With over 300 specimens, the Museum of Engines and Mechanisms of the University of Palermo collectively narrates the evolution of engine technology. This collection of engines, from water-powered devices, through the era of steam and reciprocating engines, to jet turbines, includes engines that once served to power pumps, factories, automobiles, airplanes, and ships.

The first wave pool in North America to consistently generate 3-5 foot spilling waves suitable for surfing

Big Surf Waterpark uses 15 gates that empty water into a 2.5 acre lagoon with contours that replicate a natural beach. Waves are produced by pumping water to a pre-selected height and released through underwater gates. The water released breaks over a baffle (similar to a natural reef), forming one wave per cycle. Water is recirculated to the lagoon through pumps.

A drive system that keeps the antenna pointed with millimeter precision regardless of factors such as environmental change


The Arecibo Observatory has the largest radio telescope ever constructed.  Maintaining the greatest electromagnetic wave gathering capacity of any telescope, it has been an essential tool in modern astronomy, ionosphere and planetary studies.

Apollo astronauts who ventured outside of the protective confines of their pressurized capsules faced a number of hazards, among them: exposure to cosmic debris, solar radiation, and surface temperatures that widely varied. The suit also needed to accommodate a wide range of motion to allow the duties of the missions to be successfully accomplished.

Referred to as the "catalyst of the Industrial Revolution," textile manufacturing helped to transform the American economy from an agricultural to a manufacturing economy. It led to transitions from human to mechanical power and from wood to metal construction. Population shifts resulted from significant numbers of people moving from rural areas to work in urban factories. The collection of tools and machinery housed at the American Textile History Museum (ATHM) represents a collection of ideas which developed during this period.

Experimental Breeder Reactor I
Society: IEEE Main Category: Mechanical Sub Category: Nuclear Era: 1950-1959 DateCreated: 1951 EBR-I Building Arco State: ID Zip: 83415 Country: USA Website:,_1951 Creator: Zinn, Walter

At this facility on 20 December 1951 electricity was first generated from the heat produced by a sustained nuclear reaction providing steam to a turbine generator. This event inaugurated the nuclear power industry in the United States. On 4 June 1953 EBR-I provided the first proof of "breeding" capability, producing one atom of nuclear fuel for each atom burned, and later produced electricity using a plutonium core reactor.

Wright Field 5-foot Wind Tunnel

Wind tunnel testing of aircraft models is essential to determine aerodynamic parameters such as lift and drag. The 5-foot Wright Field wind tunnel is an early example of the modern wind tunnel, well known from the early 1920s to the late 1950s for its contributions to research and the development of nearly every major aircraft and associated hardware used by the US Air Force and its predecessor, the Army Air Service.

Smaller and cheaper than a triple-expansion vertical engine, the horizontal cross-compound pumping engine, Pump No. 2, ran at relatively slow revolutions and was considered the height of engineering from the 1890s to World War I. This pumping engine at the York Water Company was built by the Worthington Pump & Machinery Corporation, Snow-Holly Works, Buffalo, New York.

The convenient dry-copying process for printed pages is among the truly revolutionary inventions of the century. In 1937 Chester Carlson, a New York patent attorney, developed the concept of applying an electrostatic charge on a plate coated with a photoconductive material. On November 22, 1938, Carlson dusted powder dyed with evergreen spores across an exposed plate and transferred the imprint to the surface of a paper.

Wright Flyer III

The 1905 Wright Flyer III, built by Wilbur (1867-1912) and Orville (1871-1948) Wright, was the world's first airplane capable of sustained, maneuverable flight. Similar in design to their celebrated first airplane, this machine featured a stronger structure, a larger engine turning new "bent-end" propellers, and greater control-surface area for improved safety and maneuverability.
