The Download: the Saudi sci-fi megacity, and sleeping babies’ brains
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.
These exclusive satellite images show Saudi Arabia’s sci-fi megacity is well underway
In early 2021, Crown Prince Mohammed bin Salman of Saudi Arabia announced The Line: a “civilizational revolution” that would house up to 9 million people in a zero-carbon megacity, 170 kilometers long and half a kilometer high but just 200 meters wide. Within its mirrored, car-free walls, residents would be whisked around in underground trains and electric air taxis.
Satellite images of the $500 billion project obtained exclusively by MIT Technology Review show that the Line’s vast linear building site is already taking shape. Visit The Line’s location on Google Maps and Google Earth, however, and you will see little more than bare rock and sand.
The strange gap in imagery raises questions about who gets to access high-res satellite technology. And if the largest urban construction site on the planet doesn’t appear on Google Maps, what else can’t we see? Read the full story.
Why babies sleep so much
Babies spend much more time asleep than they do awake. Scientists still aren’t exactly sure why, but new technologies are starting to shed a bit more light on this mystery—and could help reveal what is going on inside the rapidly developing brain of a newborn.
During the first few months, babies’ brains are developing connections at a rate of roughly a million synapses a second. These connections are thought to play a key role in helping babies learn to make sense of the world around them, setting crucial foundations for the rest of their life. Read the full story.

The big story
The future of urban housing is energy-efficient refrigerators
The aging apartments under the purview of the New York City Housing Authority don’t scream innovation. The largest landlord in the city, housing nearly 1 in 16 New Yorkers, NYCHA has seen its buildings literally crumble after decades of deferred maintenance and poor stewardship. It would require an estimated $40 billion or more, at least $180,000 per unit, to return the buildings to a state of good repair.
Despite the scale of the challenge, NYCHA is hoping to fix them. It has launched a Clean Heat for All Challenge which asks manufacturers to develop low-cost, easy-to-install heat-pump technologies for building retrofits. The stakes for the agency, the winning company, and for society itself could be huge—and good for the planet.
After all, it’s far more sustainable to retrofit existing buildings than to tear them down and build new ones. Read the full story.
