Attempting to make transparent wood
Why Hacker News recommends it
Linked as the go-to hands-on demonstration of how transparent wood is made and why scaling it to large pieces is hard.
What it is
NileRed attempts to make transparent wood, inspired by an AvE video, by removing lignin and infiltrating the wood with resin. It is a long, detailed walkthrough of the chemistry and the practical difficulties.

NileRed on youtube has a cool video detailing the steps to create transparent wood. His result isn’t quite as clear as in the article but the process seems similar. [this video]

there's a few videos from years ago attempting earlier versions of this[0]. In the end, it is very little "transparent wood" and more "plastic with wood bits in it". [0] e.g. [this video]

Process-wise I think this is an industrial version of what NileRed [0] and prior AvE [1] tried. Pretty cool, if it's truly a durable alternative. [0] [this video] [1] [LINK]

> Not sure how they "infuse" it. That sounds like driving it deeper. NileRed did a video about preparing this from a different paper: [this video] It seems that you just soak the thing in epoxy in a vacuum. The results were not great, though.

Nile Red has a video where he makes this: [this video] As you can see from the video it is basically impossible to scale this process to large pieces of wood. Discussions about replacing windows with this are pretty pointless I think.

This looks like it can be accomplished with minimal basic chemistry and a hydraulic press. I'd love to see what type of acoustic guitars could be created using this material. Super thin tops and super rigid bodies are exciting. The NileRed YouTube channel goes into the lignin removal chemistry here [this video] There's also great progress in using nanocrystalline cellulose to produce super strong composite materials. Embedding graphene or carbon nanotubes gives you super light, super tough material that is suitable for replacing aluminum and steel structures.
