In honor of Pi Day, can you guess the circumference of the rotor on this Haliade #wind #turbine? Hint: the rotor’s diameter is 150 meters. That’s enough to fit three full-sized soccer fields. Located offshore near Ostende, Belgium, the Haliade turbine can produce enough energy to power over 5,000 homes and save 21,000 tons of CO2 during its lifetime. Without pi, we wouldn't be able to #engineer and #manufacture cutting-edge renewable #energy #technology like this. #happypiday
