I just saw this on some site:

The Peltier junction is a solid-state thermovoltaic device. Current applied to the device will produce heat on one side of the device and a cold surface on the other side. Water placed on the surface will freeze or boil depending on polarity of applied voltage. Ideal for applications from 3-12 VDC -- grab a battery and let your imagination run wild! DOCUMENTATION INCLUDED!!!



Small Peltier Junction $15.00 (approximately 1.17"x1.17"x.12")



Large Peltier Junction $25.00 (approximately 1.56"x1.56"x.15")
I've read up on these things previously and they are like friggin magic to me. So, I dont know how reliable, specifically these couples are. I DO know that with the probe that was sent to venus (I think it was venus or saturn) they used a nuclear thermocouple to power it (using the reverse physics that this product uses). Would the current in the case be right for this?

I cant link directly to it but it is located here in their gadgets section:

OK, well I thought the second post was worth saying I feel stupid for posting this since peltier coolers(as this is called on the site) *ARE* thermal couple coolers, Which are widely used already.
