The Sage RF cooking appliance is like a super-precise microwave

Add as a preferred source on Google

We’ve all experienced the joys of microwave ovens: burned popcorn, rubber chicken, a plate of food with bites that are alternately scalding and cold.

Freescale Semiconductor is out to change that with its new Sage microwave oven concept on display this week at its Freescale Technology Forum in Austin, Texas. The solid-state RF microwave uses radio frequency (RF) emitters instead of magnetrons to heat our goodies.

Freescale says that unlike microwave ovens with magnetrons, solid-state RF cooking can control where, when and how much heating energy is directed into food – enabling more precise cooking for improved consistency, taste and nutrition. This fine-tuned heating capability helps prevent overcooking, which can destroy nutritional content, reduce moisture, and waste energy.

 

By precisely controlling the location, cycles, and levels of cooking energy, the appliance will bring food from a raw or frozen state to a cooked temperature rapidly and without intervention. In addition, convection heating capability enables browning and crisping. The oven concept can support a wide array of cooking types and qualities, from searing to browning, baking, and poaching.

The design also enables new form factors like round microwave ovens, as well as products capable of cooking multiple dishes and items at the same time within the same appliance.

Freescale says the RF technology does not interfere with your home’s wireless RF and Wi-Fi signals, as some microwaves can do.

Freescale’s Sage design also connects wirelessly to a home router for Internet of Things capabilities and smartphone app features. Freestyle eyes scenarios with supermarkets, farmer’s markets, and other vendors delivering a host of Internet-ordered meal options to homes for quick and easy cooking in RF microwaves. Perhaps all that food will be delivered by smartphone-connected drones?

Hands-On with Haier at IFA 2026: There’s a camera in everything
From AI-powered fridges and washing machines to robot-assisted laundry, Haier’s vision of the smart home is getting seriously intelligent.
Haier Booth at IFA 2026

If I had to sum up Haier’s entire IFA showcase in one sentence, it would be a camera here, a camera there, and a camera everywhere. But after spending some time with the products, I realised the cameras aren't really the point. The interesting part is what Haier is doing with all that visual information.

From fridge to oven, AI is watching

Shark ChillPill first look: A surprisingly cool EDC route to beating the heat
A triple-mode cooling gizmo that deserves a spot in your EDC kit.
Person using the Shark ChillPill.

I first saw the Shark ChillPill on social media and thought it looked like a pretty interesting little gadget to try. Taking it out to the golf course on a warm day seemed like the right way to put it through its paces, because the ChillPill has three different ways of cooling you down: a high-speed fan, a mister, and a chilling plate that makes direct contact with your skin. You can't use all three at once, which is a little disappointing, but I was curious to see how each one worked in the heat.

How strange it is to be anything at all: A first look at physical AI through Intern 2
I unboxed Autonomous Intern 2 expecting to meet an AI agent. Instead, it got me thinking about what it means for AI to have a physical presence at all
Triangle, Lamp, Tent

There is an episode of The IT Crowd where Moss and Roy convince Jen that a small black box with a blinking light contains the entire internet. She carefully carries it around like some impossibly important piece of technology.

Intern 2 gave me a little of that feeling.
