Okay I'm writing a story and in it the main character is walking and his phone is about to die and he day dreams of a small handheld device that turns heat energy into electricity and calls it a thermoelectrical generator, he then looks online later and finds out there is a device that does that except it's called a thermoelectric generator, I've tried to find out what the power is but I'm not sure
