    Abstract : Today one billion people are living in non-electrified areas. A majority of the people are living in rural areas in developing countries where there are no possibilities, neither economical nor technical, for grid extension. Instead energy sources like wood and fossil fuels are used. READ MORE

  2. 2. Wind-turbine harmonic emissions and propagation through a wind farm

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Kai Yang; Luleå tekniska universitet.; [2012]
