Looking around the KickStarter universe and it becomes apparent that consumers want to charge their phones by any means necessary. There are chargers for wallets, paper towel racks, purses, and now thermoses. Thermoses? Yes, that metal double-walled container that holds the morning coffee now contains a 1,000 mAh lithium ion battery in the base that charges via the hot morning liquid. The device, the ThermaCharge, takes advantage of what is known as the Seebeck effect which creates power from of a difference in temperature between two surfaces.
Certainly sounds like one of the more outlandish projects we have covered here, and I would absolutely agree. But after thinking on it some more I can really see the times when this would be useful. Imagine going camping and being without power for a few days, but still wanting to be able to call a family member or keep in touch with civilization while out in the wilderness. Simply boil some water over the campfire and in a few minutes the ThermaCharge has enough juice to bring any standard phone up to 60% or 70% battery.
For those who do not hear Nature’s call as loudly as most the internal battery can be charged via conventional means for a quick mid-day pep charge. The biggest thing for a project like this is the price. The ThermaChare is definitely not a product that is worth spending a lot of money considering most people take their morning coffee mug into the office with them and there is no shortage of USB ports there. I could see this being really successful as a camping or hiking product or even for students who do not bring a laptop with them to class.
Fortunately, the smallest ThermaCharge is being offered for only a $60 donation, and the largest runs for a cool $75. For those who are just looking for a cheap gift there is also a non-thermal-charging version that comes with an internal battery which more than doubles the capacity of the standard ThermaCharge at 2,200 mAh. But considering that, even if the ThermaCharge is never used for the containing of a beverage, it is still a $60 thermoelectric power source; which is not something to take lightly.
