2013 July-August, Lee S. Langston, “The Adaptable Gas Turbine”, American Scientist:
- Turbines have been around for a long time—windmills and water wheels are early examples. The name comes from the Latin turbo, meaning vortex, and thus the defining property of a turbine is that a fluid or gas turns the blades of a rotor, which is attached to a shaft that can perform useful work.
- A wheel with buckets used to raise water.
