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.
