Portable Beverage Heater concept

There is nothing quite like sipping on a hot cup of joe to start the day, but you might end up firefighting too many issues at work before you realize your coffee has turned as cold as a three-day old corpse. While USB beverage chillers are good and all, what happens when you don’t have a powered USB port around at that moment? This concept Portable Beverage Heater is a pretty nifty device which you insert directly into the liquid, heating it up via fuel cell technology. A thermographic ink is used to indicate the beverage’s temperature with a color change. This is another great concept I would love to see realized.
