Ducted Wind Turbine Provides Efficient Rooftop Energy |

A company named Marquiss Wind Power has successfully finished raising $1.3 million for development of its Ducted Wind Turbines. Unlike their much larger counterparts, ducted turbines are boxy and stand about 19ft tall. Despite what appears to be aerodynamic disadvantages, this shape actually allows the turbine to re-orient itself according to the direction of air flow; something that can be a bit random in urban centers. The ducting is intended to increase wind speed as it approaches the blades. According to the website, these factors combine to allow the power output from the MWP turbine to exceed that of any traditionally designed comparable turbine. From the article,
At the moment, two models are sold — one intended for areas with wind speeds of 6-10 mph, and another for higher average speeds. The turbines are intended for buildings between one and three stories tall.
It sure ain’t elegant — but there’s a lot of science at play with this design. I especially like that AeropointT500 can operate in low wind speeds. I have no ideas on price — but hopefully that $1.3 million will go a long way to fleshing this product out a bit more.

your product looks good by virtue of the fact that it works! I know because I built a fiberglass mold to produce a shroud for my wind generator on our sailboat. Also a parabolic dish in frp is quickly reproduceable for direct solar heating. I have other concepts for my Power tower and would love to see them refined and implemented into the mainstream. I have many contacts here in south fl with interest in energy production and comne to think of it I have visited an Island off marathon with an 11′ wind gen I’m available at 305 773 7594

This looks like a very good idea.Normally wind turbines require around 10 mph winds to function.If this design will work in lighter winds this is an impressive advance in technology.JM.

The rooftop wind turbines at WindEnergy7 are home, rooftop sized designs of Utility Scale Wind Power. You see, there is decades of design, testing, and engineering behind the three bladed wind turbine designs that are used in large scale wind farms. Since the 30% Small Wind Turbine Tax Credit was passed into law, rooftop systems are selling like hotcakes.
The rooftop wind system at WindEnergy7 follows proven technical knowledge of wind power. Their turbines stainless steel parts will last far longer than other plastic designs they compete with, tested to witstand up to 134mph wind, yet generate power at under 6mph! Have a look at a real durable turbine here.. rooftop turbine Trust me this rooftop system pictured here will not sustain high winds without tearing down a structure. This is a rooptop hazard more than a wind system.
WindEnergy7.com now has customer/dealers in almost 50 different counties across the US. If you are interested in home wind power, have a look at those links here on Pickens Plan.

Rooftop Turbines & Home Wind Systems

Home Wind Turbine Video survives and thrives in the winter of 2010. Creating lots of power during this harsh winter, storms like Snowmageddon, Snowacaine, Etc that were record setting winter storms, the rooftop wind turbine systems don’t even ice up. They sit atop my home’s roof making free green electricity. I think if you look at the videos of the WindEnergy7.com system where it’s cranking out power in a really bad wind storm, you’ll see how the American Made steel hardware might compare to these plastic small turbine competitors. After you see that wind storm video at WindEnergy7.com
Home wind turbines from WindEnergy7 LLC are great, they just do the job. I am really glad that I have the new HO 4.2kW system on my roof. It did really well all winter and everyone here is impressed with the system. I posted some pictures at Wind Power Forums and there’s some Home Wind Turbine Installer here that show my system running and being installe so easily on the rooftop.
