This is probably the best use of Christmas trees (though it’s up for debate whether it’s a good idea to cut down spruce trees to begin with).
Side note: it was hard to find this story on a website that’s not exclusive access or enshitified. Even the company who built the turbine (#Modvion) has a tor-hostile website themselves.
According to the BBC Newsroom they use glue instead of bolts to hold it together.
Are the windblades also made of wood? That would take away one another argument from big oil used against wind turbines, and only would leave them the “but it kills birds”.
I think they said the blades were wood when I heard it on BBC.
W.r.t killing birds, I thought that was solved a long time ago just by increasing the resistance so the blades turn slowly enough to be seen. If wood blades would have to move faster, then perhaps the birds would be threatened again.
This article is claiming that the blades are still fiber glass: https://interestingengineering.com/innovation/worlds-tallest-wooden-wind-turbine
Iirc wind turbine blades are the largest user of balsa wood in the world. Of course they cover it in fiberglass and resin to make it stronger…
