How can it work out? Either one or both components has to get drastically smaller. So far, the most horsepower out of twelve cylinders is about 4,400, and such locomotives on C-C trucks weigh over the 400,000-lb mark. Can we squeeze 4,000 horses out of an eight or six cylinder prime mover? On the transformer side, we are still limited by the equation VS/VP = NS/NP, so you can't reduce the number of turns necessary for voltage step-down. |
