This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.
Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.
We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:
-
Shaming.
-
Attempting to 'build consensus' or enforce ideological conformity.
-
Making sweeping generalizations to vilify a group you dislike.
-
Recruiting for a cause.
-
Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.
In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:
-
Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.
-
Be as precise and charitable as you can. Don't paraphrase unflatteringly.
-
Don't imply that someone said something they did not say, even if you think it follows from what they said.
-
Write like everyone is reading and you want them to be included in the discussion.
On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Notes -
Perhaps the "fundamental logic" at issue is geography.
Think about the viability of solar power for providing electricity to power air-conditioning in Arizona. Peak generation is around noon. The air is still heating up, so I guess that peak demand is around 2 or 3 pm. A bit of a mismatch. Curing that only needs two or three hours of storage. Overprovisioning might be cheaper than storage, there is still plenty of sunshine at 3 pm. The occasional cloudy days reduce the output of solar power plants, but those days are cooler reducing the power needed. It looks to me that this will work well and cheaply, and contribute to people saying that solar power is economically viable.
But I live in Scotland. Long days and some sun shine in summer. Short days and thick dark clouds in winter. The demand for power is for space heating, not air conditioning, and is in winter. I pay attention when I see reports of exciting new technologies for grid scale energy storage, but it all seems to be half day storage; keep the electricity on over night. The resource - summer sunshine - is six months out of synchronization with the requirement. Solar power, to generate electricity to run heat pumps to keep homes warm in Scotland is beyond the reach of current technology. Suitable grid scale storage doesn't exist, and huge overprovisioning would be fabulously expensive.
I favor nuclear power for Scotland. And people in Arizona should make their own choice based on how things really are in Arizona.
The anti-nuclear power argument seems to be "solar is cheap, therefore no nuclear". Prod a bit and it seems to be just missing the geographical factor. Putting geography in unsympathetically and it becomes "solar in cheap in certain circumstances, therefore no-one may have nuclear, and people in the wrong circumstance must freeze to death in winter."
Another contender for "fundamental logic" is that many technologies have an early dangerous stage.
The medieval cathedral builders had collapses. Ship stability wasn't properly understood leading to capsizes, even of giant prestige warships. Steam engines were indirectly dangerous because their high pressure boilers would explode. Railway trains had lots of disasters before signalling got sorted out. There is also an interesting technology progression with making braking systems fail safe, with the fail safe version of vacuum breaking getting displaced by Westinghouse's fail safe version of air brakes. The Tay Bridge disaster isn't really a railway story, it is about structural engineers not knowing about wind loading. Civil aviation started off really dangerous and is now very safe.
So it is odd to give up on nuclear power when you can look at the details of accidents, such as Chernobyl, and say: we don't build them like that any more, we are past the dangerous stage. We also understand key parts of the sociology. Nuclear power was cloakatively about providing electricity to civilians, but really about creating plutonium for nuclear weapons, so corners were cut on safety in the rush to Armageddon. Today we know about gotchas such as Wigner Energy and this time around is 100% about providing electrical power. I think that the safety issues really are in the past.
Overprovisioning solar power for peak demand is cost prohibitive in Texas, and you need storage anyways because of night time. Needless to say, overprovisioning for almost everwhere else is not going to happen.
Overpaneling is actually pretty cost-effective right now, even for home users. Until bidens tariffs hit this year, Chinese panels were just that cheap. The actual panels are a small fraction of system costs at this point, with the mounts, wiring, charger/inverter, and especially batteries being far more expensive. If you can rig up cheap ground mounts it makes sense to overpanel almost everywhere now.
People are doing neat stuff with parallel east-west strings sharing hardware, min-maxing DC transmission wiring to reduce system costs, finding cheap DC dump loads for clipped power, HV batteries, etc.
It doesn't solve the seasonal issue of course, but it's definitely economical, and making hr-scale battery systems even more viable.
