As the saying goes "there's nothing new under the sun". Back in the 1942 Popular Mechanics shop notes highlights I included a plan for a waste oil heater. Mother Earth News developed a similar heater outlined in their magazine. "The Journey to Forever" project built a similar heater and Roger Sanders advanced the project plan by making some improvements that make it efficient and easy to use.
The information compiled in the pdf below all can be found on the site http://journeytoforever.org/. This is a great and inspirational site for the socially and environmentally conscious. You will find lots of hands on projects and ideas for energy alternatives. To quote from the site "The focus is on appropriate technology, sustainable energy, sustainable farming, family nutrition and local self-reliance."
While looking through my "Alternative Energy" file this morning I came across the above mentioned file that I put together many years ago when I first found the "Journey to Forever" site. The Shop Notes heater came to mind and it crossed my mind that anyone interested in that file would like all this additional information.
