“Thanks for this story and for calling attention to home wind power. The Mariah WindSpire is a cool looking device that has got allot of attention out there. But it's just one of many systems to look at. You see, Mariah WindSpire specification for Cut In Wind Speed is at only 9mph.
Mariah WindSpire is a vertical turbine which means low efficiency. These turbines create their own drag on the backside, one side catches wind, the other RESISTS wind, that's drag. It's VERY important to buy a turbine that can cut in at a lower wind speed. Buy a turbine without that backside continual drag. It's like driving a car with the brakes on.
By example: Compare to a WindEnergy7 wind turbine, stainless steel parts, three bladed horizontal design, based on proven wind farm design standards. It's a really good turbine to compare to, especially since it beats most any turbine in its class. WindEnergy7.com WE7-700 Cut in Wind Speed, UNDER 6mph, Compare to: Mariah WindSpire 9mph.....
Progressive systems like WindEnergy7 come with built in support for solar panels to make a hybrid wind/solar system. The WindSpire looks cool and they do work, before you spend on a system, you should note that in the most important specs, WindSpire is behind almost any competing turbine out there, look at specs for yourself. Also, many people commented on price/point. WindEnergy7 has systems at better cost and all their systems have built in support for solar power.

“The WindSpire also sits too low, which limits the wind speeds and subjects it to mechanical turbulence from nearby obstructions. Better to get higher, and use a bladed design that uses lift rather than one like this with so much drag.”
