    Admin, where is edit option?

    It's mine.This TE Generator doesn't need voltage booster circuit. It runs on cheap candle (100 pcs for <2$) and reaches 4.5 V with no load*. Under load the voltage shrinks to 3.8 V with the show white LED light. The voltage can be increased by increasing temperature difference (only flame in this constriction), but it means lower efficiency because "the table" warms i.e. more temperature losses.
