Intriguing, but I find this somewhat hard to believe.
Glu-lam isn’t new technology.
If you could achieve comparable strength: weight from timber as aluminium, GFRP, or CFRP, we’d see a high timber content in aircraft, instead of near zero.
If they’re making the blades heavier to compensate, you get all kinds of runaway knock on effects. Blades are heavier, so need to be stronger, so need to be heavier… tower, bearings, foundations, mountings etc all need to be stronger.
Sort of an xkcd 808 argument.
Mass is not a major issue for towers, but it’s a big problem for rotating parts.
