By the numbers: McKenna school wind turbine
Following approval by the Mountain Home City Council last month, Richard McKenna Charter School moved forward to build the first wind turbine within city limits. The following is a breakdown of this alternative energy initiative.
1.8 --Total power input, in kilowatts, the turbine produces
3 -- Number of blades the turbine uses
8 -- Minimum wind speed, in miles per hour, needed to move the blades
12 -- Total diameter, in feet, of the turbine blades
43 -- Height, in feet, of the turbine's tower
55 -- Maximum wind speed, in miles per hour, the turbine can handle before it automatically shuts down to prevent damage
170 -- The turbine's total weight, in pounds
4,000 -- Cost, in dollars, of the actual turbine
15,000 -- The project's total cost in dollars
