Can thermal energy be used to produce electricity?

Satisfactory answer Elf Level 7 2009-12-28 Yes, I made such a design when I was in graduate school, but the cost is too high and cannot be put into production. If you are interested, you can contact. each other. Follow-up question: Haha, really? What is the temperature ? Is the palm of your hand warm enough? Answer: You are really joking. Assuming the temperature in the palm of your hand can generate electricity, all the electricity has been consumed. However, I never studied the minimum temperature, I mainly focus on improving the conversion rate and reducing losses. To give you an idea, it should be possible to produce electricity at over 60 degrees Celsius, but the most important thing is that the thermal energy is continuous. Additional question: Is the body temperature sufficient if the cell phone is kept inns pocket every day? I want to get a battery like this to prevent the cell phone from running out of power. Answer: I can only say that the current is weak. The technology is not good enough. This is another point that you need to know about the law of conservation of energy: energy will neither be created from nothing nor disappeared from nothing. It can only be converted from scratch. from one form to another, or transferred from one object to another. During the transformation or transfer process, its total amount remains unchanged. Do you think it is impossible for a human body to run out of energy? From a local point of view, after converting part of the thermal energy into electrical energy, this part of the body will cool down. Do you think it can be reconstituted in time? You know that there will be much higher radiation than ordinary batteries. Your idea is good, but at least thisis not possible with current technology or theory. First make a small solar charger. If you have an idea, I can sit down and support you.
