Scientists Invent the Perfect Coffee Mug

Scientists love coffee. More than anyone else, by some surveys. So in a way, it makes perfect sense that they would be responsible for what could be the greatest coffee-related invention since coffee-alcohol: a mug that keeps coffee hot—but not too hot—for hours on end.

The vessel is the brainchild of Logan Maxwell and Dean Verhoeven. The idea came to Maxwell in his final year of undergrad at North Carolina State University. For his senior design project, he designed a temperature-regulating coffee mug that happened to be conceptually identical to more sophisticated prototypes that Verhoeven had been working on.
