Insert Coin: Epiphany One Puck uses heat transfer to charge your phone

_In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please [send us a tip](http://www.engadget.com/about/tips/) with "Insert Coin" as the subject line. _

It's the modern bar-goers worst nightmare. No, it's not that the pub is out of your favorite ale, nor is it that you're 0-for-6 with lame pickup lines. You've been texting, tweeting and checking in all night, and you're paying for it with that red sliver in the corner of the screen. So what do you do? Give up your primo spot at the bar and find an outlet somewhere in the corner? Not a chance -- it's time to pull out your coaster-sized Epiphany One Puck, set a cold brew upon it, and connect your phone for some juice. Who knows, the Puck might also help you break the ice.

The idea to use heat disparities for power is over two centuries old, and [we've seen larger concepts](http://www.engadget.com/2012/04/10/insert-coin-the-powerpot/) make use of thermo-electrics. The One Puck brings mobility into play, providing up to one amp of current to any device that charges through a USB cable, including Android devices and iPhones. Just place a hot object (a mug of cocoa) on the red side or a cold object (iced coffee) on the blue, then plug in your phone.

The team at Epiphany Labs has loftier goals than simply charging cell phones, but all good ideas have to begin somewhere. The first prototype is ready and Epiphany is looking to [Kickstarter](http://www.engadget.com/tag/Kickstarter/) to bring the project to fruition. An early pledge of $99 includes a One Puck expected to retail for $150, while a pledge of $135 adds some custom engraving, just in case you want to count out the possibility of a resale before you even take delivery. You can head past the break to watch the prototype in action, and check out the source link to peruse the project's funding page.
