This Portable Carafe Heats Your Water to Exactly the Temperature You Want—While You Pour

One day soon, you may not need to stand around trying to watch water boil—it will boil instantaneously as you’re pouring it into your cup. The Duo Smart Untethered Carafe, a portable smart carafe that just debuted at the consumer tech trade show CES, is designed to heat filtered water as it comes out of the spout.

Created by Heatworks, the carafe works by utilizing Ohmic Array Technology, a patented system the company developed that harnesses water’s natural conductivity to generate heat. Rather than using heating elements that then warm up the water (which lends itself to lag time), the carafe passes electrical currents through the water to increase the energy state of the water molecules. The result, Heatworks says, is instant hot water.

Because of this rapid heating ability, the Duo is able to heat water as it pours out of the carafe’s spout, rather than heating up the full tank of water, as a conventional kettle—either electric or stovetop—does. The temperature of the water can be controlled within 1°F by changing how quickly the water passes through the spout, making it the ideal product if you want to make perfect pour-over coffee. (Too lazy for pour-overs? We highly recommend Ninja's Hot & Cold Brewed System.)

The carafe features an elegant product design by frog, a global design agency that has previously worked on projects like Honeywell’s Lyric smart thermostat system. While most (though not all) electric kettles are industrial-looking and utilitarian, the Duo can blend seamlessly into your minimalist kitchen vibe. It’s battery operated, so you can store it anywhere, but you’ll definitely want to leave it out on your counter so that it's in full view of all your guests.

The only problem? You can’t buy it yet, and The Verge notes that the company doesn’t have a working prototype at CES. When it will actually hit the market is hard to say: Heatworks founder/CEO Jerry Callahan told The Verge that the hope is to ship it as soon as this summer, but there is no public target date yet. When it does come out, it will likely cost somewhere below $200.

There’s good reason to believe that Heatworks will make good on its promise. The company already sells its Ohmic Array Technology in the form of its Wi-Fi-enabled Model 3 tankless home water heater. And it just announced that its frog-designed Tetra Countertop Dishwasher, which debuted at CES last year and uses the same technology, will soon be available for pre-order, with prices starting at $299.

Netflix Viewers Are Petitioning the Streaming Giant to Stop Cutting Off the End Credits

To help us decide what to watch next as easily as possible, Netflix always serves up a few suggestions immediately after we’ve finished a program. For many viewers, it’s a little too immediate: The credits shrink to a small window, and Netflix’s recommendations take center stage.

Composer Daniel Pemberton, whose most recent scores include Netflix original films Enola Holmes (2020) and The Trial of the Chicago 7 (2020), likened it to a rushed meal at a restaurant. “The second that final spoonful goes in your mouth the waiter runs over, noisily clears the plates away and shoves a new menu under your nose, while insisting that you order the set menu immediately,” he wrote for The Guardian.

While people do often walk away or switch to another program as soon as the credits roll, plenty of others consider them an important part of the viewing experience. The music alone justifies sitting tight for a little while longer, and the credits provide the perfect opportunity to contemplate whatever you’ve just seen. They also pay homage to the hundreds of people who brought the project to life. And, as the Marvel Cinematic Universe always reminds us, not all movies actually end when the credits start to roll.

Netflix doesn’t outright prevent viewers from watching the credits. If you click on the minimized box, the credits will spring back to full screen and remain there until the very end. But if you take too long fumbling for the remote, you might miss your chance—Netflix’s autoplay feature often begins the next preview in mere seconds, in which case you’d have to go back to your home screen and restart the previous program to see the credits.

A video producer named Mark Boszko got so fed up with the arrangement that he launched a petition on Change.org. He’s not asking Netflix to get rid of its end-of-program advertisements across the board; rather, he just wants the platform to let viewers choose to have the full credits play as their default setting.

Boszko’s petition is evidence that he’s far from the only person who cares about the cause. So far, more than 10,500 people have signed it—you can do so here.
