The onE Puck by Epiphany is a coaster that charges your phone using heat or cold as an energy source. Yes, it also stops coffee rings on your desk. The charger has two different sides, one for hot drinks and one for cold beverages and magically (a code word for I don’t understand this stuff) charges your phone. This device could change the world. Currently on kickstarter, they are very close to their goal and will easily exceed it before the time allotted (another 46 days) Find out more here.
