Wind power has become the primary means of obtaining electricity in some countries, but huge blades and operational noise may not be suitable for installation in metropolitan areas. The "tempo" that you see like a window grille is located in Delft University, the Netherlands. It is the latest bladeless wind turbine developed by the school's researchers. It relies on the so-called Electrostatic Wind Energy Converter. When the positively charged particles in the wind pass through the grid wires, current is generated. Therefore, the power generating device is not bound by the shape of the appearance, and assembly and maintenance are relatively easy.
