Friday Fun Thread for November 4, 2022

Be advised; this thread is not for serious in depth discussion of weighty topics (we have a link for that), this thread is not for anything Culture War related. This thread is for Fun. You got jokes? Share 'em. You got silly questions? Ask 'em.

They're seriously glossing over the difficulty and expense of making compact steam turbines for use at sea. For one thing turbine halls are, what, twice the size of the reactor building itself? They've squeezed them into a much smaller space in the diagrams. I'll post it on Navalgazing to see what they think.

It's pretty common for nuclear concepts from the Good Idea Fairy to ignore the non-nuclear stuff.

Luckily there are still naval steam turbines made, but buying gear designed for the US navy isn't going to be easy or cheap (forget buying them on Alibaba lol), and I'm not sure what modifications would be needed for running them off commercial boilers using low-enrichment fuel rather than the 94% bomb-grade stuff military reactors use. The pressures are going to be different, I imagine.

And rather than transmission, I'd be worried about the costs of designing and maintaining very compact transformer equipment rated for use at sea. Nobody makes that afaik. (Edit: I was wrong about this, as there are power barges in use, but I don't know how wrong. Looking up what they cost would tell you a lot about how practical a nuclear one is.)

At least there's precedent: back in the 30s the US moored some of its turbo-electric carriers off California to provide power. This is literally just changing the heat source.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
