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.

This is really cool. A (pretty good brand) 600W inverter can actually run my chest freezer. It could easily run two of them if I could design a simple startup interlock switch (or trust the inverter's auto-restart from fault to handle the occasional simultaneous startup)

People always complain about freezers tripping 1500W inverters, but newer compressor motors don't have nearly as high a starting surge as the old ones.

Pity it can't run my shitty universal motor garden tools as well, or I'd rig up a backpack for it.

How are you feeding the inverter?

And what are these universal motor garden tools?

Cheap 1200wh lifepo4 battery charged with a 40a power supply. Can run for a couple of days followed by a few hrs of generator recharging, instead of idling it all the time or letting the freezer half-defrost.
A few hundred watts of solar would keep it charged even in winter, but I'd need to run a long transmission line to my shady clearing. Impractical with a low volt array.

The garden tool motors are those really cheap things with the sparky carbon brushes.
Very low efficiency and huge inrush: I have a ".5hp" pump (375w) that pulls the amp equiv of 3000w at startup. (Not sure how much is real vs apparent power, but to an inverter amps are amps)
Still learning electric engine theory to understand the different types.

May I ask why you're doing all this? Is this a prepper style setup you're creating on a back lot in the woods somewhere?

I don't want thousands of dollars of meat to spoil when the power goes out? And also like having Internet. And also it's fun?

Fair. I also have this setup, with one dual generator and starlink. I'm not plotting and asking about it.

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!
