"Isn't the Isotope Thermoelectric Battery something quite simple? As long as you can get a long half-life radioactive element and a few thermoelectric chips, it's not hard to make this thing yourself!" Chen Xin responded to Zhang Chengguang's inquiry with a nonchalant attitude, hoping to brush this matter aside.
Seeing Chen Xin's nonchalant attitude, Zhang Chengguang felt a wave of difficulty and helplessness.
The principle of the Isotope Thermoelectric Battery is very simple; to put it plainly, it's about thermoelectric conversion. Even a primary school student could make one if given the materials and the principle was explained clearly. But the problem is that radioactive elements are controlled substances in Flame Country and even globally. Ordinary citizens find it hard to even see them, let alone buy them.
