The Meriden project was built and is operated by New England Hydropower having a nameplate capacity of 193 kW and a capacity factor of approximately 55% over a 5-year running period. Archimedes' screw An Archimedes' screw, also known by the name the Archimedean screw or screw pump, is a machine used for transferring water from a low-lying body of water into irrigation ditches.

SS Archimedes the Archimedes' screw, named after Archimedes of Syracuse who lived in the 3rd Century BC. It was not until the 18th century however, and the invention of the steam engine, that a practical means of delivering effective power to a marine screw propulsion system became available, but initial attempts to build such a vessel met with failure. In 1807, the world's first commercially successful steam-powered vessel, Robert Fulton's "North River Steamboat", made its debut. As this vessel was powered by paddlewheels rather than a propeller, the paddlewheel thereby became the "de facto" early standard for steamship propulsion. Experimentation with screw
