This is a different issue. This is discussing the situation of gathering power from the edge of the grid (e.g. home solar) and bringing it up into the central grid, rather than as now having power distributed from the power stations at the centre of the grid out.

Note that it's talking about substations particularly the ones that provide to domestic consumers.

I'm talking only about high voltage transmission, not about local grid to (and potentially from) consumer transmission. In high voltage transmission the actual cost of the metal conductors and the transmission link massively dominates the other components and so, whilst there are some unidirectional HVDC links, even there they are rare.

I was going to tell you that ERCOT is living in the stone age of electricity transmission because I remembered that you were mostly right. However luckily I actually checked because it turns out that ERCOT has turned on dynamic pricing and now works the way I said and no longer as you just described. You would not have been wrong 10 years ago, but this has changed.

You are both very much missing the point. Almost all power usage should be directly balanced by generation. When demand goes very high, prices go very high, all available generation runs at whatever level it can and demand reduces, through reducing most commercial use, until things match. When generation goes high, prices reduce, all available demand runs and most generation that can be forced off the grid is (typically with the exception of nuclear and some home solar, though that is voltage limited).

What the storage does is takes the lowest possible point of price, uses lots of electricity during it and supports the grid price keeping more generators profitable, then takes the highest price and sells into it, keeping more uses reasonable. A key point here is that almost all electricity transmission connections are bi-directional and the cost of making them so is a trivial addition on uni-directional transmission.

By putting some demand (the data centre) together with some storage (the batteries) together with some generation (wind or solar plants) then at the moments that really matter each of the elements benefit. Importantly, the batteries, and especially the renewable plant get to be overbuilt for the data center because they can also satisfy other needs. The transmission gets to share costs between incoming power for the data center (when there's no sun) and outgoing power from the panels (when there's lots of sun). When there's lots of power and lots of demand, the grid becomes transmission limited. At that point the data center us using excess power from the solar panels that wouldn't otherwise fit through the transmission and so it gets cheaper energy and the reneable generator gets more money.

It's a win, win, win situation even though you never run the whole data center for a long time on just the batteries.

It would be highly funny if a Chinese action designed to destroy America was actually what slowed things down a little and saved the US economy. Definitely it's a good discussion to have.

However, the thing about mindlessly saying "they're right" is that they will be targeting the best data centers and ignoring the worst. Data centers need to be built where there's an excess of renewable energy and be used to subsidize huge battery build ups in those places. Done right, putting demand in the right places pays for power that can be used for everyone. Instead some people are proposing that they generate their own power - often using fossil fuels.

Even if China has a point, and the best propaganda always has some truth behind it, that doesn't mean that what they are doing is helpful.

I'd say this looks 100% lucky. This could have been bought out by a company that made it proprietary. It could have turned out that DuckDB became an open core / key features proprietary nightmare like so many companies that decide they have to monetize. Instead it's likely that this will remain available and free and that contributors that wrote parts of it will still get useful credit and be able to continuing developing.

There can be much worse consequences of failing to make sure the software you are contributing to has a decent copyleft license.

Unfortunately GrapheneOS needs a bunch of hardware support to do the security they do so your baseline model isn't going to hack it. However, if you get a second hand one later it'll be cheaper. These phones are going to have a better resale value for sure. Even if you are just planning to run Android and want this level then probably a reason for choosing Motorola anyway.

Hmm. Probably originally implemented to enable Kremlin surveillance of Russians (in Russia), but there was no reason to remove the surveillance back door for the export version/

The Kremlin would just get the installers to give them the direct access. No need with getting special complex software features written. Also, historically their crypto stuff has not been bad and has been paranoid so this is unlikely to be official. This is either done by private people associated with the company or, more likely, done by Russia with the speculative hope that they get installed somewhere interesting abroad. Likely there are hundreds of these cameras in countries all over the world and if they can do number plate recognition or be fed into a system which can then they can be used to track dissidents and so on.

There doesn't seem to be as much money in green energy than there is in, lets say, oil.

It's a bit more specific. The money in oil goes to a specific group of, typically quite corrupt (because it involves land purchase and government permits) businessmen. There is less money in renewables (which is why they are cheaper for the consumer) however the money goes either to sophisticated engineering such as turbine and solar panel production or to the local owners of the solar systems.

That means that where oil tends to damage the local economy (look at very oil rich countries, like Venezuela and Nigeria - exception being Norrway), renewable generation can be very much a positive.

You aren't exchanging keys, you are generating fresh ones. The information you exchange is the entangled state, but even if it's intercepted it's not an actual bitstream so Eve gets nothing. The entangled state is then distributed at less than light speed. Now you come to use the state and "generate" the key. At this point the two different entangled particles both give you the same number instantly depending how you measure them, but there's nothing traveling in between so nothing to intercept.

So no idea what you argue about

Not sure we really are arguing much. More like violent agreement.

So since 3 years, we are consistently around 60% production of electricity by renewables.

Germany is not under the top 10 yet, but we are working on it.

This, IMHO contrasts with the earlier comment

We switched to renewables ... you must be living under a rock.

I'd say you are switching and that the nuclear turn off should have been delayed so that the reliance on natural gas during the changeover was lessened compared to what it currently is. I'd also say that this is the time for saying "there is a war on", overriding some farmers concerns and then settling on full compensation once Russia is completely and soundly defeated. The Norwegian and American gas which Germany is using now could be beneficially delivered to the new Hungarian government instead, allowing them to switch off their reliance on gas.

In the end, though, it's a glass 60% full vs 40% empty story. Without German determination and taking responsibility Russia would have had much more money than they already have. The people who blew up Nord Stream should be treated as European heroes, however. Merkel's record should be disowned, and Schröder considered for treatment as a traitor.

My understanding is that you also cannot use entanglement for communication at all (for example, by separating entangled particles and relaying state information between them).

Careful. You can't communicate information with it, but it could be useful for securing communication. If it was done right and both sides know that they are going to simultaneously measure a series of entangled states then they both get a shared data stream that they know nobody else has access to and can use for encrypting other data that has been transferred at normal light speed or below.

In real life, however, when systems based on this were examined it turned out that they mostly weren't done right and you would be better off using conventional encryption, probably some quantum resistant form. You definitely want any such system to have been audited by competent conventional security people.
