Your morning cup of coffee may power you through your busy work day, but what if it could also power up your cell phone? The Epiphany onEPuck is an incredible phone charger that siphons energy from your hot or cold drinks. The disk incorporates a Stirling engine that runs on heat disparities, transforming the change of your coffee’s temperature into power for your cell phone battery. Stirling engine systems are nothing new—they were first invented in 1816 as a rival to the steam engine. But with modern technology and materials, Epiphany was able to create a new thermodynamic system that can be used on your desk at the office. One side of the puck is marked with a red logo, which can receive hot beverages. Coffee, soup or even candles can be placed on the puck (in a mug of course) and be connected to your phone to charge the battery. Cold drinks and ice can be placed on the blue side.
As your hot drink cools down or the ice in your soda melts, the Stirling engine turbine begins turning, which generates electricity for the charger. A cup of coffee has enough power to fully charge your phone, just while you drink it. Even better, the onE Puck is a perfect back up if you forget your charger or no outlet is in site.
