    I'm a simple man. I just want heat and long burn times.

    You don't buy one, you make it. This is a basic barrel stove made out of a propane tank with a heat exchanger coil added. Inefficient and dirty, but possible as a DIY.

    That is really a neat idea and a cool little stove. I always admire things that were made for functionality. Thinking about life for millions in Japan and much of Asia right now, a simple, homemade stove like that could have a huge impact on a family and communities. That water heater is genius.

    I did not see any water pump or pressure regulator valves on the heat exchanger! How might that work?

    that piece of stainless 1 or 2" piping he's holding and then inserts into the back of the stove is just a simple heat exchange. And then if you look at the tub, he's got one hose up high and one down low. So it probably cycles the water using heat/pressure/gravity? Like a syphon I'd guess.

    Yes, looks like an open, thermosiphon loop.
