Water wheel

"Yes, yes, I'll tell you the road directly, it's it's straight on through the wood till you come to the big water-wheel!"

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.
