Inside the world’s deepest and longest subsea road tunnel

—Niall Firth

I’m currently around 1,000 feet beneath the North Sea, in a dark, dank cave. It smells weird. And I’m increasingly aware of the pressure from millions of tons of seawater just above my head.

I’m under the iconic fjords of Norway to visit what will soon become the world’s longest and deepest subsea road tunnel—an exceptional engineering feat that will carry drivers deep beneath the North Sea.

I’m here to understand how you make a 16.6-mile highway that sits 1,280 feet below the sea at its deepest point. And also—at a time when it can feel hard to get anything done—to reassure myself that ambitious engineering is still possible. That we can still make things. 

Step inside Norway’s Rogfast tunnel and see how engineers are making it happen.

Want to get a data center online quickly? Give it some flex.

The AI boom is putting unprecedented pressure on the electric grid. But rather than rushing to build new power plants, companies could find part of the solution right under our noses—or, more precisely, in the transmission lines under our feet and above our heads.

If data centers can limit the power they draw during high-demand stretches, they won’t need to wait for big infrastructure upgrades or build their own off-grid generation.

The idea of flexibility isn’t entirely foreign to grid operators. But a new generation of software could make the process faster, smarter, and more precise for the AI era.

Find out how the challenge of powering AI could lead to a smarter, more flexible grid.

How mobile money supercharged Kenya’s sports betting addictionAs the lorry he’d flagged down lurched through Kenya’s western highlands, Bill Kirwa’s Infinix smartphone dinged with a notification. The bet of 3,500 shillings he’d placed with mobile money—then worth approximately $35—had just turned into nearly $8,500.

Kirwa, now 26, put the windfall to good use, purchasing a car that enabled him to drive for Wasili, an Uber-style ride-hailing service. But he continued gambling, and over time, his losses mounted. In just a few years, he’s effectively erased his big win.  

Kirwa’s experience is hardly unique. Across Africa, the rapid spread of smartphones and mobile money has fueled an explosion in online gambling. But nowhere is the craze as acute as it is in Kenya. Find out why.
