Snow Energy is a 100% sustainable lamp and a smart phone charger that you can take just about anywhere but especially in cold places! The design utilizes a thermoelectric generator that works by generating energy when there is a temperature difference between the upper and bottom sections of the unit.

The light bulb head serves as the vacuum flask for containing hot water to warm the heat pipe which is connected to one side of the thermoelectric generator module. The other side of the module is the spiral-shaped heat sink containing a rechargeable battery. After pouring hot water into the vacuum flask and assembling it with the other components, the user needs only to stick the heat sink into somewhere cold! Alas! The thermoelectric generator will create electricity based on temperature differences between the piece of the heat pipe and the heat sink.
