Aeropoint Small Wind Turbine Pays Back in 2-7 Years!

Aeropoint1 Aeropoint2

I ran across some news that Marquiss Wind Power just raised $1.3 M in series A funding, which, in and of itself, isn’t that big of a deal to me (because funding doesn’t = anything).  That said, Marquiss Wind Power has quite the value proposition with their ducted wind turbine product called Aeropoint, a product that comes in three sizes.  It’s a small-wind turbine built for commercial buildings of 1-3 floors.  Based out of Folsom, California, the company had encouraging results with the first three test turbines.  Actually, the results were so good the company claims purchasers should have a payback period of 2-7 years.  You’ll notice that depending on a lot of different factors, a 2-7 year payback is about 2x faster than the payback for solar. 

The Aeropoint Ducted Wind Turbine stands tall at about 19 feet and weighs about the same as regular rooftop mechanical equipment — no structural changes required.  The square frame, which rotates on an axis to face the wind, encases the star-shaped turbine blades.  Looks pretty good, right?  And Marquiss Wind Power estimates the price at $30k – $40k, depending on the model you choose.  Who’s first?

    Ouch…this design reminds me of the now defunct Vortec 7 (See, where the company could not market the economics of their turbines despite similar claims…

    It also reminds me of a technology we talked about previously called the WindCube.

    With these concentrator types of small-wind turbines, I think you’re right to exercise some skepticism, but Marquiss Wind Power claims to have 3 models in the field being tested with these results.

    So either they’re lying or they’re not.


    “2-7 years” that gap seems large. how can that be that far off?

    I used to think that myself, but the range is there because payback depends on location.

    Depending on the wind speed, local incentives for small wind, the price of the turbine, etc., the payback period will differ.

    Dear eco friend
    comes sunflower industries
    some major renewable supplier
    hope a life time cooperation
    well as moral principle we value
