The Download: fusion power’s future, and robotic running – MIT Technology Review

Plus: Meta is unleashing celebrity-inspired chatbots
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.
Why the dream of fusion power isn’t going away
There’s a joke about fusion power that always comes up when people start talking about the technology. It goes like this: Fusion is the energy of the future … and it always will be.
Fusion reactors could someday deliver cheap, abundant power with no carbon emissions. But the promise of “someday” has been around for a long time without payoff. Fusion has generated so much excitement but also so much skepticism. It’s the ultimate long shot in energy technology. 
But despite the massive technical challenges, the promise of fusion’s round-the-clock power with no carbon emissions means that experts say we mustn’t give up on it. Read the full story.
Psst: our climate reporter Casey Crownhart will be discussing the future of long-shot climate technologies like fusion during our second annual ClimateTech conference, taking place at MIT on October 4 and 5. Nab your ticket now!

This robotic exoskeleton can help runners sprint faster
What’s happened: A wearable exoskeleton can help runners increase their speed by encouraging them to take more steps, allowing them to cover short distances more quickly, a new study has found.
How it works: The researchers built a lightweight exosuit with steel cables powered by electrical motors attached to the runner’s thighs. The motors pull the cables, mimicking the contraction of muscles. The exosuit helps people run faster by assisting their hip extension—the powerful motion that propels a runner forward.
Big ambitions: Buoyed by their findings, the researchers want to see if their exosuit can help a runner to beat the men’s world record for running 100 meters. They’re working on a customized exosuit for Kyung-soo Oh, a former national elite runner in South Korea who had retired, in a bid to break Usain Bolt’s record of 9.58 seconds. Read the full story.

The big story
Uber’s facial recognition is locking Indian drivers out of their accounts
December 2022
One evening in February 2021, Uber driver Niradi Srikanth was getting ready to start his shift ferrying passengers around the Indian city of Hyderabad. He pointed the phone at his face to take a selfie to verify his identity. The process usually worked seamlessly. But this time he was unable to log in.
Srikanth suspected it was because he had recently shaved his head. After further attempts to log in were rejected, Uber informed him that his account had been blocked. He is not alone. 
In a survey conducted by MIT Technology Review of 150 Uber drivers in the country, almost half had been either temporarily or permanently locked out of their accounts because of problems with their selfie. It’s a glitch that can have devastating consequences for affected workers. Read the full story.
