ThermoElectric Generator: USB Charger powered by a Candle

A home built Thermo Electric Generator (TEG) powered by a Candle. Also take a look at my other build: https://www.youtube.com/watch?v=gVeIqsgvfuM&list=UULUvPd1Qo0e6FmzULEbNX6w It's build by two TEC modules, one heatsink, some cooling paste, some m4 bolts, silicon, 5v Boost Converter with USB connector and some aluminium plate. The modules are based on the seebeck effect. When i lit up the candle and places it under the TEG i've built it heats up the aluminium plate and heats the lower part of the TEC modules. At the same time the heatsink cools down the upper part and causes a temparatur difference, it's this difference is the thing that makes that the generator to produce electricity.
