Editing Compressor (section)

====Air bubble compressor====
Also known as a [[trompe]]. A mixture of air and water generated through turbulence is allowed to fall into a subterranean chamber where the air separates from the water. The weight of falling water compresses the air in the top of the chamber. A submerged outlet from the chamber allows water to flow to the surface at a lower height than the intake. An outlet in the roof of the chamber supplies the compressed air to the surface. A facility on this principle was built on the [[Montreal River (Timiskaming District)|Montreal River]] at Ragged Shutes near [[Cobalt, Ontario]] in 1910 and supplied 5,000 horsepower to nearby mines.<ref>{{cite journal|last=Maynard|first=Frank|date=November 1910|title=Five thousand horsepower from air bubbles|journal=Popular Mechanics|page=633|url=https://books.google.com/books?id=-N0DAAAAMBAJ|url-status=live|archive-url=https://web.archive.org/web/20170326071901/https://books.google.com/books?id=-N0DAAAAMBAJ&printsec=frontcover|archive-date=2017-03-26}}</ref>
