What is a Whirligig?
A whirligig is a device similar to a pinwheel that is usually hand held and spun by the wind. The whirligig spins on its pivot in a circular motion as air moves through it.
History
Weather vanes and whirligigs evolved from the simple and practical wind vanes that were used in ancient times. Wind indicators were important to farmers, sailors and anyone else dependent on the weather in their daily pursuits. Whirligigs are mentioned in early colonial records for their function as a wind determining instrument.
Whirligigs in Green Technology
There has been a growing focus on renewable energy and finding ways to harness the wind to generate unlimited energy. Wind turbines use the same dynamics and a design similar to whirligigs and windmills, both of which are used to harness wind power. There are several wind farms across the United States that are utilizing windmill and whirligig-type devices and technologies to generate electricity.
Whirligig Lawn Ornaments
Whirligigs add kinetic motion to a yard or garden and they come in an endless array of designs, shapes, and colors. Some are whimsical, comical, or just decorative folk art. Some gardeners believe that whirligigs act similar to a scarecrow, keeping birds and other pests out of the garden.
Types of Whirligigs
There are both non-mechanical and mechanical whirligigs. Non-mechanical whirligigs have wings, blades or flipper-type appendages that catch the wind and spin, while the mechanical whirligigs have a fan or propeller-type mechanism that sets the whirligig into full motion-action.
