The team of engineers working at the Power Practical was too much into coffee but was disappointed by a large engineering inequality – while the coffee was brewed at a temperature between 195-205 degrees Fahrenheit, the drinking temperature for most people differed between 120-150 degrees. To heighten this problem further, the disposable cups went on cooling the coffee too quickly while the insulated thermos mug kept it dangerously hot for several hours. So, they decided to sit and work out on a smart coffee mug that can simply keep your coffee at a drinkable temperature. The result that they came up with is a smart coffee mug called Jul that can keep coffee and tea hot as per your preferences. The team is now concluding a successful crowdfunding campaign for this project.
The heating element for this cup is placed right inside it between the outer and inner walls. There are two conductive rings at the base that closely align with charging coaster rings so that drink temperature is maintained at the comfortable level. This coaster runs with the help of a USB pin that gives an output of 5 volts. The cup has been fitted with an optional car charging coaster that perfectly fits in an ideal auto cup holder and also works through the USB. The temperature of the liquid inside can be regulated easily when the bottom piece is twisted between the 120 – 150 degrees marks. When the drink is hotter as compared to your drinkable temperature, the coaster will turn into amber color and as it cools down it will turn into blue as the temperature reaches the ‘right’ level it will turn white.
The lid, too, has been designed with three different configurations – the larger holes are for refilling or venting the drink, the smaller hole is for sipping and the fully sealed one helps in transporting the heated cup from one point to another. This cup has a capacity to hold 12 ounces liquid and the tumbler weighs approx. 10.5 ounces.
