Hacking the atmosphere: Geoengineering gets a reality check

Hacking the atmosphere: Geoengineering gets a reality check

Jim Franke pulls away the cover page of a presentation on the wraparound desk in his office, revealing an illustration of an odd-­looking aircraft with massive wings stretching out from a stubby fuselage. The uncrewed plane is soaring thousands of meters higher than commercial jets fly—so high you...

Entrepreneurs in Nairobi make the case for going solar

__________________________THE PLACENairobi, Kenya Most of Kenya’s power grid runs on renewables. But with 25% of communities lacking centralized electricity, the nation is looking to off-grid solar to hit its goal of delivering universal electricity access by 2030 without driving up emissions. The...

AI at MIT

AI at MIT

At MIT, AI has become so pervasive that you can almost find your way into it without meaning to. Take Sili Deng, an associate professor of mechanical engineering. Deng says she still doesn’t know whether she’d have gone all in on artificial intelligence had it not been for the covid pandemic....

Artificial scientists

Artificial scientists

AI companies frequently invoke the possibility of AI-enabled scientific discovery as a justification for their existence: If the technology eventually cures cancer and solves climate change, then all the carbon emissions and slop videos will have been well worth it.  Already, LLMs can assist...

Desalination technology, by the numbers

Desalination technology, by the numbers

When I started digging into desalination technology for a new story, I couldn’t help but obsess over the numbers. I’d known on some level that desalination—pulling salt out of seawater to produce fresh water—was an increasingly important technology, especially in water-stressed regions including...

MIT Technology Review Explains: Let our writers untangle the complex, messy world of technology to help you understand what’s coming next. You can read more from the series here. As the conflict in Iran has escalated, a crucial resource is under fire: the desalination technology that supplies water...

Are high gas prices good news for EVs? It’s complicated.

Are high gas prices good news for EVs? It’s complicated.

I live in a dense city with plentiful public transportation options and limited parking, so I don’t own a car. I’m often utterly clueless about the current price of gasoline. But as the conflict in Iran has escalated, fossil-fuel prices have been on a roller-coaster, and I’ve started paying...

How much wildfire prevention is too much?

How much wildfire prevention is too much?

The race to prevent the worst wildfires has been an increasingly high-tech one. Companies are proposing AI fire detection systems and drones that can stamp out early blazes. And now, one Canadian startup says it’s going after lightning. Lightning-sparked fires can be a big deal: The Canadian...
