A simple copper oxide thermoelectric generator can generate hundreds of millivolts. Sixteen of them in series can generate enough voltage to light an LED. See more information at www.sparkbangbuzz.com What is happening? I have spent my entire life reading whatever technical books and articles I could find and can recall seeing only one book that says tells how to make something like this and none that explain how this device works. It would be safe to say however, that an explanation could be found in the institutionalized literature. Not being presently affiliated with any institutions, I do not have ready access to most of their literature which makes the cost of reading it prohibitive. So, I will offer my own take on what is happening. A thermocouple is generally thought of as being a junction between two dissimilar metals but it might be better to say that it is a junction between two dissimilar conductors. Touching the two oxidized wires together forms a junction of copper oxide to copper oxide. This is not where the action is. The copper oxide on both wires should be thought of as one solid conductor between the two copper wires - a very short one at that. This can now be seen as the classic two thermocouples back to back circuit. We have a copper - copper oxide junction on the hot wire and an opposing copper oxide - copper junction on the cold wire. With this in mind it is now easy to view this device as being a normal thermocouple circuit. It is easy to wonder how ...
