In the current make magazine issue #15 There is a project called the Seebeck Generator. I was wondering about the use of Peltier Cells. Can someone elaborate as to how they function? I mean can you get them in different sizes? Would different sizes effect the power output? If I took like 50 of them and somehow combined them could I get a higher yield? What if you used it in combination with something like Hydrogen? Ideally Hydrogen burns hot and if I had a large version of the Peltier Cell Could I use it to get a real power output? Possibly enough to power an electronic motor?
Just some random thoughts the magazine sparked.
