Matrix Industries Shows Off the Juno, a ‘Microwave for Cooling’, at CES 2020

Tell me if this sounds familiar: You go into the fridge to get a refreshing cold can of your favorite beverage and, surprise surprise, someone forgot to restock the fridge.

Maybe it’s you. Maybe it’s your roommate. Whoever it is, you’re now the sad sack stuck drinking room temperature beer or wine from a can (and you do drink wine from a can, ok?) wishing someone just had a little more beverage planning foresight.

But what if you could toss that can or bottle into a ‘microwave for cooling’ and almost instantly have an ice-cold beverage?

That’s the utopia that Matrix Industries has in mind with their new Juno Chiller. The product is based on a technology called thermoelectric cooling, which longtime Spoon readers know is based on a principle called the Peltier Effect, which essentially pushes phonons from one place to another through electrical excitement and in turn can remove heat from, say, a refrigerator chamber or a can of pop .

It’s complicated to say the least and I’m not a particle physicist, but what I can do is shoot iPhone video at CES press events that shows you the technology in action:

Matrix is not the only company looking to apply thermoelectric cooling technology to new applications. Phononic has been talking up their solid state cooling technology for some time, but over the past few years have largely focused on displacing compressor-based refrigerators in commercial refrigeration environments.

Spoon readers may also recall others have talked about a “microwave for cooling” before. Frigondas, a startup based in Spain, pitched the idea of an actual microwave that would both heat and flash-freeze. It’s an intriguing idea if they can pull it off, but the company’s largely gone quiet ever since pitching in it 2017 and 2018.

Matrix, on the other hand, seems to be just getting started with their product and plan on releasing their home beverage cooler later this year. If you want to get in on the cold drink action, they’ve launched an Indiegogo for the Juno Chiller, which would allow you get the beverage cooling appliance for half off ($199) in August if everything goes according plan.

As you can see by the product hero reel below, the final consumer edition will look much different than the working prototype shown above, featuring a much taller chamber that will allow you to chill everything from a can of beer to a bottle of wine.

No More Lukewarm Beer! The Chilled Drink Calculator Helps You Cool Drinks Faster

Summer may be waning, but there are still a few hot days left before we put away our white pants and break out the sweaters. And while the sun is still out, you’ll want to down a frosty beverage, not some tepid libation. To help make sure your drinks are at their optimal cold temperature for EXTREME thirst quenching, look no further than the free, online Chilled Drink Calculator.

Just enter the type of beverage you are about enjoy (beer, soda, juice, etc.), the size and type of container it comes in (glass, plastic), what your starting point is (room temperature, outside), where you are putting it (fridge, freezer, ice bath) and how cold you want it. That sounds like a lot when spelled out, but trust us, it’s zippy to fill out.

Once you enter all those parameters, the Chilled Drink Calculator spits out how long it will take you to properly chill your beverage. This is especially helpful for those throwing any Labor Day parties and wanting to make sure all the drinks are at the right temperature.

If you aren’t so good at planning ahead and you find yourself with a bunch of room temperature drinks, the calculator also provides some chilling hacks like wrapping a wet paper towel around your drink container, using a salt ice water bath, and, if you are Bill Nye or some other scientist, dry ice.

How does the Chilled Drink Calculator work? From the description:

Despite appearances, this calculator doesn’t run on magic. Instead, it makes use of a much more powerful resource: physics! This calculator is an easy-to-use version of our own Newton’s law of cooling calculator that has been modified to include technical values for the most common combinations of containers and beverages.

Newton’s law of cooling:

T = T_ambient + (T_initial – T_ambient) * exp(- k * t),

which, solving for time (t), we transform into:

t = -log[(T – T_ambient)/(T_initial-T_ambient)]/k,

where

T [K]: temperature of the object at time t,
T_ambient [K]: ambient temperature,
T_initial [K]: initial temperature of the object,
t [s]: time spent cooling,
k [1/s]: cooling coefficient,

The cooling coefficient is equal to:

k = h * A / C,

where

k [1/s]: cooling coefficient,
h [W/(m² * K)]: heat transfer coefficient,
A [m²]: area of the heat exchange,
C [J/K]: heat capacity.

Duh.

The Chilled Drink Calculator was developed by University of Warsaw physics student Álvaro Diéz and his foodie pal Tibor Pal. It lives on the Omni Calculator site and is part of a collection of 843 free online calculators. The site even has other food-related calculators, like the “Do or Donut,” which tells you how much exercise you need to burn off after eating one of those delicious confections, the “Coffee Kick Calculator,” which helps you gauge your caffeine intake, and the “Perfect Pancake Calculator.”
