2009 Energy Prize Finalist

This concept suggests a wind generation technology that requires fewer generators than traditional models and employs hydraulic fluid to increase power output by storing and utilizing energy during periods of low wind activity.

In this design, rows of wind towers are connected by a piping system containing hydraulic fluid, as well as a catwalk to facilitate safe access. As wind turns the blade on each tower, a single piston or rotary drive system in the blade captures wind force and transmits energy into the hydraulic fluid. In turn, a hydraulic-powered gear transmission system shifts, causing the pressurized hydraulic fluid to flow in a single direction. The combined energy created within the fluid from the wind towers is transferred by the piping system into a series of holding tanks.

Each sealed holding tank contains hydraulic fluid at a progressively increased pressure. The final pressurized tank transfers kinetic energy of the hydraulic fluid to a single generator system, located at ground level for accessibility. After the energy has been used by the generator, the fluid automatically drains into a holding tank, where it is eventually re-pumped via a vacuum system to the lead wind tower and reused.

This technology eliminates the need for a nearby traditional alternative power source, as energy is indefinitely stored within the pressurized hydraulic fluid.

About the Finalist:

Alan started his own business at age 28 and has been running it for the past 23 years, along with renovating and selling real estate. He also designs and builds specialized industrial equipment specific to his company. Several years ago, Alan learned that sufficient wind exists in the United States to supply a significant portion of the nation’s current energy needs. Recognizing that the costs associated with current wind technology prohibit the full utilization of this renewable energy source, Alan began working on ideas for more economical ways of generating energy from wind technology and for storing energy during times of little or no wind.

Alan and his wife Mary live with their three children in Grand Ledge, Michigan. He enjoys spending time with his family, cooking, landscaping and reading about science, technology and history. His hobbies include physical fitness, Tae Kwando, and scuba diving. Books that he has read recently include "Internal Combustion" by Edwin Black and "Outliers" by Malcolm Gladwell.
