    Hello there everybody!! I was just planning to make a Small Thermoelectric couple. Will it work if i twist together the ends if 1 Cu wire and 1 Fe wire alternatingly And then heat the joints only? How many will be needed for generating 3 volts (50'C) and how long can it power the small led?

    Thanks in advance for your help!!
