Contrary to whatever it is the title brought to mind, this post has nothing to do with gold. Nothing. Nada. Zip. Those glittering beans on the picture? Polished stainless steal shells. What do they do? Why, keep the coffee experience more satisfying. Warmer, hotter, cooler, richer, longer. Confused? Let the Kickstarter page explain.
This amazing feat of thermodynamics happens thanks to a special non-toxic material sealed within the polished stainless steel shell. This material is designed to melt at 140 degrees Fahrenheit, and absorbs a lot of energy as it melts. This is how Joulies cool your coffee down three times faster than normal. Once it reaches this temperature, the special material begins to solidify again, releasing the energy it stored when it melted. This is how Joulies keep your coffee warm twice as long.
The better insulated your cup, the better Coffee Joulies work. Simply using a lid goes a long way. This is because less heat is lost to the environment, and more is stored within the Joulies themselves. In a ceramic mug Joulies will keep your coffee in the right temperature range for only a few minutes longer than usual (because mugs are such poor insulators – designed to keep your hand from being burned, not to keep coffee warm). Of course this isn’t a problem when you’re rushing to get to work in the morning and Joulies help you drink your coffee three times sooner.
These hand made patent pending wonders are a hobby on-the-side for engineers Dave Petrillo and Dave Jackson. For the good stuff, keep in mind the more you pledge the sweeter the Joulie deal.
