Has anyone experimented with using kittylitter, bentonite clay, to insulate the heat riser in the drum?
Also I was wondering about water storage of heat to improve efficiency, anyone out there done anything like that? Thank You in advance

I wasn't thinking about using a pressure vessel to store heat as I am very familiar with the explosive potential of steam.
My idea was to use a layer of two of cob to insulate the heat exchanger tubes and act as a heat sink of sorts, then a waterproof membrane barrier then water. The temperature of the water will be considerably lower than boiling point, and would allow a much denser mass of storage.
Anyone done anything like this?
