> According to Wikipedia a candle can produce 77 watts of energy "combined." I guess that means 77 joules (1 watt = 1 J/s). Watts is energy/time. 77 watts for a candle sounds about right. That means it is producing 77 joules per second. The amount of energy released by burning such a candle is therefore proportional to how long it burns, which is proportional to its mass. The thing you are looking for is the specific energy, listed as 45 MJ/kg upthread. See https://news.ycombinator.com/item?id=26973765 for the rest of the calculation. |
