Step 2: Draw Lines on Barrels. Take time to carefully draw bisecting lines on the barrels. Draw lines on them using a compass and straight edge. If you don't have a big Harbor Freight compass like mine, you can use a string and a Sharpie as a compass. Don't cut across the spouts because the plastic is very thick there.

The Darrieus rotor is a type of vertical axis wind turbine (VAWT) known for its distinctive eggbeater shape. It consists of curved airfoil blades that are arranged in a vertical orientation around the central axis. Darrieus rotors are named after Georges Jean Marie Darrieus, a French engineer who patented the design in 1926.

This setup increased the turbines' efficiency by 15 percent. It also meant that the turbines could be more tightly grouped in a much smaller farm than horizontal turbines would allow. The increased efficiency comes from the way they take energy from the wind. "They suck some air, then they blow some air," Tzanakis said.
