The economics of any power source is worse when they are not fully utilized. Wind curtailment which will be required for high penetration generation is one example.
You make it sound like they just built the plants in the wrong place.
No, I never hinted they were. They operate at very high capacity factors even in the very few places where very infrequent restrictions come in to play.
So, if a nuke plant is offline it's available, but if a wind tower if offline it isn't. Got it.
At/., accuracy and completeness isn't as important as the narrative.... Mr D from 63 (seriously, just a little ways down)
How Ironic.
If nuclear plants are generating power, as they were throughout the heat wave, then they are not offline. Your attempt at being a smart ass is pretty futile when I've provided links to charts showing the steady output of nuclear. Go ahead, profess your ignorance.
Germany produces 3 times more power from wind than from nuclear.
Moron...
Which is pretty clearly visible on your cherry picked graph.
Also, your statement is false. Wind only produced about 1.5 times nuclear last year and so far this year. But don't let facts get in the way of your complaint. https://www.energy-charts.de/e...
An interesting fact is that heat pumps (like home air conditioners, refrigerators, or nuclear power plants) are actually in the range of 200% to 600% efficient, apparently violating that wonderful law
No system and process in over 100% efficient. If you compare different properties of different processes, you aren't truly comparing efficiency. Heat pump efficiency is how efficient it is at moving heat. How much energy is put in, how much heat is moved. For electric heat, it is how much heat is transformed or released from a different energy form to heat.
Nuclear steam cycles are not heat pumps because the heat energy is primarily converted to mechanical energy. Yes, there are heat moving elements of the steam cycle, which are similar in principle to heat pump cycles.

You miss the point. Germany has stupidly shut down nuclear plants, but nuclear is still available when needed, unlike wind. One chooses charts to illustrate points, I chose one illustrating what is happening during a heat wave. Sorry you don't like that.
For the heat wave weeks, nuclear generated more than wind. Even with 58 GW installed wind vs 9.5 GW installed nuclear.
Poor design. All over the world there are nuclear plants operating just fine in hot tropical and subtropical climates, including the USA. Never has been a problem. So the Euros are doing something wrong with their designs.
Almost all the European nukes are running just fine, full output. Only a few have cut back due to discharge heat limits.
From TFA, the reason why the reactors were shut down (which wasn't included in the summary) is:
Europe's heatwave, however, hasn't just increased air temperatures but also water temperatures. Regulations protecting wildlife mean that the usual water sources drawn on by nuclear plants cannot always be used for cooling, leading to shutdowns. It's not the first time this has happened: Heatwaves forced nuclear shutdowns or curtailments across Europe in 2003, 2006, and 2015.
Yeah, I know that reading TFA is no longer cool on Slashdot, but someone has to help out the editors.:P
At/., accuracy and completeness isn't as important as the narrative.
The problem with climate change isn't so much as our planet breaking but everything we depend on breaking. Somewhat wacky that nuclear reactors aren't designed to handle this heat but then again I would have never imagined the crazy kind of temperatures Europe has skyrocketed up to. So one has to wonder, what other stuff is going to break?
Nuclear reactors can handle high temps just fine. Only in places where there is limited cooling water and cooling releases rise above local environmental limits are they cut back.
The first thing I thought when I heard this story was that it would have to be a large drone to carry much explosive power, and would need to get quite close to the person to pose much danger. Not something you'd be surprised by. Something definitely didn't make sense.
The media is in too much of a hurry to report than to think about it.
Zheng's attorney disputed the allegations, saying Zheng "transmitted information on his own patents to himself and to no one else."
My experience with giant corporations is that I sign away the rights to the things I invent for them as a condition of employment. "My" patents are at home, with documentation that they were all done on my own time, using my own equipment. And even that may be subject to litigation if the patents fall into the same type of things that I develop at work.
That's been my experience as well. There are also rules about handling proprietary information in general.
China is waging an all out war on the West, stealing every bit of IP it possibly can, while militarizing the South China Sea as part of its "One belt, one road" initiative, along with its 2025 and 2050 roadmap. It's about time America started recognizing that and responded appropriately.
No, its Russia. Let's not take our eye off the ball. Russia is the enemy! Why do you think the news talks about Russia so much more than China? Get with the program.
Dunno about you, but my corporate gym doesn't have a sauna. Nor do the public schools, the storefront gyms or other facilities the proles commonly use. Are you sure these findings aren't just looking at wealthy white guys somewhat interested in health vs. the great unwashed cheetoh-eating masses?
Looks like the meta-analysis didn't mention any factor analysis, which should have been an obvious thing to do in a correlation-based study. Of course, the reason for that lack of analysis could be that the studied papers themselves avoided factor analysis (which seems to be the case at least for the first five or so paper abstracts that I scanned).
It certainly would help if they just included one sentence in the abstract that other health habits were accounted for (or not). Its a big peeve of mine how often those statements are not made clearly in meta studies, and when not I tend to assume they were not accounted for.

It's a review paper, so in some cases yes, in other cases probably not.
But I think the hypothesis makes sense, a sauna stresses the system and is essentially a kind of exercise, a style of exercise you're going to have trouble finding elsewhere.
In general, exercise is good for your health.
Correlation makes sense. If regular sauna users exercise more and eat better on average than non-sauna users, they'll be healthier. I would expect the study accounted for such, but the linked summary doesn't mention those possibly factors.
If they fill this model with data they don't have, for the all the areas where there is going to be a fire, they might be able to better predict its behavior.
They are for FB. But why they need to try to tie everything to Russia is beyond me. Why don't we care about all the other countries and/or intenational groups or individuals that are also attempting the same stuff. Why not a single story that talks about anyone but Russia?
The saddest part of all of this is the idea that people are forming political opinions based on what they read on FB. That to me is the biggest problem we have.

Korea is even started up nukes that were scheduled to be down for maintenance to help during their heat wave.

There's rivers in the US where power plants have raised the water temperature 20 degrees and essentially displaced the entire habitat.
An exaggeration. But do you know how much habitat Hydro power has displaced by comparison?

But they were available. If you look deeper than headlines, you might realize such. I even provided links to make it easy for folks like you.

In Germany, recently, nuclear was a steady producer while wind was barely producing.

It's likely because we have a president who may have gotten help getting elected from Russia.
Got elected 'from' Russia? Better tell CNN about that.

I wonder if the headline should have added "except in China".
There's a good reason why Google doesn't want to go down the three notch road;

Because there is evidence that points to Russia.
Not in this case. They said they have no clue who is doing it.
