Wind turbine blades are incredible pieces of engineering, undergoing physical stresses that are hard to comprehend. They do eventually wear out for their main purpose, though, so what do you do with all these big blades that are still very strong, but no longer quite strong enough to spin at speed?
Well, it turns out that one of the things you can do with them is build bridges. Rather than sitting in a landfill, where they really don't break down at all, a new venture is using them to build pedestrian bridges - with the second one ever just being installed.
I think this would be a great use of the blades if it works out - maybe try them in some small buildings, too. Reuse is always better than pure recycling, after all.
Talking of wind turbines, you would think that if there is any weather condition they might be expected to survive, it would be high winds.
Well, the UK has been faced with one of the windiest weeks in decades with the arrival of Storm Eunice, and as well as the roof of the iconic Dome being shredded, it seems a wind turbine, uh, couldn't deal with the wind.
Now, wind turbines aren't expected to just spin faster and faster as the wind gets stronger - at some point, they have a braking system that stops them from overspeeding - but it seems that this turbine in Wales had some further structural defect and decided to give up the ghost. Thankfully, like pretty much all turbines, it was in a remote area and didn't damage anything.
When you build a dam to create a reservoir, there's often a high ecological cost to the land that gets submerged, and sometimes a human cost too, as previously riverside villages are forced underwater.
It seems, though, that with increasing drought levels in Spain, one of those villages is having the last laugh as it emerges once again from the shrinking reservoir, somewhat of a time capsule of when it was flooded and claimed by the rising waters back in 1992.
I'm sure this is not the last of these we'll see re-emerge - reservoirs all around the world are at record lows, with the USA's iconic Hoover Dam and Lake Mead at their lowest levels since the 1930s, for example.
