I had a choice: I could either learn about four-strokes or go stand in a corner and pout. I figured both two-strokes and four-strokes burn the same fuel, mixed with the same air, and perform the same four essential power-cycle functions of compression, combustion, exhaust, and intake, so they are really the same engine, packaged in two different ways. So I got over the change and learned about cam-lobe center angle and airflow through ports with poppet valves in them. I learned lots of interesting stuff. Now we are feeling the tickle of another big change, as governments and futurists tell us that electric vehicles can and must solve important social, health, and other problems, and must gradually replace today’s fleet of internal-combustion-powered motorcycles, cars, and trucks. Some people I meet are preparing comfortable corners in which they plan to stand and pout—no electric appliance cars for them! Others, like myself, are trying to learn more about this notional electric revolution, so I have tapped out this umpteen-part series on what I’ve learned so far. Necessary Realism Electric vehicle advocates proudly tell us their machines emit zero pollution. That is true only at the point of use ... Sources of Electric Power ... The Cost of Change ... Some believe that such developments as Tesla’s favorably reviewed electric automobiles prove that electric vehicles for all will soon materialize. They feel that Tesla’s national network of 116 “Supercharger” charging stations are just the first green shoots of “electric springtime.” That will happen if business can earn a competitive profit from it. Anyway, enough heavy stuff. Onward to the technology!
