If you use a heat pump in winter you do actually make outside colder. So there is that analog.

It's not the magnitude of demand that affects price - it's the price elasticity - the demand and supply curves matter. Demand for petroleum (e.g. gas, etc.) is very stiff - so small changes in supply can have large impacts on price.

While I'm sure some of that does occur some places in the region, my experience in the Utah/Idaho region is very much the opposite. Friendly and very merit oriented work environments.

Depending on who you talk to and your definitions, nuclear is generally considered dispatchable. The only definitively non-dispatchable sources are e.g. wind and solar where they cannot guarantee power levels and availability during the dispatching window. It is a bit of a spectrum - some sources (i.e. nat gas plants) are considered highly dispatchable because they can be spun up and down and adjust power levels very quickly (i.e. load following).

Global supply chain problems. Inflation problems. China still doing rolling lockdowns. Geopolitical conflicts. Ukraine. China-Taiwan. Off the heels of a not unlikely a lab evolved virus pandemic. Extreme political polarization in the U.S. Increasing anxiety and other mental health problems in youth. I'm going to go with very worried. But maybe I'm just becoming an old cynical curmudgeon.

It's not really overloading. it is associative:

    2*time.Hour+1*time.second == time.Second+time.Hour*2

No they are technically correct. In the reactor world "shut down" explicitly and specifically refers to chain-reaction-running mode. The reactors do still require active cooling for several days+ to avoid plant damage scenarios. Several comments on this page seem to not have a clear understanding of this difference.

Once the chain reaction is shut down - there is basically no way for the reactor to come alive (chain-reaction-wise) again on its own - not even if it's being bombed, shelled, etc. And run-away super(prompt)critical reactions are not even possible with this reactor design. These reactors are water-moderated - which means that water is used to slow down neutrons to increase their reaction probability. As the reactor heats up, the water gets less dense (even if it is still a liquid) making it a less effective moderator - this density decrease is enough to passively/automatically keep the reactor in a shut-down state. Residual decay heat from radioactivity of the fission byproducts post-shutdown is enough to damage the reactor internals for several days - hence the need for active cooling post-shutdown.

I've seen lots of crazy-exaggerated news reporting on how "bad" or "dangerous" this entire situation could be. It's not good, but neither is the war in Ukraine. It's not even remotely possible for this to be anything like Chernobyl, and I think unlikely to be nearly as bad as Fukushima (which in the grand scheme of the Tsunami - wasn't really that bad). In the war context, I don't think this nuclear plant situation is particularly notable beyond it providing a large fraction of Ukraine's power.

I am a nuclear engineer FWIW.

Why is twitter not letting people see and talk about this? What happened to discourse? I'm completely unsurprised that a tweet that shows how extreme our covid discourse/mitigations have become has been removed/deleted.

I agree it's absurd - which is why I wasn't sure why it sounded like you were making it. So since we established natural immunity is superior - why is it being ignored? Apparently it's not part of _the_ science.

But what about people that have already engaged and benefited from that risk? For many of those people, the vaccine risk is not so negligible compared to the additional benefit they gain from any (much smaller) immune boost they might get. Also, how is policy making "following _the_ science" if it doesn't even acknowledge the superiority of natural immunity. The least they could do is own their disregard and say - we're ignoring some science for [reasons] instead of simply demonizing a large fraction of the population as bigoted selfish backward uneducated scum - which is my interpretation of POTUS declaring war on 20% of Americans - a so called "pandemic of the unvaccinated" in his own words (or whoever wrote the speech).

You mean the shots that provide sterilizing immunity for diseases that have orders of magnitude higher mortality rates for children and healthy people? None of which is true with COVID - and anyone that disagrees can just look up the stats on the CDCs website and read about sterilizing immunity on wikipedia.

Yes - infected+vaccinated is more protected than infected. But infected is way more protected than vaccinated only. If your position is that everyone should meet the highest standard of infected+vaccinated - which is only marginally better than just being infected - then we should be mandating mandatory covid infection. But if your position is that vaccination alone provides acceptable protection, then infection alone already far far surpasses that in both lasting immunity and total efficacy.

[edit] Here is an excerpt from their conclusion:

"This study demonstrated that natural immunity confers longer lasting and stronger protection against infection, symptomatic disease and hospitalization caused by the Delta variant of SARS-CoV-2, compared to the BNT162b2 two-dose vaccine-induced immunity."

From my evaluation and research, nearly all the economic damage is being caused by said mitigations - not the virus or pandemic itself. So... stop doing the things that damage the economy? People want to work. People want to travel. People want to play. Let. Them. Do. It. A few are fearful and want to hide - that's fine too.

This is actually false and contradicts findings from several very reputable and large studies. See e.g. https://www.medrxiv.org/content/10.1101/2021.08.24.21262415v...

That's a pretty poor analogy. Nails are often the right and often the wrong tool for different circumstances. And there are different kinds of nails. Lots of carpenters have preferences for what types of hardware they use - based on their own experience and that of experience from others. And even if I disagreed with a carpenter on what tools were right for any given particular circumstance, it would be silly to try to micromanage them doing their job - just let them do their work!

"because it's inconvenient" seems like a pretty poor precedent to set for governments mandating (unnecessary) medical procedures.

Where is the discussion about the fact that a very large fraction of these employees likely already had far superior natural immunity - which is provable. So they were fired for refusing to undergo what amounts to an unnecessary medical procedure. And these vaccines are non-sterilizing - so it's not like other vaccinations that are routinely required in other public health contexts.

Funny - I'm sure many people could argue the same about democrats - they're the ones firing people for not undergoing unnecessary medical procedures and coordinating with multinational companies on censorship guidance.

You are not alone. The authoritarian threat and government overreach problems are IMO orders of magnitude more important and concerning than the virus. I will almost certainly be taking a stand and be terminated by my employer over this within the next few weeks.
