The Coolspring Power Museum will hold its summer exposition on June 18, 19, and 20.

Located in Coolspring, Pennsylvania, USA, the museum documents the early history of the internal combustion revolution. The museum contains the largest collection of historically significant, early stationary gas engines in US, as well as a few items that were driven by stationary engines, such as compressors, pumps, and generators.

The museum’s collection includes hundreds of engines housed in more than 35 buildings and outdoor displays. Engines range in size from fractional horsepower up to 600 hp (447 kW).

The museum’s collecting efforts are directed at filling technological gaps in the collection by accepting donations from private collectors and occasionally other museums. The museum also maintains a substantial library and archive related to the objects in the collection and to the internal combustion engine in general.

The American Society of Mechanical Engineers recognizes the Coolspring Power Museum as a Mechanical Engineering Heritage Collection.
