Morphing Material Keeps Hot Coffee at Ideal Temperature
temperature controlled mug pcm 1  (image via: Miscpix)  Buying a
hot beverage can be a maddening experience. At first it’s way
too hot to drink, and then it cools down so quickly that you
don’t have a chance to drink it before it’s tepid and
unappealing. The same thing happened to German researchers Klaus
Sedlbauer and Herbert Sinnesbichler: while walking around an
outdoor Bavarian Christmas market, they noticed that their
mulled cider was never at optimal drinking temperature. So
rather than complain like the rest of us, they set out to find a
solution.  temperature controlled mug pcm  That solution is
phase change material (PCM). PCM is a wax-like substance that’s
already used in construction and clothing because of its
remarkable temperature-regulating capabilities. Sedlbauer and
Sinnesbichler reasoned that they could put PCM to work keeping
beverages at their ideal drinking temperature, whether that’s
hot or cold.  temperature controlled mug pcm 2
