Right on both counts. Would be nice to use the wasted engine heat to warm
buildings, after running the steam turbine.

Heating stuff by running electricity through some wire is not an efficient
way to produce heat. It's more efficient to use the electricity to run
electric motors in a heat pump. At least, that's the way we heat water in
our building. Burning fuel in an internal combustion engine is not an
efficient way to produce rotary motion. Isn't most of it wasted heat?
