Robert Spellman watercolor of A Splashing Dream of a Pelton Turbine

Pelton Turbine ~ airbrushed watercolor on paper


This illustration appeared on the cover of the September 1994 issue of Hydro Review magazine. The image is a type of hydroelectric turbine called a Pelton turbine. What you are seeing is not really what happens in a pelton turbine; they are enclosed in a spiral-shaped housing that resembles certain mollusks. The whole design of a Pelton turbine is a marvel of precise engineering and beauty. This illustration was done in watercolor with an airbrush.
