Yi-One smart mug will cool your coffee just enough for you to drink it

Yi One Introduction Video

In today’s busy 24/7 world, who has time to wait for a hot cup of coffee to cool down? Certainly not the folks backing an unusual, but exciting new Kickstarter campaign for an innovative mug called the Yi-One. Updating the thermos for the new millennium, the Yi-One promises to keep your freshly brewed hot coffee at a scalding 200-degree Fahrenheit temperature, until you want to take a sip, at which point it will cool it to a drinkable 150 degrees in just three seconds flat.

“The technology is well proven and simple,” Yanming Wen, CEO of International Patent Acquisition, the company behind the technology, told Digital Trends. “The double-walled vacuum cavity and the cavity of the temperature equaling heat exchanger are partitioned by an insulated layer — with a centered hole for inserting of a solid and long-lasting drinking straw and a few communicating holes serving as coffee flowing passage. The temperature-equalizing metal of the cavity quickly and simply equalizes 20 to 30 cubic centimeters of scalding hot coffee that flows into the cavity by [50°F] within 3 seconds.”

In terms of the project’s origins, Wen tells a familiar story: That of the caffeine connoisseur forced to undergo an agonizing wait each day for their coffee to cool down.

“There was no way I could resist the alluring aroma of coffee that I needed so badly to kick-start my day,” he explained. “I often took a few sips of the hot coffee that ended scorching my lips and often spilled on me and my car seat. Sipping hot coffee kept in a mug on the go was always an inevitable trouble.”

If Wen has managed to crack this problem (which, as he noted, is one shared by millions of coffee drinkers), Yi-One will be onto a winner. We’ll wait until we’ve gotten the chance to test it for ourselves before proclaiming it a savior for coffee-drinkers everywhere, but it certainly sounds intriguing. As ever, we offer our usual warnings about the potential risks inherent in crowdfunding campaigns. However, if you’re keen to get involved, head over to the project’s Kickstarter page, where a Yi-One cup starts at $79. Shipping is set for early 2019.

Starlink V5 is here, and it’s lighter, smarter, and far more efficient
The next-generation satellite internet kit promises improved efficiency while maintaining high-speed connectivity.
Starlink V4 vs V5

Not every hardware upgrade needs to be about speed. With Starlink V5, SpaceX is betting that a lighter design and lower power consumption matter just as much. The company has officially introduced its next-generation Starlink V5 kit, featuring a smaller and lighter design with significantly improved power efficiency.

Frontier Starlink partnership featured

If there's one thing budget airlines aren't exactly known for, it's great onboard Wi-Fi. In Frontier Airlines' case, it hasn't offered in-flight internet at all. That's about to change. Frontier Airlines has announced a partnership with SpaceX's Starlink to bring high-speed, low-latency internet across its fleet. Installations will begin in early 2027, making Frontier the first ultra-low-cost carrier in the United States to adopt Starlink's satellite-powered connectivity.

For months, rumors have suggested that OpenAI's first hardware product could be a wearable AI device, or perhaps even the beginning of its long-term smartphone ambitions. As it turns out, the company's first gadget may be something far simpler, yet arguably far more ambitious. It will help control smart-home appliances, play media, answer questions, respond to messages, and tap into the range of capabilities offered by OpenAI's ChatGPT, according to people familiar with the matter.

OpenAI's first AI device could end up being a speaker, following plenty of hype that the company is actually working on a wearable AI device and might even launch a smartphone down the road. According to a Bloomberg report, the speaker will serve as a human-like AI companion that will integrate directly with the smart home ecosystem.
