Wind Energy Concept
A reader asks, “What do you think of this idea?”
Let’s do some math, and call the length of the blades x. the swept area of this device is 4πx2. The radius of one big turbine, assuming the blade tips of the little ones almost touch, is π(4x)2 or 16πx2.
Thus replacing the four turbines with one big one would quadruple the swept area (and thus the output), and greatly reduce the costs, by removing three of the four nacelles and all the other superstructure, and chopping out a lot of maintenance.
