The Download: training robots with gen AI, and the state of climate tech

This is today's edition ofThe Download,our weekday newsletter that provides a daily dose of what's going on in the world of technology.

AI-generated images can teach robots how to act

Generative AI models can produce images in response to prompts within seconds, and they've recently been used for everything from highlighting their own inherent bias to preserving precious memories.

Now, researchers from Stephen James's Robot Learning Lab in London are using image-generating AI models for a new purpose: creating training data for robots. They've developed a new system, called Genima, that fine-tunes the image-generating AI model Stable Diffusion to draw robots' movements, helping guide them both in simulations and in the real world.

Genima could make it easier to train different types of robots to complete tasks-machines ranging from mechanical arms to humanoid robots and driverless cars-as well as making AI web agents more useful. Read the full story.

These 15 companies are innovating in climate tech

We've just unveiled our 2024 list of 15 Climate Tech Companies to Watch. This annual project is one the climate team at MIT Technology Review pours a lot of time and thought into, and we're thrilled to finally share it with you.

Our goal is to spotlight businesses we believe could help make a dent in climate change. This year's list includes companies from a wide range of industries, headquartered on five continents. If you haven't checked it out yet, I highly recommend giving it a look. Each company has a profile in which we've outlined why it made the list, what sort of impact the business might have, and what challenges it's likely to face.

Casey Crownhart, our senior climate reporter, has dug into what these pioneering businesses reveal about the race to address climate change. Read about what she found out here.

The big story

This town's mining battle reveals the contentious path to a cleaner future

January 2024

In June last year, Talon, an exploratory mining company, submitted a proposal to Minnesota state regulators to begin digging up as much as 725,000 metric tons of raw ore per year, mainly to unlock the rich and lucrative reserves of high-grade nickel in the bedrock.

Talon is striving to distance itself from the mining industry's dirty past, portraying its plan as a clean, friendly model of modern mineral extraction. It proclaims the site will help to power a greener future for the US by producing the nickel needed to manufacture batteries for electric cars and trucks, but with low emissions and light environmental impacts.

But as the company has quickly discovered, a lot of locals aren't eager for major mining operations near their towns. Read the full story.
