The Download: a bold fusion claim, and a new augmented reality game

Plus: a new way to smell things in virtual reality.

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.

This startup says its first fusion plant is five years away. Experts doubt it.

The news: A startup called Helion, backed by Sam Altman, claims it’s on track to flip on the world’s first fusion power plant in five years. That’s a dramatically short timeline for a carbon-free energy source that’s eluded scientists for three-quarters of a century.

The details: Helion has signed a deal with Microsoft for it to buy power generated by its Washington-based plant once it goes online in 2028. If it pulls it off, it’d be a huge deal. Fusion plants could deliver a steady stream of clean electricity to help meet soaring electricity demand as the world races to cut pollution from transportation, homes, office buildings, and industry.

But, but… It’s an astounding claim, and a questionable one, according to several nuclear experts. That’s because the company hasn’t said, and won’t comment, on whether it’s passed the first big test for fusion: getting more energy out of the process than it takes to drive it. Read the full story.

A first look at Peridot, the new AR game from the creators of Pokémon Go

A new mobile augmented reality game called Peridot launched this week from Niantic, the company behind Pokémon Go. It’s heavily inspired by Tamagotchi, the virtual-pet phenomenon of the ’90s. It places the player in the role of caregiver to a cadre of cartoonish pet characters superimposed into the real world via your smartphone’s camera.

The big question is whether Niantic can re-create the success of its blockbuster game Pokémon Go, which became a cultural phenomenon in 2016. Our senior reporter Tanya Basu tried it out and found that, although it did give her the same fuzzy feelings you get from pets, it became a little repetitive after a while, and drained her phone’s battery unbelievably quickly.

Smellyvision! A face mask that lets you smell things in virtual reality

The news: One of the barriers that stops virtual reality from being a fully immersive experience is that it doesn’t require you to use all your senses. A team of researchers from the University of Beijing have come up with a new way to try to address that: small, wireless wearable interfaces that let you smell odors in VR, like rosemary, pancake, and mojito.

How they did it: They developed two wearable interfaces. They both attach to the face and use miniaturized odor generators, a grid of tiny containers filled with perfumed paraffin wax. When a heat source beneath the wax is activated, the wax heats up, essentially becoming a scented candle capable of reproducing multiple odors. Read the full story.

The big story

The hunt for hidden signs of consciousness in unreachable patients

August 2021

At first glance, there’s nothing remarkable about the low-rise hospital in Milan. But two floors up, on an isolated wing, an uncommunicative man with a severe brain injury is hooked up to technology that researchers here believe can tell them if he’s conscious.

A neuroscientist and the patient’s neurologist watch on a laptop as complicated blue squiggles representing brain waves fill the screen in close to real time. What the scientists see in them is the faintest sign of a liminal, maybe dreamlike, consciousness.

Such a breakthrough represents the most accurate consciousness meter ever seen in medicine (even if it is still crude, rudimentary, and unrefined)—with wide reaching medical implications. Read the full story.
