Fervo Energy says it has achieved a breakthrough in geothermal technology. It carried out a 30-day well test at its site in northern Nevada and says it was able to achieve a “flowrate of 63 liters per second at high temperature that enables 3.5 megawatts of electric production.” The company says the test resulted in flow and power output records for an enhanced geothermal system (EGS) and that it was completed without incident.

A megawatt can power around 750 homes at once. Fervo is expected to connect its Project Red site to the grid this year. It will be used to power Google data centers and some of the company’s other Nevada infrastructure. Google and Fervo signed an agreement in 2021 to develop a “next-generation geothermal power project.”

This is the first time an energy company has shown that an EGS can work on a commercial scale, according to Bloomberg. It’s been a long road to reach this point, as scientists have been trying to make EGS a reality since the 1970s.

For a natural geothermal system to produce electricity, it needs a combination of heat, fluid and rock permeability, as Bloomberg notes. In many areas, the rock has the required levels of heat, but not enough permeability for fluid to flow through it.

An EGS creates this permeability artificially by drilling deep underground and injecting fluid to create fractures in the rock. That approach can vastly increase the number of potential sites for a geothermal power plant.

Fervo says it’s the first company to “successfully drill a horizontal well pair for commercial geothermal production, achieving lateral lengths of 3,250 feet, reaching a temperature of 191°C, and proving controlled flow through rigorous tracer testing.”

One of the major advantages of geothermal power plants is that they’re entirely carbon free — Google aims to run all of its offices and data centers on carbon-free energy by 2030. These plants can also operate at any time (unlike solar and wind), making geothermal energy a compelling source of renewable power. However, cost reductions and regulatory red tape are barriers to making EGS more broadly available, according to Fervo CEO Tim Latimer.

The company is hoping to replicate its success at a site in Utah. If Fervo sees similar results there and it successfully implements design upgrades to maximize output, the site is expected to generate enough electricity to power 300,000 homes simultaneously, Latimer said. That’s around a quarter of all homes in Utah.

“Achieving our goal of operating on 24/7 carbon-free energy will require new sources of firm, clean power to complement variable renewables like wind and solar,” Michael Terrell, Google’s senior director for energy and climate, said in a statement. “We partnered with Fervo in 2021 because we see significant potential for their geothermal technology to unlock a critical source of 24/7 carbon-free energy at scale, and we are thrilled to see Fervo reach this important technical milestone.”

Meta has delivered the first significant update to Threads since the social network launched earlier this month, and you might appreciate it if you’re still building your contact list. The company’s Cameron Roth has detailed an upgrade to the iOS app that adds a Follows tab to the activity feed, making it easier to see who just followed you. You’ll have an easier time following people back. Accordingly, you can open your Instagram follower list to see if you’re missing anyone.

The update also adds translations for post text, so you’ll have more incentive to follow people who speak unfamiliar languages. You can subscribe to unfollowed users to get notifications without crowding your timeline. There are a few basic interface tweaks as well, such as reposter labels you can tap. The app should be leaner and smoother, particularly when loading or scrolling through your activity feed.

Some of the features are enabled server-side, so don’t be surprised if they’re not all available immediately. Roth says they should be available by the end of today (July 18th). There’s no mention of when Android will get an equivalent update, but we’ve asked Meta for comment and will let you know if we hear back. The Android beta program offers features before they reach the publicly available app, however.

There are still numerous missing features, and the Threads team is aware of it. You can’t yet use a chronological feed, direct messages or hashtags. You can’t completely remove yourself from Threads without also deleting your Instagram account. And without a full web version, it’s not usually practical to use Threads on a computer. This first update shows that Meta is acting on at least some promises, even if it may take a while to address every issue.

Meta has motivation to act quickly. Threads use is declining after the initial spike, and the absence of some features (such as hashtags and a web app) may keep new users away. Greater parity could help sustain interest while Meta considers a European Union rollout and otherwise prepares for a significant expansion.

Cricut, a company that makes popular cutting machines for crafting projects, announced a new model today. Although its devices are relatively affordable, the new Cricut Venture is a higher-end $1,000 machine aimed at “incredibly enthusiastic makers and those who sell their crafts.” In other words, this variant is less for occasional hobbyists and more for hardcore makers or small businesses selling their creations somewhere like Etsy.

Cricut Venture is a “large-format” cutting machine that can handle bigger projects — whether physical size or higher volume. The device, the company’s biggest yet, can cut up to 75 feet of repeated images and 12 ft of single images. Cricut says it’s also its fastest machine, cutting up to 25 inches per second. “Cricut Venture is optimized for size and speed,” said Michelle Fishberg, Cricut’s VP of Global Product Management. “You will find the beautiful design and quality Cricut is known for, with increased precision and attention to detail, all of which make cutting on this large-format machine an easy and productive experience.”

Like the company’s other models, the Cricut Venture can handle materials like vinyl, iron-on, cardstock, bonded fabric, leather and poster boards. Engadget’s Terrence O’Brien reviewed the printer-sized Explore 3 in 2021 and found it worked well for projects like vinyl decals and cardstock animals (that he may or may not have ever fully assembled). However, these machines are more limited by the user’s experience with crafts than technology: The company lists banners, engraved metal, debased leather, custom cards, t-shirts and color stickers among the various tasks it can handle.

The Cricut Venture will be available from the company website and retail partners starting on July 25th. Its $1,000 sticker price is for the machine only; Cricut also offers bundles with a stand or materials to help you get started.
