He came over after World War II. He was in Germany learning from engineers when he was 16 years old. They taught him the method, and he did it for a while during the 1970s oil crisis. About a year and a half ago we were talking about the high prices and he said he might have to make his own fuel. I asked him what he was talking about, and he showed me how to do it. I did it for my family vehicles, and for friends, and it worked great. I thought I can actually teach people how to do this.
