I should make a confession on this subject. Born in 1950 I was a child of the 60s. My father was an EE and a good one in addition to being a ham radio operator. As a child I wanted to be just like him and early on my life was crystal radios, look no batteries. The 1N34 Germanium diode was my best friend. I went to gas stations gathering old car batteries, remember those with the lead connectors between cells exposed? My mother thought it odd that when she washed my clothes they came out with holes in them. Damn that battery acid! Anyway I got two 12 volt generators from the junk yard and thought it was really neat that when I applied 12 volts to the output terminal they ran like a motor but in the reverse direction they turned as a generator. I was pretty excited about that. Think I was about 11 at the time. When I asked my father things he would generally hand me a book to read. I still have some of those books. So I figure if I use a generator as a motor driving a generator I have something for nothing. So I manage to lag the two generators to a board and used a V belt in an X configuration so my motor turned my generator the right way. I even found a voltage regulator for my generator side. Obviously it never worked but my father watched and of course handed me another book. This was just one of many of my failed experiments but from each I learned. Not that I didn't believe people but I was the type kid who had to see for himself. Years earlier I got a lesson from a Proctor Silex toaster. That was a shocking experience, never jam a butter knife into a glowing toaster element. Bad things happen.
