The design, launched at EWEA 2014 in Barcelona in a 139-metre version topped with a 2.75-120 GE turbine,is build around an “Eiffel-tower-like” lattice structure clad with high-tensilepolyester panels.

The technology could carve“a large slice” out of the price of a conventional tubular tower bystreamlining fabrication and transportation, while opening up the possibilityof ultra-tall 150-metre turbines.

“When we started doing thisproject, I and a lot of other people had reservations about how it would look.Seeing
