Termite-proof?

The secret is in the reach-around.

This is a cool idea. How does it stand up to water and wear? Is it biodegradable? If it's as durable as they claim, we might have a contender for replacing a lot of plastic.

It should be all those things.
I'm not sure if this is one of those "duh, why didn't we think of this sooner " things or if there is some serious science going on. Basic wood glue works on the lignin, so that's been known for a long time.
It's cool as hell no matter what.

Nope. The termites will evolve and use tiny saws.

Could it potentially be used to replace larger building materials like rebar for example?

Brie Larson isn't all that hideous. I mean sure she's probably about a 4 but after a few drinks she'll do at closing time for a roll in the hay.

Be interesting to combine this with some crazy joinery.

It's also especially exciting if it can be made from bamboo.

Right, like has that researcher ever used a hammer and nail before?

I know, right? Maybe he was scared the nail might shatter if struck with a greater force. But generally, a capable tradesman can sink that nail in to the head with three whacks.

When I was a kid in the late sixties we had a big red oak in the yard get struck by lightening. Ruined three chain saw chains getting it cut down, snaked it into an old garden spot with a tractor. Piled up about twenty tires under and over the log to try to burn it, just scorched it. The last time I was on the property about 3 years ago most of the log was still there, with very little rotting, despite laying in contact with the ground for 50 years.

I'd be more impressed if they didn't have to tippy tap it all the way down - that alone would slow down construction by leaps and heaps.  Serious business construction nailing consists of tap BAM done or a nailgun - and if it needs to be babied like that it's not gonna go so well with either method

/still cool but that part makes me question their usefulness as nails/etc.

Bamboo has been used for concrete reinforcement for a little while now. But other inexpensive alternatives that don't require such long pieces are becoming a lot more popular. If you're interested, you should look up GFRC and other new alternatives like Lafarge's stainless steel spirals (forget the name, they're about an inch long and eliminate the need for rebar in most installations)

I'm used to wood as hard as steel. Not to brag, but at my age...

What?

Oh... you were talking about wood hard enough to nail...

What?

Don't say it like that? I thought this was about something hard enough to penetrate...

What?

HR? Again? Why?
Why is everyone rolling their eyes?

And by "new" Subby means "a couple years old and already in commercial development".
 
2021-10-24 10:06:35 PM  
I'm just curious about the total lifecycle costs- at a guess, this sounds actually way more energy intensive than plastics. It might have room to optimize, but the big reason plastics are so popular is that they're extremely easy to form and require basically nothing in terms of energy or raw materials.

Laminated beams are a thing, but hell yeah this could make them stronger.

The whole building would creak when it flexes.

I just imagine what the wood is saying to the wooden nail.  "Daddy?  Is that you?  What have they done to y---NO!!!  Don't do it!!  DAD!  Whatever they did, you can fight it!  You're wood!  Deep down you still remember, right?  Right?  Nooo-AAAAAAAAAAH WHY WHY WHY????"

If it's as hard as steel then it could be used to make firearms.

"Look out! He's got wood!"

The wood shouldn't stay that hard for longer than a few hours.

Or you could use a steel nail and not have to hit it 200 times.

I had a house with engineered bamboo floor boards, that stuff is damned hard, one large lounge load killes a drop saw blade and numerous jig saw blades.  Almost impossible to dent or scratch too.

The Japanese had a method for hardening wooden weapons to iron like strength using heat. I am betting other cultures did  as well. This is pretty cool, but very elaborate.

I hope they can make a wooden cross so I can use their wood nails to affix them to it.
