Let's see if this is a quantitatively plausible concern. https://en.wikipedia.org/wiki/Aluminium_chloride says orl-rat LD₅₀ of AlCl₃ is 380mg/kg, which is 20.2% aluminum by weight, so that's 77mg/kg of soluble aluminum ions. If this toxicity is due to soluble aluminum ions (rather than, say, acidity), and rats and humans are about equally sensitive to aluminum toxicity, you'd need about 3.8g of aluminum to kill a 50k…

#122This made me wonder about a 3D printer alternative that builds things by folding a thin sheet of metal into arbitrary shapes instead of extruding filament.

Such as?
I have used it to repair torn foil of photographic umbrellas and softboxes, seal light leaks on a repaired darkroom enlarger head, make a reflective pattern for a photo shoot, add a temporary airtight seal on a cracked tube with just two thin layers of tape. The main issue with the foil tape I have is that it is both thin and very sticky so it can be a pickle to remove. Not really tested its conductivity yet but for…

Read this guy's ramblings and give me one cool application that he has found. Lots of "maybe it could do this!" and "it can do !"
The trick to being a good hacker is acquiring a sufficient supply of useless information, such that when that information is suddenly not useless, you have it at hand. Which is to say, it's your job to figure out what the cool applications are.

#126It's non-toxic and food safe, and yet a significant number of people on the internet still act like it's poison that will give you Alzheimer's. I wonder how many of those people touch their lips to the lid of an aluminum beverage can. Or how they might bake a lasagna at home.
cost and availability somehow has a negative correlation to how we treat something.

Hi there! Thanks for the original post, and this sentence which exists in the same liminal space as the original post. Tell me more about the matter compiler as you imagine it?
You're welcome! It's a pretty broad term, with a lot of possibilities, but generally I mean a machine which, given a design for a machine in the form of digital data, can build a working machine of that design without further human interaction. Some imperfect approximations of the idea already exist: - living things such as bacteria, humans, and plants: DNA is digital, true, but it's an unsolved problem to design the…

aluminum foil is generally not something you can recycle. Not that it can't be recyled, but the oxide to pure aluminum ratio is high and so you don't gain much since you need all the energy of refining in the first place to get back to something usable. Amazon needs stronger boxes than foil anyway. Cardboard is likely best for them.
the oxide to pure aluminum ratio is high For some definition of high? Standard foil is around 20 um thick while the oxide layer only goes about 10 nm deep.

There's no risk to leeching, there's no data proving any link at all between Aluminum and Alzheimer's. I was a huge advocate for staying away from Aluminum cooking stuff for a long time and my mother even wound up with Alzheimer's. Simply put, I was wrong, there's no link.

" EFSA (European Food Safety Authority) says acidic or salty foods can increase aluminum leaching from pans and foil into food: https://efsa.onlinelibrary.wiley.com/doi/pdf/10.2903/j.efsa....

Aluminum is generally thought to be benign by most authorities. However, it is worth noting that humans were not exposed to aluminum in the environment until relatively recently, when we started extracting it from bauxite and melting it.
Aluminum is a major component of all soils, and soluble aluminum salts have been used in medicine and dyeing since ancient Greece, probably since ancient Egypt. They have been used in food preparation for at least several centuries.
I'll readily sprinkle soluble sodium chloride salt over my food. I still very much prefer to keep both substances away from it in elemental form.
Note that I'm not claiming aluminium were dangerous, just that your argument is deeply flawed.
