I used the tag A Road to Carbon Freedom for this series because: Reducing carbon (fossil) fuel usage is but a small first step toward a rational energy policy, worldwide. The Prius leads the way with advanced coding and systems controls.
          Okay, maybe Toyota is not the leader, I just made that up (I could have been in Advertising!). I bought a Prius, and I am having a lot of fun groking now it works without consulting with the techs that designed the system. I am of the educational school of thought: Tis better to reason than to listen. Lectures can be so . . .
                       
          So, let us reason together.
