Farm realities and new revelations
Fire-powered off-grid lo-tech hot tub - This was designed by Floris Schoonderbeek. Floris made this lo-tech hot tub by harnessing fire to heat up the water. Firewood is placed in a spiral on the side that naturally circulates and heats the water in the tub. This way you can put it right in the middle of nowhere without having to worry about where to get power from.
Ick, I don't like this "permaculture wheel" at all - sounds like a proposal for an entirely new network of inflexible rules and regs that fail to take specific areas into consideration. Some general principals should be common sense, but I sure don't like having any kind of potentially dictatorial map laid out. This kind of thing always backfires - that's my personal opinion, for what 49 years of personal experience in similar attempts are worth.
