Using a new, high-tech material, German scientists Klaus Sedlbauer and Herbert Sinnesbichler have developed a coffee cup that will keep your drink at the optimum temperature for drinking. Phase change material (PCM) was already in use as a building and clothing material because of its temperature-regulating capability. Now it will keep your coffee from going cold!
CM is able to absorb and maintain heat or cold for long periods of time. It melts when warmed and solidifies when cooled. Different PCMs have different melting points. If a hollow-framed mug were filled with PCM that becomes liquid at exactly 136.4 degrees Fahrenheit (the ideal drinking temperature for warm beverages) and the mug’s reservoir filled with a warm beverage, the PCM would absorb excess heat, bringing the liquid down to drinking temperature and keeping it there long enough for you to enjoy your coffee.
Sedlbauer and Sinnesbichler are looking for a manufacturer and distributor for their coffee cup. Link – via babycreativeblog
