Could This Be The World’s Most Perfect Coffee Mug?








Scientists call it the Goldilocks Principle.
It comes from the children’s story The Three Bears in which a little girl named Goldilocks finds a house owned by a family of bears. Each bear has its own porridge bowl, chair, and bed. Goldilocks tests out all three examples of the items, always finding that one of them is too extreme in one direction (too hot, too large) or the other (too cold, too small), and the one in the middle is just right.

In science, the Goldilocks Principle states that something must fall within certain margins, as opposed to reaching extremes. Astronomists call Earth a Goldilocks planet because it’s not too near or too far away from the sun, but it’s just right to support life. In medicine the Goldilocks Principle defines the ideal dosage of a drug—too small and it’s ineffective; too large and side effects will harm the patient. And now a chemical engineer and an industrial designer have applied the Goldilocks Principle to coffee cup technology. They’ve created what could be the world’s most perfect travel mug.

The Temperperfect mug makes use of a phase changing material sandwiched between thermal walls. It alternates between a liquid and a solid as it absorbs, stores, and dissipates heat. Dean Verhoeven, one of the mug’s inventors who spent the last 15 years making, testing, and improving prototypes, describes its groundbreaking temperature regulating mechanism:

This project was born of my frustration with not being able to drink my carefully-brewed, but too hot, coffee right after I made it, and it then getting cold before I had time to enjoy it. I wanted it just right.
I thought about this problem and had an inspiration: why not take the excess heat out of the too-hot coffee, store it in the wall of the mug, and then use it later to keep the coffee at a pleasant drinking temperature? I realized that this could be done simply by adding an extra layer of what I call active (“Temperfect”) insulation to a standard mug. This extra insulation layer absorbs the excess heat from your drink, and brings it quickly to a comfortable temperature. Later, it slowly releases that heat back into your drink to keep its temperature just right.

It seems that the world has in fact been waiting for hot—but not too hot—coffee.
The creators found an enthusiastic audience when they turned to the crowdfunding site Kickstarter. They were hoping to raise $23,500 to cover the cost of the production tooling that’s need to manufacture the mugs. Instead, that amount was pledged 10 times over by more than 4,000 backers and it’s allowed them to move straight from tooling to production.

The first Temperperfect mugs are planned to ship next summer. The company’s website can hook you up with a pre-order.
