蜡烛是日常生活中的常见物品。蜡烛发光、发热,理论上可以把它的光能与热能转化为电能,这是一个很有意思的课题。笔者尝试对该课题进行分析,研究蜡烛发电问题。蜡烛内部能量的储存形式主要是化学能,通常情况下其能量输出形式是内能和光能,能量输出特点是输出功率小、输出能量不稳定。该课题的研究核心就是利用小型热源进行发电,难点在于蜡烛能量输出功率低且不稳定,利用起来困难。一、实验方案的初步设计 Candles are common items in everyday life. Candle light, fever, in theory, can its light energy and heat into electricity, which is a very interesting topic. The author tries to analyze the subject and study the issue of candle power generation. The internal energy of the candle is mainly stored in the form of chemical energy. In general, the energy output forms are internal energy and light energy. The energy output features that the output power is small and the output energy is unstable. The core of the research is the use of small heat source for power generation, the difficulty lies in the candle energy output power is low and unstable, difficult to use. First, the preliminary design of the experimental program
