Dutch designer Flooris Schoonderbeek, invented this "Dutchtub" in 2002. Completely independent from any energy needs, it's about as easy as it gets for installation. Place it on site , fill with water, and load the attached furnace with firewood. Light. Enjoy.
I'm not much for hot tub experiences, but I really like the look of the Dutchtub. A cross between a giant coffee cup and a stew pot for cannibals.
