The Download: saving Louisiana from sinking, and the promise of thermal batteries

Plus: the bitcoin halving commeth

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

How to stop a state from sinkingIn a 10-month span between 2020 and 2021, southwest Louisiana saw five climate-related disasters, including two destructive hurricanes. As if that wasn’t bad enough, more storms are coming, and many areas are not prepared.

But some government officials and state engineers are hoping there is an alternative: elevation. The $6.8 billion Southwest Coastal Louisiana Project is betting that raising residences by a few feet, coupled with extensive work to restore coastal boundary lands, will keep Louisianans in their communities.

Ultimately, it’s something of a last-ditch effort to preserve this slice of coastline, even as some locals pick up and move inland and as formal plans for managed retreat become more popular in climate-­vulnerable areas across the country and the rest of the world. Read the full story.

How thermal batteries are heating up energy storage

We need heat to make everything from steel bars to ketchup packets. Today, a whopping 20% of global energy demand goes to producing heat used in industry, and most of that heat is generated by burning fossil fuels. In an effort to clean up industry, a growing number of companies are working to supply that heat with a technology called thermal batteries.

It’s such an exciting idea that MIT Technology Review readers have officially selected thermal batteries as the reader’s choice addition to our 2024 list of 10 Breakthrough Technologies. Here’s a closer look at what all the excitement is about.

Quote of the day

“If you were wondering what they’re using to train GPT-5, well, now you know.”

—John Levine, creator of a site designed to trap web crawling bots, explains his site has received millions of pings from OpenAI bots over recent days, as they indiscriminately hoover up internet data used to train AI models, 404 Media reports.

The big story

How robotic honeybees and hives could help the species fight back

October 2022

Something was wrong, but Thomas Schmickl couldn’t put his finger on it. It was 2007, and the Austrian biologist was spending part of the year at East Tennessee State University. During his daily walks, he realized that insects seemed conspicuously absent.

Schmickl, who now leads the Artificial Life Lab at the University of Graz in Austria, wasn’t wrong. Insect populations are indeed declining or changing around the world.

Robotic bees, he believes, could help both the real thing and their surrounding nature. Read the full story.
