A snow shoveling robot shouldn’t look human, that is the least efficient shape to remove snow. It should look more like a snow blower with a pole that can see 360 degrees to allow it to maneuver. It should have a low center of mass.

#13 That is not linoleum. It is vinyl, pvc based floorings made for wetrooms. Linoleum is natural, made of linoil, kork and wood pulp, not made for wetrooms. Linoleum is historacly used as a term for floorings, but is an actual product.

Looking at this thing, I very much wonder where its center of gravity is. Unless it weighs a LOT, and its mass is all down by those treads, it won't be able to scoop very much at a time. Better than nothing, but a wider base or a way to vary the position of its "torso" would help.

5 days ago | Likes 1 Dislikes 0

I bet a large portion of the weight is down at the base. That looks to be where the batteries are stored - although who knows how much all the other components weigh.

#1 ok i admit it, i officiallly hate the ai age now. I don't know whether to hate on whoever made/cut the video or on the program he used to generate it because I can't tell. Other than the language/phrasing is weird.
But it neglects to tell us how the interesting 'cake' shape forms when he gathers the iron. And more importantly doesn't specifically mention the crucial step of introducing enough carbon into the mix, so that iron becomes steel.

6 days ago | Likes 32 Dislikes 1

All you questions where answered in the original video someone ripped off and put their own AI dub on. They are using a ring shaped magnet. Likely from an old speaker. Carbon is introduced with the charcoal, which is almost pure iron. The reason I hate AI bullshit videos like this is 99/100 times the original was better. Someone just didn't want their voice attached to plagiarism.

There should also be a tempering step after the quench, otherwise that blade will be glass-brittle. The cake is iron filings stuck to a ring shaped magnet.

They're using a perfectly ring shaped magnet, just like in Ancient China. Such an idyllic return to a simpler time!

And they mig welded the "sand" into a steel box to pattern weld in the forge, just like the ancients did.

The narrative description of creating steel from black sand is accurate to the actual historical method. The video is a lie. Black sand is not the same as magnetic iron filings which is what is shown in the video

5 days ago | Likes 11 Dislikes 1

The video isn’t too inaccurate… I’ve done a very similar (smaller) process.

Not all black sand is iron, but what sticks to a magnet is. What’s missing is that that fuzzy ring took probably a good hour or two of sifting through (and washing away) silt, and you constantly have to keep finding new iron-rich areas.

Using natural lodestone magnets takes longer, and doing it without a magnet is possible, but even worse: https://youtu.be/DyGLE0usN_I

The 'cake' shape really, really acts like he's got a giant ring magnet.

The cake shape forms around a magnet that attracts particles of iron ore from the river silt.

#2 The boiling at the end kills the larva, if they don't they'll chew up the long strands. That's why wild silk has shorter fibers, they don't kill them prematurely but only harvest the leftovers.

If the content firms behind it are state funded with the intent to shift the public's perception of China, how is it not propaganda? It might be true method, but they were practiced other places as well, so really the intent behind it makes it propaganda.

Considering what happens to a butterfly's body when in a pupal stage makes me wonder if they're even conscious when they're being boiled like that. It's still absolutely brutal though.

5 days ago | Likes 2 Dislikes 0

It’s a comforting thought, but untrue. When they pupate, they dissolve their nervous system, so they aren’t aware of what’s happening.
When they are boiled alive, every last pain receptor they have is dialed up to 11 before their flesh gives way enough to release them unto oblivion. It is a torment unimaginable to us.

#13 I much prefer to pop the toilet off first. For the cost of a new wax seal you cut the time in half and the finish is going to be far more accurate.

And when the toilet gets replaced before the floor, it just needs cleaning, not patchwork.

Good point

6 days ago | Likes 11 Dislikes 0

Please explain. Why would one require patching and not the other?

5 days ago | Likes 4 Dislikes 0

@pullingsixty is right. Almost every toilet fits a ~5” ring around the sewer pipe, but the rest of the shape can change.

If you put a toilet on top of the flooring, the flooring will be there when the toilet is removed, so you just have to clean any crud (caulk, stains, etc.) off the flooring, and a new toilet will look decent.

If you cut flooring as shown, removing the toilet leaves an old-toilet-shaped hole, which will look awkward around the new toilet shape, unless you patch it carefully.

Toilet styles change, the base that it sits on isn't the same as your flooring cutout around your old toilet, or more likely you changed brands and it has a different style.

Linoleum is extremely durable, sustainable, recyclable, biodegradable because the ingredients are things like linseed (flax) oil, pine resin, jute, finely milled wood or cork. It’s a shame it fell out of fashion. Oh yeah, and it has natural antibacterial properties.

What type of flooring do you recommend for bathrooms? I prefer both linoleum and it's slightly more modern counterpart of sheet vinyl. Both are at least half the price per square foot than luxury vinyl plank/tile and 100% waterproof vs just water resistant. Tile is also just resistant but extremely expensive. Linoleum and Vinyl sheet flooring comes in 12' wide rolls that you have the store cut to length when you buy it. So the floor is one piece and waterproof.

In the UK its called cushion floor. It's vinyl with a foam back warmer and softer than lino or tiles, and slip-resistant. It's better all around for colder climates.

If it's the same thing, it's called luxury vinyl in Canada, a big step up from linoleum.

5 days ago | Likes 3 Dislikes 0

It's called LVP or LVT for luxury vinyl panels or sheets. Those are just terms for laminate style click together flooring that isn't actually waterproof at the seams. If they have foam under them it's because that what style of underlayment the installer choose since they don't come with foam backing. They are a step down in the waterproofing department they just look fancier but offer less protection.

That's interesting you say that, I put down click vinyl in my bathroom and a couple of years in its cracking in the center of tiles. I've put down two LVP floors in the last five years and both are still going strong.
