The Download: Saudi Arabia's sci-fi megalopolis and sleeping babies' brains

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

These exclusive satellite images show the Saudi sci-fi megacity is on the right track

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 only 200 meters wide. Within its mirrored, car-free walls, residents would be transported in subways and electric air taxis.

Satellite images of the $500 billion project obtained exclusively by MIT Technology Review show that the line’s vast linear construction site is already taking shape. Visit The Line’s location on Google Maps and Google Earth, however, and you’ll see little more than bare rock and sand.

The strange gap in imagery raises questions about who can access high-resolution satellite technology. And if the largest urban construction site on the planet does not appear on Google Maps, what else do we not see? Read the full story.

Why babies sleep so much

Babies spend much more time sleeping than waking up. Scientists still don’t know exactly why, but new technologies are beginning to unravel this mystery a bit more and could help reveal what’s going on inside a newborn’s rapidly developing brain.

During the first few months, babies’ brains develop connections at a rate of about one million synapses per second. These connections are thought to play a key role in helping babies learn to make sense of the world around them, laying crucial foundations for the rest of their lives. Read the full story.

The big story

The future of urban housing lies in energy-efficient refrigerators

June 2022

The aging apartments under the New York City Housing Authority’s trusteeship don’t cry out for innovation. The largest landlord in the city, home to nearly 1 in 16 New Yorkers, NYCHA has seen its buildings literally crumble after decades of deferred maintenance and mismanagement. It would take about $40 billion or more, at least $180,000 per unit, to restore the buildings to good condition.

Despite the scale of the challenge, NYCHA hopes to address it. It launched a Clean Heat for All Challenge that 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 enormous and good for the planet.

After all, it is much more sustainable to renovate existing buildings than to tear them down and build new ones. Read the full story.
