In an interview with online tech magazine SolidSmack, Dave Petrillo discusses some of the hurdles he and partner Dave Jackson faced in the creation of Coffee Joulies, a product that uses phase change material to regulate the temperature of hot beverages.
"The phase change material was actually not that difficult to find," Petrillo said. "One of the hardest parts to making this project was getting the manufacturing of the rest of the stainless steel shell made in the USA. Forming and joining and sealing these beans shut so that they last a long time is definitely a difficult task. Much harder than we anticipated."
