I can’t believe that I’m going to be the first to say this but…
My wood is already ten times stronger than steel!
I’ll see myself out.
A US company has engineered a new type of wood that it says has up to 10 times the strength-to-weight ratio of steel
neat!
while also being up to six times lighter.
But… but that’s… that’s part of the thing. That you just said improved. The ‘weight’ part in ‘strength-to-weight’.
The company’s own website lists “weight” as a separate row item in their performance comparison chart

I think it means 10 times strength-to-weight, and 6 times strength-to-volume size
Yes, but they are different values.
Keeping strength constant, a superwood beam would weigh 10 times less (with some reduction in volume).
Keeping volume constant, a superwood beam would weigh 6 times less (with some improvement in strength)
If i had to guess then I’d guess they mean lighter by volume. Like if an i-beam made of steel weighs 6 tons, then the same size i-beam made using superwood would weigh 1 ton.
I.e. it’s 10 times better in strength-to-weight, and it’s 6 times better in strength-to-volume.
This is just my guess at interpreting what they tried to say
Um… what exactly is this picture of a weight sitting on the ground under a bent piece of wood supposed to show us?
This picture was supposed to be embedded. Not sure what I did wrong.

This would be a dream if they can produce this with renewable energy and sequester a bunch of the carbon we’ve emitted. 90% smaller carbon footprint is already really great news
Maybe it shows how much the wood bent compared to the other sample?
Yeah, but the weights are not suspended above the ground. They’re sitting on the ground. Why should I believe it won’t bend more or even break?
