I had this great idea of using sheet metal to more effectively direct heat from a wood fire to my stock pot, in order to make the hot tub heating more efficient. It worked incredibly well... until the aluminum that made up the sheet decided to melt! I may retry this with the surprising amount of bricks that used to be buried underground in my yard, though I was hoping for a more lightweight (albeit still zero-cost) solution.
