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.

What’s the concern with cutting down spruce trees?

What’s the concern with cutting down spruce trees?

Some people believe trees absorb CO₂ from the atmosphere. There’s an uncited claim of 22kg/year/tree on avg for mature trees (according to the European Environment Agency). Others are claiming ½ that amount. But some people say trees are carbon neutral, and thus have no decarbonization effect. I’m not sure what to believe at this point but the benefit of living trees is clearly disputed.

One thing I’m confident about is that trees have a cooling effect by way of evaporative cooling and simply by giving shade. They also have a symbiotic relationship with boletes (mushrooms).

The trees are absorbing carbon and turn it into wood.

I'm not 100% sure but I think the best way to absorb carbon using trees is to let the trees grow and then use them in construction or furniture.

Burning them or letting them decompose.naturally will release the carbon they absorbed.
