This startup wants to use beams of energy to drill geothermal wells
Geothermal startup Quaise certainly has an unconventional approach when it comes to destroying rocks: it uses a new form of drilling technology to melt holes through them. The company hopes it’s the key to unlocking geothermal energy and making it feasible anywhere.
Quaise’s technology could theoretically be used to tap into the Earth’s heat from anywhere on the globe. But some experts caution that reinventing drilling won’t be as simple, or as fast, as Quaise’s leadership hopes. Read the full story.

Five things you need to know about AI right now
—Will Douglas Heaven, senior editor for AI
Last month I gave a talk at SXSW London called “Five things you need to know about AI”—my personal picks for the five most important ideas in AI right now.
I aimed the talk at a general audience, and it serves as a quick tour of how I’m thinking about AI in 2025. There’s some fun stuff in there. I even make jokes!
You can now watch the video of my talk, but if you want to see the five I chose right now, here is a quick look at them.

Why it’s so hard to make welfare AI fair
There are plenty of stories about AI that’s caused harm when deployed in sensitive situations, and in many of those cases, the systems were developed without much concern to what it meant to be fair or how to implement fairness.
But the city of Amsterdam spent a lot of time and money to try to create ethical AI—in fact, it followed every recommendation in the responsible AI playbook. But when it deployed it in the real world, it still couldn’t remove biases. So why did Amsterdam fail? And more importantly: Can this ever be done right?
Join our editor Amanda Silverman, investigative reporter Eileen Guo and Gabriel Geiger, an investigative reporter from Lighthouse Reports, for a subscriber-only Roundtables conversation at 1pm ET on Wednesday July 30 to explore if algorithms can ever be fair. Register here!

One more thing
The world’s first industrial-scale plant for green steel promises a cleaner future
As of 2023, nearly 2 billion metric tons of steel were being produced annually, enough to cover Manhattan in a layer more than 13 feet thick.
Making this metal produces a huge amount of carbon dioxide. Overall, steelmaking accounts for around 8% of the world’s carbon emissions—one of the largest industrial emitters and far more than such sources as aviation.
A handful of groups and companies are now making serious progress toward low- or zero-emission steel. Among them, the Swedish company Stegra stands out. The startup is currently building the first industrial-scale plant in the world to make green steel. But can it deliver on its promises? Read the full story.
