Sick of getting caught short without any charge on your phone? Enjoy a hot coffee or tea while your working at the office? If so then this device could help harness the energy generated from you brew and turn it into charge for your phone.
The Epiphany One Puck charger is a small charging pad that generates a charge for a number of mobile phones using heat from a cup placed on top of the pad.
At the moment the product is not yet commercially available but the company have exceeded their target on the cloud funding site Kickstarter, they say the finished USB charger will charge almost all modern smart phones.
One of the more interesting parts of the charging pad is that it can actually generate energy from cold drinks as well as hot.
