Instructables member randofo, inventor of the flame-throwing jack-o'-lantern, wants to be ready for a longterm power outage. He has a lot of tea candles. But what if he needs light? Randofo found a way to use candles to produce it. He used a Peltier heat sink to transfer the energy of the flame into electricity--enough to power a small candle-shaped lamp. Brilliant!
