Practical workshops are organised as parts of undergraduate dissertation projects and are open to all students of NTUA. During these workshops small wind turbines are constructed from scratch by the students, a process which provides practical evidence of the ability to locally manufacture these small wind turbines by unqualified constructors. The students have the chance to get acquainted with different tools and techniques such as cutting and griding metals, arc welding, using hand carving tools for wood and making resin moulds. Also they get acquainted with using different materials such as wood, resins, iron and copper by winding coils, carving the rotor blades, casting the stator and rotors of the generator and welding the metal frame. To this date, four small wind turbines for battery charging and grid connection have been manufactured, with rotor diameters from 2.4m to 6m and two small hydro turbines of 350W nominal power, one for grid connection and one for battery charging with an iron core.
