How it Works

This low cost solid state wind power generator turns the flexing of an omnidirectional shaft directly into electricity, using piezoelectric materials.


A tall flexible stalk is surrounded with many embedded piezoelectric discs that are alternately sandwiched in-between rigid backup plates. These piezoelectric structures (toroids) compress and stretch when flexed in any direction, converting any motion directly into electricity with no intermediary mechanical generators, transmissions or propellors. A weighted wind-capturing tip can sustain the energy output from a single gust of wind by the continuing oscillation of this inverted pendulum after the gust fades. In light winds the power extraction would be maximized while remaining robust in high winds.

Highly Leveraged Force = High Pressure = Peak Piezo Power


This is a simplified formula that estimates the potential vertical forces generated near the base of a windulum. Assuming a wind force F of 500 pounds, a height H of 100 feet, and a width W of one foot, we can generate a compression pressure C of 50,000 pounds. This is the force available to squeeze and stretch just one of the many piezoelectic discs in the stack.
Remember that only 500 pounds applied to one cubic centimeter of quartz produces over 12,500 volts.

The Windulum's power output increases exponentially as models increase in size. Practical heights could range between 45 to 250 feet. More ambitious taller models could result in extraordinary output and efficiency.


Maximum pendulum action is achieved by optimizing a weighted, wind-catching tip. The sphere shown here represents a placeholder for optimal designs to be researched.
