They are sweet. Just a few big one hehehe.
I hope the rocket stove will well. I have come across a soil battery, we actually knew a man in Taos who was building many for the Pueblo there, but it’s probably beyond the scope of what we’re endeavoring here.
Have you looked much into it?
I have looked into it but never tried to build one. I have some ideas for if I was ever going to try it. I think that it would definitely require another heat source than just the sun over the summer... The concept is solid in my mind but I would definitely go at it without the idea of it being a passive heating system. Some point in my life I will build one though!!
