Seeing that ominous red battery icon on your cellphone is a cause for concern, especially if you're nowhere near an outlet. A new device removes all worries by letting you charge your phone on the go using the beverage of your choice.
The Epiphany onE Puck uses a heat engine to power your phone. It's shaped -- and acts -- like a coaster. You place a hot or cold beverage on the surface and let your drink do all the work. Check out the video, above, for more.
The charger works best in extremes, so the colder or hotter the drink, the quicker your phone charges. Prototypes are available on Kickstarter for $115 and backers can get the choice to customize the charger with engraved text.

Its creators explain the technology is nothing new, since the onE Puck uses a Stirling engine. A fixed amount of gas is sealed inside and changes in temperature create pressure. Robert Stirling originally invented the engine in the 1800s, but Epiphany President Tommy Joseph says it can be used in new and innovative ways.
Joseph hopes the technology can eventually expand to power larger appliances and entire households. The company also plans to use the same system to improve water units and provide electricity.
