Now, charge your cellphone with the power of a drink

Washington: A new device that can charge your mobile phone with a hot cup of coffee or a cold beer mug has been developed by a US company.

The company claims that the two-sided Epiphany onE Puck converts the warmth of your hot cocoa or iced beverage into power for your phone. The lightweight device is portable enough to store in your purse or day bag for emergencies.

The device uses a Stirling engine powered solely by heat disparities to generate the electricity to keep your phone up and running, 'Gizmag' reported.

Stirling engines were actually invented in 1816 as a rival to the steam engine, but its use was limited to low-power applications for a long time.

Epiphany Labs is using modern materials to use the technology in a rather different way. The most obvious evolution comes in terms of size.

The working prototype of the Epiphany onE Puck is not much larger than the bottom of a cup, so it's small enough to carry around easily.

The device has two sides - a blue side for cold drinks and a red side for hot drinks. According to its creators, a hot drink is the optimal way to charge a device.

It comes with a USB port that can charge any device that draws 1000 mA or less. This means it can charge iPhones, Androids, iPods and other USB-based devices.

Epiphany Labs claims that, in ideal circumstances, the device would be able to charge your phone at the same speed you would see plugging it in directly to a wall.

It will also work in less-than-ideal conditions, but if you are not placing a fresh hot drink on the Puck, you will have to wait a little longer for your device to receive a full charge.

The team from Epiphany Labs has a working prototype, and is turning to Kickstarter to get the funding needed for production.
