The Puck uses heat transfer to charge your handset

Raising funds at the Kickstarter site, Epiphany onE is trying to get enough backers to put the Puck into production; the Puck is a device that uses heat transfer to charge your phone; by applying heat to the red side of the Puck, or cold to the blue side, the change in temperatures produces enough power to help get your phone powered up...

So you charge your phone in exchange for then drinking luke warm beverages? Seems kind of pointless.

Your out camping have no where to charge your phone or tablet your bill up some water over a fire pour into thermos and place on pad and voila. There are tons more implementations for the device obviously. Being able to use cold or hot items to conduct a charge is quite impressive.

Let's say you have your beverage sitting on the table. It's undergoing heat transfer at all times because it's in contact with the atmosphere, which is usually at a different temperature than your drink. Some of this heat is also exchanged with the table you placed it down on. Placing this puck in place won't make your drink cool down any more quickly because your drink was already losing (or gaining) heat to begin with.

Very interesting concept. Does a physical object need to be in place, or can it operate on enough radiant heat/cold if sufficiently present?
I've got window sill in my home that in the winter time is cold enough to keep drinks frozen, but in the summer gets enough sunlight to make anything there hot to the touch. Might never have to plug the phone into the wall again with one of these,
In retrospect, I really need to look into talking to an insulation specialist. :-\
