I heard about how the modern diesel-electric trains are engineered and wondered what I could learn from their systems, and was just about shocked. My intent was a thought experiment on "could we build a better hybrid car?" And the answer is a resounding yes... just look at trains. All the research is already done, by train builders. They've done the math that says when to prioritize amperage over voltage for efficiency, and how to optimize various systems. And that's just one thing that I found massively impressive. (Now if only I could find the site I read, it was impressive.)
