The Juno makes warm drinks ice-cold in under 2 minutes


When you’ve been writing about tech long enough, it’s hard not to get a little jaded at the iterative products that come out every year. It’s rare that something really makes me say ‘wow’ nowadays.

So color me surprised when one of the most impressive product demos I’ve seen in months happened to be a kitchen appliance. Unlike the things on your counter that heat things up, the Juno cools things down. Fast. It can chill anything from a can of soda to ice-cold temperatures in under two minutes, a bottle of wine in five. It can even cool down fruits and veggies if you’re so inclined.

I was able to demo a prototype, and the claims hold true. It’s sorcery. It’s science. It’s the anti-toaster.

The Juno is created by a company called Matrix, which specializes in thermoelectric devices. You may remember it for its body heat-powered smartwatch. Now it’s leveraging its technology to make sure you can always have a cold drink.

The device takes advantage of something called the Peltier effect to achieve its rapid cooling. My demo involved a prototype device that, unlike the final unit, was transparent to show its inner workings.

The Juno folks put a warm soda can in the machine – I confirmed it was at an unappetizing room temperature – in the device and water rapidly surrounded it. The machine swirled water around and spun the can rapidly,  essentially sucking the heat out of the soda.

A little over a minute later, the can emerged from its wash cycle as if it had been sitting in the fridge overnight. If I wanted it even colder, I simply had to leave it in the machine longer – it can apparently cool a drink down to just above freezing. The company then assured me the can wouldn’t blow up my face after all that motion thanks to fancy spinning calibration. I drank the can suspiciously, but there was no evidence of witchcraft – just a cold drink.
