The Puck uses heat transfer to charge your handset

The concept of using heat transfer to produce usable energy to help you recharge your phone is behind Epiphany Labs' onE Puck, which is now looking for funding from the Kickstarter site. Yes, the product looks like a hockey puck with one side in blue and the other in red. To generate the power, if you have something hot like a cup of coffee, you put it on the red side. If you have something cold, like a cool mug of beer, you put it on the blue side. Enough energy is created to fully charge your phone. The onE Puck will work on iOS and Android devices.

Interested? On the Kickstarter site (click on the sourcelink), the different funding options are explained. While the idea is to retail the onE Puck for $150, a pledge of $99 or more will reserve for you an Epiphany onE Puck, which is expected to be available March 2014. Once the funding goal has been reached, you will also receive a t-shirt and a windshield sticker. Shipping is free in the U.S., $15 elsewhere. Backers can pledge $135 and receive free engraving on their device.

Epiphany is looking to raise $100,000 by April 6 to put the onE Puck into production. As of Thursday, they have raised just shy of $25,000.
