The discussion revolves around the availability and construction of thermocouples for power generation, particularly in the context of using them during hot weather. Participants explore both purchasing options and DIY methods, as well as the practical applications and limitations of thermocouples in generating electricity.
Participants express differing views on the effectiveness of thermocouples as a power source, with some asserting they are not suitable for generating significant electricity while others discuss methods to potentially enhance their output. The discussion remains unresolved regarding the practicality of using thermocouples for power generation.
Participants mention various assumptions about the construction and functionality of thermocouples, including the need for temperature differentials and the limitations of voltage output. There are also references to specific materials and methods that may not be universally applicable.
This discussion may be of interest to hobbyists, students, or anyone exploring DIY energy generation methods, particularly those curious about thermocouples and their applications in power generation.
0xDEADBEEF said:It's dirt easy. Solder or weld two wires of different metals together. Stick the soldered end into something that's hotter or colder then the other end of the two wires and that's enough so there is a minute voltage between the free ends.
Make a long zig zag of alternating wires between the two temperatures to multiply the voltage. This is called a thermopile. The Voltage is #&^#$ small, so unless you are planning a whole furry wire coat around something you are planning to get the thermal energy from, you will be able to run a quartz clock at best.
