We originally posted about Mariah Power’s Windspire turbine last year when its sleek, “propeller-free” design first caught our eye. The company recently announced commercial production, sales and shipping their small wind turbine. The bad news is the fully integrated unit is back-ordered for the next few months as Mariah Power tries to meet consumer enthusiasm for the product.
The Windspire is a vertical axis wind turbine, or VAWT, and as such, turns at a much slower speed than traditional “propeller-driven” turbines and is extremely quiet. With its sleek look and variety of colors the Windspire is one of the more aesthetically pleasing turbine designs. The company recommends installation on a minimum of 1/2 acre of land and an average wind speed of 12 mph to produce 2,000kWH per year. The unit takes just a few hours to install and is rated for winds up to 100 mph.
The fast growing wind power industry has seen many designs come and go so to ensure product reliability and standards the company has subjected the product to independent, third-party testing at Windward Engineering in Spanish Oaks, Utah (initial test results).
The fully intergrated, “plug ‘n produce” unit sells for a modest $4,995 (plus installation) and comes with a 5 year warranty.
