GHD's Duet Blowdry Packs Power and Fantastic Styling—for a Price

GHD says the Duet Blowdry checks the surface temperature of the device 400 times per second to make sure it's maintaining the heat throughout your use—even more than the 250 times a second in GHD's similarly equipped Chronos Max hair straightener (7/10, WIRED Review). Also similar to the Chronos straightener, which has just one heat setting of 365 degrees Fahrenheit, the Blowdry only heats to a single heat level: 248 degrees Fahrenheit, which GHD says is an optimum low styling temperature. While 248 degrees is low compared to other heat tools like straighteners or curling irons, it is on the hotter end for blow-dry brushes, which often offer heat levels closer to 200 (though the highest level on some, like the Revlon, reaches up to 240 degrees).
The Duet Blowdry also promises virtually no heat damage. I think this will hugely depend on how delicate your hair is and if you're using a heat protectant as you should be, since you are using a heat tool on your hair and wet hair is especially delicate. While GHD describes this as a wet-to-dry brush, the brand says you can't really create a shape with your hair until it's 80 percent dry, but you can still use the Duet Blowdry to get your hair to that 80 percent point before using it to truly style your hair. Personally, I just wait until my hair is somewhat dry to even start using it, but you might want more drying assistance if you have longer hair. Lovely Locks

Whether or not the heat damage claims are true, the blowout itself is fantastic. I'm consistently impressed with how much volume I get without feeling like I'm in a wind tunnel, and I have fewer flyaways than I usually would. My blowout lasts longer, too, looking better than usual on day two or three thanks to the low-frizz results without losing volume or getting oily like my hair does after a serious hair-straightener sesh.
Is it worth the splurge? Personally, as someone who uses one of these devices after every hair wash day, it would be worth it for me. It's the best result I've gotten by far. While it is twice the price of a Drybar or T3 blow-dry brush, the less frizz and smoother results that last for days are something I'd splurge on for my everyday tool.
However, it is a bummer that for the price, you're only getting a single tool. It makes sense considering the design and technology packed into it that's specifically made for a blowout brush, and thus why it's such a good blowout brush, but other similarly priced options like the Shark FlexStyle (9/10, WIRED Recommends) or FlexFusion have a similar price point and come with multiple attachments. Still, my editor finds she still needs to follow up with a proper flat iron after a blowout with her FlexFusion, while I certainly don't need one after a morning with the Duet Blowdry.

Fervo Uses Oil Drilling Technology to Dig Deep for Clean Geothermal Energy

Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The U.S. oil and gas industry sparked an energy revolution a few decades ago by thinking in a different direction—literally. Horizontal drilling, combined with hydraulic fracturing, unlocked new petroleum reserves and quickly propelled the U.S. to global leadership in oil and gas. Fervo Energy, a company headquartered in oil capital Houston, is aiming for a similar revolution in geothermal energy by borrowing a page from the oil industry's playbook. "Drilling is drilling," Fervo's Vice President of Strategy Sarah Jewett told Newsweek. "That is kind of the 'aha' moment that our founders really found when they started this business." By using drilling technology advanced by the oil and gas industry, Fervo is drilling deeper, drilling sideways and drilling in new places to unlock new reserves of heat energy. A member of Fervo Energy's drilling rig crew climbs to the top of the rig in Utah. A Fervo well recently reached a depth of more than 15,000 feet, where rock is greater than 500...

More Courtesy of Fervo Energy "There's no reason why geothermal energy wells should be using older, more outdated rigs," Jewett said. Traditional geothermal energy relies on finding steam-bearing resources and drilling into them vertically to capture the steam heat. It requires not only hot rock but also enough permeability in the rock to allow water and heat to come together. That made geothermal power geographically limited to those places with just the right combination of factors. Fervo is developing an enhanced geothermal system (EGS) that creates some of those conditions by making rock permeable and injecting liquid where hot rock is available. Instead of just drilling vertical wells, the company uses horizontal drilling and hydraulic fracturing techniques to harvest naturally occurring heat. "We are just using the heat from rock under the earth rather than steam directly to create electricity," Jewett explained. The U.S. Department of Energy calls EGS "the next frontier" for renewable energy. Because the technology can tap a much wider range of geothermal resources, the DOE estimates that EGS has the potential to power more than 65 million American homes and businesses. "Really, hot rock is everywhere," Jewett said. "It's just a question of how deep that rock exists and how economic is it to actually get to [that] depth." Rock that reaches 400 to 500 degrees Fahrenheit is, generally speaking, closer to the surface in the western U.S. than in the eastern states. Fervo is focusing efforts in southwestern Utah, site of the company's Cape Station development where the company is building three power plants. Fervo Energy is building three power plants as part of its Cape Station development in southwestern Utah. The first is scheduled to come online in the summer of 2026. Fervo Energy is building three power plants as part of its Cape Station development in southwestern Utah. The first is scheduled to come online in the summer of 2026. Courtesy of Fervo Energy Jewett said Fervo's first power plant is scheduled to come online next summer with the first phase delivering 100 megawatts of clean power. An additional 400 megawatts of capacity is scheduled at the same site by 2028, and power purchasers include Shell Energy and Southern California Edison. Last week the company announced that a new round of funding for the Cape Station development had secured $206 million from investors including Breakthrough Energy Catalyst, founded by Bill Gates. In another announcement last week, Fervo shared results from one of its exploration wells that pushed the boundaries of geothermal technology. The company's deepest well yet reached more than 15,750 feet, nearly 3 miles beneath the surface. Rock temperature at that depth is greater than 500 degrees, Jewett said, and the company is testing what happens to drill bits, casings and electronics at very high heat. "One of our paths to innovation we call 'boring is beautiful,'" she said. As wells reach greater depth and higher heat, companies providing parts and services test the performance of drilling equipment under increasingly harsh conditions. "That has been a really virtuous cycle of innovation between us and our partners." In another parallel with the oil and gas industry, Fervo had the petroleum consulting company DeGolyer & MacNaughton conduct an independent energy reserve estimate for the Cape Station project. Such reserve estimates are common when oil companies develop a new resource, but the practice is new for the geothermal industry, Jewett said. DeGolyer and MacNaughton applied similar principles from oil analyses to evaluate the thermal energy potential at the site and concluded that Fervo's site could yield 5 gigawatts of power. A gigawatt is enough to power a city of 750,000 homes. With those positive developments on the technical and financial fronts, Fervo is clearly on a hot streak. But like the rest of the clean energy sector, the company is also closely watching policy developments in Washington. Tax credits from the 2022 Inflation Reduction Act were a boon for new clean energy technology developers, not only because of the size of the credits but because the 10-year lifespan of the credits provided long-term stability to attract private investors. The "one big beautiful" bill approved by the Republican-controlled House of Representatives late last month would end most of those clean energy credits and debate is underway on a Senate version. "We're fighting pretty hard to preserve tax credits because for these very early projects, it's incredibly useful to have that that support," Jewett said. Fervo's first phase of development would not be affected by the changes, she said, because construction is already underway, but future projects could become more challenging. Regardless of policy changes, however, she said she is confident that EGS power will find a market as a steady source of electricity to meet surging demand. "Geothermal energy projects are capable of providing that 'always on' power," she said. "And I think that's why it's become so attractive."

Cursed New Dating App Matches You Based on the Most Deranged Thing We Can Imagine

A newly-developed dating app matches potential lovers based on their entire internet browsing histories — and we're not quite sure how we feel about it. As Wired reports, the new service is straightforwardly-named "Browser Dating," and is the brainchild of Belgian artiste provocateur Dries Depoorter. After years creating one-off projects like "Shirt," a top that increases one euro each time it's purchased, Depoorter took a different route with his new app that invites lonely users to upload their entire internet footprint — blessedly sans "Incognito" mode — in pursuit of love. "Instead of choosing the best pictures or best things about yourself, this will show a side of you that you'd never pick," the artist says of the site, which launched earlier in June. "You're not able to choose from your search history — you have to upload all of it." If that sounds like a privacy nightmare to you, you're not alone — and although Depoorter claims Browser Dating "is not exposed to the internet," Futurism found when going through the site's application process that that might not be the case. Pretty soon into the application, Browser Dating asks users to download an extension that will give the site permission to access and export your browsing history. Though Depoorter stores user information on Firebase, Google's data storage platform used in developing AI apps, there's no reason that bad actors couldn't breach the extension itself, as we've seen as recently as February of this year. As Wired notes, the artist has previously played with the concept of privacy invasion. In 2018, for instance, he used public surveillance camera footage of people jaywalking to create art. The "surveillance artist," as the New York Times once called Depoorter, returned to his voyeurism for "The Follower," a 2022 project that used webcams in public spaces to record people as they took selfies. In both projects, it seems that Depoorter published footage of his unwitting subjects without consent — which doesn't exactly set a great precedent for his new app, though he insists it's not a gimmick. We've reached out to the artist to ask what precautions, if any, he's taken to protect against any breach of the Browser Dating extension. All told, this Futurism reporter didn't complete the site's registration once asked to download the extension. As always, it's better to be safe than sorry.
