Johan Smit and Dhiradj Djairam at Delft Technical University have developed a wind energy convertor that transforms wind energy into electricity with no mechanical moving parts, no noise, no blades to kill birds – and it looks like it could be a modern sculpture.

The device consists of a steel frame holding a series of thin insulated tubes arranged horizontally. Each tube contains several electrodes and nozzles, which continually release positively-charged water particles into the air. As the wind blows the particles away, the voltage of the device changes and creates an electric field.

This animation shows how it works.
