I also agree that rot is part of the normal process but HOW is this contended with?

Maybe I’m just dense, but if a part of a mammal started to necrose while still attached to the organism, there would most likely immediately be an infection present and they would probably go septic.

Nature leaves no opportunity wasted, I think it’s safe to assume that there must have been some bacteria or something like that on the flesh.

Maybe my main lack of understanding is that I am stuck thinking about how my circulatory system works, as another commenter suggested.

I happened to run into one of them a couple years back, and also happened to have a thermal camera on me at the time, and thought it was neat.

Temperature across a heat-powered fan on a wood stove. Note the nearly constant bottom section temperature, and a sharp 40F delta-T in the center where the thermoelectric pad is.

E: Sorry for the potato quality, but we're talking minimum budget FLIR Lepton here. And my MSX alignment is a bit off.

TL/DR: They don't reject electricity or any other technology outright. They pick and choose the technology that will benefit them, and reject anything they feel is detrimental.

Long version: There's many flavors of Amish, and all follow different rules. Technology is allowed or forbidden depending on its impact on the community. Telephones? Some communities love them, it brings distant neighbors together. Cellphones? Yes, for the same reason. A smartphone that lets you spend all day scrolling Reddit, that's probably not going to fly because it'll separate you from your community rather than bringing you closer.

And there's also rules for what's allowed at work. A friend of mine bought a trailer from a PA company, and she was surprised to see Amish people driving forklifts, running power tools, arc welding, etc, as part of the manufacturing process. The Amish aren't held to the same standards when on the job, because doing so would make them unemployable.

So yeah, it's not as simple as it seems, and every community is a little different.

The few Mennonites I've known have all had phones, electric lights, fridges, stoves, etc. The basic, functional stuff. One guy even kept an old laptop for doing his books.

The way it was explained to me is that modern stuff that's used to a 'good' purpose like phones for urgent communication and business, or electric refrigeration to keep food from spoiling are okay; but things meant to entertain or replace "the work of human hands" is not.

We don't build wooden ships anymore. There are no size limits for steel, and eventually the ship gets so big that weather just won't affect it much.

The Seawise Giant was 2.5x bigger than an American supercarrier. If there were a shipyard big enough to do it, there is nothing stopping us from building a ship 10x bigger, or even 100x bigger except the price tag and the lack of logical reasons to ever build such a ship due to how impractical it is

> Mennonites

There are at least a few Mennonites attending the veterinary school where I work. Women, otherwise honestly I might not have recognized them as such. They show up wearing their home sewn dresses and bonnets, and go to classes in a teaching hospital where they learn about every high-tech treatment that veterinarians now have access to.

I designed lab equipments with precision pistons made of graphite in glass tubes. It’s really good but it is expensive, especially in low quantities, something like >40$ for 1/2” diameter piston, a few inches long. There was no other way to get low friction. I imagine that other constraints gets involved when you want to get any useful energy from it, at large scale.

Unfortunately, the heat rising off the stove produces way more vertical force than these produce horizontal force.

It's better than nothing if you got one for free, but a simple box fan can move wood stove air at a much lower cost effective price.

Looks like r/woodstoving is leaking. We get questions about these things weekly.

Merely a neat looking gimmick
