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 -
While I'm inclined to agree with shamilton's take here that high renewable mix makes nuclear less likely to be economically feasible, not more, I do wonder if there's a play to stick a reactor in the pilbara to run an electric arc furnace. No one would care out there and it helps cut the primary fp knot of Australia being the only producer of iron ore worth talking about and China being the only buyer.
Nuclear reactors rely on abundant fresh water for cooling. Australia's geography favors nuclear power plants built along the coastline of the Eastern states.
there are a few rivers near port hedland which has rail connections to the major pilbara ore mines

Does it actually have to be fresh water?
Nevermind. I was wrong. Seawater also works. There are even power plants that are air-cooled using giant radiators. But it's definitely disadvantageous to build a nuclear power plant in the middle of a desert with no abundant source of water.
There's one in the US south-west that cools by evaporating all the local sewage water, but that doesn't exactly scale well.
Higher reactor temps will eventually make the cold side less important. Delta-Ts on current reactors are at "1800s steam engine" level, terrible thermal efficiency. The Chinese are developing high temp air-cooled reactors for their northern desert regions for that reason, maybe the ozzies could piggyback off that.
All that said eastern Australia is in an amazing position for HVDC solar transmission from the deserts, which will undermine nuclear economics. Unless they can't be built because of some sacred spraypaint can worshipped by the local tribes.

Well probably, yes. And I'd assume that a hot desert(like 90% of Australia's territory) is not a great place for air cooling. But is there any reason you can't build reactors on the coast, where the vast majority of Australians actually live, or at least near enough to it to pipe seawater in?
Yeah even if the coast is relatively dense by Australian standards there's still huge chunks of the Eastern coastline that's essentially undeveloped. Latrobe-Gippsland has a large coal mining presence already and about 6.5 people per square KM (which is concentrated into a few urban areas)
