This geothermal startup showed its wells can be used like a giant underground battery
In late January, a geothermal power startup began conducting experiments where it pumped water deep below the desert floor of northern Nevada.
The results—which MIT Technology Review is reporting exclusively—suggest that Houston-based Fervo can create flexible geothermal power plants, capable of ramping electricity output up or down as needed.
Potentially more importantly, the system can store up energy for hours or even days and deliver it back over similar periods, effectively acting as a giant and very long-lasting battery.
There are remaining questions about how well this method will work on larger scales. But if it succeeds, it could fill a critical gap in today’s grids, making it cheaper and easier to eliminate greenhouse-gas emissions. Read the full story.

Cartier and Tiffany are getting into AR to sell luxury to Gen Z
Our senior reporter Tanya Basu recently tried on a Cartier Tank watch and a slew of Tiffany bracelets, watching the metal and diamonds shine in the dim light. It wasn’t at a store, though; she was in bed, barefoot and in sweatpants, using an AR experience on Snap that let her see how the jewelry looked on her wrist.
The Cartier and Tiffany AR campaigns are the latest in a series of collaborations Snap is making with brands to get Gen Z to invest in luxury using virtual try-on experiences. There’s evidence that, while they might not drive immediate purchases, these campaigns can change consumer attitudes and behavior. Read the full story.

Inside Alphabet X’s new effort to combat climate change with seagrass
November 2022
For years, Tidal, a project within Alphabet’s “moonshot factory” X division, has been using cameras, computer vision and machine learning to get a better understanding of life beneath the oceans, including monitoring fish off the coast of Norway.
Now, Tidal hopes its system can help preserve and restore the world’s seagrass beds, accelerating efforts to harness the oceans to suck up and store away far more carbon dioxide. Read the full story.
