Putin had already stopped supplying gas through the pipelines, blowing them up did not change anything for him. But it absolutely did change the moves that would be available to any post-Putin government in Moscow. Blowing up the pipelines instantly de-funded any upcoming revolution. Add a "plausible culpability" mock attack by Ukrainians who likely actually believed that their handlers were on the Ukrainian side and not Russia to foster division in the west and you have a clear "why wouldn't Russia do it?" situation.
Matches an observation of mine that skips the prison lingo: lack of the concept of friendship without any power gradient that would make it more like a liege/vassal relation than like an alliance between equals. I wonder if that might be an echo of communism, which likely claimed all elements in the Russian language that were related to equal relations and effectively burned them for regular use?
The problem with that last paragraph is that through almost all those regime changes (I guess the time between the Soviet collapse and Putin's rise may have been an exception), Russia has continued a strategy of systematic displacement for accelerated "russification". Those provinces effectively do not exist, they don't have enough population that identifies with the region more than with the empire.
If you force a Tatar to somewhere close to the Chinese border he will be perceived as "Russian" by the indigenous community, and their rejection will eventually make him identify as "Russian" himself, to bond with his peer displacees from other corners of the empire, and with locals who accept the empire. The exact same mechanism works in all directions, e.g. when some of those locals are displaced to somewhere near the Finnish border. The most important weapon of the Russian empire isn't the tank or the AK-47 or hard winters or sheer distance or vast amounts of mineral resources, it's industrial scale deportation for eradication of regional identity.
Because the ruling gang has plenty of prosperity in their lives and "us vs the rest of the world" is the only way they know to keep the other 140+ million content with the few scraps they get. The more violent attitude they keep up against the rest of the world the less violent oppression they need at home to stay in power.
The same wealth disparity does not exist in the west. Travel 100km out of Moscow and compare how people live to the same distance from Paris. Then go to the Russian Far East. It’s overtly that not been seen in the west since the 1950s and WWII reconstruction.
Is that "regulatory" the problem or is it the solution? We'll know more 20 years from now, looking back at fire incident statistics.
(yes, I'm leaving it open if regulation makes a difference or not - for all we know it could even make a negative difference, helping companies that are better at regulation than at safety. But if I had to bet, I know where my money would be)
GP wasn't talking about discharge, losing a little energy, they were talking about wear and tear, as in the batteries aging fast while in a highly charged state.
Battery recycling still hasn't really left the "we can do it in a lab" stage.
I wonder how much Google is factoring in the implicit cooling cycle? Because any pressurized gas energy storage is either including some advanced heat storage or is just venting the heat created during compression (the ancient Huntorf facility in Germany is infamous for that, super wasteful)
Usually you want to keep the heat and put it back into the compression medium during decompression and hope that losses from the heat storage aren't too big, but when you have a cooling use case nearby, you can use that low intensity heat to compensate heat storage losses, or even overcompensate. When you consider how much of the power input of a datacenter is typically used for cooling, compressed gas storage could be useful even if there was zero electric recovery (just time-shifting the power consumption for cooling to a time with better energy availability)
I'm sort of thinking out loud here but could you have two batteries running simultaneously but on opposite cycles, so while one is cooling the other is heating? Obviously it wouldn't be 100% efficient but it might reduce some wasted energy.
The heat and cold are created by the compressing or decompressing the CO2 (our any other gas). If one battery is heating while the other needs heat that would imply that one is charging while the other discharges, which is rarely useful in normal operation
If Google is colocating these with data centers, even low-grade heat that would otherwise be a loss could still be useful, or at least reduce how much active cooling the DC needs
Isn't this effectively neutral over time? Heat generated during compression, lost during decompression, so basically using the air as a heat storage medium?
I think what he's saying is you can boost efficiency if you compress a cooler gas. So if you could capture the "cold" that you get from discharging the device, and use it to pre-cool the air for the next cycle (or use it for the data centers cooling system) , it would be much more efficient.
Cooling is rarely done in any other way than compressing a gas, allowing the heat to dissipate and then allowing it to decompress again. You don't want to compress a gas to cool another gas about to be compressed. What reasonably advanced compressed gas storage systems do is capture and store the heat that gets created during compression and feed it back during decompression. This gives the same efficiency difference as compressing some magically pre-cooled gas would do, only on the discharge side.
So far so good, just the old thermodynamics. It gets interesting when you have a cooling use case anyways: then you can skip on some of the decompression recovery and use the "cold" from decompression directly, to cool down something that needs cooling, without going the extra way of converting back to electricity and then sending the electricity recovered into a compressor setup for "creating cold". Bonus points if you also have a use case for the heat you did not use in reconversion to electricity, but chances are between losses during storage and heating some the gas back some amount beyond neutral you won't have much spare heat anyways.
Yes. A large radiator would handle both. I assume they just store the heat because hot water will be a lot more efficient at reheating the co2 than night time air and a pool with an insulated cover is not hard to construct.
> It will be interesting to see how they make this arrangement approachable for Arduino’s audience which generally expects ease of use to be a high priority.
Would not be surprised to see both approaches to developing only for one of the two systems: programming the MCU and deploying some ready-made stuff to the big Qualcomm chip, like a stacking a shield on top of the Uno only that the shield is software-defined (providing some compute service), and running some ready-made interface abstraction on the MCU, running everything individually programmed on the powerful Linux chip. Likely within some form of JVM or a Python runtime, or node.
So, even more people out on the streets desperately trying to get their slice of survival by being sexually available to the equity lords? Because what else will there be?
Similar thoughts crossed my mind as well. But then there's the repopulation with a species that can be traced from Asia. The pre-gap felines just aren't part of the post-gap set. If some were descendants of some endemic low-fossilization branch, chances are they'd be connected across the gap through similarities.
