An idea of mine for a self cooling pot I had been tossing around for quite a few years but never got around to trying...
Based on an ancient technology used to preserve food but with Cp application modifications
A dear friend sent a nice cobra so what better time to try :-)
Pictures are self explanatory I believe
Porosity of the terra cotta is critical of course.
no moving parts and nothing to fail = elegant imho
Maximum ambient surface temperature detected by FLIR thermography 93.7f
thanks for looking,
I did not adjust for thermal emissivity or reflectivity so take the temps with a grain of salt.
