Wind Turbine Output Boosted 30% by Breakthrough Design

Passive structure design of “Wind Energizer” by Leviathan Energy reportedly increases wind turbine efficiency 30% in field tests.

Technological advancements in wind energy efficiency have generally come incrementally and usually made via a process of increasingly large wind turbine blades. Put simply, the model has been: longer blades = more output per turbine.

But that pattern of incremental improvements may be a thing of the past if Leviathan Energy has anything to say about it. Leviathan Energy has completed initial testing on their Wind Energizer unit and is reporting gains in wind turbine output in the ballpark of 30% — and as much as 150% at lower wind speeds.

The principle theory at work is that by placing passive objects around a wind farm it will change the circulation around a large wind turbine. The advancement is not in the turbine itself, but rather in the area around it, as such, units can be adapted to any wind turbine from any manufacturer.

“This is a disruptive technology,” Leviathan Energy CEO Dr. Daniel Farb told me via telephone from Israel last week. “We are changing the environment of the wind turbine; this is a very different approach.”

Farb is a bit of a modern day renaissance man. Trained as a medical doctor—an opthalmologist—he also has a business degree, and perhaps most importantly, a real determination to make innovations in renewable energy. “Sometimes people are able to develop ideas that other people that may have missed by taking a fresh perspective on something,” said Farb, whose team at Leviathan Energy also makes a vertical axis wind turbine and small hydroelectric turbines.
