Engineering Coffee at the Perfect Temperature

Monday, 19 August 2013 | by Pat's Picks

Coffee lovers will want to take note of the Wall Street Journal’s small business report this morning. There’s a little article about an engineer named David Jackson who was so inspired after burning his tongue on his morning latte every day that he and a partner developed something called Coffee Joulies. The metallic coffee beans are made of “phase-change material”—something that changes its state based on temperature—and absorb any access heat so your coffee remains at the perfect 140° F. When it gets too cool, the beans release the heat, keeping your cup hot for five hours.
