Venger Wind Unveils World's Largest Rooftop Wind Farm in Oklahoma City

Venger Wind and US renewable distributor SWG Energy just installed the world’s largest rooftop wind farm atop the Oklahoma Medical Research Foundation (OMRF) in Oklahoma City. The project saw Venger Wind construct 18 V2 vertical axis wind turbines on the medical center’s roof as part of OMRF’s sustainability strategy to create a zero emissions research tower.

The omni-directional wind turbines have been integrated into the design of the building and precisely positioned to collect wind from both the North and South sides of the rooftop farm. The installation of the 18 wind turbines makes the entire project the largest building integrated wind energy system in the U.S.

Unlike most vertical wind turbines, which are relatively modest in size, the V2 wind turbines are massive. They stand 18.5 feet tall and are rated at 4.5 kilowatts each. Unlike conventional wind turbines that use energy from the grid to start, the vertical turbines start producing electricity at 8.9 mph, which is well below Oklahoma City’s annual wind speed average.

Venger Wind is a global clean technology company engaged in the design, manufacturing and marketing of small wind turbines developed to generate clean electricity. Their V2 turbines are based on the work of Finnish engineer Sigurd Johannes Savonius who first invented the Savonius wind turbine in 1922.

Speaking about the project, Ken Morgan, Venger Wind’s Chairman and CMO said; “This project took a lot of hard work and long hours from all involved. This is a groundbreaking success for Venger Wind and the small wind industry worldwide. The potential to provide wind energy at the point of use, within urban environments is a major paradigm shift from the typical large wind scenarios where multi megawatt systems are forced to be installed farther and farther away from populations where the energy is needed most.”

“The small wind industry still has a long way to go in educating ourselves and our customers on properly assessing and installing wind turbines on buildings. It truly is a whole new science that has emerged and we are very excited with the Architects and Engineers we currently work with whom are pioneering new concepts for wind turbine integration into buildings. The OMRF building is an exemplary example of what is possible.”

Pretty much all wind turbines are omni-directional, it doesn't matter much where they are positioned on the building roof or which direction the wind is coming from, but those square-section pillars all over the place will likely kill the already poor efficiency of such a turbine unless huge volumes of material is now spent retro-fitting the frames with fairings to duct the wind through them. They might as well have placed them in amongst a stand of trees, and they will probably never achieve close to their rated 4.5kW each during their working life.

Also, unless Singh is talking about home-made VAWT's, which these are not, then 18.5ft tall is not 'massive' or large compared to many commercial VAWT's out there.

"The small wind industry still has a long way to go in educating ourselves and our customers on properly assessing and installing wind turbines on buildings." He can say that again. Their intentions might be good, but cowboys like these give the wind industry a bad reputation. Wind turbines installed on or near buildings must either be installed on a tower that already comes to a point, or be raised up above the boundary layer of slow air created by such a rectangular building's obstruction to the wind.

The OMRF building is an exemplary example of doing it wrong. - FTFY

ZeitNews, please don't propagate crap like this, someone might get inspired to do something incredibly stupid.

Hey 4ndy,

You're negativity is disgusting. Why don't you go pick on the petroleum industry and the scumbags that are fracking away our fresh water resources. It's jerks like you that are not doing a damn thing for the planet and are sucking wind for a living. Get a life dude! You're an idiot ass!

So planting over a dozen trees and shrubs over the last few months and trying to germinate dozens more, while designing wind turbines and other systems using renewable materials, and helping people to understand how we can transition into a sustainable economy... is not doing a damn thing for the planet.

Well done for that well-thought-out response to my critique on this system that could have been far more efficient with a little prior forethought by its designers. I guess you must be doing lots more than me "for the planet".
