Zap Energy shows off its new fusion power prototype, Century

For fusion power aficionados, hitting “breakeven” is something of a Holy Grail: the point at which a fusion reaction produces more power than was required to ignite it. Only one scientific experiment, at the National Ignition Facility, has accomplished that feat, and it took over a decade of tweaking the system to achieve the monumental result.

“The day of the NIF result was, obviously, this incredibly celebrated scientific result. They all deserve Nobel Prizes,” Benj Conway, co-founder and CEO of Zap Energy, told TechCrunch. “But you know, the day after, the question is, well, so what? What next?”

And while the NIF has managed to improve upon its first result, its device is something of a dead end. It was meant to probe the limits of physics, not sell power to the grid.

For a startup like Zap, “so what” needs to have a better answer.

Zap’s answer, so far, is a new device it calls Century, for which it recently raised a $130 million Series D. After keeping Century under wraps for several months, the startup gave TechCrunch a peek under the hood, sharing exclusive details about its operation and what it hopes to learn by using it.

Zap is taking a unique approach to fusion power known as sheared-flow-stabilized Z-pinch. Instead of using magnets or lasers to squeeze the plasma, it sends a bolt of electricity through a plasma stream. That current generates a magnetic field which compresses the plasma — the pinch — and ends up with fusion. The company had been studying the phenomenon through a series of devices at its facilities in Washington State.

But Century isn’t just another physics testbed, Conway said. 

“Our focus is not just on physics, but also on systems engineering. We’re not just a plasma physics company. We’re developing all of the key enabling technologies that we’re going to need to deliver commercial fusion. We think that doing all of this in parallel — everything all-together, all-at-once type thing — is the fastest way to actually deliver a commercial product,” he said. “Century is the incarnation of that.”

The demonstration device stands about a story and a half tall, and the liquid bismuth-lined reaction chamber inside is the size of a domestic water heater. Altogether, the key components occupy as much space as a double decker bus, and Zap thinks its commercial-scale module, which should produce 50-megawatts of electricity, will occupy a similar footprint.

To remain on track to a commercial power plant, Zap needs to hit three milestones: First, it needs to be able to generate high-voltage pulses frequently and continuously. A few weeks after it was turned on this summer, Century fired 1,080 consecutive pulses. So far, so good.

The next step is to demonstrate the technology for the Department of Energy, running the device for more than two hours by firing at ten second intervals to generate at least 1,000 plasma pulses. Ultimately, to operate as a commercial power plant, Zap’s reactor will need to spark 10 pulses per second for months on end.

After Century completes the demonstration for the Department of Energy, the team will add more liquid bismuth to the reaction chamber. The molten metal protects other parts of the device while absorbing heat that, in a commercial implementation, can be used to generate electricity. Century will be able to hold over one metric ton of the liquid metal, though for now it’s starting with 70 kg.

Lastly, the company needs to ensure that its electrodes, the parts that generate the electric pulses, can withstand the heat and particles unleashed by each fusion reaction. Those parts won’t last forever; all commercial power plants have to undergo maintenance at some point. The question is usually how frequently and for how long. Zap needs to ensure its most vulnerable parts can last long enough to make financial sense for power producers.

By next year, the company will increase the amount of electricity that’s delivered to the reaction chamber until it hits 100 kilowatts. Along the way, Conway expects the company will revamp the Century bit by bit. “Even though Century is one platform, one name, within it are multiple generations,” he said. “We iterate within the iterations.”

If Century works as planned, “my hope would be that we’re building a demo well in this decade,” Conway said. And if that goes well, commercial power plants should follow in the early 2030s.

That’s a lot of “ifs,” something Conway acknowledges. “I’m convinced that when we cut the ribbon on our first power plant and we think about the hardest problems we’ve had to solve in the last five years, my guess is plasma physics and gain is on the list. But I bet there’s a lot of other stuff on the list as well.”

That “other stuff” might be what makes or breaks commercial fusion power. 

“Fusion needs to compete with other ways of making electricity and heat. If fusion power plants cost a lot more than other ways of making electricity, there’s not going to be many of them. There may be one that we take our kids to and show on a school field trip, and that’s it,” Conway said. “The economics of these things is going to really matter.”

US v. Google antitrust trial: updates

It’s Internet Explorer day in US v. Google!

We’re a bit over an hour into Sundar Pichai’s testimony in US v. Google, and we’ve spent a surprising amount of the morning in a time machine back to 2005.

That’s when Microsoft released Internet Explorer 7 (the browser a Pichai-led team would ultimately crush by launching Google Chrome). At the time, Google’s legal chief David Drummond sent Microsoft a letter that was very mad about search defaults. Drummond wanted a choice screen, and said Google was very worried about the anticompetitive nature of Microsoft prioritizing its own search engine.

Pichai is being asked a lot of questions that amount to, “this is now the argument against you, right?” So far, he’s sparring with it pretty well.

This test could reveal whether gravity is subject to quantum weirdness


How can we test whether gravity is quantum?

Though physicists have competing ideas of what quantum gravity could be like, they have yet to definitively determine whether the gravity that we experience is quantum at all. A new proposal lays out a way to dispute or affirm this by observing whether a quantum object’s state is affected when its gravity is measured.

Physicists have repeatedly shown that tiny objects are subject to quantum effects, but for large objects whose behaviour is highly affected by gravity – with black holes being the most extreme example – the same…

I’ve spent the last 2 weeks speaking to AI – here are my 3 biggest takeaways

Published

on

A person using dictation with a smartphone.

If you’ve been following the latest AI news then you’ll know that chatbots that you can talk to using your voice are here. OpenAI was one of the first to demo the technology with its ChatGPT Advanced Voice mode (currently only free for 10 minutes a month), but Google got to market first with Gemini Live (now free to all Android users), and recently Microsoft joined in by revamping its Copilot website and app (which is free to everyone) to include voice conversations.

The ability to talk to AI using our voice, and have it talk back like a human, has been the sci-fi dream ever since Captain James T. Kirk addressed the ship’s computer in Star Trek, but it was later sci-fi creations that proved indistinguishable from human beings, like HAL 9000 and the Blade Runner replicants, that ignited our imaginations about the possibilities of an AI that could interact like a human.

Now we appear to be living in the future, because you can, right now, have a conversation with AI using the smartphone or computer you’re reading this on. But while we’ve made huge progress towards a human-like companion, there’s still a long way to go, as I discovered recently by putting the latest voice-controlled AIs – ChatGPT Advanced Voice mode, Gemini Live, and Copilot – through their paces for a couple of weeks. Here are my top three takeaways:

The BenQ X300G 4K gaming projector is $500 off for Prime
BenQ X300G 4K gaming projector Prime Big Deal Days featured
BenQ

When it comes to some of the best Prime Big Deal Days discounts, expensive gear is at the top of the list. Why? Because it’s one of the few times you can find a great price. Take, for example, BenQ’s X300G portable 4K gaming projector which is normally $1,500. That’s a hefty chunk of change, but for the event it’s $500 off, down to $1,299. That’s a fantastic discount and a great price for a capable smart projector with a lot of excellent features.

Why shop this BenQ X300G 4K gaming projector deal for Prime Big Deal Days

Let’s start with the visuals. This projector offers a stunning 4K ultra-HD resolution and works with various devices, but it has been designed for gaming. At full HD 1080P — yes a lower resolution — it offers a 4ms response time and 240Hz refresh rate. Now, that’s also while projecting up a 100-inch super large screen. Plus, you get immersive audio thanks to two built-in 8-watt speakers powered by BenQ’s CinematicSound technology. It makes it all feel like you’re in a movie theater.

The projector also acts as an all-in-one smart entertainment hub. The cast media from Android and iOS devices, via Chromecast or AirPlay, but it also has the Android TV streaming platform built-in. That allows you to stream all your favorite apps and services right away. If you plug into consoles, like a Switch, it uses one USB Type-C cable to display and charge. Moreover, it has several ports like USB, HDMI with audio return, and USB Type-C DP-enabled.

Either way, it’s a great projector to set up at home or bring to a friend’s house when you’re having an impromptu gaming session. But don’t take that to mean it’s for games only. It plays a variety of cinematic content too and would do just great as a movie theater-style projector.

Normally $1,500, this BenQ X300G 4K gaming projector is only $1,299 during Prime Big Deal Days — saving you $500.
