Research shows that the steam engine George Corliss built for the 1876 Centennial Exposition was 70 feet tall and weighed over 650 tons. The gearwheel alone weighed 56 tons and was 30 feet in diameter. It was the largest steam engine ever built and produced 1400 horsepower. It was used for many years and was eventually sold for scrap.
