Today the MAA students of the Introductory Studio “Wind energy machines” Tutored by Javier Peña, Rodrigo Rubio, Oriol Carrasco and Stefanos Levidis have visited the experimental wind labs of TechnoWind, located in Sant Guim de Freixenet (Lleida). Alvaro Ibañez and Josep Maria Pujol showed us the instalations that Technowind use to test their windmills, Technowind by Ficosa Renovables is a young company that offer energy solutions, specialized in hybrid systems composed by solar panel and windmills. The headquarters are located in in Rubí (Barcelona), where they design and fabricate vertical axis windmills . In Sant Guim de Freixenet, the group has the i+D lab, where they test the new models of wind turbines and new prototypes with different solutions in design . The biggest windmill that is being tested in the wind lab is able to generate 5Kw without any kind of noise. The visit ended under a horizontal axis wind turbine that allowed students to realize and understand one of the most important concepts of the introductory studio: energy scales.
