Various small steam engines are built and marketed throughout the USA and the world today. This includes engines producing several horsepower, typical for steamboats, etc. The last large US manufacturer of steam engines, Skinner Engine Company, went out of business about 1980, and the last large engine that they built powered a generator in a large central station power plant.
