As far as electricity goes Steampunks usually also branches off following Tesla instead of Edison. Thus electrical power is often more advanced and produced using less resources. Tesla would have made power nearly free to everyone, destorying the Electric Company Edison had built because he was working on ways to beam electrical signals through the air, much like radio waves are now. If he had been successful we wouldnt He was also finding way to miniturize his coils while still retaining conductive power and safety. He developed the Violet Ray machine as he first miniture but was unhappy about its lower output so continued working. If he hadn't been ruined by Edison both personally and financially I'd say the world would be a very very different place. Sorry rambling now, I'll stop. Telsas kind of a hero of mine.
