It Buuuuuurns!: Scientists Invent Mug That Keeps Beverages At Perfect Temperature

August 23, 2009


Physicists have invented a coffee mug to keep your beverage at the ideal temperature for 30 minutes. What is the ideal temperature? Allegedly 58 degrees Celsius (136.4 degrees Fahrenheit). I beg to differ.

The key for this magic trick is physics and PCM--phase change material--an extraordinary substance used in construction and winter clothing. PCM is capable of storing and releasing heat or cold.

The perfect mug follows the same principle: It is made of hollow ceramics. Inside there's an aluminum structure--as you can see in the image above--which gets filled with PCM. When you pour in your hot coffee, the heat gets absorbed reaching your personal optimum level based on the amount of PCM in the cup's interior. According to Klaus Sedlbauer, head of the Fraunhofer Institute for Building Physics, you can customize this on manufacturing.

You want to know the ideal temperature of my beverage? It's called ICE COLD BEER. But I will drink it hot if I have to. Last summer I drank a case of beer that had been in the trunk of my car for a week. I peed fire, true story.
