Keeping That Cuppa Joe Hot All Day

10 January 2017

A material developed by an engineer from the University of Missouri is making it possible for people to enjoy their hot beverages for up to eight hours.

The mug takes about two minutes to cool to 140 degrees F.The mug takes about two minutes to cool to 140 degrees F.On the outside, Hongbin “Bill” Ma’s travel mug looks like an ordinary metal coffee mug. However, the mug includes a material that absorbs the initial heat of the coffee and brings it to an optimal drinking temperature. Then, as the coffee begins to cool, the material releases that heat back into the coffee, extending the optimal temperature for longer than a standard vacuum-sealed travel mug.

According to Ma, the mug takes about two minutes to cool to 140 degrees Fahrenheit, and it stays there for up to eight hours. Developed by Ma through his company, ThermAvant Technologies, the mug uses phase-change material and advanced heat transfer, which is capable of storing and releasing high amounts of energy. Because of its vacuum insulation, the mug also can keep cold beverages cold.
