Where is the hottest spot above a lit candle? In the flame or just above the flame tip or some cm above the flame or other?
My question more precisely concerns the heat energy I can get from a candle. I can see that isn't necessarily the hottest part. So to make the question more accurate:
From which part/point of the candle can I get the most heat energy pr. time unit? E.g. if I was to warm something up, which part the candle would then be the most efficient heater?
