japan, HSR has had zero fatalities in the entire period of operation.

In China, HSR had AFAIR one fatal crash, with 40 fatalities. Per passenger-mile, Chinese HSR is twice as safe as US air travel.

Yes it does. Consider too that after kerosene whaling declined while world population, wealth and demand for lighting grew rapidly.

Also, kerosene for lanterns became a thing in 1846, not 1865 as claimed in the article, and by 1856 was already widespread. Wikipedia has this to say about its impact:

As kerosene production increased, whaling declined. The American whaling fleet, which had been steadily growing for 50 years, reached its all-time peak of 199 ships in 1858. By 1860, just two years later, the fleet had dropped to 167 ships. The Civil War cut into American whaling temporarily, but only 105 whaling ships returned to sea in 1866, the first full year of peace, and that number dwindled until only 39 American ships set out to hunt whales in 1876.[36] Kerosene, made first from coal and oil shale, then from petroleum, had largely taken over whaling's lucrative market in lamp oil.

The really big problem in open source intelligence has been for some time that data to support just about anything can be found. OSINT investigations start with a premise, look for data that supports the premise and rarely look for data that contradicts it.

Sometimes this is just sloppy methodology. Other times it is intentional.

Ooh, I love pedantry contests!

Let's go back to your opening comment which was something like "I thought methane was 80% hydrogen on a molar basis". Methane does not contain H2 molecules, it contains 4 atoms of hydrogen. Plus one atom of carbon, which would indeed make it 80% hydrogen on a molar basis.

If that does not convince you: note also that atomic carbon is also a very unstable, and will auto polymerize into one of its allotropes (eg. C60 - buckyballs). And yet we count carbon by the atom.

No, that is not right. The correct answer is "it depends", but let's run some indicative numbers on data for Boston:

On average and excluding the minority of routes with dedicated lanes (which may be best run on diesel), the Boston metro buses are in use for 6.6 hours per day, covering on average 53 miles.

A full size electric bus uses electricity at a rate of approx 2 kWhr/mile.

So, on average the bus would have around 17 hours to charge up with 106 kWhrs of juice, and this averages out to about 6.2 kW. On average.

However, the smart thing to do would be to charge the buses when the power costs the least, say between 10 pm and 8 am, so you'd need ~10 kW/bus, maybe ~1MW for the 100 bus fleet. Not difficult.

"Blue hydrogen" is commonly used for hydrogen produced from natural gas. If it is produced by steam reforming (most common), then the associated CO2 emissions are worse than if you just burn the natural gas directly.

"Green hydrogen" is usually hydrogen produced from water by electrolysis, using electricity from non-CO2 source, e.g. wind or electricity.
