The common approach to capturing wind energy more efficiently has been to make wind turbines bigger. Larger blades sweep a larger area and* capture more wind. Therefore, more output per turbine. But new advancements are focused on improving the way wind gets to the blades, rather than increasing their size.
It's called the Wind Energizer. According to Leviathan Energy, the company behind the breezy design, the Energizer can increase wind turbine output 15-30%. And as much as 150% at lower wind speeds.
Think of it as a donut-shaped wind amplifier wrapped around the base of a turbine. The steel and plastic skirt structure helps direct wind flow from the turbine base to the blades, where it's needed most.
Not only does it help the blades do what they do better, it also eases the stress on crucial turbine parts. Extending both blade and gearbox life span by up to three years, says the company.
And the Wind Energizer can be custom fit for any size turbine. The company says it expects wind farms to see a return on their investment in just 1-3 years.
