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.

Ninja’s Hot & Cold Brewed System Is the Only Coffee Maker You’ll Ever Need

Update: The Ninja Hot & Cold Brewed System is on sale for $120 ($40 off) for Sam's Club members until May 19.

For people who just want a cup of joe to help them get out the door in the morning, the French presses, Chemexes, Aeropresses, Moka pots, and other specialized devices that coffee aficionados swear by probably seem more overwhelming than appealing. Ditto the fancy cappuccino machines at local cafes. That’s where Ninja’s new Hot & Cold Brewed System comes in: It was created to give coffee addicts a myriad of options with minimal fuss, not to mention minimal equipment. And it makes tea, too!

“Coffeehouses are known for having an endless selection, but current at-home brewers haven't given users the vast variety of choice we thought possible, and certainly not all in one product," Mark Rosenzweig, CEO of SharkNinja, said in a press release. "The Ninja Hot & Cold Brewed System changes the category entirely. This innovative system is more than just a machine you use in the morning; it's your all-day brewing partner.”

The Hot & Cold Brewed System comes with two baskets: one for coffee and one for tea. It knows what you're making to make based on the basket you insert, and the available options for that basket will light up. The machine allows the user to make six different sizes of coffee or tea, from a single cup all the way up to a full 50-ounce (10-cup) carafe.

And of course, as the name suggests, the system can make both hot and iced beverages. For coffee, it has five brew options: classic, rich, over ice, cold brew, and specialty (a concentrated brew for milky drinks like cappuccinos). If you’re making tea, you can choose between hot and cold brews optimized for herbal, black, oolong, white, or green tea.

When you select an over ice or cold brew, the machine automatically doubles the strength of your beverage so it doesn't get overly diluted by the ice cubes in the carafe. Even better, the Ninja can make cold brew in just 10 to 15 minutes, whereas other systems and methods typically take hours. (Hot coffee is brewed at 205°F, while the cold brew is made at 101°F.) And the system has a hot and cold frother that folds into the side so you can make barista-level lattes, too.

These bells and whistles sound impressive on paper, but how do they perform in real life? Ninja sent me Hot & Cold Brewed System to test for myself.

Ease of Use

Though it might look like something developed by NASA, the Hot & Cold Brewed System is designed to easily work with the twist of a dial and the push of a button, and it delivers. From loading in the correct amount of grounds with the system’s “smart scoop” to picking what type of brew you’d like, it’s simple enough to use even while bleary-eyed in the morning. It’s also easy to schedule a delayed brew so you can do the rest of your morning routine while your coffee brews. (Here’s the only drawback I can think of about this machine: When it starts brewing, it’s kind of noisy—loud enough to make my cats jump. It’s not a dealbreaker, but if you live in a small apartment and plan to brew coffee so that it’s ready right when you wake up, it might be something to consider.)

The system even tells you when it needs to be descaled. The “clean” button will light up, at which point you simply fill the water reservoir with descaling solution and water and press the clean button. A countdown lets you know how much longer the clean cycle will last.

Taste and Flavor

I swapped out an old, cheap coffee maker for the Hot & Cold Brewed System, and the difference was immediately noticeable. Whether hot or cold, the coffee made by the H&CBS was a better, smoother cup of joe. That’s due to what Ninja has dubbed Thermal Flavor Extraction automated brewing technology, which, according to a press release, “knows the precise temperatures, correct bloom times, and proper levels of saturation for every possible beverage combination to ensure a great taste every time.”

Whatever tech they use, it works. The coffee I make in this machine is consistently tasty. The rich brew setting works exactly as advertised, too, providing a richer, bolder flavor than the classic brew.

Features and Accessories

One of the best things about the H&CBS is the fact that it cuts down on waste significantly. Unlike other machines, it doesn't require any plastic pods or paper filters. Instead, it comes with two permanent filters, one for coffee and one for tea.

And the cold brew function is a game changer if you prefer iced coffee to hot. Not only does it brew quickly, but it eliminates the messy cleanup that comes with making cold brew yourself.

Typically priced at $230 for the thermal carafe version (or $200 for the glass carafe), the Hot & Cold Brewed System is significantly more expensive than a simpler drip coffee machine. But if you’re a cold brew addict looking to treat yourself, it’s worth it. Consider springing for the slightly more expensive thermal carafe model, which will keep your java hot or cold for hours. (I’ve left ice in it overnight and found cubes the next morning.)

You can get the Hot & Cold Brewed System on Amazon, Walmart, Macy's, Sam's Club, or directly on Ninja’s website starting at $160.

Springer Nature Has Published the First AI-Written Textbook

The first AI-written textbook is here, and its tech-heavy subject is exactly what you might expect from a machine-learning algorithm. As Smithsonian reports, the book, published by Springer Nature, is a 247-page guide titled Lithium-Ion Batteries: A Machine-Generated Summary of Current Research.

While it doesn’t exactly make for light reading, the fact that it was written entirely by Beta Writer—an algorithm designed by researchers in Germany—is a game changer. Sure, AI has dabbled with writing before, helping journalists pen articles and even crafting entire chapters for the Game of Thrones and Harry Potter series. (We highly recommend the riveting tale of Harry Potter and the Portrait of What Looked Like a Large Pile of Ash.) But this is the first time AI has authored an entire research book, complete with a table of contents, introductions, and linked references.

The information was pulled from Springer Nature’s online database. While the grammar and syntax are a little clunky, the book manages to get the point across. (Here’s one sample sentence: “Respectively, safety issue is apparently challengeable till now even after the first commercialization of lithium-ion battery.”)

With the exception of an introduction to the book that was written by Henning Schoenenberger, Springer Nature's director of product data and metadata, the finished product was left unedited and unpolished. This was done “to highlight the current status and remaining boundaries of machine-generated content,” according to Schoenenberger. The publisher hopes to experiment with AI-powered textbooks on other subjects in the future.

Artificial intelligence has certainly come a long way in recent years, and algorithms have been trained to carry out a number of oddly specific tasks. They can design beer, figure out the ingredients in your meal, find Waldo in a “Where’s Waldo” picture, and remake the music video of “Total Eclipse of the Heart.” In one of the more meta developments in tech news, Google’s AI even learned to make its own AI in 2017.
