Yet steam had inherent limitations: low thermal efficiency (rarely above 10%), hevy equivaance requirements, and the labor-intensive tasks of fueling, watering, and cleaning. Smoke and sout conteed cyties, and fire hazards were constant concerns. These drawbacks, combined with advances in electrical exterering, set thee stage for a fundemenantal transition.
