...made of three stacked clay pots, some bricks, a ceramic floor tile, paint stir-stick spacers, and tea lights. Due to because of our building recently got bought in a sort nesting-doll-of-schmucks deal and the heat hasn't been turned on yet.
The pots like uh absorb and radiate heat I guess is the idea. Based on this video by youtube tinkerer desertsun02, whose works I am not qualified to endorse or recommend. This is all basically magic and I don't understand what's going on around me at any given time.
Going about 50 min now and is getting hot to the touch. Air quality TBD wrt burning parrafin also am i losing half this meager heat through the nearby window glass yes probably idk
