Super interesting piece and as somebody who is interested in many things I appreciate such articles. But seeing this on #1 feels a bit off on HN. Is there a slight possibility that the feed is sometimes curated (eg through different voting powers)?

Or there is simply quite a few people like you who find this interesting, as the YC posting guidelines put it:

"If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity."

The most expensive wooden floors have the end grain exposed facing upwards and this is then compressed down, much like the top of a good quality butchers block. Those floors are just about indestructible. The heavier such floors are used the stronger they get! The wood in the article is compressed crosswise to the grain (so they get thinner rather than shorter), using the original planks as the raw organic material t…

Do you mind sharing a picture of this done right? The end grain wood floor pics I found on Google look mostly hideous to me.

Not OP, but I found some interesting information here.

Looks like it's good for outside flooring. Actually doesn't look that bad when used for that either, kind of like bricks.

It also was a traditional flooring for workshops, because it tolerated heavy abuse.

They’re both made of carbon. Parent was being cheeky.

Indeed cheeky since wood is not pure carbon, as opposed to diamonds ...

Well if you really want to split hairs, diamonds can have impurities that can cause different colors (like the blue Hope Diamond)

Interesting, but what about biodegradability? Will it not be eroded by microorganisms in the outdoors over time? It is still wood, after all.

It's still wood, and wood is only barely biodegradable. If you take decent care of it it'll last for centuries.

A fallen tree in damp conditions rots down in a year or so. Seems pretty biodegradable.

Your second sentence I have no problem with.

Engineered wood has been a thing for over 100 years. Wood has a lot of desirable properties that make it a good construction material (fire resistance for instance is much better than steel). This article is definitely missing the wood for the trees to some extent, but it is an interesting development and even if the gain isn't going to be quite as large as indicated and there are some serious questions about whether…

How is wood more fire resistant than steel? What are the metrics used for this?

Jet fuel doesn't melt wood beams.
