How chemists could give new life to old wind turbine blades

The news: Wind turbines are crucial for addressing climate change, but when they’ve reached the end of their lives, turbine blades could add up to a lot of waste. Now new research, published in Nature, could represent a first step toward building renewable-energy infrastructure that doesn’t end up in a landfill.

Why it’s a challenge: Wind turbine blades need to be tough to be useful. But as a result of their durability, they can’t currently be recycled. The new work describes a way to recover the main components of wind turbine blades, breaking down the plastic that holds them together without destroying the material’s primary building blocks. 

Why it matters: This is the first time that researchers have been able to break down a reinforced epoxy material to recover both the plastic’s building blocks and the glass fibers inside without damaging either. Read the full story.

How worried should we be about AI?

Geoffrey Hinton, the AI pioneer who just stepped down from Google so he could freely discuss his concerns about the technology, will be in conversation with Will Douglas Heaven, our senior AI editor, this afternoon at 1pm ET. It’s part of our EmTech Digital lineup, and if you haven’t already, it’s not too late to register for tickets.

The big story

The internet runs on free open-source software. Who pays to fix it?

December 2021

Volkan Yazici is a member of the Log4J project, an open-source tool used widely to record activity inside various types of software. It helps run huge swaths of the internet, including applications ranging from iCloud to Twitter, and he and his colleagues are desperately trying to deal with a massive vulnerability that has put billions of machines at risk. 

The vulnerability in Log4J is extremely easy to exploit. After sending a malicious string of characters to a vulnerable machine, hackers can execute any code they want—and years later, there’s still no clear end in sight. Read the full story.
