So someone explain how the power used to spin this thing is made up by...spinning? Seems the 2nd law of thermodynamics is applicable here, but I'm no engineer.
Let's focus on their numbers: 38 cents per KWh for flat panel vs. shiny blue pyramid cost of 17 cents. Looks good!
Except that flat panel, e.g. crystalline silicon on a single-axis horizontal tracker, is under 10 cents per KWh. The panels alone cost--and this price is three months old--roughly 65 cents per watt (DC) for 2013 delivery vs. the $1.15 per watt for the blue pyramid...
