I'm pretty sure that's with a traditional coal boiler...might be more
efficient with a sterling engine but I don't have the physics chops to
calculate it. But a coal boiler at the base/top running an electric
generation facility feeding electric drive wheels would be even more
efficient and would allow the boiler+generator to run at more efficient
rates.
