I manged to find out a little more how a peltier is constructed, and I noticed the ceremic plate needed, and that there was something sandwiched between them. I was thinking I could use a set of two tiles for it. It's for testing purposes, so size isn't going to be an issue. Only power consumption and heat generation is my major concern, I don't want to make a fire on one side/ice on the other side ball playing with it.
Bismuth Telluride, what's another name for it? Like mercury is quicksilver, etc, or is there one? Do you happen to know off hand any other element base pair that could be combined to form a comperable substrate? And does it have to be cubes, it seems like using small balls/marbles could produce the same effect and be cheaper to produce then a cube.
I have access to lab equipment at school, so that's kind'vea plus on my behalf, and I'm not afraid to mess with stuff.
Any reason why I'd have to obtain 1000Kg? That's like 2000lbs of stuff there...and seems like a bit much for a small project.
I also found lots of peltiers for sale cheap, and I'm thinking of getting one and bandsawing it in half just to see what's inside of it.
...you should have seen my poor Loligo(squid) after lab...poor little guy...looked like he'd been put in a Ginsu blender ten times over.
